Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a thermal transfer recording method using a thermal recording head or the like, and to an improvement in a recording apparatus therefor.

Conventional structure and its problems A state in which a recording medium and a transfer member having a layer of recording material to be transferred to the medium on one side of the base are used, and this recording material layer and the recording medium are pressed against each other. A recording method is known in which a recording material layer is selectively heated by a heating means to selectively transfer the recording material to the recording medium to obtain a record.

In this type of transfer recording, conventionally, the melting point of a part of the constituent material of the recording recording separation layer is selected to be lower than the heating temperature, and the melting of the material is used to transfer the material to the recording medium.

A typical recording device consists of a recording material containing a hue made of pigment and a low-melting point binder, and this is applied to the sorting surface of a heat-resistant substrate such as thin capacitor paper or polyethylene terephthalate sheet. A so-called wax-type transfer sheet is used as a transfer body, and a thermal recording head having a resistive heating element that is electrically controlled is pressed against the back side of this transfer sheet, and the heat generated by this heating element causes a selectively melting (melting) the binder through the body
transfer and adhere the recording material to a recording medium such as paper,
There is a thermal melt transfer recording device that records characters, figures, images, etc.

In this type of recording device, the temperature of the first layer of the recording material is raised from the back side of the substrate, so the recording material melts starting from the contact interface on the base side, and only after the recording medium side melts does it melt onto the recording medium surface. The recording material H becomes in a state where it can be recorded by θ'. Therefore, because the image is transferred discontinuously with a threshold value due to external heat generation energy above a certain value, it is a binary image with no intermediate tones. -Although it is suitable for recording, it has the essential problem that it is difficult to record unless there is a halftone with a continuous recording density that corresponds to the amount of heat generated energy applied.

For this reason, conventional thermal melt transfer recording devices perform multi-gradation recording using binary recording densities, such as the density pattern method and dither method, in order to accommodate the current expanding use of multi-gradation recording. Digital gradation processing methods are being considered.

However, in order to employ this divine gradation processing method, a large number of digital processing circuits are required, making the recording apparatus expensive. However, the resolution and recording speed] 7 of dither processing
It decreases in inverse proportion to the number of binary density recording dots contained within the Tochinox.

At the same time, in order to display the -C density with the number of dots using dot density as a unit, there are 1 in multiple gradations, but the display gradation is discontinuous digital, and continuous analog gradation display is discontinuous. It is possible.

In addition, conventional thermal melt transfer recording devices use the principle of melt transfer by electrically controlling the heat generated by a resistive heating element, which has the disadvantage of low recording sensitivity, high power consumption, and difficulty in high-speed recording. Improvement of this essential drawback is currently a major research topic.

Purpose of the Invention The present invention solves the essential difficulties in the recording method based on the principle of thermal melt transfer as described above7, makes it possible to record images with continuous gradation, and saves the same amount of human power and energy compared to conventional devices. 1. A composition book of the invention for the purpose of providing a recording method and a recording device that can perform transfer recording with a high density of bacteria and even density recording, which is faster than L and therefore consumes less power. The recording method according to the invention uses a recording medium and a transfer body that forms a solid recording layer at room temperature on one side of a substrate, and selectively transfers the recording material layer to the Y1 layer. It is configured to control the recording and selectively transfer this recording month onto the recording medium by pressure contact between the transfer body and the recording medium, and the melting point thereof is higher than the melting transfer temperature of the recording month. At least one selective method for each recording month is used, using a solvent material having the property of dissolving at least one of the constituents of the recording material and increasing its solubility as the temperature increases. Bringing the solvent monthly rate in a liquid state into contact with the recording monthly unit while temperature is maintained by temperature increase writing control, and selectively transferring and recording the recording monthly unit onto the recording medium using the contact as a medium. There are 4 temples.

Selective Jf temperature writing control (temperature increase recording control for short) for each recording month is based on heat conduction from the substrate side or recording medium side through light energy such as infrared rays or laser beams, or thermal recording head, etc. , using external incident energy.

In principle, the present invention differs from the conventional heat-melting transfer recording method in that the solvent is stored in a liquid state and the temperature is controlled to be recorded.
*-1 part and heat-dissolve at least one component constituting the recording material with a solvent to provide a transfer recording function for each recording month.

The present invention allows thermal dissolution of solvent materials by recording month! Continuous changes in the amount of recording material dissolved are obtained by utilizing the so-called positive temperature dissolution characteristic in which the dissolution 1w increases with temperature. Indeed, it is also possible to perform transfer recording by also using the melting transfer characteristics of the binder that constitutes the conventional monthly recording.

Note that the solvent 4,1 material is
In the rock drilling control process, a fluid liquid state has already been formed, and when it comes into contact with the heated material, it dissolves at least one component of the recording material.
It does not necessarily have to be liquid at room temperature; it may be solid, that is, solid.

Indeed, the solvent material may be composed of a single material or a plurality of materials.

Further, as long as it exhibits fluidity under the above-mentioned elevated temperature conditions, it is preferable for J3 to be completely liquid, but it is not necessarily limited to this, and even mixed paulownia wood containing a solid phase material may be used. , or may be in the form of a sol or gel.

For ordinary purposes such as ink recording of characters and images, the recording month constitutes colored material, but uncolored old material can also be used for other special recording as needed.

Description of examples Examples of the present invention will be described below.

Examples of recording materials that are solid at room temperature in the present invention include a dye-only type, a dye-binder type, a face-stitching inter'' type, and a dye/pigment mixed-binder type, for example when recording characters, images, etc. in color. Any of the types can be used.Of course 11
The dyes and pigments as colorants and the binder may each contain a plurality of materials, or the sintered binder itself may contain a surfactant, a plasticizer, a softener, and other auxiliary agents. That is, in the recording material, the binder is interpreted as a material other than the colorant.

In these four ink types, it is desirable that both the dye and penta are soluble in the liquid solvent material, but this is not necessarily the case; at least one component of the constituent material is soluble. It is sufficient that the solubility (including compatibility with 1 and 1) increases by 11 as the temperature increases for the solvent A'A in a liquid state.

In other words, in a dye-only type, part of the dye is part of the dye, in a dye-binder type, at least part of the dye or binder is part of the dye or binder, and in a pigment-binder type, part of the binder is part of the dye/pigment. - In the binder type, at least a portion of either the dye or the binder can be configured such that the solubility of the dye or the binder increases as the temperature increases. The reason is that by dissolving one component of the recording material, the transferability to the recording medium is improved, and the recording material can be transferred and attached to the recording medium.

As the colorant dye, when the liquid solvent Uf-'I is aqueous, water-soluble dyes such as acidic, basic, direct dyes, etc. are used, and when the liquid solvent material is oil-based, Oil-soluble dyes (solvent dyes) are used. The dye may be in powder, paste, or liquid form, but in order to increase its solubility in the liquid solvent A'A, a paste or liquid dye may be used.

For example, the dye is in liquid form, so-called liquid dye.
For example, the solvent material is alcohol.

glycol ether, ketone, ester r')i'
When containing 4'+ group hydrocarbons, MorJust Liquid dye is a trade name of Morton Chemical Co., Ltd., and the first former material is Ganlin, naphtha, kerosene, water-insoluble aliphatic or aromatic solvents. Similarly, the company's A
Automate L'1quid dye and the like are preferred materials.

As the colorant pigment, it is possible to use organic pigments or inorganic pigments such as those used in conventional melt transfer notebooks or ordinary paints and printing inks.

As the binder material constituting the recording material tJ'$-1, most binder materials used in ordinary paints, offset inks, and gravure inks can be used. However, if you apply and store the electrolyte on a sheet-like substrate in advance and use it as needed, it may be hardened due to deterioration due to air, moisture, light, etc., or it may harden naturally, using a solvent material in a liquid state. This may make heat melting impossible, resulting in deterioration and hardening.
It is necessary to select a so-called reversible dissolving material that does not harden naturally.

When the solvent material is aqueous, such as water, alcohol, or glycol, the binder is a water-based paint resin, such as an alkyd resin or an oil-free alkyd resin.

Epoxy esters, acrylic resins, melamine resins, etc. are good examples, and their trade names include Watersol, manufactured by Dainippon Ink and Chemicals.

When the recording solvent is non-aqueous, solid resins are preferable as the reversibly dissolving solvent, such as 100'I) carbonic acid resin, or natural resin-modified carbonic acid resin such as pine resin, natural resin-modified maleic acid resin, and natural resin. Modified pentaerythritol resin, etc. (for example, Dai 11 Ink Kagaku Kogyo Co., Ltd., trade name: Besokazai I), 2 petroleum resins (for example, Nippon Petrochemical Co., Ltd., trade name: Shiraishi Neopolymer), nitrocellulose, cellulose acetate.

