Especially high definition and /
Alternatively, the present invention relates to a material and a recording method capable of creating a full-color image by digital dry processing.

2. Description of the Related Art Conventionally, for thermal transfer recording, a thermal transfer ink sheet having a heat-fusible coloring material layer or a coloring material layer containing a heat sublimable dye provided on a substrate and a recording medium are opposed to each other, and a thermal head, There is a method of transferring and recording an image by pressing a heat source controlled by an electric signal such as an energizing head from the ink sheet side.

The thermal transfer recording has features such as noise-free, maintenance-free, low cost, easy colorization and digital recording, and is used in various fields such as various printers, recorders, facsimiles and computer terminals. There is.

On the other hand, in recent years, a so-called digital recording method having a high resolution and capable of high-speed image processing has been demanded in the fields of medicine, printing and the like.

However, in the conventional thermal transfer recording method using a thermal head or a current-carrying head as a heat source, it is difficult to increase the density in terms of the life of the head heating element. In order to solve this, thermal transfer recording using a laser as a heat source is disclosed in JP-A-49-15437, JP-A-49-17743, JP-A-57-87399 and 59.
-143659, etc.

In thermal transfer recording using a laser as a heat source, the resolution can be increased by narrowing the laser spot. However, in the case of recording with a laser, it is general to perform scanning type recording, and in terms of recording speed, scanning type recording has a higher recording speed than batch exposure using a mask material or a recording method using a line head. It has the drawback of being slow. In order to increase the recording speed, it is necessary to increase the laser scanning speed.

As a laser scanning method, a polygon mirror or a galvanometer mirror and an fθ lens are combined to perform main scanning of laser light, and sub-scanning is performed by moving a recording medium. However, there are cylindrical scans that perform laser exposure and drum rotation as main scanning and laser light movement as sub-scanning, but cylindrical scanning that allows high-density recording with little energy loss in the optical system is suitable for heat mode recording. Appropriate. In this case, it is easy to increase the scanning speed by increasing the rotation speed of the drum, but it is difficult to obtain the close contact between the thermal transfer material and the recording material required for transfer. In thermal transfer recording with a thermal head, it is possible to obtain close contact between the thermal transfer material and the recording material by the pressure between the platen and the heating element of the thermal head, but such a method cannot be taken with cylindrical scanning,
Further, Japanese Patent Laid-Open No. 61-112665 discloses that laser exposure is performed while applying pressure with a transparent pressing member or the like, but uniform pressing becomes difficult when the drum is rotated at high speed for high-speed recording, and adhesion unevenness becomes difficult. Fogging easily occurs due to pressure transfer.

On the other hand, a thermal transfer recording material having an intermediate layer and an ink layer on a support has been proposed in order to improve the adhesion between the recording material and the image receiving material or for other reasons. For example, in JP-A-60-225795, a rubber-based resin layer having a Young's modulus of 1.0 × 10 ⁸ Nm ⁻² or less at 50 ° C. is 5 μm between a support and a heat-fusible color material layer.
It is disclosed that by providing the sheet with a thickness of m or less, it is possible to satisfactorily print from paper with high smoothness to paper with low smoothness with a thermal head.

Further, in JP-A-57-36698, a resin layer for increasing the adhesive force between a support made of polyvinyl butyral, epoxy or the like and an ink layer is provided as an intermediate layer in an amount of 1 to 3 μm, and aggregation in the ink layer is provided. There is a disclosure of a thermal transfer sheet that is easily broken and can be used many times.

Further, in Japanese Patent Laid-Open No. 57-138984, by providing an adhesive layer of 6 μm of a heat-melting polyamide and carbon black as an intermediate layer, the ink layer is not peeled from the ink ribbon and only the ink material is recorded. There is a disclosure of a technique that enables permeation transfer to paper to enable repeated printing. JP 58-1
No. 16193 also relates to a manufacturing method in which an adhesive layer made of heat-melting polyamide and carbon black is applied and dried as an intermediate layer and then heat-treated to provide an ink layer. There is a disclosure of a technique for obtaining an ink ribbon having a high printing density without peeling of the ink, and Japanese Patent Laid-Open No.
-109897 has a configuration in which a 1-2 μm intermediate layer and a 2-4 μm ink layer are provided on a 3-5 μm PET, and a rubber latex or synthetic rubber material is used for the intermediate layer, and smoothness is 10
A technique is disclosed in which good printing can be performed even on recording paper for about 0 to 300 seconds.

