2. Description of the Related Art An offset printing method using a lithographic printing plate is a typical means for dividing a surface into a liquid adhesive area and a non-liquid adhesive area for use in image formation. However, in this offset printing method, it is inevitable that the apparatus becomes large in size by incorporating the plate making process from the original plate and the printing process from the printing (printing plate) into one device. For example, even in a relatively small-sized office offset plate making printing machine, in many cases, the plate making apparatus and the printing apparatus are separate.

In order to eliminate such a defect of the offset printing method, a liquid adhesive area and a non-liquid adhesive area can be formed according to image information, and can be repeatedly used (reversible Recording methods and devices have been proposed. Some of them are as follows. (1) Aqueous development method After a charge is applied to the hydrophobic photoconductor layer from the outside, it is exposed to form a pattern having a hydrophobic portion and a hydrophilic portion on the surface of the photoconductor layer, and only the hydrophilic portion is formed. Aqueous developer is attached and transferred to paper (Japanese Patent Publication No. 40-18992, Japanese Patent Publication No. 40-18993)
(Japanese Patent Publication No. Sho 44-9512, Japanese Patent Publication No. Sho 63-264392, etc.) (2) Method utilizing photochemical reaction of photochromic material A layer containing a material such as spiropyran and an azo dye is irradiated with ultraviolet rays to produce photochemistry. The reaction makes these photochromic compounds hydrophilic [eg, "Polymer Thesis Collection" Vol. 37, 4
No. 287 (1980)] (3) Method utilizing the action of internal biasing force An amorphous state and a crystalline state are formed by physical changes to form a liquid ink adhesion / non-adhesion region (JP-B-54). -4190
(Gazette No. 2).

According to the above method (1), after the water-based ink is transferred onto paper or the like, the hydrophilic portion is erased by static elimination, and another image information can be recorded. That is, one original plate (photoconductor) can be repeatedly used. However, since this method is based on the electrophotographic process, charging → exposure →
It requires a long process of development → transfer → static elimination, and has the drawbacks that it is difficult to downsize the device, reduce the cost, and make it maintenance-free. According to the method of (2), hydrophilicity and hydrophobicity can be freely and reversibly controlled by selectively changing the irradiation of ultraviolet rays and visible light, but the reaction time is very long because of poor quantum efficiency. However, it has drawbacks such as slow recording speed and lack of stability, and it is a fact that it has not yet reached a practical level. Further, according to the method of (3), the information recording member used there is stable after recording, but before recording, the physical structure may change due to temperature change. Therefore, there is a problem with storage stability. In addition to this, since a means for applying a heat pulse and then quenching is adopted for erasing the recorded information pattern, there is a disadvantage that repeated image formation cannot avoid complexity.

The present inventors have conducted research and studies for solving the conventional drawbacks and inconveniences. As a result, a specific recording medium (a recording medium having a surface whose receding contact angle decreases when in contact with a liquid in a heated state, for convenience, simply referred to as "recording medium" or "recording medium (A)") and Contact material
(Liquid, vapor or solid which becomes liquid or generates liquid or vapor at the temperature below the receding contact angle reduction start temperature referred to in recording medium (A)), and the surface of recording medium (A) as contact material (B) By selectively heating in the state of contact (this heating may be from the front side or the back side of the recording material (A)) or while the surface of the recording material (A) is being selectively heated. By contacting with the contact material (B), a latent image showing a receding contact angle according to the heating temperature is formed on the surface of the recording material (A), and the latent image is visualized with a recording agent containing a coloring material. Then, a method for transferring this visible image to a recording medium and an apparatus related thereto were proposed (Japanese Patent Laid-Open No. 3-178478).