Polyamide, polystyrene resin, etc. can be used.

The binder can also be used in conventional thermal melt transfer recording V (such as carnauba wax, oxidized wax, etc.).
For hot-melt products using paraffin wax, Nisdel wax, etc., with a melting point of about 6Q to 90°C, the coloring agent is not limited to pigments, but may also be dyes or a mixture of 1 and 1, as required. The binder may contain softeners and other additives.

The substrate on which the recording material is coated should have a thickness of 3.5 to 167 mm, taking into account misalignment during thermal melt transfer and mechanical strength.
Heat-resistant substrates such as No. 1-shaped substrates such as m J'J', glass film, cellulose fiber paper and plastic fiber paper, or roll-shaped endless structure substrates with both ends of these notebooks connected are used. .

The conditions required for these substrates are that they have good conduction permeability to incident energy such as heat, radiation, and energy, and that they have a high melting point that is at least higher than the monthly recording vorticity. , when the solvent material is in a liquid state, it is not dissolved significantly, or preferably not at all, in the solvent material, and the recording material that has been thermally dissolved by the solvent material is easily transferred to a recording medium such as recording paper. As long as these conditions are satisfied, the substrate material can be freely selected, and it does not matter whether it is non-porous or porous.

Considering these conditions, capacitor paper, glassine paper, or polyester (PET) is usually used.

Films such as polyimide and cellophane are used.

Record printing is applied to a substrate by using an appropriate solvent to form so-called liquid ink, or by using a hot melt phase material as a binder, which is heated and melted and mixed, and then a sheet-shaped transfer material is created. ≠ done.

In this case, when the transfer material is used for multiple transfer recordings, the recording material is coated and impregnated onto a porous N-1-shaped substrate, or a lt7/L-shaped substrate with only the surface made porous. You can force it.

In fact, if you want to make the transfer medium disposable, apply the recording material to the notebook-like base in advance using an IJ/Komono.
When the substrate is made into a roll-like endless structure, the above-mentioned recording material can be reapplied to the surface of the used substrate prior to hot melt transfer recording, and the substrate can be used repeatedly.

In addition, by coating or laminating another synthetic resin on the surface of the substrate on which the recording month is applied and installed, it is possible to improve the adhesive strength of the recording month to the substrate surface or the heat-resistant solubility of the substrate against solvent monthly rate. .

In addition, in order to improve the adhesive strength of the recording material, expand the contact area of each recording month that affects the monthly solvent yield, and improve the thermal melting properties, for example, corona treatment may be applied to the surface of the film l-shaped substrate, or A rough surface having fine irregularities (for example, depth of about 1 to 5 μm) can be formed on the surface of the base film by a sandblasting method or the like.

1. To prevent the natural peeling of the recorded monthly rate from the substrate surface, mix other binders that do not dissolve in the solvent material and have excellent adhesion to the substrate surface, or add a binder to the recorded monthly rate surface. Fine irregularities (e.g. 1 to 5/14: '1j degrees) (
=J- In order to improve the heat-dissolving properties by increasing the solvent yield by 7:1, in addition to a heat-soluble binder, a second binder that is incompatible with this binder is added in a solution state. It is possible to mix/stiff and solid powder.

Such roughening of the substrate surface and the recording surface increases the contact area of each recording material with the solvent material, and at the same time, the solvent material is accommodated in a liquid state in the unevenness of the surface of each recording material. The amount of thermal dissolution is increased, and the transfer recording density can be significantly improved.

The amount adhered to the transfer material for each recording month is determined by the thickness (%V) (2) It is important to select V in a dry state, for example, from 1 to 157n++.If this thickness is too small, the recording medium will Recording density cannot be achieved due to insufficient amount of colorant transferred by thermal melting.
If the thickness is too thick, the temperature rise with respect to the incident energy is inefficient, and transfer recording of the recording material may become difficult due to insufficient thermal melting group.

For multi-gradation recording, full-color recording, etc., JfI vortex d1f1 degree V (correspondingly, the recording month can be faithfully transferred by hot melt transfer).
1 degree, but for these purposes, record May month C
1 dye sting alone type or both dye and binder are liquid 7j4
Dye-binder type ifL record 4 dissolved in the solvent of j
Al'1 may also be used. In addition, when weather resistance or bleed resistance is required, a pigment-binder type or a dye/pigment mixture-=binder type recording monthly rate structure is recommended.

The configuration described in ``2'' can be similarly applied to the case of using thermal melt transfer recording and thermal melt transfer recording in which a binder is stored in a reservoir under temperature increase writing control using incident energy.

Coloring agent - Binoda type recording material composition - C1 coloring agent / Koru dyeing agent;] - The mixing weight ratio of pigment and binder is preferably within the range of 1:50 to 1 = 1 (colorant: binder). selected. Too little colorant will cause the recorded reflection density to be too low, and too much colorant will lead to insufficient gloss of the recorded image and deterioration in weather resistance due to the lack of binder.

As the recording medium, plastic filter, ordinary recording paper, printing paper, or the like can be used, without necessarily having to use particles, as long as the recording medium is not significantly dissolved by the liquid solvent material. When the recording medium is made of paper, either Fn paper or Co-1 paper can be selected as appropriate.

The solvent is applied to, or impregnated with, one or both of the surfaces of the recording material or the surface of the transfer body onto which the recording material can be thermally melted and transferred.

The conditions required for the solvent are that the recording surface be in a fluid state under the rising temperature caused by the incident energy, and the composition of one or more species constituting the recording material.
[1] It has a positive thermal solubility iQ'i' property in which its solubility increases with increasing temperature. In this case, if the solvent material boils due to the temperature increase due to the recording rate, the quality of the transferred recorded image may be significantly reduced. It is recommended that the boiling point be chosen to be higher than the highest temperature rise on the record surface.

On the other hand, if transfer recording by thermal melting of the recording material is also used, the boiling point of the solvent should be set lower than the melting point of the binder, that is, the thermal melting transfer temperature of the recording material, so that the heat of vaporization of the solvent does not interfere with thermal melting. You need to choose high.

As described above, the solvent monthly rate can be selected as appropriate depending on the relationship with the binder material and dye that constitute the recorded monthly rate, whether it is a single material or a mixed monthly rate of a plurality of materials, regardless of whether it is aqueous or non-aqueous.

The melting point can be appropriately selected within a range that has a maximum value of the lowest surface temperature of the recording material when selectively 1-temperature writing is controlled by incident energy. Therefore, as long as this condition is satisfied, in principle, the temperature should be at room temperature (for example, about 0°C to 35°C).
Hot melt materials such as solid waxes such as solid paraffin, carnauba wax, oxidized wax, ester wax, and petroleum resin, and organic resins can also be used.

However, when thermal melt transfer is also used, the melting point of the solvent material is selected to be lower than the melting point of the binder of the recording material 4A, that is, the thermal melt transfer temperature.

For the second class of solvents, it is convenient to use materials that are liquid at room temperature (for example, about 0° C. to 36° C.) in terms of recording phase materials, ease of application to recording media, thermal solubility, and the like.

Even if the solvent material is solid at room temperature, it is desirable that it be transparent in order to prevent color change in the transferred recorded image, but it evaporates or emits at room temperature.
If it is A-1, it does not necessarily have to be colorless.

When the solvent material is liquid at room temperature, if its vapor pressure is too high, its evaporation will cause the transfer material to be removed from the transfer body and the recording medium through thermal melt transfer from the coating process 4' to the time period at the Nf process size. becomes too small, and the control becomes 1f. -force,
If the vapor pressure is too low, the recording medium on which thermal melt transfer recording is performed will not dry at all, resulting in a decrease in the resolution of the recorded image or causing stickiness.

Therefore, taking these into consideration, the atmospheric pressure of the solvent material (y e o
It is desirable to select the boiling point under (mmHq), for example, from a minimum of 60°C to a maximum of about 250°C, preferably within the range of 9Q to 200°C. Of course, as described above, the minimum value of the boiling point is selected to be higher than the melting temperature when the thermal melting property is also utilized.

The remaining solvent 4 is removed from the recording medium subjected to thermal melt transfer recording.
．． (If necessary, heat f+ at an appropriate temperature from at least one or both sides of the front side or back side of the recording medium, or evaporate it by blowing air.) This is a recommended method for preservation purposes and to prevent smudging of transcribed records due to the spread of thorns.

