Description

[Technical Field]

[0001] The present disclosure relates to a receptor layer transfer sheet, a method for manufacturing a skin design sheet, and a skin design sheet. [Background technology]

[0002] Skin design sheets, such as tattoo stickers and skin concealing sheets, are known for application to the skin. Tattoo stickers with various designs printed on them are sold at variety stores, sporting and music event venues, amusement parks, etc., and are used to liven up the atmosphere.

[0003] Skin-concealing sheets are sheets in which a base material is pre-colored with a predetermined color by screen printing or the like, and are used to conceal discolorations such as skin blemishes and blemishes. Users choose one that matches their skin color. For example, a skin-concealing sheet is made up of a release sheet, an adhesive layer, a stretchable base material, and a cover sheet laminated in that order, and is attached to the user's skin by peeling off the release sheet, attaching the adhesive layer to the skin, and then peeling off the cover sheet.

[0004] Users can choose a skin concealing sheet that is closest to their own skin color from the multiple colors available on the market, but the colors of skin concealing sheets on the market are limited, and users can be bothered by the color difference between the skin concealing sheet and their skin, which can leave them dissatisfied.

[0005] It is conceivable to produce a skin-concealing sheet by on-demand printing in a color that matches the user's skin tone. A dye-sublimation thermal transfer printer, which has excellent color reproducibility and gradation, is suitable for printing. Thermal transfer printers heat a thermal transfer sheet and transfer dyes to form an image, so the skin-concealing sheet must be provided with a receiving layer to receive the dye. If a receiving layer is provided on a stretchable substrate in advance, there is a risk that the stretchable substrate may melt, be damaged, or be denatured or deformed by the solvent contained in the coating liquid during the process of applying and drying a coating liquid for the receiving layer on the stretchable substrate. Therefore, it is preferable to transfer the receiving layer onto the stretchable substrate by thermal transfer. [Prior art documents] [Patent documents]

[0013] 1a is a cross-sectional view of a laminated sheet 20 used in the manufacture of a skin-design sheet according to an embodiment of the present disclosure. The laminated sheet 20 is a long strip, and has a release sheet 21, an adhesive layer 22 (first adhesive layer), and an elastic sheet 23 laminated in this order.

[0014] Peel-off sheet Release paper or the like that has been subjected to a silicone release treatment or the like can be used as the release sheet 21. The thickness of the release sheet is preferably about 130 μm or more and 210 μm or less.

[0015] The release sheet preferably has a bending resistance of 150 mg to 2500 mg, more preferably 280 mg to 2100 mg. A bending resistance of 150 mg or more can prevent jamming during image formation in the printer 4, which will be described later. A bending resistance of 2500 mg or less can easily cut the release sheet using a cutter 38 (see FIG. 5) of the printer 4, which will be described later.

[0016] The surface of the release sheet (the surface on which the adhesive layer is provided) preferably has a plurality of recesses (dimples). The planar shape of the recesses is approximately circular with a diameter of approximately 2 mm to 3 mm. The recess occupancy rate on the surface of the release sheet is approximately 3% to 20%. The bottoms of the recesses are curved, and the depth of the deepest part is approximately 1 μm to 17 μm. By forming such recesses on the surface of the release sheet, the peel force between the release sheet and the adhesive layer can be adjusted to an appropriate value. Furthermore, in the image formation process on the laminated sheet using a printer described below, an appropriate printing pressure can be applied, preventing the occurrence of orange peel.

[0017] adhesive layer The adhesive layer 22 is preferably made of a urethane or acrylic adhesive that is less likely to cause rashes or inflammation on the skin. Furthermore, a gel-type adhesive is preferable to ensure close contact with the skin. The thickness of the adhesive layer is, for example, 15 μm or more and 30 μm or less.

[0018] Elastic sheet For example, a urethane sheet can be used as the stretchable sheet 23. The stretchable sheet preferably has an elongation rate of approximately 30% to 100%, more preferably approximately 60%, so that it can follow the expansion and contraction of the skin when attached.

[0019] The elongation percentage of the stretchable sheet is determined by a test method conforming to JIS-K-7127 (1999). The elongation percentage can be calculated using the following formula (1). Elongation (%) = 100 × (L - L0) / L0 Equation (1)

[0020] In formula (1), L is the length at which the stretchable sheet breaks (ruptures) when it is pulled at a speed of 200 mm / min using a tensile tester. L0 in formula (1) is the length of the recorded portion before being pulled by the tensile tester. A Tensilon universal material testing machine or the like can be used as the tensile tester.

[0021] The stretchable sheet also has a permeability of 1000g / (m 2 It is preferable that the material has a moisture permeability of at least 24 hours.

[0022] The thickness of the stretchable sheet is preferably 5 μm or more, more preferably 7 μm or more, to prevent wrinkles during application and to improve workability, and is preferably 30 μm or less to prevent discomfort during application.

[0023] In order to facilitate handling of the laminated sheet 20 in which the release sheet 21, adhesive layer 22, and stretchable sheet 23 are laminated in this order, a processing film 40 may be provided on the stretchable sheet 23, as shown in Fig. 1b. The processing film 40 may be an LDPE film or the like having a thickness of about 30 µm to 60 µm.

[0024] As shown in Figures 2a and 2b, the adhesive layer 22 and stretchable sheet 23 of the laminated sheet 20 are processed into the shape of the product form of the skin-design sheet using a known cutting device. Figure 2a is a cross-sectional view taken along line IIa-IIa in Figure 2b. For example, as shown in Figures 2a and 2b, the adhesive layer 22 and stretchable sheet 23 are processed into a circular shape in plan view. The circular adhesive layer 22 and stretchable sheet 23 are formed at predetermined intervals in the longitudinal direction. The circular adhesive layer 22 and stretchable sheet 23 arranged in the longitudinal direction may be in one row or multiple rows. Figures 2a and 2b show an example of two rows.

