Description

  The present invention provides an intermediate transfer recording medium capable of realizing a desired mat pattern having various surface shapes such as a mat pattern having uneven surfaces, and a printed matter using the intermediate transfer recording medium. The present invention relates to a method of forming, and further to a print obtained by the forming method.

  Conventionally, a thermal transfer method has been widely used as a simple printing method. In the thermal transfer method, a thermal transfer sheet provided with a color material layer on one side of a base sheet and a thermal transfer image receiving sheet provided with an image receiving layer as necessary are superposed, and the thermal transfer sheet is heated by a heating means such as a thermal head. In this method, an image is formed on a thermal transfer image receiving sheet by heating the back surface of the sheet to an image and selectively transferring the color material contained in the color material layer.

  Thermal transfer methods are classified into a melt transfer method and a sublimation transfer method. The melt transfer method uses a thermal transfer sheet in which a color sheet such as a pigment is dispersed in a binder such as a heat-meltable wax or resin and a heat-meltable ink layer is supported on a base sheet such as a PET film, In this image forming method, energy corresponding to image information is applied to a heating means, and a color material is transferred together with a binder onto a thermal transfer image receiving sheet such as paper or a plastic sheet. An image obtained by the melt transfer method has a high density and excellent sharpness, and is suitable for recording binary images such as characters.

  On the other hand, the sublimation transfer method uses a thermal transfer sheet in which a dye layer in which a dye that transfers heat by sublimation is dissolved or dispersed in a resin binder is supported on a base sheet such as a PET film, and is used as a heating means such as a thermal head. In this image forming method, energy is applied in accordance with image information, and only the dye is transferred onto a thermal transfer image receiving sheet in which a dye receiving layer is provided on a base sheet such as paper or plastic as necessary. In the sublimation transfer method, the amount of dye transfer can be controlled in accordance with the amount of energy applied, so that it is possible to form a gradation image in which the image density is controlled for each dot of the thermal head. Further, since the color material to be used is a dye, the formed image is transparent, and the reproducibility of intermediate colors when dyes of different colors are superimposed is excellent. Therefore, when using a thermal transfer sheet having dye layers of different colors such as yellow, magenta, cyan, black, etc., and transferring each color dye on the thermal transfer image receiving sheet, the image quality is excellent with excellent reproducibility of intermediate colors. A photographic full-color image can be formed.

  Specific uses of the thermal transfer image receiving sheet by such a thermal transfer method are various. Typical examples include print proofs, image output, CAD / CAM and other design and design output, various medical analytical instruments such as CT scans and endoscope cameras, and measurement instrument output applications, and As an alternative to instant photos, as well as outputting face photos to ID cards, ID cards, credit cards, and other cards, as well as composite photos and commemorative photos at amusement facilities such as amusement parks, game centers, museums, and aquariums Applications and sign applications (outdoor signboards) can be listed. With the diversification of applications as described above, the demand for forming a thermal transfer image on an arbitrary object has increased, and as one of the countermeasures, as shown in Patent Document 1, the receiving layer can be peeled off on the substrate. Using an intermediate transfer recording medium provided on the thermal transfer sheet having a dye layer or a heat-meltable ink layer as the receiving layer, a colorant such as a dye or pigment is transferred to form an image, and then an intermediate transfer is performed. A method has been proposed in which a recording medium is heated to transfer a receiving layer onto a transfer medium.