The solvent is solid at room temperature (e.g. 0°C to 35°C) or at low operating temperature (e.g. 0°C or less), and the recording material and surface of the recording medium are When used as a coating or impregnated, this solvent material can be used for temperature control beyond its melting point within a range that does not significantly heat-dissolve the recording material in the non-heated area during temperature-elevated writing control. It is applied in a liquid state by a heated roller or the like, and in a state where the means for maintaining this molten liquid state is set (=1r5), temperature-raising recording, thermal melting transfer and 11v, and peeling of the subject and the recording medium are performed.

When using the monthly solid rate at room temperature as the solvent month i1,
Unlike the case of using room-temperature liquid monthly rates, it is possible to use a recording medium in which a solid solvent material is pre-coated on the surface of the recording medium, which is considered a kind of dry method in terms of recording operation, and has a very good gloss. This is a recommended method because a certain transfer record can be made on Ordinary J11 paper.

However, care must be taken when applying or impregnating a hot melt or solution of a solvent material onto one surface of the record) l'Af, as this application or impregnation process dissolves the recorded monthly interest rate and tends to cause so-called fog transfer recording. It is. Therefore, in order to prevent this, it is convenient to apply or impregnate the recording medium.

Recording 4A The material is coated or impregnated onto the surface of the recording medium or recording medium in advance and stored, and the transfer body or recording medium is used as necessary.

The melting point of such solid solvent materials can be controlled by heating write control,
That is, it is determined by considering the incident energy supply means that participates in temperature increase recording control. When the incident energy is radiant energy such as infrared rays or laser beam energy, the temperature of the transfer body t' is controlled by a non-contact method.
The melting point C is selected to be simply room temperature or higher, for example 40°C or higher.
I'll do it.

However, when adopting a method of recording on the temperature rising side 1i111 by contact method using a known thermal recording head having a heat generating resistor element, the temperature limit should be set in consideration of the thermal rating of the recording head. determined. .

In a known thermal recording head, various semiconductor elements such as a latch circuit and a driver are mounted, and the upper limit rated temperature of the main body is, for example, about 80V.

Therefore, the melting point of the solid solvent material is selected to be at least below this upper limit rated temperature of 80°C. However, a maximum recording signal power of 1 W per single element is usually applied to the heating resistive element, and the temperature of the resistive heating element momentarily rises to 300 DEG C. or more. This electric power causes a temperature rise in the recording head body of about 20 DEG C. using conventional thermal diffusion cooling dimensions. Therefore, the temperature of the recording head body during continuous operation is up to 60°C when not recording.
It is necessary to keep it to a certain extent. The solvent material, which is solid at room temperature, must already be in a molten state at this temperature.

Therefore, the melting point of solid solvent I2 is 35°C to 60°C, considering that it is solid at room temperature (for example, 35°C maximum).
The recommended range is within the range of ℃, preferably 45℃ to 55℃.Of course, even in these cases, thermal melt transfer,
When also used together, the melting point of the cL1 solid solvent material is selected to be lower than the melt transfer temperature of the recording material (for example, about 60° C. to 90° C.).

In general, the temperature of the solvent material, including this temperature range, is
Temperature control is important because it directly affects dissolved transfer concentration.

Such temperature control of the solvent material can be carried out by, for example, bringing a temperature control roller into contact with the back side of the recording medium or the surface facing the recording material, or by using a round recording head. To do this, the temperature of the recording head body is controlled, or the temperature of the solvent material in contact with the recording head is controlled via the transfer body using the temperature of the recording head body, or the recording medium is brought into pressure contact with the surface of the recording head. It is possible to control the temperature of a recording platen made of metal, rubber, or a combination of these materials, or by appropriately combining one or more of these materials. The method of controlling the temperature of a solid or liquid solvent material at room temperature is the easiest and most recommended method in terms of equipment configuration.

As mentioned above, if the melting point of the solid solvent material is selected to be as low as 45°C to 55°C in order to use a thermal recording head, bleeding of recorded images or sticking of the recording medium may occur during long-term storage. . .

To solve this problem, a linear or strip-like heating resistor element is provided on the surface of the recording medium opposite to the resistive heating element array of the thermal recording head and opposite to the transfer body, and is synchronized with the main scanning recording signal. By heating the solvent material intermittently or continuously, the heating area is limited, so the effect of this heating on the entire recording head is reduced, and the melting point of the solvent can be lowered to 60%. ℃ or more”
− You can choose as high as possible. In this case, it goes without saying that the melting temperature of the recording monthly rate is selected higher than this, that thermal melt transfer recording is the main method, and that the melting point of the solvent material is selected lower than the heating temperature of the resistance heating element of the recording head. At this melting point temperature, the thermal dissolution characteristics of the recording material 1 are appropriately selected so that the amount of thermal dissolution of the solvent material in the non-heated part of the recording material does not cause fog transfer recording, or the thermal dissolution characteristics of the recording material 1 are appropriately selected, or the amount of thermal dissolution of the solvent material in the non-heated part of the recording material is At least one consideration is given to selecting a short time from when the solvent phase 14 comes into contact with the recording material until the step of separating the recording medium and the transfer body.

(hereinafter referred to as 欽b) The conditions to be kept in mind are summarized as follows. to L
In either or both of the heated and uncooled states, contact with the recording material or pressure contact state via the transfer body surface is provided.

(b) In case 1, the solvent material is coated or impregnated in advance on either or both of the recording material or the surface of the recording medium facing the monthly recording surface, or is coated or impregnated with the solvent material during the recording process of the present invention. Impregnated.

Therefore, when the solvent material is located only on the recording medium side, the solvent material contacts or impregnates the recording material from the recording medium side only by contact or pressure contact between the recording medium and the recording material H (i.e., the transfer body). .

Coating or impregnating the recording medium with different solvent phases d1: If the recording medium is non-porous, the solvent material is applied to the surface of the recording medium located on the recording material side; however, if the recording medium is porous; In this case, it is possible to impregnate the recording medium with the recording solvent by applying it not only to the recording material side but also to the opposite side thereof and allowing it to penetrate into the recording material side.

(c) The recording material surface of the transfer body is in contact with the recording medium surface for a period necessary for the recording monthly rate heated and melted by the above-mentioned (a) Odor-C solvent material to be transferred and recorded on the recording medium surface. Or, after the pressure contact state is maintained, the recording medium and the transfer body are separated.

(d) Peeling ray between the recording medium and the transfer body in the non-heating part during the selective heating process using incident energy, t, 4
During this period, the amount of solvent used should be taken into account on a monthly basis to ensure that the recording material does not dissolve and be transferred to the recording medium, or at least to the extent that one transfer company can ignore it compared to the temperature rising section. Subject to process constraints.

Without this restriction, the recording material is transferred to the recording medium even in the non-heated portion, causing so-called fog, which deteriorates the quality of the recorded image.

In order to prevent this, the solvent material should be selected so that the solubility of the recording material in the solvent material at the temperature of the non-heated part is extremely low or zero. Alternatively, in terms of the process, during the period 1 in which the separation process of the recording medium and the transfer body is completed from the contact of the solvent phase to the recording material, the amount of the recording material dissolved in the solvent material impairs the quality of the recorded image. 4-! The entire dissolution transfer recording process is completed in a short period of less than , j degrees. The peeling process includes paper peeling and recording phase f! "l
From the viewpoint of preventing peeling, it is desirable that the treatment be carried out during a period in which the solvent material does not lose its liquid state or fluidity.

The recording method and recording device according to the present invention provide (a)
The conditions of (d) to (d) may be included and may be combined as appropriate.

Among these various process combinations, the following points should be kept in mind in order to prevent fog transfer in non-heated areas and to obtain good recorded images.

When the solvent material is solid at room temperature, emphasis is placed on preventing fogging caused by dissolution of the 4N material, which is subject to temperature changes during the coating process or during storage.
It is recommended to coat or impregnate the recording medium rather than the surface of the recording material.

Coating with a solvent phase that is liquid at room temperature This should be done immediately before the temperature raising step so that the interval is as small as possible.

In particular, in order to prevent fog transfer and to perform good transfer recording of recorded images, it is desirable to apply or impregnate the solvent material only on the recording medium. This coating and impregnation step may be performed immediately before or even prior to the temperature raising step, as long as the solvent material does not evaporate unnecessarily, and is a recommended method.

In any of the above methods, the contacting and pressure-welding process between the recording material surface and the recording medium is performed within the time range in which the recording material surface is brought into contact with the solvent phase material as required and immediately before the moon temperature control]. This contact and pressure welding process can be continued through a temperature increase control process and up to the above-mentioned peeling process.

