BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receptor layer transfer sheet, a thermal transfer image receptor sheet and a method for producing the same, and more specifically to a dye receptor capable of forming a high-quality image on any image receptor sheet without defects such as white spots and chips.

2. Description of the Related Art Conventionally, various thermal transfer methods have been known. Among them, a sublimation dye is used as a recording agent, which is carried on a base material sheet such as paper or plastic film to form a thermal transfer sheet. There have been proposed methods for forming various full-color images on an image-receiving sheet such as a layered paper or plastic film. In this case, the thermal head of the printer is used as the heating means, and a large number of three-color or four-color dots are transferred to the image-receiving sheet by heating for an extremely short time, and the full-color image of the original is formed by the multi-color dots. It is to be reproduced. The image formed in this way is extremely clear because the coloring material used is a dye and has excellent transparency, so the resulting image has excellent reproducibility of intermediate colors and gradation, and It is possible to form a high quality image which is similar to the image obtained by the offset printing or gravure printing and which is comparable to the full color photographic image.

[0003]

[Problems to be solved by the invention] However,
The image-receiving sheet capable of forming an image by the above method is limited to a dye-staining plastic sheet or a paper having a dye-receiving layer provided in advance, and a problem that an image cannot be directly formed on ordinary plain paper. For that reason, it is known that a dye receiving layer is provided on these image receiving sheets by a coating method or a transfer method. Further, since these dye receiving layers are formed of a resin having a relatively high softening point in order to prevent fusion with the thermal transfer sheet, the cushioning property is insufficient, and dots or missing dots occur in the formed image. There is a problem. As a method for solving such a problem, a method of forming a foamed layer under the receiving layer to provide cushioning properties has been proposed, and good performance has been obtained. However, when the cushion layer is formed by a coating method, a transfer method, or the like, it is necessary to apply an ink in which air bubbles or a foaming agent is dispersed in water or a solvent containing a binder.
When the air bubbles or the foaming agent used have a large particle size, it is difficult to apply a uniform and dense film, and the surface smoothness of the formed film is lacking, and the manufactured thermal transfer image-receiving sheet is rolled. There are various problems such as being bulky when wound, and further adversely affects the surface smoothness of the receiving layer formed on the surface of the bubble-containing layer, resulting in missing dots or chipping during image formation, and high quality images cannot be obtained. There is a problem to say. Further, when the thermal transfer image-receiving sheet contains an unfoamed foam material, the foam material is not sufficiently foamed at the time of low-energy printing, and there is a problem that the image quality of the highlight portion is inferior. Therefore, an object of the present invention is to solve the above-mentioned problems and to form a high-quality and high-density image on a rough paper or the like whose surface is not smooth without white spots or defects and a thermal transfer image-receiving sheet. Is to provide a sheet.

[0005]

The above object can be achieved by the present invention described below. That is, in the present invention, a transferable resin layer is provided on one surface of a substrate sheet, the transferable resin layer includes a dye receiving layer and a bubble-containing layer, and the bubble-containing layer has an average particle diameter of 20 μm or less. Receptor layer transfer sheet, characterized in that it contains a bubble and / or a foaming agent, a resin layer is provided on one surface of the substrate sheet, the resin layer comprising a dye receiving layer and a bubble-containing layer, The bubble-containing layer has an average particle diameter of 40 μm.
A thermal transfer image-receiving sheet characterized by containing the following bubbles and / or a foaming agent, and a method for producing a thermal transfer image-receiving sheet characterized by transferring a transferable resin layer of the above-mentioned receptor layer transfer sheet to a substrate sheet. is there.

[0006]

By incorporating bubbles and / or a foaming agent having an average particle size of 20 μm or less (in the case of a transfer layer transfer sheet) or 40 μm or less (in the case of a thermal transfer image-receiving sheet) in the bubble-containing layer, the composition is uniformly dense and smooth. An excellent bubble-containing layer is formed, so the surface smoothness of the dye-receiving layer formed on it is improved, and high-quality and high-density images with no white spots or defects are formed even on rough paper whose surface is not smooth. It is possible to provide a receptive layer transfer sheet and a thermal transfer image receiving sheet that enable the above. Further, in the case of the thermal transfer image-receiving sheet, when the foaming agent has already been foamed, the energy during dye transfer is less consumed in foaming, so a sufficient cushion can be obtained even if the printing energy is low. A quality image is formed.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the following preferred embodiments. One example of the receptor layer transfer sheet of the present invention comprises a transfer resin layer A provided on one surface of a base material sheet 1 as schematically shown in FIG. It is characterized in that it includes a layer 2 and a bubble-containing layer 3, and the bubble-containing layer 3 contains bubbles and / or a foaming agent having an average particle diameter of 20 μm or less. The intermediate layer 4 and the adhesive layer 5 may be provided in the resin layer, and the heat resistant slipping layer 6 may be further provided in the resin layer. These intermediate layers or adhesive layers can also contain cells and / or blowing agents.
As the base material sheet used in the receiving layer transfer sheet of the present invention, the same base material sheet as that used in the conventional thermal transfer sheet can be used as it is, and other materials can also be used and are not particularly limited. .. Specific examples of the preferable substrate sheet include, for example, thin paper such as glassine paper, condenser paper, paraffin paper, polyester,
Examples thereof include polypropylene, cellophane, polycarbonate, cellulose acetate, polyethylene, polyvinyl chloride, polystyrene, nylon, polyimide, polyvinylidene chloride, ionomer, and other plastics, or a base sheet obtained by combining these with the preceding paper. The thickness of the base sheet can be appropriately changed depending on the material so that the strength, heat resistance and the like are appropriate, but the thickness is preferably 3 to 100 μm.