  In addition, there is a demand to obtain a mat-like print having a surface with high glossiness and a fine unevenness on the surface of a print having a heat transfer image formed on a heat transfer image-receiving sheet. In contrast, there are the following three methods. (1) As a specification of media, there is a method of creating a protective layer having surface irregularities. For example, as described in Patent Document 2, in a protective layer thermal transfer sheet in which a release layer and a protective layer are laminated on a base material, the release layer contains filler (particles), and the surface of the release layer is The surface of the protective layer is roughened, and the protective layer is thermally transferred onto the image (the release layer remains on the substrate side) to make the surface of the protective layer uneven. In addition, there is a protective layer thermal transfer sheet in which a release layer and a protective layer are laminated on a base material, in which foamable particles are contained in the release layer, and the release layer and the protective layer are transferred onto the image. Furthermore, in the protective layer thermal transfer sheet provided with a protective layer on the substrate, when the protective layer itself was provided on the substrate, a printing plate cylinder having irregularities on the surface was used to have this uneven shape. The protective layer is printed on the base material, and the protective layer is unevenly transferred on the image by thermally transferring the protective layer. In the method for producing a protective layer having surface irregularities as described above, it is difficult to stably form surface irregularities as a method for obtaining a desired mat pattern having various surface shapes. Further, the load for matching the transfer position of the protective layer with the position of the thermal transfer image formed on the printed material is high.

  In addition, as a method of obtaining a mat-like printed matter on the surface, (2) using a protective layer thermal transfer sheet, the strength of the thermal energy at the time of thermal transfer of the protective layer on the image is increased and the surface gloss of the protective layer is increased. There are ways to change. In this method, for example, as disclosed in Patent Document 3, in a protective layer transfer sheet in which a thermal transfer protective layer and an adhesive layer are sequentially laminated on a substrate, the protective layer is composed of a thermoplastic resin and an inorganic layered compound. In the method of forming a protective layer by thermal transfer using the protective layer transfer sheet on the image on the body, the amount of surface gloss of the protective layer can be varied by varying and controlling the amount of heating during thermal transfer. Are listed. In the method (2) for producing a protective layer having surface irregularities, a desired mat pattern having irregularities cannot be obtained stably.

In addition, as a method of obtaining a mat-like print on the surface, (3) a method of matting the surface of the print by pressing a roller or a plate having irregularities on the surface after the print is formed is assumed. . However, even with this method, the present situation is that a desired mat pattern having various surface shapes cannot be realized. Moreover, in order to make it into a mat, the process of pressing a roller, a board, etc. which has an unevenness | corrugation on the surface is required, and a manufacturing cost will be expensive.

Hereinafter, each layer constituting the intermediate transfer recording medium of the present invention will be described in detail.
(Base film)
As the base film 2, the same base film as that used for the conventional intermediate transfer recording medium can be used as it is, and it is not particularly limited. Specific examples of the preferable base film 2 include thin paper such as glassine paper, condenser paper or paraffin paper, or heat resistance such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polyphenylene sulfide, polyether ketone or polyether sulfone. Examples thereof include stretched or unstretched films of plastics such as polyester, polypropylene, polycarbonate, cellulose acetate, polyethylene derivatives, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyamide, polyimide, polymethylpentene, and ionomer. Moreover, the composite film which laminated | stacked 2 or more types of these materials can also be used. The thickness of the base film 2 can be appropriately selected depending on the material so that the strength, heat resistance and the like are appropriate, but usually a thickness of about 1 to 100 μm is preferably used. If necessary, a back layer can be provided on a surface opposite to the release layer side (transfer portion side) provided on the base film by a conventionally known method. In order to improve the slidability and prevent the back layer from fusing between the base film and a heating device such as a thermal head when the transfer portion is transferred to the transfer medium using an intermediate transfer recording medium, It can be provided by the same resin as that used.

(Release layer)
The release layer 3 in the intermediate transfer recording medium of the present invention is formed on the above base film mainly composed of a filler having an average particle size of 0.5 to 5 μm and a curable binder resin. The release layer is made of a filler having an average particle size of 0.5 to 5 μm and a curable binder resin, so that the surface in contact with the protective layer is roughened. The curable binder resin in the release layer can be selected from a thermosetting resin, a photocurable resin, and an electron beam curable resin. As a thermosetting resin, what is generally known as resin which hardens | cures (insolubilizes) when heated can be applied. Examples include phenol-formaldehyde resin, urea-formaldehyde resin, melamine-formaldehyde resin, resin obtained by curing acrylic polyol with isocyanate, resin obtained by curing polyester polyol with melamine, and resin obtained by curing acrylic acid with melamine. It is done. Moreover, you may use combining the monomer which is a structural component of a thermosetting resin.