During this contact and pressure contact step, the above-mentioned thermal melt transfer of the recording material onto the surface of the recording medium and further thermal melt transfer recording are performed.

In the recording method and recording apparatus according to the present invention, for uniform thermal melting transfer recording onto a recording medium such as recording paper or plastic sheet, it is necessary to bring a solvent material into contact with the recording material and heat melt it. , it is necessary to maintain contact or pressure for the required time constant.

From this point of view, it is possible to perform temperature increase writing control using incident energy in image sequential manner on the transfer body which is held under one pressure by the recording medium via the m-medium old material, or to For example, in the vertical direction (i.e., in the main scanning direction), it is possible to control the recording material by scanning and increasing the temperature of the recording material using IC incident energy, or by controlling the temperature of the recording material according to the width of the surface of the transfer member. It is preferable to arrange a plurality of recording head elements across the width and control each element by time division or parallel line sequential scanning and temperature increase writing.

In the above, the transfer body and the recording medium can be moved at the same speed in the sub-scanning direction, even if they are moved intermittently or continuously in synchronization with the scanning temperature increase writing control cycle in the main scanning direction using incident energy. You may move.

The recording medium may be non-porous or porous, such as a plastic film or recording paper.

However, in order to perform high-sensitivity and good gradation recording by thermal dissolution, the amount of solvent material that can be located between the recording phase material and the recording medium or that can come into contact with the recording material, the recording medium containing the 1/ζ solvent material. It is necessary to consider the overall heat capacity and specific heat of the

For example, when the amount of solvent 4J and fil 1 stone is small, the absolute value of the amount of recording material that can be thermally decomposed is small at low temperatures, and when thermal melt transfer is used in combination, high density transfer is achieved at high temperatures, so the recording characteristics shift to the high temperature side. transfer recording characteristics with narrow latitude and high gamma value.

On the other hand, if the solvent is properly used, the recording material will thermally melt according to the temperature even in the low temperature range, increasing its ultimate absorption. The latitude is wide over the range, and good gradation recording characteristics with low gamma can be obtained.

However, if the solvent phase material is too large, the overall heat capacity including the recording medium will become excessive. As a result, it becomes difficult to raise the temperature of the solvent material by temperature recording control, and the amount of dissolution becomes insufficient.Although the latitude is wide and gamma is low, high density transfer recording results in a peeling distance of 51 feet.

The following methods are effective for these improvements. When the recording medium is non-porous such as a plastic film, the film surface is coated with a density finer than the recording dot density (usually 4 to 16 dots/parrot) and a depth of, for example, 1 to 1 by sandblasting or embossing. A fine unevenness of about 10 μm is provided, or a mud coat treatment is applied to the film surface by mixing calcium carbonate powder, etc., so that the film has the effect of securing solvent A and A.

On the other hand, when the recording medium uses a porous ink film such as recording paper, the solvent material may be impregnated excessively, or the recording material that has been heated and melted may penetrate deep into the recording paper, reducing the transfer recording density. Furthermore, in order to prevent melting, ;lit II, and heat-melting recording materials from permeating to the back side, starch, polyvinyl alcohol resin, etc. are coated on the back side of the recording medium to substantially prevent it. Either make the old material impermeable to the solvent, or coat the back side of the recording medium with a fluororesin, fluorine-based surfactant, etc. as a permeation-preventing agent, or apply and impregnate the old material with gold coating (so-called oil barrier). Prevents the transmission of another,
It is preferable to adjust the amount of impregnation and the depth of impregnation.

These recording media can be applied to either solvent-compatible coating or impregnation in a liquid state at room temperature or a solid state at room temperature, and are effective methods.

In the recording method and recording apparatus according to the present invention, by changing the color of the recording material on the transfer body, it is possible to transfer and record images of different colors using one or more recording heads.

By sequentially overlapping recording materials of different colors, multicolor recording is possible.

In this case, the colors are cyan, magenta, and yellow,
Furthermore, full-color image recording can be performed by using four primary colors including black and sequentially transferring and recording them using one or more recording heads.

These recording materials of different colors can be placed periodically on the same sheet-like transfer body, or on a so-called endless roll-like transfer body with both ends of a No. 1-like transfer body tied together. may be periodically applied to predetermined positions.

In these cases, faithful color reproduction requires thermal melt transfer of recording elements of precisely different primary colors at predetermined positions.

This effective means includes transferring and recording a marker on the edge of the recording medium in response to a recording signal voltage during the step of sequentially thermally melting transferring the first color s+211 old material onto the recording medium,
Thermal melt transfer of the second and subsequent color recording materials is facilitated by providing a means for photoelectrically detecting this marker and controlling the detection and correction of the required position to be heat melt transferred using this electrical signal. It can be achieved.

Below, regarding the recording method and recording device according to the present invention,
A specific example based on the above configuration will be described with reference to the drawings.

FIG. 1 is a cross-sectional structure of an embodiment of the recording method and recording apparatus according to the present invention, and shows the principle thereof.

In the figure, reference numeral 100 denotes a transfer body in which a colored layered recording material 120 is coated on the surface of a sheet-like base 110, and a recording medium 300 is pressed onto this through a liquid solvent old material 2o○.

Reference numeral 401 denotes an incident energy generator for generating and controlling incident energy 411 for selectively heating and controlling the recording material and also the solvent material through the substrate 110 by using a thermal recording head device, a carbon dioxide laser device, thermal conduction, radiant energy, etc. It is a control device.

This figure illustrates the temperature raising writing process using incident energy 411.

FIG. 2 shows an example of the solubility curve for the solvent material in the liquid state of the components of the recording 4m material in the recording method and recording apparatus according to the present invention.

In the figure, the horizontal axis represents the temperature 'r1 of one component of the recording material 120 and the liquid solvent phase material XO in contact therewith, and the vertical axis represents the saturation solubility of the recording material in the liquid solvent material.

In the present invention, the materials are selected so that the solubility S increases with respect to the temperature T as shown in the characteristics a, b, and c in the figure.

Therefore, in FIG. 1, in the part where the incident energy 411 is added, the old recording material 120
and a liquid solvent material 200 in contact with the recording material surface 121.
The recording material 120 itself or its constituent parts are thermally melted in accordance with this temperature.
A hot melt recording material 130 having a transfer recording function in the form of a solution or suspension is formed. The amount of hot melt recording material 130 is an increasing function of the intensity of the incident energy 411 or its pulse width.

Therefore, when the recording medium 300 that has been pressed under pressure is peeled off from the transfer body 100 while the solvent phase material 200 is in a liquid state,
The old recording material 130 in 1111 colors is transferred and recorded on the recording medium surface 301 at a density corresponding to the intensity or pulse width of the incident energy 411.

In this case, if the solubility curve of characteristic a in Figure 2 is dull < linear, the gamma value is close to 1, and if the solubility curve is super linear as in characteristic a, the gamma value is 1. On the other hand, when a sublinear solubility curve is shown as in characteristic C, the gamma value is smaller than 1, and either characteristic can be obtained by selecting a material of 120° or 200°, and conventional thermal melting can be used. Unlike the conventional transfer recording method, continuous gradation recording can be performed.

It should be noted that i? When the temperature of the recording material surface 121 and the liquid solvent 200 in contact with it is °r0, FIG. 2 shows /
J Tezuyo Koku Saturation Solubility S. If the temperature is large, the recording material 120 will be melted and transferred to the recording medium surface 301, albeit at a low concentration, even if it is in a non-thermal zone, resulting in so-called fogging.
will occur. To prevent this fog transfer, solubility S is used.

Either select a material for 4J 120.200 so that the amount is extremely small or zero, or bring liquid solvent 4JII 200 into contact with the recording material surface 121, and then reduce the incident energy 411.
The period until the recording medium 300 is peeled off from the transfer member 100 through the selective temperature increase control step can be selected to be shorter than the time required to reach solubility in order to deal with the troublesome fog transfer.

[Configuration example 1] For example, recording phase 120 is magenta and cyan.

Add 20 parts by weight of pigment as a coloring agent such as yellow or black, 2 parts by weight of carnauba wax or Nisdel wax as a binder agent, and about 20 parts by weight of oil and other additives as a softener, and the melting temperature is approximately 70°C layer thickness is approx. 4
In the case of a so-called normal phase-honodo melt binder type recording medium for heat-melt transfer recording of μ, the solvent material 200 is trichlorethylene (boiling point 87°C, melting point -86°C) or xylene/
(boiling point 138-144 °C), temperature T = 2
7'C, the contact time with the recording material 120 is less than 2 seconds, and it hardly dissolves and fog transfer does not occur.