According to the method proposed here, formation of a latent image and a visible image on a recording medium, transfer of the visible image to plain paper or the like (transferred substance), and erasing of the latent image are extremely performed. Since it can be easily and reversibly performed, not only can a large number of sheets be easily copied, but also different copied images can be continuously obtained. Margin below

[0007]

The outline of the proposed device and the like is as shown in FIG. Here, the recording body 21
The thermal head 22 serves as a heating means (heating source) for the surface.
Is used to perform latent image formation and development at the same time. In the figure, 23-1 is an ink (also serves as a contact material and a recording material), 2
3-2 is a plate for containing the ink 23-1, 24 is a transfer roller, 25 is recording paper, 26 is a cleaner, and 27 is an image removing lamp. In this apparatus, recording is performed according to a digital image signal, and at that time, a latent image is formed in a dot shape as shown by 28 in FIG. And the ink 23
-1 adheres to the latent image portion while peeling off on the recording body 21.
Next, the ink attached to the latent image portion is transferred onto the recording paper 25 by the transfer roller 24, and a desired image is formed on the recording paper 25.

Here, temporarily, when forming a surrounded pattern image on the recording paper 25, if the latent image is composed of continuous dots as shown by 28 in FIG. 8, the ink adhered to the latent image at the time of development. Since the passage is blocked, ink adheres to the non-latent image portion. FIG. 9A is a view showing the ink adhesion state to the non-latent image portion, as seen from the cross-sectional direction cc of the recording body 21. E in FIG. 9 is extra ink adhesion. If this is transferred to the recording paper 25, so-called crushed characters occur.

In the following description, an explanatory diagram regarding the state of the recording material (eg, ink) attached to the recording medium (FIGS. 1A and 1B)
(C), FIG. 3 (B), and FIG. 4 (A) (B)) are viewed from the cross-sectional direction of the recording medium.

An object of the present invention is to provide a recording apparatus which ensures the above-mentioned problem, that is, the independence of ink adhesion of latent image dots, and obtains a good transferred image on a recording paper.

[0011]

A first recording apparatus of the present invention is a recording medium (A) by selectively heating the surface of the following recording medium (A) in contact with the following contact member (B). A contact member (B) that forms a latent image showing a receding contact angle corresponding to the heating temperature on the surface of the recording body (A) by bringing the surface of (A) into contact with the contact member (B) while being selectively heated. ) The recording body
(A) a means for supplying to the surface, a means for selectively heating the surface of the recording material (A) according to an image signal to form a latent image, a developing means for moderating the latent image, and a recording material (A ) A recording device provided with a means for transferring the recording material adhered on the recording paper to the recording paper, the developing means supplying the recording material to the latent image on the surface of the recording medium (A), and the latent image A recording apparatus comprising: a stimulating member that applies a stimulus to the recording material supplied to the recording apparatus. (A) A recording body provided with a surface layer having a property of reducing a receding contact angle when heated and brought into contact with a liquid. (B) A liquid, a vapor, or a solid that becomes a liquid or generates a liquid or a vapor at a temperature at which the receding contact angle of the recording medium (A) starts to decrease.

A second recording apparatus of the present invention is a recording medium described below.
By selectively heating the surface of (A) in contact with the recording material or by contacting the surface of recording material (A) with the recording material of recording material (A) A developing means for forming a latent image having a receding contact angle according to the heating temperature on the surface and at the same time attaching the recording material to the latent image for moderation, and selecting the surface of the recording medium (A) according to the image signal. In the recording apparatus provided with a means for heating the recording material (A) to form a latent image and a means for transferring the recording material adhering on the recording material (A) to the recording paper, the developing means is used for developing the latent image on the surface of the recording material (A). A recording apparatus comprising: a recording agent supply unit for supplying a recording agent to an image; and a stimulating member for stimulating the recording agent supplied to the latent image. (A) A recording body provided with a surface layer having a property of reducing a receding contact angle when heated and brought into contact with a liquid.