All of these techniques have the same weak adhesion pressure (up to 1.0 k as the object of the present invention).
It is clearly different from the technique for obtaining good adhesion at g / cm ² ) and therefore the constitution of the invention is also different from the constitution of the present invention.

Further, heat mode recording, particularly heat mode recording using a laser, requires more recording energy than photon mode recording such as silver salt photography and electrophotography. At this time, a high-power water-cooled laser can be used as a light source, but it is preferable to use a laser light source having a lower output from the viewpoints of downsizing of the device, cost, environment of use, and the like. Therefore, in order to perform high speed recording, it is preferable to increase not only the scanning speed but also the material sensitivity.

Further, JP-A-61-144394 and JP-A-61-258793,
61-279582, 62-151393, 64-5885, 64-26
No. 497 and the like disclose the technology of an image receptor having a cushion layer between the support and the image receptor layer, but these are all related to thermal transfer of sublimable dyes, and the heating method is also a thermal head, Further, this is a technique in which it is not necessary to transfer the image once formed on the image receiving material to the final recording body again. Therefore, the technology disclosed in these patents is different from the technology of the present invention.

(C) The surface of the photothermal conversion type heat mode image receiving material on the side of the deformable layer and the ink surface of the photothermal conversion heat mode recording material are superposed to each other to form a photothermal conversion type heat mode recording material or a photothermal conversion type heat mode image receiving material. Of the photothermal conversion type heat mode image-receiving material carrying the ink layer after the ink layer is transferred to the image receiving surface of the photothermal conversion type heat mode image receiving material according to the image information. A photothermal conversion type heat mode thermal transfer recording method in which an image receiving surface is superposed on a recording surface of a final recording medium and an ink layer on the image receiving surface is retransferred to the final recording surface under heating and / or pressure.

The intermediate layer of the photothermal conversion heat mode recording material has an elastic modulus at 25 ° C. of 250 kg / mm ² or less, a glass transition temperature of 80 ° C. or less, and a needle of the intermediate layer. It is a preferable mode that the penetration is 15 or more under the standard test condition of JIS K2530-1976, and the thickness of the intermediate layer is 5 μm or more, because the effects of the present invention can be further realized.

Further, the elastic modulus of the deformable layer of the photothermal conversion heat mode image receiving material is not more than 200 kg / mm ^{2 at} 25 ° C., the viscosity of the deformable layer is not more than 10,000 cp at 200 ° C. The glass transition temperature of the layer is 80 ° C or less, the penetration of the deformable layer is 15 or more under the standard test conditions of JIS K2530-1976, and the deformable layer and / or the image receiving layer can absorb heat rays. It is a preferable mode to contain such a coloring material because the effects of the present invention can be further realized.

The present invention will be described in more detail below. The photothermal conversion type heat mode recording material, the image receiving material and the recording method are referred to as "heat mode recording material, image receiving material, recording method" or further "recording material, image receiving material". , "Recording method".

In general, it is difficult to achieve complete contact between the recording material and the image receiving material by non-contact contact by vacuum contact. Therefore, during exposure printing, transfer defects due to poor adhesion are likely to occur.

As a result of the research conducted by the present inventors, a recording material and an image receiving material were obtained by using a recording material having an ink layer formed on a support having sufficient cushioning property due to the thermal energy converted during exposure. It was found that a good transferred image with no omission can be obtained even if the complete close contact is not achieved. It is considered that this is because the support has a cushioning property due to the heat generated at the time of exposure, and the adhesion required for transfer is achieved.

However, the support having a sufficient cushioning property due to the thermal energy converted during the exposure has insufficient rigidity as the support and is often poor in slipperiness. Is difficult to carry automatically. It is possible to increase the film thickness of the support in order to improve transportability, but with a support having sufficient cushioning properties,
It is difficult to obtain rigidity for obtaining transportability simply by increasing the thickness. Therefore, as a result of examination, it is clear that in vacuum contact, it is preferable that the recording material has a rigid support in order to provide rigidity and a cushioning intermediate layer in order to obtain cushioning property. became.