Effective thermal melt transfer recording begins at T>40°C.

[Configuration Example 2] In addition, as the recording material 120, the colorants are, for example,
Xanthene C,1,5olvent Red49,

, when a black dye-binder type is used, a liquid medium material 20 made of, for example, liquid polyethylene glycol (for example, polyethylene glycol #2oO manufactured by Kanto Kagaku Co., Ltd.) is used.
When the temperature is 27° C. and the contact time is 2 seconds, almost no melting occurs and fog transfer can be prevented, and when the temperature rises above 60° C., high-density thermal melting transfer can be performed.

[Configuration Example 3] In addition, the binder material is, for example, a nitrocellulose type, and 14 to 20% by weight of pigment is added thereto, and the pigment-binder type gravure printing colored ink (for example, Narita Shokai's NA-N3 for G cellophane
70 (magenta color).

NA-Nsoo (cyan color), NA-N2e (yellow color), and NA-N1000 (black) have a monthly solvent yield of 200 at a layer thickness of 2 to 10 μm. For example, cyclohexano 7 (
Boiling point 155'C, melting point -45 (), room temperature 27C, 2
For seconds of contact, fog transfer is a negligible amount of dissolution;
At temperatures above 60 to 70°C, high-density thermal melt transfer can be performed corresponding to that temperature.

[Configuration Example 4] The binder material is, for example, oxide wax, for example, polyethylene glycol having an average molecular weight of 19,000 (softening point of about 63'C) (for example, Nihon Yushi Kogyo Co., Ltd. (7) PEGI).
#20000), magenta and cyan.

When the recording material 120 containing 14 to 20% by weight of yellow and black pigments is water as the solvent, it hardly dissolves and fog transfer does not occur at room temperature of 27° C. with a contact time of 2 seconds. First, hot melt IW transfer can be performed at 45°C or higher.

[Configuration Example 5] The binder material is, for example, an aliphatic hydrocarbon resin with an average molecular weight of 1200° and a softening point of 100°C (for example, Mitsui Petrochemical's Hiresotsu G-1ooX), and magenta, cyan, yellow, and black pigments, respectively. The recording material 120 mixed with 14 to 20% by weight is solid at room temperature and has a melting point of 44 to 4, for example.
When solid paraffin is used as a total solvent material of 200% at 6°C, solid paraffin liquefies 50" (:), which hardly dissolves with a contact time of 2 seconds, and thermal melt transfer recording occurs at temperatures above 70°C. The binder material may be solid paraffin with a melting point higher than that of the solvent material 200, such as solid paraffin with a melting point of 66 to 70°C, or microcrystalline wax with a high softening point (for example, Nippon Seirosha's Hi-Mic-Fuo 2095 (softening point 96)). ℃) or x'
7Soft Oil Company's Esmac + 180 (softening point 84℃)
), hot melt transfer recording can be performed in a state in which solid paraffin, which is the solvent material 200, is liquefied.

(＞・Susenfune mortar) These recording materials 120 have a thickness of 3.57j to 167m
Polyethylene terephthalate (PFT) of about 100% cellophane, a heat-resistant transparent film such as biaxially oriented polyvinyl alcohol, or a heat-resistant semi-transparent paper such as capacitor paper or glassine paper is coated and layered.

Thus, in FIG. 1, the transfer body 100. Recording medium 30

The above-mentioned fog transfer is performed by optically arranging the laser beams in a non-contact manner in a linear manner and performing non-contact focusing scanning, or by performing non-contact scanning with an infrared laser beam such as a carbon dioxide laser beam via a polygon mirror or an electrical element. Recording material 120 and solvent monthly rate 200 in order within the time it takes

0 contact and when these peelings are completed,
Characters, figures, and gradation images are recorded on the recording medium surface 301 at a transfer recording density corresponding to the increased temperature of the material 200.120.

Alternatively, in the above, while moving the transfer body 100 and the recording medium 300 in the same direction and at the same speed, a solvent is applied to either or both of the substrate surface 112 or the recording medium surface 301.
Immediately thereafter, the transfer body 100 and the recording medium 300 are brought into pressure contact, and the incident energy 411 consisting of the above-mentioned thermal conduction or radiant energy is applied in a line-sequential or beam-scanning manner in a direction perpendicular to the direction in which they move. Before temperature raising writing is controlled and fog transfer occurs, the transfer body 1 is
00 and the recording medium 300 are separated, I! i! Characters, figures, and gradation images can be sequentially recorded by thermal melt transfer.

Since the recording method and recording apparatus according to the present invention are based on hot melt transfer recording, the recording material 120 and the solvent monthly rate 2
It is only necessary to be able to control the temperature rise of the contact interface of 00, and thermal melting transfer can be performed in response to the temperature rise.As with the conventional thermal melting recording method, the image is transferred only after the heat of fusion is supplied by the incident energy 411. essentially different from that.

Therefore, as long as it is possible to control the incident energy generator 401, as illustrated in FIG.
Even if the recording medium 300 is installed on the back side 1111 of the recording medium 300 as shown in FIG. The material f4130 can be transferred and recorded on the recording medium surface 301.

For example, in the figure, when the recording medium 3o○ is a translucent plastic film, the incident energy 412 can be thermally melted and transferred by light energy in the same way as the incident energy 411 described above, and it can be transferred to a slide film or an overhead projector. - You can easily create film manuscripts, etc. ! jf: In the case of a heat-resistant translucent or opaque plastic film or recording paper, contact heat recording can be performed on the back surface of the recording medium using a thermal recording head.

The recording material 120 and the solvent material 200 are as described above [Configuration Example 1]
There is a follower C.

A capacitor paper with a thickness of 13 μm is used as the base 110, and a carnauba wax-colored pigment-based material 12 is coated on the surface of the capacitor paper.

Pressure welding is carried out with a pressure of 9130 g. This also has the role of adjusting the deformation of the rubber platen 500 due to the ρ pressure or the contact between the solvent material 200 and the recording material 120.Temperature rising recording is performed line-sequentially, and the main recording linear velocity is -.

The paper is intermittently fed by the rotation 501 at a sub-scanning density of 4 lines/mm. For temperature rise recording, each III antibody element was applied with a voltage of 13.35 V, a current of 62 V, and 4 niA (power of 0.

Using a sponge-like roller with a diameter of 10 Tnm, the recording solvent Coke 600 is moved as shown by the arrow 602 to contact the recording paper surface 301 with a circumferential length of about 36 mm from the recording section 410 of the head 403, thereby removing the solvent. -1200 is applied and impregnated.

The room temperature and the temperature of the recording solvent 200 during the experiment were 27'. Transfer recording density is reflective optical density 1 (Macbet
h RD 914) and was measured for each recording color.

FIG. 6 shows experimental characteristics when magenta colored transfer sheet 1-100 was used.

The characteristics are determined by the coater 6 as indicated by an arrow 601 in FIG.
00, and the solvent old material 200 is not applied to the recording paper surface 301, which is a known thermal melt transfer recording characteristic based on a so-called conventional method.

In FIG. 3, by applying the recording electric signal pulse from the C1 device 420, the temperature of each resistive heating element portion of the recording head 403 is increased to a maximum of 360' across the dot 1 corresponding to the nodal width PW. This thermal energy is thermally conducted from the back surface 111 of the reference notebook in the press-contact recording section 220 and transferred from the back surface 122 of the recording phase material 12 to about C.
Heat 0. Therefore, the recorded monthly interest rate 120 starts to be thermally melted from the back side 122 side in accordance with the pulse width Pw, but the front side 122
Transfer recording 140 does not occur until a certain pulse width PW that provides sufficient energy to thermally melt the second part is reached.

When this pulse width is reached, transfer recording 140 occurs discontinuously, exhibiting binary density recording characteristics in principle, and continuous gradation recording is difficult. In this example, this stable heat-melting transfer recording 1
40 is the rising pulse width PW-Pwrn:= 1-75
The coating thickness of the actual recording side separate layer 120 is uneven, and even when "W >"Wrn, the thicker portions are sequentially melted and transferred, the transferred recording density increases, and PW
:3, 6 mS shows a maximum recording density of 1.2.