In such an apparatus of the present invention, if a recording material (such as liquid ink) is used as the contact member (B) as seen in the second aspect of the invention, an image is formed at the same time as latent image formation. Therefore, the supply means of the contact member (B) and the recording agent supply means can be integrated, and the supply means of the contact member (B) can be omitted.

The present invention will be described in more detail below. When the recording medium (A) used in the apparatus of the present invention is heated in contact with a liquid, its receding contact angle becomes low even after cooling, and the receding contact angle becomes high due to heating in the absence of liquid. At least the surface is formed of a member having a function. The recording material (A) having such a function has a surface whose member is (1) a member containing an organic compound having a surface self-alignment function of a hydrophobic group, or (2) an organic compound having a hydrophobic group and having a hydrophobic group. Is a member whose surface is oriented.

The "surface self-orienting function" mentioned in (1) means that when a solid formed by depositing a certain compound on a support or a solid formed by the certain compound itself is heated in air, the hydrophobic group on the surface becomes free (to the free side). It means that it has a property of being oriented toward the surface side). This also applies to (2). Generally, in an organic compound, the hydrophobic group has a property of being easily oriented toward the hydrophobic atmosphere. This is a phenomenon that occurs because the interface energy of the solid-gas interface becomes lower. Further, this phenomenon is observed as the molecular length of the hydrophobic group becomes longer, and this is because the mobility of the molecule upon heating increases as the molecular length becomes longer.

More specifically, the terminal has a hydrophobic group.
If it is a molecule (that is, that lowers the surface energy),
It is easy to orient to the surface (free surface side). Similarly (-CH ₂
In the linear molecule containing −) n, the (—CH ₂ CH ₂ —) portion has a planar structure, and the molecular chains are easily oriented. Also,
In the molecule containing (-Ph-) n, the -Ph- portion has a planar structure, and the molecular chains are easily oriented. Note that -Ph- is p
-A phenylene group (hereinafter the same). Particularly, a linear molecule containing an element having a high electronegativity such as fluorine has a high self-aggregating property, and the molecular chains are easily oriented.

Summarizing the results of these studies, it is more preferable that a straight-chain molecule having a molecule having a planar structure containing a molecule having a high self-aggregating property and having a hydrophobic group at the terminal, or such a straight-chain molecule. It can be said that the compound containing the linear molecule has a high surface self-orientation function.

As is clear from the above description, there is a relation between the surface self-alignment state and the receding contact angle, and also between the receding contact angle and the liquid adhesion. That is, the adhesion of the liquid on the solid surface occurs mainly by the tacking of the liquid on the solid surface. This tacking can be regarded as a kind of frictional force when the liquid slides on the solid surface. Therefore, in the "receding contact angle" θr in the present invention, cos θr = γ (γs−γse−πe + γf) / γev (where γ: surface tension of solid in vacuum γse: solid-liquid interface tension γev: liquid Surface tension when in contact with saturated vapor πe: Equilibrium surface tension γf: Friction tension γs: Surface tension of solid without adsorbed layer) such as Saito, Kitazaki et al. .22, No. 12, 1986). Therefore, when the value of θr decreases, the value of γf increases. That is, the liquid does not easily slide on the solid surface, and as a result, the liquid adheres to the solid surface.

As can be inferred from these mutual relationships,
The liquid adhesion depends on the degree of the receding contact angle θr, and the receding contact angle θr is determined by the member having the surface self-orienting function on the surface. Therefore, in the apparatus of the present invention, the recording material (A) necessarily has a member having a surface self-alignment function on the surface because of the necessity of forming a desired pattern area on the surface and / or visualizing with a recording agent. Must be selected.

The relationship between the receding contact angle and the liquid adhesion property has been described so far, and these matters are described in detail in the above-mentioned Japanese Patent Laid-Open No. 3-178478.