Further, it is preferable that the cushioning intermediate layer is deformed so that the foreign matter is embedded when the foreign matter is caught when the recording material and the image receiving material are superposed on each other. As a result, even if there is a foreign substance, it is possible to prevent an image defect from occurring in that portion.

By adopting such a constitution, it was found that the adhesiveness required for transfer at the time of exposure (shortening of the pressure reduction time for obtaining the adhesiveness) and the transportability can be made compatible, and the present invention was completed.

On the other hand, as a result of studies conducted by the present inventors, the use of an image receiving material in which an image receiving layer is formed on a support having sufficient elasticity improves the adhesion between the recording material and the image receiving material, and is excellent in that there is no omission. It was found that a transfer image could be obtained. It is considered that this is because the support has deformability and the close contact required for transfer is achieved. However, in such a material in which the support itself is deformable, the strength and dimensional stability of the support are insufficient, and it has been difficult to form a highly accurate image.

As a result of further studies, it was found that the adhesion is improved by providing the image receiving material with a suitable deformable layer so as to have the deformability. In addition, when the image formed on the image receiving material is superposed on a transfer material such as art paper, coated paper, or high-quality paper and retransferred by heating and / or pressing to obtain a final image, the image receiving material is Without the deformable layer, the retransferred paper has a waviness on the surface of the paper, so that sufficient adhesion cannot be obtained and the retransferred image lacks or is chipped. Therefore, it has been clarified that the image can be transferred to the final recording medium by making the deformable layer of the image receiving material thick enough.

The deformable layer of the image receiving material may have good adhesion and may be deformable enough to follow the swell of the final recording medium such as art paper, coated paper, and fine paper at the time of retransfer. preferable.

Furthermore, it is preferable that the deformable layer is deformed so that the foreign matter is embedded when the foreign matter is caught when the recording material and the image receiving material are superposed on each other. As a result, even if there is a foreign substance, it is possible to prevent an image defect from occurring in that portion.

Furthermore, the image receiving material must have a certain degree of rigidity so that it can be automatically conveyed in the apparatus and can be automatically wound around the holding member for holding the recording material and the image receiving material. For this purpose, it is preferable that the support itself of the image receiving material has rigidity, like the recording material.

As a result of the above examination, it has been clarified that the object of the present invention can be achieved by satisfying any of the above structural requirements.

A typical process of the photothermal conversion type heat mode recording method will be described below with reference to the drawings.

As a contacting method, as shown in FIG. 1, the image receiving layer surface of the image receiving material and the ink surface of the recording material having a vertical and horizontal dimension larger than that of the image receiving material are superposed on a depressurizer having micropores, and the periphery of the image receiving material is overlapped. The image receiving material and the recording material are brought into close contact with each other by decompressing through the minute holes from the portion of the recording material that is more protruding, and conversely, the ink surface of the recording material and the image receiving surface of the image receiving material having a vertical and horizontal dimension larger than that of the recording material are superposed. It is also possible to bring the image receiving material and the recording material into close contact with each other by reducing the pressure through the minute holes from the image receiving material portion protruding from the periphery of the recording material.

According to this contact method, the recording material and the image receiving material can be easily conveyed and wound together automatically, and heat mode recording can be performed by irradiating light after completion of contact. The decompressor may be drum-shaped as shown in FIG. 2, or may be a flat plate as shown in FIG. 3, but when high-speed recording is required, a flat plate decompressor and a polygon mirror or a galvano mirror are used. Cylindrical scanning using a drum-shaped decompressor requires less optical system loss than planar scanning by.

Recording information is recorded in such a state that the ink surface of the recording material and the image receiving surface of the image receiving material are completely in close contact with each other or placed in the immediate vicinity thereof (hereinafter, this state is referred to as a close contact state) by using such a decompressor. Thermal transfer recording is performed by irradiating light according to the above.

FIG. 4 shows the pressure reducer and its surroundings in the present invention.