On the other hand, the coater 600 is moved as shown by an arrow 602 to coat and impregnate the recording paper surface 301 with a solvent material 200 which is a liquid at room temperature. According to the present invention, the time from this coating to the time when the recording material layer 120 comes into contact with the recording material layer 120 to be recorded at an elevated temperature, and the recording paper 300 and the transfer notebook 10o are separated, and the solvent old material 200
Since the solubility is appropriately selected, the layer surface 121
However, when the temperature is not raised, the amount of dissolution is small, and the transfer density, that is, fog transfer is prevented.1 The characteristic Md is a characteristic obtained by the hot melt transfer recording method according to the present invention. In response to an increase in Pw and therefore an increase in the temperature of the layer surface 121, pressure welding! Since the solubility of the solvent material 120 in the one-temperature recording section 220, that is, the amount of the heat-dissolving recording material 130, increases continuously, the recording density transferred to the recording paper surface 301 increases.

rises continuously from

The rising pulse width is PW-PWd-o+9 ms, and there is no discontinuous point like the characteristic M1n, indicating that continuous tone transfer recording is possible. Boiling point of solvent material 200 (
87°C) is higher than the melting temperature (=70"C) of the recording material 120, in areas where PW is large, conventional transfer recording by thermal melting is also added, and a highly sensitive transfer record 140 can be obtained.

For example, the characteristic Mrn of the conventional method is P == PW, n-1
, 75 m s, D = 0.7, whereas with the characteristic Md of the present invention, D = 1.05f, a high concentration of -Co, 35 can be obtained compared to the conventional method.

The maximum concentration D of the characteristic Mm is 3.5 ms, whereas the pulse width Pw of the characteristic Mm is 3.5 ms. PW = 2,
5 ms, and its pulse width PwO ratio was 1/1.
4 shows that compared to the conventional method, 1.4 times faster line sequential recording can be performed while giving the same density, and the unnecessary power supply can be saved by about 30%. In general, it is said that the service life of a thermal recording head decreases in proportion to the -18th power to the 121st power as the supplied power increases. When considering the difficulty of improving the recording speed with the recording head configuration, it is obvious how great the effects of the present invention will be.

Thus, in the recording method and recording device according to the present invention,
Excellent effects such as continuous tone transfer recording, high density, and high speed recording, which were difficult with conventional thermal melt recording, are achieved by using solvent materials with 20%
This exposes the principle of the thermal melt transfer recording method, which performs selective temperature-rise transfer recording while zero is in a liquid state. It is clear that this method is fundamentally different from the conventional thermal melting recording method in which a very large amount of melting energy must be supplied in the thickness direction of the recording material layer using thermal conduction energy.

Figure 6 shows the same experimental method as in Figure 6 (Configuration example 1).
), (The thermal melt transfer recording characteristics according to the present invention when only the color of the colored pigment is changed to yellow, and the characteristic CD is cyan color and Yd is yellow color transfer sheet 100. The characteristics used are 3.1) Both Cd and Yd, similar to the characteristic Md in Figure 6, D
is the recording density. It can be seen that continuous tone thermal melt transfer recording can be performed. In addition, in the conventional melt transfer recording method in which the solvent material 200 is not applied and impregnated, the characteristic M shown in FIG.
Binary transcription record q similar to m! The stable transfer recording pulse width Pwm indicating i1 kuyu is 1.5 ms for the cyan color sheet.
The yellow color notebook is 1.75m5. It's 1.
The same applies to a black sheet in which the colored pigment is replaced with carbon powder, and the hot melt transfer recording method of the present invention exhibits continuous tone transfer recording characteristics, while the conventional melt transfer recording method exhibits binary transfer recording characteristics.

Note that since the solvent material 200 applied to the recording paper 300 in FIG. It is also possible to provide evaporative drying means (=1) such as low θ, 1'4, -/41°, or normal temperature air blowing.

In this way, the old recording materials 120 of magenta, cyan, yellow [''-1 and d-black, etc., described above are applied in a predetermined order in the length direction of the base sheet 1111, etc., in order.
Superimposed rotation on the recording paper surface 301'-! -1' When recording, in a state where the coater 600 moves as shown by the arrow 601, two-color transfer recording is performed using the conventional thermal melt transfer recording method, and the Ushida Coke 600 moves as shown by the arrow 602. And, of course, multi-color transfer recording,
Continuous gradation full color transfer recording is possible.

When using dyes as colorants in the above monochrome, multicolor, and full color hot melt transfer recording,
When the above-mentioned [Configuration Example 2] aims at odorless evaporation of the solvent material 200, the above-mentioned [t14 Example 4] is used, and when the solvent material 200 that is solid at room temperature is used, d2 and the above-mentioned [Configuration example 6] can be used. Further, when thermal melt transfer is not required, [Configuration Example 3] having a high softening point, which is difficult to perform thermal melt transfer recording with a normal thermal recording head, can be used.

In addition, in the case of use in a cold region, water, which is the solvent material 200, freezes in [Configuration Example 2], and in the case of [Configuration Example 5], the material 200 is solid at room temperature.

Therefore, in FIG. 3, a heating means such as a resistance heater 810 is installed in the solvent material container 700, and the solvent material 200 is heated.
The solvent material 200 is melted and liquefied, and coated and impregnated onto the recording paper surface 301 at a predetermined temperature via the coater 600. Furthermore, in order to keep this liquid solvent material 200 at the predetermined temperature as described above, a resistance heating heater 811 is used. A heating means such as the following is provided on the recording platen.

In the recording method according to the present invention, as described above, the temperature of the liquid solvent material 200 in contact with the non-f1 temperature area affects the amount of thermal dissolution due to temperature increase control writing as well as fog transfer.

Therefore, the installation of the heating and heat-retaining means 810, 811, etc. described above has the advantage that stable heat-melting transfer recording can be performed without being affected by the ambient temperature, even when using the solvent material 1F200, which is liquid at room temperature. As shown at 812 in the figure, before the temperature raising writing process, a heated cola may be brought into contact with the surface 121 of the recording material, or this roller may be brought into contact with the back surface 111 of the substrate.
By contacting the side, the surface 121 can be set at a predetermined temperature to stabilize the recording operation.

In the above embodiments, the solvent material 200 was applied and impregnated onto the recording medium surface 301, but it can also be applied onto the recording medium A stone surface 121, or applied onto and impregnated onto both the surface 301 and the surface 121. .

7A is a diagram showing another embodiment of the recording method and recording apparatus according to the present invention. This is an example of coating and impregnating 121. Solvent material to be applied 200
To determine the thickness (i.e. amount) of the solvent, a solvent amount control roller 610 such as a metal or rubber roller is provided, and when the coater 600 is a sponge body, the contact pressure and gap are controlled by the coater 600.
When the material is a non-porous material such as metal or rubber, the amount of coating on the recording medium surface 121 is adjusted by adjusting the gap.

The coating amount adjusting means such as the roller 610 can be similarly applied to the case of FIG. In this example, when a transfer sheet 100 for thermal melt transfer is used, the coater 800
If it is moved as indicated by an arrow 601, conventional heat-melting transfer recording will be performed, and if it is moved as indicated by an arrow 602, it will be a heat-melting transfer recording according to the present invention, and further Q:].

It is possible to perform recording using a combination of this and thermal melt transfer.

Although recording paper is used as the recording medium 300 in the following example, a porous recording medium can also be used in the same manner.

As described above, the solvent material 200 can be applied to either the recording medium surface 3o1 or the recording medium surface 121, and furthermore, this Ω-, iN! However, from the viewpoint of shortening the contact time of the liquid solvent material 200 with the recording material 120-5 and preventing fog transfer, it is convenient to apply and impregnate the recording medium surface 301.

8th. 9th. Figure 10 shows s+: &7 according to the present invention.

In heat-melting transfer recording, it is necessary to secure the necessary amount of liquid solvent material 200 sufficient to heat-dissolve the recording material 120 in the pressure-contact recording section 220, and to ensure more effective heat-melting, the recording material 120 and Consideration must be given to expanding the contact area with the liquid solvent material 200.

For example, if the recording medium 300 is made of a material with extremely good surface smoothness, such as a plastic film or art paper, and the base sheet 110 is made of a PET film or the like, and the recording medium surface 121 is in an extremely smooth state, the pressure recording unit 220 , the liquid recording solvent 200 is pushed out by the contact pressure, and the recording medium surface 301 and the recording material layer surface 201
The supply amount of the solvent material 200 located in between is insufficient. Therefore, at the heating temperature recorded in the low-temperature source, the thermal melting record

(v is thick) Move to jllll. When heat melting and heat melt transfer are used together, if the contact pressure is extremely high, the heat melt % will result in a record similar to that of copying.