  In addition to the above, any thermoplastic resin that is cured by crosslinking and has heat resistance can be used as the thermosetting resin. As such a thermosetting resin, for example, a thermosetting acrylic resin is preferably used. The thermosetting acrylic resin is obtained by crosslinking at least one acrylic monomer or a copolymer obtained by polymerizing an acrylic monomer and a styrene monomer with a melamine compound or an isocyanate compound. It is a thing.

  Examples of the acrylic monomers include alkyl methacrylates such as methyl methacrylate, butyl methacrylate, octyl methacrylate, stearyl methacrylate; ethyl acrylate, propyl acrylate, butyl acrylate, octyl acrylate, and the like. Acrylonitrile; amino group-containing vinyl monomers such as acrylamide, dimethylaminoethyl methacrylate, diethylaminoethyl methacrylate, dimethylaminoethyl acrylate, dimethylaminopropyl methacrylamide, etc. In addition, as the styrene monomer, styrene, α-methylstyrene, vinyltoluene, p-ethylstyrene, or the like can be used.

  Examples of the composition using the photocurable resin of the above curable binder resin include, for example, a compound having a reactive double bond such as a vinyl group in a molecule (not only a low molecular weight substance but also a polymer). And an initiator necessary for photocuring are included as main components. Moreover, as a composition using the electron beam curable resin of the curable binder resin, for example, a compound having a reactive double bond such as a vinyl group in the molecule, and a resin as necessary, as a main component. To do. Examples of the compound having a reactive double bond in the molecule include a (meth) acryloyl group, such as methyl (meth) acrylate, ethyl (meth) acrylate, benzyl (meth) acrylate, and 2-ethoxyethyl (meth). Monofunctional type such as acrylate, phenoxydiethylene glycol (meth) acrylate, 1,6-hexanediol di (meth) acrylate, neopentyl glycol di (meth) acrylate, polyethylene glycol di (meth) acrylate, polypropylene glycol di (meth) Acrylate, trimethylpropane tri (meth) acrylate, pentaerythritol tri (meth) acrylate, pentaerythritol tetra (meth) acrylate, dipentaerythritol hexa (meth) acrylate, etc. There is a functional type. There are also oligomers such as polyester acrylate, polyurethane acrylate, polyepoxy acrylate, polyether acrylate, oligo acrylate, polyalkyd acrylate, polyol acrylate and the like. Furthermore, there are, for example, styrene monomer, α-methylstyrene, divinylbenzene, vinyl acetate, pentene, hexene and unsaturated compounds having a vinyl group or an allyl group.

  The photocuring polymerization initiator is added particularly when curing with ultraviolet rays. This photocuring polymerization initiator is usually referred to as a photoinitiator. For example, benzoin alkyl ether, acetophenone, benzophenone, and thioxanthone photoinitiators are preferably used. Examples of the benzoin ether series include benzyl, benzoin, benzoin methyl ether, benzoin ethyl ether, and benzoin propyl ether. Examples of the acetophenone series include 2,2'-diethoxyacetophenone, 2-hydroxy-2-methylpropiophenone, p-ter-butyltrichloroacetophenone, 2,4,6-trimethylbenzoyldiphenylphosphine oxide. Examples of the benzophenone series include benzophenone, 4-chlorobenzophenone, 4,4'-dichlorobenzophenone, 3,3'-dimethyl-4-methoxybenzophenone, dibenzosuberenone and the like. Examples of the thioxanthone series include thioxanthone, 2-chlorothioxanthone, 2-methylthioxanthone, 2-isopropylthioxanthone, and 2-ethylanthraquinone. The said photoinitiator is added in 0.05-10 mass parts with respect to 100 mass parts of compounds which have the said reactive double bond, Preferably it is 0.1-5 mass parts. Moreover, a photoinitiator is not restricted to 1 type, You may use 2 or more types together.