Prior to the formation of the receiving layer, it is also preferable to form a release layer (not shown) on the surface of the substrate sheet. The release layer is formed of a release agent such as water-soluble resin, hydrophilic resin, waxes, silicone wax, silicone resin, fluororesin, acrylic resin and the like. The formation method may be the same as the formation method of the receiving layer described later, and the thickness of about 0.1 to 5 μm is sufficient. If a matte receiving layer is desired after transfer, it may be formed into a matte surface by incorporating various particles in the release layer or by using a base sheet having the release layer side surface matt treated. I can. Of course, when the above-mentioned base material sheet has an appropriate releasability, it is not necessary to form the release layer.

The dye receiving layer formed on the surface of the above-mentioned base sheet or release layer receives the sublimable dye transferred from the thermal transfer sheet after transferring the receiving layer to any image receiving sheet, and forms an image on the formed image. It is for maintaining. Examples of the resin for forming the dye receiving layer include polyolefin resins such as polypropylene, vinyl chloride-vinyl acetate copolymer, halogenated polymers such as polyvinyl chloride and polyvinylidene chloride, polyvinyl acetate, polyacrylic ester. Such as vinyl polymers, polyethylene terephthalate, polyester resins such as polybutylene terephthalate, polystyrene resins, polyamide resins, copolymer resins of olefins such as ethylene and propylene with other vinyl monomers, ionomers, cellulose diacetate, etc. Cellulose resins, polycarbonates and the like can be mentioned, and particularly preferable ones are vinyl resins and polyester resins.

Preferred releasing agents to be mixed with the above resins include silicone oils, phosphate ester type surfactants and fluorine type surfactants, with silicone oils being preferable. As the silicone oil, a modified silicone oil such as epoxy modified, alkyl modified, amino modified, carboxyl modified, alcohol modified, fluorine modified, alkylaralkyl polyether modified, epoxy / polyether modified, polyether modified is desirable. As the release agent, one type or two or more types are used. or,
The amount of the releasing agent added is preferably 0.5 to 30 parts by weight with respect to 100 parts by weight of the resin for forming the dye receiving layer. If the addition amount range is not satisfied, problems such as fusion of the thermal transfer sheet and the dye receiving layer or deterioration of printing sensitivity may occur. By adding such a releasing agent to the dye receiving layer, the releasing agent bleeds out on the surface of the receiving layer after transfer to form a releasing layer.

The receptive layer is prepared by dissolving one of the above-mentioned base sheet (or release layer) and the above resin with necessary additives such as a release agent, dissolved in a suitable organic solvent. Alternatively, it is formed by applying and drying a dispersion dispersed in an organic solvent or water by a forming means such as a gravure printing method, a screen printing method, and a reverse roll coating method using a gravure plate. When forming the dye receiving layer, a filler such as kaolin clay, calcium carbonate, fine powder silica or the like may be added for the purpose of improving foil breakage of the receiving layer. The dye-receptive layer formed as described above may have any thickness, but is generally 1 to 50 μm.
Is the thickness of. Further, such a dye receiving layer is preferably a continuous coating, but it may be formed as a discontinuous coating by using a resin emulsion or resin dispersion.