The liquid of the contact material (B) is as described above, but the contact material (B) is, to put it simply, a liquid or a vapor from the beginning, or the recording material (A). It is a solid that eventually produces a liquid at a temperature below the temperature at which the receding contact angle θr is lowered. The vapor here is the recording medium (A)
It is sufficient that at least a part of the surface of the recording medium condenses to form a liquid, and the liquid can wet the surface of the recording medium (A). On the other hand, the solid here is a liquid, a liquid is generated, or a vapor is generated at a temperature at which the receding contact angle θr is decreased or lower. The vapor generated from the solid is condensed on the surface of the recording medium (A) or in the vicinity thereof to generate a liquid, as in the case described above.

More specifically, the contact materials (B) are as follows. That is, as the liquid that is one of the contact members (B), in addition to water, an aqueous solution containing an electrolyte, ethanol, alcohols such as n-butanol, glycerin, polyhydric alcohols such as ethylene glycol, ketones such as methyl ethyl ketone, etc. And polar liquids such as n-nonane and n-octane, linear hydrocarbons such as cyclohexane, and non-polar liquids such as aromatic hydrocarbons such as m-xylene and benzene. . Also, a mixture of these may be used, and various dispersions and liquid inks can also be used. More desirably, polar liquids are better. In addition to steam, which is another one of the contact members (B),
Any liquid vapor of the contact member (B) can be used, but in particular vapors of organic compounds such as ethanol vapor and m-xylene vapor (including those in a spray state) can be mentioned. The temperature of the organic compound vapor needs to be lower than the melting point or softening point of the compound forming the surface of the recording material (A). Contact member (B)
Other examples of solids include higher fatty acids, low molecular weight polyethylene, polymer gels (polyacrylamide gel, polyvinyl alcohol gel), silica gel, and compounds containing water of crystallization.

As a means for supplying the contact member (B), for example, a plate is provided below the recording medium (A) so that the plate is filled with liquid so that the recording medium (A) is always in contact with the liquid in the plate, and the heating source is near the plate. Alternatively, the simplest configuration is one arranged in a dish. Instead of the dish, a sponge-like porous body containing a liquid may be used.

As a heating means for forming a latent image in the present invention, in addition to contact heating by a heater, a thermal head, etc., an electromagnetic wave (a light beam from a source such as a laser light source or an infrared lamp is condensed by a lens) is used. There is non-contact heating.

When the transfer of one image information is completed, the surface of the recording medium (A) is heated in the absence of liquid or vapor (in air, in vacuum or in an inert gas) (heating temperature: 50 to 50). Thirty
0 ° C, preferably 100 to 180 ° C, heating time; 1 msec to
If the latent image is erased by 10 seconds, preferably 10 msec to 1 second, the recording medium (A) can be used repeatedly.

As a heating means for erasing the latent image, non-contact heating by electromagnetic waves such as a heater, a contact heating source such as a thermal head, a laser light source, and an infrared lamp is preferable. Heating may be applied only to the latent image area, but
(A) You may do it all over. Rather, it is preferable to heat the entire surface because the device structure can be simplified.

The latent image erasing means is provided at a position where the surface of the recording medium (A) is substantially cooled during the time until the latent image is formed again after heating for erasing.
The heating temperature necessary for erasing the latent image is as described above, but it depends on the material of the surface of the recording material (A), but the recording material (A)
It is desirable that the temperature is not lower than the decomposition temperature and not higher than the decomposition temperature at which the receding contact angle of the material on the surface becomes low.

As the recording agent, a recording agent such as a writing ink, an ink jet recording ink, a printing ink, a toner for electrophotography, etc., which is suitable for the apparatus of the present invention, can be used. Can be selected and used. More specifically and preferably, the water-based ink is, for example, a water-soluble ink mainly composed of water, a wetting agent or a dye, or a water-based pigment dispersion ink mainly composed of water, a pigment, a polymer compound for dispersion and a wetting agent. An emulsion ink in which a pigment or dye is dispersed in water using a surfactant is used.