  By using the thermosetting resin, photocurable resin, or electron beam curable resin curable binder resin in the release layer, the filler having an average particle size of 0.5 to 5 μm is firmly supported. The film of the release layer is strong, and the adhesion between the base film and the release layer can be increased. This is because when the transfer portion of the intermediate transfer recording medium is transferred to the transfer target, the release layer is firmly adhered to the base film, so that the release layer is a part of the filler constituting the release layer. However, there is no transfer from the substrate film to the transfer target. As a result, a desired mat pattern can be reproduced on the surface of the printed matter formed by transferring the transfer portion of the intermediate transfer recording medium, and a fine uneven shape on the surface is stably formed, and uneven portions are not formed. Does not occur.

  If the average particle diameter is 0.5-5 micrometers, the filler contained in a mold release layer can use an organic filler or an inorganic filler. Examples of the inorganic filler include fillers such as silica, alumina, clay, talc, diatomaceous earth, zeolite, calcium carbonate, barium sulfate, zinc oxide, titanium oxide, and glass beads. Examples of the organic filler include various synthetic resin particles such as melamine resin, benzoguanamine resin, benzoguanamine / melamine / formalin condensate, acrylic resin, urethane resin, styrene resin, and the like. It can also be used as a mixture. In particular, the melamine and formaldehyde condensates and the organic fillers of benzoguanamine and formaldehyde condensates have excellent matting and anti-reflective effects on the surface of printed materials, or the stability of ink during coating. From the point of view, it is preferable. The shape of the filler may be either a spherical product or a pulverized product. However, the use of a spherical product is preferable because the friction coefficient is lowered and the scratch resistance is improved.

  In this invention, although the magnitude | size of the filler contained in a mold release layer prescribes | regulates that an average particle diameter is 0.5-5 micrometers, this filler is 50 of all the fillers calculated | required by the light transmission type centrifugal sedimentation method. In the present invention, the average particle diameter is defined as the “equivalent spherical diameter” of the filler at the mass% point. If the average particle size is smaller than 0.5 μm, sufficient fine irregularities cannot be provided on the surface of the printed material, resulting in poor matteness and antireflection on the surface of the printed material, and mean particle size of 5 μm. If it is larger than that, it is necessary to add a large amount of filler in order to obtain a sufficient matte feeling. In this case, it becomes difficult to peel off at the interface with the protective layer.

  The filler is preferably contained in an amount of 30 to 150 parts (solid content) with respect to 100 parts (solid content) of the curable binder resin. If the content of the filler is too small, an appropriate fine uneven shape cannot be formed on the surface of the release layer. On the other hand, when there is too much content rate of a filler, the film | membrane intensity | strength of a mold release layer will fall and a problem will arise in peeling with a protective layer. For the release layer, if necessary, an additive is added to the filler having an average particle size of 0.5 to 5 μm and the curable binder resin, and the release layer is dissolved or dispersed in an appropriate solvent to obtain a release layer coating. A working solution is prepared, and this can be formed on a substrate film by applying and drying it by means of a gravure printing method, a screen printing method or a reverse coating method using a gravure plate. The thickness after the drying is about 0.3 to 10 μm. However, the thickness of the release layer is the thickness of the film portion of the binder resin that does not include the filler protrusion.

(Protective layer)
The protective layer 4 in the intermediate transfer recording medium of the present invention is adjacent to the release layer and is configured as a part of the transfer portion of the intermediate transfer recording medium. After the thermal transfer image is formed on the receiving layer, this protective layer is peeled off from the release layer of the intermediate transfer recording medium, transferred onto the transfer material, and positioned on the outermost surface of the image-formed print. In the present invention, the transfer portion of the intermediate transfer recording medium is transferred to the transfer medium, and the surface of the transfer portion is roughened. That is, the surface of the protective layer is roughened in the printed material to which the transfer portion has been transferred. This is because, as shown in 3) of FIG. 2, the surface of the release layer 3 in contact with the protective layer 4 is roughened, so that the release layer 6 is transferred to the transfer body 7 when the transfer portion 6 is transferred. The surface of the protective layer 4 having a symmetric shape with the concavo-convex shape of the surface 3 can be reproduced, that is, the corresponding protective layer 4 becomes a convex portion with respect to the concave portion of the release layer 3, This is because the corresponding protective layer 4 becomes a concave portion, and the protective layer 4 is peeled off together with the receiving layer 5 from the intermediate transfer recording medium 1 and transferred to the transfer target 7.