Here, the case where the decompressor is in the form of a drum is illustrated, but the basic structure is the same in the case of a flat plate. For example, when the recording material and the image receiving material having the structure shown in FIG. 5 are wrapped around the decompressor and brought into close contact with each other, first, the image receiving material is depressurized with the decompression hole valve closed and wrapped and fixed. Next, the recording material is wound, and at this time, the pressure reducing holes are sequentially opened. This makes it easier to shorten the decompression time and obtain a close contact state. It is more effective to open the pressure reducing valve while pressing it with the squeeze roller.

Next, the recording material and the image receiving material used in the present invention will be described.

In addition, a cushioning intermediate layer JIS K2530-19
Penetration under standard test conditions of 76 is 15 to 500, more preferably 30 to 300.

As the cushioning intermediate layer, a shape memory resin such as polynorbornene or a styrene hybrid polymer in which a polybutadiene unit and a polystyrene unit are compounded can also be used.

The intermediate layer satisfying the preferable conditions of the present invention is

Examples of the additives include low melting point substances such as wax and plasticizers.

And a method of laminating a cushioning film can be applied.

The thickness of the intermediate layer is required to be 5 μm or more so that it can be sufficiently adhered to the image receiving material, and more preferably 10 μm.
That is all. Further, when a foreign substance is sandwiched between the recording material and the image receiving material, the thickness of the intermediate layer is preferably 20 μm or more in order to prevent the image defect by deforming so that the foreign substance is embedded.

In the photothermal conversion type heat mode recording (hereinafter, also referred to as "heat mode recording"), the energy loss due to heat conduction from the ink layer to the support side is reduced by shortening the exposure time. In the heat mode recording, the thermal energy applied to the parts other than the ink layer is small as compared with the ordinary thermal transfer recording in which the ink layer is heated by the heat conduction from the support side using the thermal head. Therefore, it is considered that the intermediate layer needs to have a sufficient cushioning property due to the thermal energy generated in the ink layer during exposure. Therefore, it is considered that the intermediate layer needs to have a sufficient cushioning property due to the thermal energy generated in the ink layer during exposure. The Tg of the resin forming the intermediate layer is preferably 80 ° C. or lower, more preferably 40 ° C. or lower, in order to lower the elastic modulus or heat-soften by this slight amount of heat.

In order for the energy of the light source for heat mode recording to be absorbed in the ink layer without waste, the transmittance for the wavelength of the light source through the support and the intermediate layer is preferably 70% or more, more preferably 80% or more. For this purpose, it is necessary to use a highly transparent support and an intermediate layer, and to reduce reflection at the BC plane of the support and the interface between the support and the intermediate layer.

As a method for reducing the reflection at the interface between the support and the intermediate layer, the refractive index of the intermediate layer is set to be 0.1 or more smaller than that of the support so that the loss of light energy due to the interface reflection is significantly reduced. Can be reduced to

Ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polybutadiene resin, styrene-
Butadiene copolymer (SBR), styrene-ethylene-butadiene copolymer (SEBS), acrylonitrile-butadiene copolymer (NBR), polyisoprene resin (I
R), styrene-isoprene copolymer (SIS), acrylic ester copolymer, polyester resin, polyurethane resin, butyl rubber, polynorbornene, etc.

Among these, those having a relatively low molecular weight are likely to satisfy the requirements of the present invention, but they are not necessarily limited in relation to the material.

Further, even with materials other than the above, by adding various additives, preferable characteristics can be obtained in the deformable layer.

Examples of the additives include low melting point substances such as wax and plasticizers. Specific examples thereof include phthalic acid ester, adipic acid ester, glycol ester, fatty acid ester, phosphoric acid ester and chlorinated paraffin. Also, various additives described in, for example, "Practical Handbook of Additives for Plastics and Rubbers", Kagaku Kogyo Co., Ltd. (issued in 1970) can be added. The amount of these additives to be added may be selected in an amount necessary for expressing the physical properties of the present invention in combination with the base deformable layer material, and is not particularly limited, but generally, the total deformable layer It is preferably 10% by weight or less, more preferably 5% by weight or less of the amount of the raw material.