To prevent this, for example, as shown in FIG.
On the surface 112 of a base film 1100 such as PET with a thickness of about 16 μrn, fine irregularities 113 with a depth of about 1 to 5 pm are formed on the surface 112 of the transfer record 140 within a range that does not significantly reduce the mechanical strength, considering its thickness. A transfer sheet (sheet) 100 is formed by sandblasting, corona treatment, chemical engineering, or coating with a density higher than that of the recording material 120 on the surface of which the recording material 120 is applied to a thickness of, for example, about 2 to 771 m. It is effective to use it.

In this way, unevenness 123 corresponding to the unevenness 113 is generated on the recording medium surface 121, and the liquid solvent material 200 is accommodated therein also in the press-contact recording section 220, and the solvent material 2
The amount of the solvent material 200 is ensured, and the contact area of the solvent material 200 with the recording material-1 and the solvent material 200 is expanded, thereby improving good thermal melt transfer recording characteristics.

(Ichiyori f3) Figure 9 shows that fine powder such as 191J, such as calcium carbonate, is coated on the surface of a heat-resistant non-porous substrate 110 such as PET film or capacitor paper. , or use a heat-resistant resin such as polyester resin as an underlayer to form a porous layer 1.
24, and this porous layer 124 is coated with and impregnated with a recording material 120.

If the thickness of the layer 124 is too thin, it will be difficult to obtain the transfer recording density power, and if it is too thick, the heat capacity will be too small, making it difficult to control the heating temperature and making it impossible to perform high-speed recording.
74711, and the overall thickness of the transfer A4 (100) is also selected to be within 30 lt m.

In this way, the recording phase part 120 is impregnated in a porous manner, and its surface 121 also has unevenness 123, so that the pressure recording part 220
Then, the liquid solvent material 120 is accommodated within the surface irregularities 123 and 1ψ 124, and effective thermal melt transfer can be performed.

Figure 1Q shows yet another configuration of the transfer body, using a heat-resistant porous paper such as Manila hemp or pulp with a thickness of 10 to 30 μm, and a recording material for the back side. In order to prevent the leakage of solvent and liquid solvent old material, surface J thermal leakage prevention agent 160. For example, heat-resistant resin such as polyester is coated and impregnated and calendered.
FC-721 etc.) and impregnate it. Recording material 12o
is applied and impregnated into the remaining porous area. The liquid solvent old material 2oo is accommodated in and brought into contact with the uneven portions and porous portions of the transfer body surface 121.

The sheet-like transfer body 1o0iJ shown in FIGS. 9 and 10 has the advantage that it can be used for hot melt transfer recording multiple times as long as the recording material 120 is present in the porous medium.

The necessary amount of the solvent paulownia material 200 in the press-contact recording section 220 can also be secured by placing it on the recording medium 300 side. For example, when a non-porous material such as a plastic film is used as the recording medium 300, the surface of the recording medium 300 is etched to a depth of about 1 to 571 m by chemical etching, sandblasting, coating, etc., as explained in FIG. It is advantageous to provide a coating with manotoko-1, such as calcium carbonate, or to perform a tar coating treatment in the same manner as explained in FIG. In this case, the restriction on cleanliness is less strict than in the case of FIG. 9, and for example, a coating containing fine powder such as calcium carbonate is applied to the surface within 20 7/m 2 .

Using porous paper as the recording medium 300 as in the embodiment shown in FIG. 3 is recommended from the viewpoint of maintaining 6'fL of the solvent material 200, and its smoothness is preferably about 600 to 200 seconds.

However, as in the example shown in FIG.
0 is coated or impregnated, etc. -C5 Porous recording paper generally has good liquid permeability, so solvent material 200
The recording platen 500 may be impregnated excessively, and furthermore, this may pass through and leak out to the back side of the recording platen 500, causing inconveniences such as smearing or adhesion of the recording platen 500. Such solvent 4; t 11200
Excessive storage of the recording medium 300 causes the heat capacity of the recording medium 300 to increase excessively, and the heat conduction and diffusion thereof also becomes excessive. t, 1 property is obtained (l Despite this, high temperature, 1: ink if;
High-density transfer ability; +jJ may become a non-light component, or thermal melting recording gain 130 may be diffused, resulting in a decrease in recording resolution.

To prevent this, as shown in the cross-sectional view in FIG. 11, the recording medium 300 is
The solvent material 200 is coated with and impregnated with starch, etc., and treated with supertalenda, or coated with an oil barrier such as fluoride 1 fat (for example, Fluorad FC-721, manufactured by 3M Co., Ltd.) to prevent the permeation of solvents insoluble in the solvent material 200. Preferably, a coating 310 is applied. In particular, the oil barrier treatment requires only a small amount of :d to be applied, which does not eliminate the porosity of the recording paper 300a, so the increase in heat capacity can be ignored. Suitable for recording.

As in the above-mentioned [Configuration Example 5], the solvent material 1') 200 is made of a room-temperature solid material such as solid paraffin, and the solvent material 11 and - are pre-coated on the surface of the non-porous recording medium 300 such as PET film. , or a composite type recording a that is coated and impregnated on the surface of the recording medium 300 with the porous fjj゛ of the recording paper q+7.
When an IL body is used, a simple thermal melting transfer recording device that is substantially dry at room temperature can be realized. The actual thickness of the solid solvent material 200 impregnated into the coating material 200 is determined by taking into account the degree of thermal dissolution with the recording phase material 120, but is usually calculated in terms of thickness. The amount is selected to be equal to or greater than the thickness of the recording material 120.

When the recording medium 300 is a porous material such as recording paper, the solid solvent material may be thermally melted/in this liquefied state during application or impregnation, and seep out to the back side, or hot melt transfer recording may occur. The recording material 140 may be transmitted to the back side,
This may cause inconveniences in terms of storage or transfer recording operations. To prevent this, as shown in FIG.
It is recommended to use a composite recording medium 320 in which the recording medium 300 shown in FIG. 11, which is made of a porous recording paper 300a coated with a solvent transport prevention coating 310, is coated and impregnated with a normal/lIM solid solvent material 200. be done.

Application and impregnation of the solvent material 200 to 300& can be easily carried out by raising the temperature above its melting point and using a liquefied state or a solution.

FIG. 13 is a diagram showing another embodiment of the recording method and recording apparatus according to the present invention.

This example uses the composite recording medium 320 described in FIG.
So-called heating control recording platen 610 with built-in 10 etc.
The solvent material 200, which is solid at room temperature, is heated and melted from the back surface 322 of the recording medium 320, and the recording material 120 is heated and melted at the recording pressure contact portion 220.

In order to prevent fog transfer, the heating melting temperature is selected to be slightly higher than the melting point of the solvent material 220. Note that when the recording w body 320 is thick or in cold regions, the surface portion 32
1 is insufficiently melted, the auxiliary heating roller 813
Improve this Jl- by installing a.

In addition, in order to prevent the solidification of the solvent material 200 and to ensure the necessary thermal dissolution time constant of the recording material 120 with respect to the liquid solvent material 200, an auxiliary roller 82o is provided, for example, as shown in the figure, in accordance with the time constant. The transfer 7-t 1 is transferred from the pressure recording section 220 by the thermal recording head 403.
00 and the composite recording/-to 3o○ to the peeling position can be selected as Takashima.

Thus, according to the present invention, as in the example of FIG. 3, wet melting t11. 'J nJ There is no need for troublesome coating, etc., and the recording device is virtually dry and has excellent operability.
A transfer record 140 in which the recording material 120 is thermally melted is obtained.

Note that a composite transfer body in which the surface of the recording material in the transfer body or the recording material is impregnated with the solvent material that is solid at room temperature can be used.

FIG. 14 collectively shows the cross-sectional structure of the composite transfer body. The composite transfer body 160 has all the structures of the transfer body 100 described above, such as the non-porous substrate described in FIG. 3, the non-porous substrate with the uneven surface shown in FIG. A room-temperature solid solvent material 200 such as solid paraffin is applied to the recording material surface 121 of the transfer body 100 in which the recording material 120 is coated and impregnated on the filtered substrate or the porous substrate 110 having the leakage prevention coating 160 shown in FIG. Construct by coating and impregnating.

Application and impregnation of solvent material Af-1200, for example, using a thermal coater selected slightly higher than this melting point, melted solvent material 200 is applied to the transfer body 100-1 (immediately after impregnation). Next, these are rapidly cooled to prevent fog transfer due to thermal dissolution of the recording material 2o○ onto the solvent hole 200.

The amount of the solvent material 200 to be applied is determined as appropriate in consideration of the thermal solubility of the recording phase material 120.