  The protective layer can be mainly composed of a thermoplastic resin. Examples of the thermoplastic resin include acrylic resins such as polymethyl methacrylate, polyethyl methacrylate, and polybutyl acrylate, polyvinyl acetate, vinyl chloride-vinyl acetate copolymer, vinyl alcohol such as polyvinyl alcohol, and polyvinyl butyral. Resin, cellulose derivatives such as ethyl cellulose, nitrocellulose and cellulose acetate, polyester resins, polyurethane resins, amino alkyd resins and the like can be used. In order to protect the thermal transfer image formed on the receiving layer as a printed matter, the protective layer has excellent durability such as scratch resistance and water resistance. Among the thermoplastic resins described above, an acrylic resin is particularly preferable. Preferably used.

  As the thermoplastic resin constituting the protective layer, those having a glass transition temperature of 80 to 120 ° C. are preferably used. Moreover, said thermoplastic resin can be used individually or in mixture. If the glass transition temperature is less than 80 ° C., bleeding of the thermal transfer image tends to occur when the printed matter is stored at a high temperature. Further, when a thermoplastic resin having a glass transition temperature exceeding 120 ° C. is used, it is necessary to increase the heating temperature of the thermal transfer when transferring the transfer portion on which the image is formed on the intermediate transfer recording medium to the transfer target, Thermal damage to the transferred material is high, and troubles such as curling of the transferred material tend to occur. The protective layer may be added to the above thermoplastic resin, if necessary, by adding additives such as conventionally known ultraviolet absorbers and fluorescent brightening agents to an extent that does not hinder the transparency of the protective layer. To prepare a coating solution for the protective layer by dissolving or dispersing, and applying this onto the release layer of the base film by means of a gravure printing method, a screen printing method or a reverse coating method using a gravure plate Can be formed by drying. The thickness after the drying is usually 0.1 to 10 μm.

(Receptive layer)
The receiving layer 5 used in the intermediate transfer recording medium of the present invention is generally composed mainly of a thermoplastic resin. Examples of the material for forming the receiving layer include polyolefin resins such as polypropylene, vinyl chloride / vinyl acetate copolymer resins, ethylene / vinyl acetate copolymer resins, halogenated polymers such as polyvinylidene chloride resins, and polyvinyl acetate. Resins, polyester resins such as polyacrylic ester resins, polystyrene resins, polyamide resins, copolymer resins of olefin resins such as ethylene and propylene and other vinyl monomers, cellulose resins such as ionomers and cellulose diacetate, Polycarbonate resins, polyvinyl acetal resins, polyvinyl butyral resins and the like can be mentioned, among which polyester resins, vinyl chloride / vinyl acetate copolymers, and mixtures thereof are particularly preferable. Among them, for example, a resin having good adhesiveness during heating such as a polyamide resin, a vinyl chloride / vinyl acetate copolymer resin, and a polyester resin is preferable.

  In the sublimation transfer recording, a release agent can be mixed in the receiving layer for the purpose of preventing fusion with the receiving layer or a decrease in printing sensitivity during image formation. Preferable release agents used in combination include silicone oil, phosphate ester surfactants, fluorine surfactants, and the like, among which silicone oil is desirable. As the silicone oil, modified silicone oils such as epoxy modification, vinyl modification, alkyl modification, amino modification, carboxyl modification, alcohol modification, fluorine modification, alkylaralkyl polyether modification, epoxy / polyether modification, and polyether modification are desirable.