As the method for forming the deformable layer, a material obtained by dissolving the above materials in a solvent or dispersing them in a latex form is applied by a blade coater, a roll coater, a bar coater, a curtain coater, a gravure coater or the like, or is extruded by hot melt. The lamination method etc. can be applied.

The thickness of the deformable layer is preferably 10 μm or more, more preferably 20 μm or more. Further, when retransferred to another recording material (for example, paper such as coated paper or high-quality paper), a film thickness of 30 μm or more is preferable. When the film thickness of the deformable layer is 10 μm or less, voids or chips may occur during retransfer to the final recording material.

The image-receiving layer is composed of a binder and various additives and mat materials which are added as necessary. Further, in some cases, it is formed only by the binder.

As the image-receiving layer binder having good transferability,
Polyvinyl acetate emulsion adhesives, chloroprene adhesives, epoxy resin adhesives and other adhesives, natural rubber,
Adhesive materials such as chloroprene rubber-based, butyl rubber-based, polyacrylic acid ester-based, nitrile rubber-based, polysulfide-based, silicon rubber-based, rosin-based, petroleum-based resins, recycled rubber, vinyl chloride-based resin, SBR, polybutadiene resin, polyisoprene , Polyvinyl butyral resin, polyvinyl ether, ionomer resin, styrene resin, styrene-acrylic resin, acrylic resin and the like.

When the image formed on the image receiving layer is retransferred to another recording medium by further heating and / or pressing, a resin having a relatively small polarity (small SP value) is used as the image receiving layer. Is particularly preferable. For example, polyethylene, polypropylene, ethylene-vinyl chloride copolymer, ethylene-acrylic copolymer, ethylene-vinyl acetate resin (EV
A), vinyl chloride graft EVA resin, EVA graft vinyl chloride resin, vinyl chloride resin, various modified olefins, polyvinyl butyral, polyvinyl acetal resin and the like.

The film thickness of the image receiving layer is usually 0.5 to 10 μm, but it is not limited to this when the deformable layer is used as the image receiving layer.

The exposure method includes a method of exposing from the support side of the recording material with the recording material and the image receiving material being in close contact with each other,
A method of exposing through an image receiving material can be considered.

When the recording material is exposed from the support side, the image receiving layer and / or the deformable layer can absorb heat rays so that the image receiving layer and / or the deformable layer absorbs the light which cannot be absorbed by the recording material. Adding a coloring material to efficiently use heat is also effective in improving transferability.

In the latter case, the transmittance of the light source through the image receiving material to the wavelength of the light source is preferably 70% or more, more preferably 80% or more, in order to absorb the energy of the light source in the ink layer without waste. For this purpose, it is necessary to use a highly transparent support and an intermediate layer, and to reduce reflection at the backcoat surface of the support and the interface between the support and the deformable layer. As a method for reducing the reflection at the interface between the support and the deformable layer, it is preferable to make the refractive index of the deformable layer smaller than that of the support by 0.1 or more.

A deformable material may deteriorate the slipperiness by causing deformation, and thus the slipperiness of the image receiving layer and the ink layer may be deteriorated. As a result, it may be difficult to adhere a large area, and it may be difficult to carry out automatic conveyance in the recording apparatus. In such a case, it is possible to deal with it by providing an image receiving layer having good slipperiness on the deformable layer.

In order to obtain an image-receiving layer having good slipperiness, addition of a mat material or a material having good slipperiness may be mentioned.

The addition of fine particles (matting material) to the image receiving layer is effective in improving the slipperiness of the recording material and the image receiving material. However, if the addition amount of the matting material is excessively increased, a gap is generated between the recording material and the image receiving material, which deteriorates the transferability. The amount of the matting material added depends on the particle size and the thickness of the image receiving layer. For example, when forming an image receiving layer of 1 μm,
15-150 mg / m ² , 2.0-3.5μ for 0.8-1.5μm matte material
5 to 30 mg / m ² for m mat material, 10 mg for 5 μm mat material
/ M ² or less is preferable.

Examples of materials having good slipperiness include polyethylene resin, polypropylene resin, silicon resin, Teflon resin and the like.