As the recording paper (transferred material), a transparent or opaque resin film, plain paper, synthetic paper, ink jet recording paper, type paper or the like can be used.

After the latent image is formed by the latent image forming means or at the same time as the formation of the latent image, the latent image is converted into an image by the developing means.
It is characterized by comprising a recording agent supplying means for supplying a recording agent to the latent image on the surface of the recording medium (A) and a stimulating member for stimulating the recording agent supplied to the latent image.

FIG. 1 is a view of the recording body as seen from the cross-sectional direction, which is the same as that of the recording body 21 seen from the cross-sectional direction of cc in FIG. The principle of the device of the present invention will be described with reference to FIG.
When characters are crushed in an image obtained by transferring a recording material (for example, ink) onto a recording paper, the ink supply state on the surface of the recording medium is as shown in FIG. It also adheres to the non-latent image portion 29 between the image portion 28 and the latent image portion. Therefore, when a stimulating member 4-4 (for example, a thin linear member) is brought into contact with the attached ink to give a stimulus as shown in FIG. 1B, the non-latent image portion 29 is formed so that a soap bubble can be repelled, as shown in FIG. 1C. The inventors of the present invention have found that the ink of (3) pops and the ink of the non-latent image part moves and adheres to the latent image part. This is because the non-latent image portion of the surface of the recording medium has stronger ink repellency than the latent image portion, and therefore the ink of the non-latent image portion that can be moved by the stimulus of the stimulating member has the surface tension of the ink of the latent image portion. By combining with the ink in the latent image area. As described above, the principle of the present invention is to prevent the recording agent from adhering to the non-latent image portion by applying some kind of stimulus to the recording agent supplied to the surface of the recording medium and to eliminate the crushed characters. is there.

The structure of the stimulation member will be specifically described.
FIG. 2 shows the fibrous member 11 supported by the support rod 10. The tip of the thin fibrous member is attached to the recording agent 4 on the surface of the recording body 1.
It is a device that gives a stimulus by touching -1 (eg ink).
The fibrous member may be made of metal, glass, resin, or the like, and its shape and length are not particularly limited, but the following conditions are preferable. The finer the diameter of the fiber, the better, and the range of approximately 20 to 100 μm is desirable.
The fiber density in the direction perpendicular to the moving direction of the recording medium is preferably about the latent image dot pitch. The fiber density in the direction perpendicular to the moving direction of the recording medium is not particularly limited, but it is preferable that the thickness of the entire fibrous member be equal to or less than several times the thickness between latent image dots. Further, it is desirable that the fiber surface exhibits ink repellency with respect to ink.

FIG. 3 shows another specific example of the recording material 4-1.
This is a device using a liquid absorbing roller 12 made of a liquid absorbing material capable of absorbing ink as a stimulating member for stimulating (for example, ink). The liquid absorbing roller is the recording material 4-1 on the surface of the recording medium
When it comes into contact with (for example, ink), the ink is absorbed by the liquid absorbing roller, and the ink is stimulated. (FIG. 3 (B)). In this apparatus, if the liquid absorbing force of the liquid absorbing roller is too strong, all the ink will be absorbed by the roller. It is preferable that the liquid absorbing member does not have a strong liquid absorbing force.As the material of the liquid absorbing member, a resin foam material such as urethane foam or a woven fabric made of metal or resin fiber is preferable, and the pore diameter and the texture are the surface of the ink. Set according to the tension and adjust so that it has an appropriate liquid absorption force.

Further, as the arrangement of the stimulating member, as shown in FIG. 4 (FIG. 4 (A) fibrous member, FIG. 4 (B) liquid absorbing roller), the stimulating member is in complete contact with the surface of the recording body 1. It is better to be a little slack than to do. As long as it is not in contact with the surface of the recording medium, it will not damage the surface of the recording medium, and
Since the ink does not adhere to the stimulating member so much, the ink adhering to the latent image portion is kept in an appropriate amount.