  One or more release agents are used. Moreover, the addition amount of the release agent is preferably 0.5 to 30 parts by mass with respect to 100 parts by mass of the receiving layer forming resin. When the range of the addition amount is not satisfied, problems such as fusion between the sublimation type thermal transfer sheet and the receiving layer of the thermal transfer image receiving sheet or a decrease in printing sensitivity may occur. By adding such a releasing agent to the receiving layer, the releasing agent bleeds out on the surface of the receiving layer after the transfer to form a releasing layer. Further, these release agents may not be added to the receiving layer but may be separately applied on the receiving layer. The receptor layer is a dispersion in which a resin obtained by adding a necessary additive such as a release agent to the above-mentioned protective layer on a base film is dissolved in an appropriate organic solvent or dispersed in an organic solvent or water. Is formed by coating and drying by an appropriate coating method. In forming the receiving layer, a white pigment, a fluorescent brightening agent, or the like can be added for the purpose of improving the whiteness of the receiving layer and further enhancing the sharpness of the transferred image. The receiving layer formed as described above may have any thickness, but generally has a thickness of 1 to 50 μm in a dry state.

Between the heating device and the platen roll so that the transfer portion of the intermediate transfer recording medium and the color material transfer layer of the thermal transfer sheet are in contact with each other, and the heat generating portion of the heating device is selectively heated according to the image information Then, the color material of the color material transfer layer on the thermal transfer sheet is transferred to the receiving layer of the intermediate transfer recording medium, thereby recording an image. A conventionally well-known thing can be used for a thermal transfer sheet. The color material transfer layer provided on the thermal transfer sheet is formed of a heat-meltable ink or an ink containing a sublimation dye. The color material transfer layer is appropriately selected from a heat-meltable ink and a sublimation dye ink according to the target print product. The color material transfer layer composed of a sublimation dye used to obtain a printed matter with excellent gradation is used by appropriately applying each sublimation dye such as yellow, magenta, cyan, and black as necessary. They can be provided sequentially. For single-color binary images such as letters and numbers, a heat transfer sheet provided with a color material transfer layer with a heat-meltable ink excellent in density and sharpness, or a color material transfer made of the above sublimation dye A heat-meltable ink layer can be provided in the surface order with the layer and used.

  As described above, a thermal transfer image is formed on the transfer portion of the intermediate transfer recording medium as a chest image (not as an image on the final print product, but as an image that looks in the mirror), and then the thermal transfer The transfer part on which the image is formed is pressed against the image surface of the transfer part and the transfer target, and the transfer part is applied to the transfer target with a heating means such as a thermal head, a hot stamp, or a heat roll. Transcript. As for the heating means of the transfer section, it is desirable to use a thermal head or hot stamp means for partial transfer, and when transferring to the entire surface of the transfer target, a hot roll method is desirable. As a result, a receiving layer and a protective layer are laminated so as to cover the thermal transfer image on the transfer object, and a printed matter in which the surface of the transferred transfer portion, that is, the surface of the protective layer is roughened is obtained. (See Figure 2)

  In the method for forming a printed material of the present invention, the transfer portion on which the thermal transfer image of the intermediate transfer recording medium is formed and the transfer target are overlapped and heated, and the transfer portion of the intermediate transfer recording medium is transferred onto the transfer target. In order to reliably reproduce the surface of the protective layer that is symmetrical to the uneven shape of the surface of the release layer under the heat transfer conditions when performing, about 10 ° C. than the glass transition temperature of the thermoplastic resin constituting the protective layer It is preferable to set the heating conditions of the thermal head, the hot stamp, and the hot roll so that the heating surface has a higher temperature.

  A print was formed under the following conditions. Using a thermal printer, a thermal transfer sheet provided with a colored layer was transferred onto the receiving layers of the intermediate transfer recording media of the examples and comparative examples prepared above to form an image. And the transfer part which consists of a receiving layer containing the thermal transfer image obtained above, and a protective layer was heat-transferred on the polycarbonate with the heat roller, and each printed matter was produced. However, the surface temperature of the heat roller when the transfer portion was transferred to the transfer target was 195 ° C.