However, if the thickness of the composite transfer body 160 becomes too large,
Since thermal melting of the solvent material 200 becomes difficult, and in this process, the recording phase material 120 is thermally melted and fog transfer occurs, the thickness of the recording material 120 is 2 to 7 μm in terms of thickness, and the coating amount of the solid solvent material 200 is reduced. It is desirable to select the thickness to be approximately 1 to 7 times (2 to 4977111) times the thickness of the recording material.

FIG. 16 is a diagram showing another embodiment of the recording method and recording apparatus according to the present invention, and shows an example using a composite transfer body.

The composite transfer body 7-1-160 is pressed against the surface 301 of the sheet-like recording medium 300 by an auxiliary roller 821, and before it reaches the pressure-contact recording section 200, it is pressed by a heating control recording platen 610. The temperature controller 83 is used to prevent transfer due to thermal melting of the recording phase material 120, which has a high melting point, through the recording medium 300.
Heating at 0? 1jlJ is controlled and turned into a liquid state.

Note that when the old solvent material 200 is thick and cannot be easily thermally melted, the auxiliary roller 821 is used as a heating roller to heat the base 1.
Auxiliary heating can be performed from 10[1].

In this way, by selectively increasing the temperature writing control by the throat 403 in the thermal recording, the recording material 120 is thermally dissolved in the liquid solvent material 200 in the pressure recording unit 220 in response to the increased temperature, and this Heat-melt recording material 130 is transferred to recording medium 300 to produce transfer record 140 .

According to this method, the binder material in the recording material 120 tends to become the transfer recording 140 of the room-temperature evaporable bath medium phase material G. Since the hot-melt wax solvent SEI [200] is used, there is an advantage that a glossy transfer record 140 can be obtained.

FIG. 16 is a block diagram showing still another embodiment of the recording method and recording apparatus according to the present invention.

In this embodiment, cut paper is used as the recording medium 300, and yellow color 120Y is used as the size recording material 120.

Magenta color 120M and cyan color 120C are sequentially arranged side by side in a dangling pattern, and these recording materials 120Y, 12
0M, 12OC surface was coated with solvent 4J f4200 (solid at room temperature) and impregnated using composite transfer sheet 161.
This is an example of performing transfer recording of a full color image. 520 is a transfer paper roll 540 which is a transfer paper winding roll.

The cut recording paper 300 is separated from the heating control recording platen 530 that has a built-in heater mechanism 812 by moving the thermal recording head 4oa as shown by the arrow 421, and then moving the cut recording paper 300 to the platen 5.
In a state where the paper lock mechanism 531 on the paper feed table 550 is located at a position facing the paper feed table 550, the paper is fed from the paper feed table 550 via the paper feed roller 551, and its leading end is fixed by the lock mechanism 535. platen 53 as shown by arrow 532
The leading edge of the cut paper 300 is pressed against the recording unit 2 by 00 rotations.
20, point the head 403 at arrow 422
The yellow recording section 120Y of the composite transfer sheet 161 is pressed between the recording section 410 and the cut paper 300. Due to this pressure contact, the solid solvent material 200 on the transfer sheet 161 is melted and liquefied by heat conduction from the platen surface 531 through the cut paper 300.

In this state, when a yellow recording signal is applied line-sequentially to the head 403 from the driving power supply device 420, a yellow transfer recording 140Y is obtained line-sequentially by thermal melt transfer recording.

When the locking mechanism 535 approaches the pressure recording section 220, the head 403 is moved as shown by the arrow 421 and released, and the mechanism 535
When the head 403 passes the pressure recording unit 220, the head 403 is pressed again as shown by the arrow 422, and with the yellow transfer record 140Y in a predetermined position, a magenta recording signal is applied line-sequentially from the device 420 to the predetermined position. Perform magenta transfer recording 140M, and then cyan transfer -H1140C in the same manner.
After this is completed, move the head 403 in the direction of arrow 42.
1, and rotate the platen 530 in the opposite direction as shown by the arrow 533.
The paper is returned to the top and comes out.

On the recording medium 300 made of cut paper (/l= means rishi,
A glossy full-color image consisting of photo records 140Y, 140M, and 140C is recorded by hot melt transfer.

FIG. 17 is a cross-sectional schematic diagram of an example of a pond of a color composite transfer sheet.

The transfer sheet 162 is used by being fed as shown by the arrow, and the transfer recording order is hr), and the width and length correspond to the required recording image area. 120Y, Magentaki 8 + Shrinebetsu 120M
, cyan recording material 120C is coated regularly on the base sheet 110 in a band shape, and on the surface thereof,
A solvent absorbent 200 consisting of a colorless hot-melt material 4'-1 which is solid at room temperature is coated and impregnated.

Separation is provided between each primary color to ensure that there is no undesirable solvent material and dissolution transfer of the recording material to the recording medium. Between the last number and the first primary color recording material, in this example, 120C and 1
A colored strip marker 170 insoluble in the solvent material 200 is provided between 20M and is photoelectrically read and used as a cue signal during thermal melt transfer recording.

FIG. 18 is a cross-sectional structural diagram showing another example of the configuration of a composite type transfer notebook for color. What differs from FIG. 17 is that the yellow recording material is in the first order in the sheet feeding direction as shown by the arrow. A solvent material 200 that is solid at room temperature is located in 120Y, but the solvent material 200 is not applied to the magenta recording material 120M of the second rank.

In color recording, the same portion is transferred and recorded using different primary color recording materials. Therefore, when a solvent material is transferred and attached to a recording medium for each primary color, an excessive amount of the old solvent material overflows and sometimes reduces the image resolution of the recorded image. This method utilizes paulownia wood, a liquid solvent during thermal melt transfer of primary color recording materials.

In this example, the bath medium material sum is 1.200ii, and the Noan record of the third rank is also provided in the J material 12OC section. However, 200 yen of the solvent material was added to the 12 oz.
Although it is essential to provide 11,200 copies of the cyan recording material of the song, for example, the 11,200 copies of the cyan recording material ranked third in this example, it is possible to omit it if necessary.

Between each recording material 120Y, 120M, 12OC are solvent material 200-insoluble cue markers 171, 17 of different colors or patterns for the respective primary color recording materials.
2.degree. 173 are provided respectively, and these can be read photoelectrically to ensure accuracy in overlapping transfer recording.

FIG. 19 is a cross-sectional structural diagram of another configuration example of a color composite transfer sheet, which is a color recording old material 120Y.

120M and 120C, the solvent material 4J which is solid at room temperature is not provided, and a solvent material layer 200A which is solid at room temperature and has the same length and width as the color recording material is provided on the substrate surface 112 prior to the color recording material. 174 is a marker for photoelectrically detecting the solvent material layer 20OA, and 17Q is a marker for photoelectrically detecting the color recording material mentioned above. Configure.

In this transfer notebook 161, first, the solvent paulownia material 200A is melted and uniformly transferred to the recording medium (C).

Following this, 120Y, 120M, 120

According to this example, the solvent material is a color recording material of 120Y
, 120M, 120C should not be directly applied or impregnated, otherwise the old recording material will diffuse and dissolve while the sheet is being stored, causing fogging and
This will prevent you from copying Tom's pictures. This effect is particularly noticeable when dyes are used as colorants in recording materials.

In addition, a solvent that is solid at room temperature (original material can be installed in two or more of recording 4A materials 120Y, 12oht, and 120C depending on the center spacing).

In the transfer sheet described below, the order of the color recording materials 120Y, 120M, and 120C can be changed as appropriate, and a black recording material can be added to make four colors.

This is an example in which the four primary colors of No. 7'7120C and 120B recording materials are coated and impregnated in one center, but black 1
Any color is fine, except for 20B.

In the above-described recording method and recording apparatus, the primary color recording rates are sequentially superimposed on the recording medium and transferred to the hot melt M7'L. Therefore, VC, which reduces smearing in overlapping transfers and produces high-resolution color images, is recommended to use pigments rather than dyes as colorants because they do not dissolve and diffuse.

Although the foregoing explanation has been vaguely explained using a thermal recording head as an example, the above embodiments can be similarly applied to 51 monitoring and recording control using a laser beam or a light beam using a light emitting diode array. ! The descriptions of the 12 cases of fruit and the skin of this specification can be carried out in combination as appropriate.

Effects of the Invention As mentioned above, the present invention is a recording method and a recording device based on the principle of hot melt transfer recording, and realizes continuous tone transfer recording, which was impossible with the conventional hot melt transfer recording method. Not only that, but also high-density recording and high-speed recording have been realized, and the industrial effects thereof are extremely large.