Further, an intermediate layer 4 may be formed on the surface of the above-mentioned receiving layer. Such an intermediate layer is coated with a solution of a resin having a good coating property such as polyamide resin, acrylic resin, vinyl chloride resin, ethylene / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate copolymer resin, polyester resin, etc. By drying, preferably 0.1
It is formed to a thickness of about 10 μm. By forming such an intermediate layer, it is possible to prevent unevenness and pinholes from occurring in the dye receiving layer due to foaming or expansion of the bubble-containing layer, and further improving the strength and adhesion of the receiving layer. The bubble-containing layer formed on the intermediate layer or the dye receiving layer,
For example, in a coating liquid containing a thermoplastic resin such as a polyurethane resin, an acrylic resin, a polyethylene resin, a butadiene rubber, or an epoxy resin as a binder, bubbles and / or foaming having an average particle diameter of 20 μm or less, preferably 1 to 20 μm. It is formed by applying and drying the one containing the agent. If the average particle size exceeds 20 μm, the above-mentioned various problems occur, and it is difficult to obtain bubbles or foaming agents having an average particle size of less than 1 μm. However, in the case of a solid pyrolyzable foaming agent as described below, it can be used by pulverizing to an average particle size of about 0.1 μm.

The bubble-containing layer may or may not partially expand or foam the bubbles or the foaming agent after the layer is formed. When foaming, the diameter of the foam cells is 40 μm
It is preferable to use a foaming agent having a particle size as shown below. As the foaming agent to be used, a decomposition type foaming agent such as dinitropentamethylenetetramine, diazoaminobenzene, azobisisobutyronitrile, azodicarbonamide, etc. that decomposes by heating to generate gases such as oxygen, carbon dioxide, nitrogen and the like. , Butane, polyvinylidene chloride low-boiling liquids such as pentane, can be used any known foaming agent such as microballoons microcapsulated with a resin such as polyacrylonitrile, further foamed by pre-expanding these microballoons or Microballoons coated with a white pigment can also be effectively used. The amount of the foaming agent or foam used is preferably such that the transferable resin layer has a thickness of about 1.1 to 4 times when heated to 90 ° C to 120 ° C. When the expansion rate (expansion rate) is less than 1.1, it is difficult to achieve the object of the present invention. On the other hand, when the expansion rate (expansion rate) exceeds 4 times, it is difficult to obtain a base material for the image-receiving sheet. It is not preferable because the adhesiveness becomes insufficient. Particularly preferred foaming agents are the microballoons capable of being foamed or expanded at a relatively low temperature, the foams thereof and the microballoons coated with a white pigment.
Various grades are available from Matsumoto Yushi-Seiyaku,
Either can be used in the present invention. The thickness of these bubble-containing layers is preferably about 2 to 20 μm.

In the present invention, it is preferable to further provide an adhesive layer in order to improve the transferability of the above transferable resin layer.
These adhesive layers are formed, for example, by applying and drying a solution of a resin having good adhesiveness at the time of heat such as polyamide resin, acrylic resin, vinyl chloride resin, vinyl chloride / vinyl acetate copolymer resin, polyester resin, etc. The thickness is preferably about 0.5 to 10 μm. It is also possible to incorporate bubbles and / or a foaming agent into these adhesive layers so that they also serve as the bubble-containing layer. Further, in the present invention, by containing a filler, a white pigment, a fluorescent whitening agent and the like in at least one of the above layers, it is possible to provide a receiving layer having excellent whiteness regardless of the background color of the image receiving sheet. I can.

The above example is a basic aspect of the present invention, but in the present invention, as shown in FIG. 2, the transferable resin layer A as described above is provided on a part of the long base film 1. Adjacent to the transferable resin layer, a dye layer composed of a sublimable dye, for example, a yellow Y, a magenta M and a cyan C, and if necessary, a black Bk dye layer is provided in a surface sequential manner, and these dye layers are further provided. And a transferable protective layer (7: peeling layer, 8: protective layer, 9 :) for protecting the surface of the formed image.
It is also possible to provide an adhesive layer). In the case of such a composite thermal transfer sheet, for example, the resin layer A containing the dye receiving layer is first transferred to a necessary area of an image receiving sheet such as a postcard, and the dye layer Y is transferred to the resin layer containing the transferred receiving layer. , M, C to form a dye image, and subsequently transfer the protective layer (8, 9) to the surface of the formed image, and a desired image can be obtained by using one thermal transfer sheet and one thermal transfer printer. Can be formed into

The thermal transfer image-receiving sheet of the present invention is the thermal transfer image-receiving sheet obtained as described above, and a coating liquid for forming each of the adhesive layer, the bubble-containing layer, the intermediate layer and the receiving layer is prepared in addition to the sheet. A thermal transfer image-receiving sheet having the same effects can be obtained by a method in which the above-mentioned image-receiving sheet is used as a base material sheet and these layers are sequentially laminated on the coating solution by a coating method. When foaming the cells or the foam material, it is preferable to use a foaming agent having a particle size such that the particle size of the foam cells is 40 μm or less. The foaming or expansion of the thermal transfer image-receiving sheet of the present invention as described above is preferably performed during or after its production, but may be performed by heat from a thermal head used during image formation.