Using the intermediate transfer recording media of the above-mentioned examples and comparative examples, the glossiness measurement and surface appearance evaluation were performed under the following conditions in the prints corresponding to the examples and comparative examples obtained by the above-described methods. It was done.
(Glossiness measurement method)
The glossiness of each print having the thermal transfer image and the protective layer (having the concavo-convex shape) was measured under the following conditions. In accordance with JIS Z 8741 and JIS P 8142, the glossiness was measured at an incident angle of 75 ° by Nippon Denshoku Industries Co., Ltd., Gloss Meter VG2000.

(Surface appearance)
The surface appearance of each printed material on which the thermal transfer image and the protective layer were formed was visually examined and evaluated according to the following criteria.
A: Appearance is embossed and non-glossy, has a desired mat pattern, has a high anti-reflection effect, and is very beautiful.
○: From the appearance, the embossed state and non-glossiness have a desired mat pattern and are beautiful, but the antireflection effect is slightly lowered or the mat pattern is slightly conspicuous.
Δ: From the appearance, the embossed state and non-glossiness are not recognized as the desired mat pattern, and the antireflection effect is low or the mat pattern is conspicuous, which is not preferable.
X: In terms of appearance, the embossed state and non-glossiness are not recognized as a desired mat pattern and have no antireflection effect.

(Printability)
Using the thermal printer described above, the printability when forming a thermal transfer image using a thermal transfer sheet provided with a colored layer on the receiving layer of the intermediate transfer recording medium of each Example and Comparative Example is determined according to the following criteria. evaluated.
Good: Transferability is good when printing a thermal transfer image on the receiving layer of the intermediate transfer recording medium.
X: Transferability is poor in printing a thermal transfer image on the receiving layer of the intermediate transfer recording medium

(Ink stability)
The stability over time of the release layer coating liquid (ink) was evaluated according to the following criteria.
◯: During the coating of the release layer, the release layer coating solution is good because no sediment is observed at the bottom of the ink pan.
Δ: During the coating of the release layer, a slight amount of sediment was observed at the bottom of the ink pan in the release layer coating solution.

Table 1 shows the measurement results of the above glossiness and the evaluation results of the surface appearance, printability and ink stability.

  As described above, in the printed materials of Examples 1, 2, 4, and 5, the glossiness measured at an incident angle of 75 ° on the surface of the printed material is all within the range of 10 to 50%, and the appearance is in an embossed state. With respect to non-glossiness, it has a desired mat pattern and is very beautiful. The printed matter of Example 7 also has a desired mat pattern for appearance, embossed state, and non-glossiness, but the ink stability during coating is poor and the filler tends to settle to the bottom. is there. The printed material of Example 3 has a slightly lower glossiness because of a higher filler content in the release layer. Since the printed matter of Example 6 has a small filler content in the release layer, the glossiness is slightly higher and the antireflection effect is slightly reduced in appearance. Moreover, since the printed matter of Example 8 has a small filler content in the release layer, the glossiness is slightly higher at 45%, and the antireflection effect is slightly reduced in appearance. In addition, since the printed matter of Example 9 has a higher filler content in the release layer, the glossiness is 15%, which is slightly lower. On the other hand, in the printed matter of Comparative Example 1, a part of the release layer was transferred to the transfer medium during transfer, and the effect of the release layer was not obtained. Therefore, glossiness and surface appearance could not be evaluated. In addition, the printed material of Comparative Example 2 has a high average glossiness because the filler contained in the release layer is too small, and the appearance is embossed and non-glossy. It is not something that can be done. In the prints of Comparative Examples 3 and 4, the average particle size of the filler contained in the release layer is too large, the transferability of the thermal transfer sheet to the receiving layer of the colored layer during printing is poor, and the interface with the protective layer It was difficult to peel off. Further, in the printed matter of Comparative Example 5, since there is no filler in the release layer, the glossiness is very high, and no mat pattern is recognized on the surface of the protective layer.