[0025] If the process film 40 is provided, it is peeled off from the stretchable sheet 23 when the laminated sheet 20 is set in the cutting device.

[0026] After the adhesive layer 22 and the stretchable sheet 23 have been processed into a product form, a long strip-shaped protective film 24 is attached to the laminate sheet 20, as shown in Figures 3a and 3b. The protective film 24 has a weak adhesive layer 25 (second adhesive layer) provided on one side thereof. The weak adhesive layer 25 is provided in a position that does not contact the adhesive layer 22 or the stretchable sheet 23. For example, in the example shown in Figure 3a, three lines of the weak adhesive layer 25 are provided on one side of the protective film 24, and are attached to the surface of the release sheet 21 at three locations: outside the stretchable sheet 23 (and adhesive layer 22) in the width direction (short direction), and between the stretchable sheets 23, 23.

[0027] An LDPE film or a PP film having a thickness of about 30 μm to 60 μm can be used for the protective film 24. An acrylic or urethane weak adhesive can be used for the weak adhesive layer 25.

[0028] Next, using a known cutting device, a plurality of half cuts 26 extending in the width direction are formed at predetermined intervals in the protective film 24, as shown in Fig. 4. The half cuts 26 are formed at positions between the stretchable sheets 23. For example, the half cuts 26 are formed at positions between the stretchable sheets 23, 23 adjacent in the longitudinal direction.

[0029] The laminated sheet 20 having the half cut 26 formed in the protective film 24 is wound into a roll to produce a laminated sheet roll, which is set in the printer 4 shown in FIG.

[0030] FIG. 5 is a schematic diagram of the printer 4, and FIG. 6 is a cross-sectional view of a thermal transfer sheet 10 used in the printer 4. As shown in FIG.

[0031] The thermal transfer sheet 10 is wound around a supply section 33, and is fed from the supply section 33, passes through the thermal head 31, and is wound around and collected by a collection section .

[0032] The thermal transfer sheet 10 has a transfer mold receiving layer 11, a dye layer D, and a protective layer 15 formed in face order on one surface of a base sheet 16, from the recovery section 34 side. The dye layer D has a yellow dye layer 12, a magenta dye layer 13, and a cyan dye layer 14 formed in face order.

[0033] As described below, a receiving layer 11 is transferred from a thermal transfer sheet 10 onto the elastic sheet 23 of the laminated sheet 20, dye is transferred from the dye layer D to the transferred receiving layer 11 to form an image, and a protective layer 15 is transferred from the thermal transfer sheet 10 onto the image-formed receiving layer 11.

[0034] The material of the base sheet 16 is not particularly limited, and the same base sheet as that used in conventional thermal transfer sheets can be used as is.

[0035] Examples include thin papers such as condenser paper, glassine paper, and wax paper, and films of polyester, polyacrylate, polycarbonate, polyurethane, polyimide, polyetherimide, cellulose derivatives, polyethylene, ethylene-vinyl acetate copolymer, polypropylene, polystyrene, acrylic, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, polyvinyl butyral, nylon, polyether ether ketone, polysulfone, polyethersulfone, tetrafluoroethylene-perfluoroalkyl vinyl ether, polyvinyl fluoride, tetrafluoroethylene-ethylene, tetrafluoroethylene-hexafluoropropylene, polychlorotrifluoroethylene, and polyvinylidene fluoride, and these synthetic resins may also be laminated with the above-mentioned papers.

[0036] The thickness of the base sheet 16 can be changed as appropriate depending on the material so that the strength, heat resistance, etc. are appropriate, and is, for example, about 2 μm or more and 100 μm or less.

[0037] The receiving layer 11 is a transparent layer that receives the dye that migrates from the dye layer D of the thermal transfer sheet 10 after transfer to the transfer-receiving material.

[0038] Resins for forming the receiving layer 11 include, for example, polyolefin resins such as polypropylene, halogenated polymers such as polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, and polyvinylidene chloride, vinyl polymers such as polyvinyl acetate, ethylene-vinyl acetate copolymer, and polyacrylic ester, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polystyrene resins, polyamide resins, copolymer resins of olefins such as ethylene and propylene with other vinyl monomers, ionomers, cellulose resins such as cellulose diacetate, polycarbonate resins, polyvinyl acetal resins, and polyvinyl alcohol resins, with vinyl resins and polyester resins being particularly preferred.

[0039] Receptor layer 11 contains three types of release agents in combination: epoxy-modified silicone, methylstyrene-modified silicone, and polyether-modified silicone.

[0040] The release agents added to the receiving layer are three types: epoxy-modified silicone, methylstyrene-modified silicone, and polyether-modified silicone. By setting the content of the polyether-modified silicone to 1 to 4.5 wt % based on the resin content of the receiving layer, the state of the release agent on the surface of the receiving layer (the state in which the release agent has bled) can be controlled, and the release agent (silicone) can be localized near the peel interface of the receiving layer 11 of the thermal transfer sheet 10, thereby satisfying both the adhesiveness to the transfer recipient (stretchable sheet 23) and the print releasability from the dye layer of the thermal transfer sheet 10. The content of the polyether-modified silicone is more preferably 1.5 to 3.5 wt % based on the resin content of the receiving layer, and even more preferably 1.5 to 2.8 wt %.

[0041] The content of the epoxy-modified silicone in the receiving layer is preferably 2% by weight to 13% by weight, more preferably 2.5% by weight to 5.0% by weight, based on the resin content of the receiving layer.

[0042] The content of the methylstyrene-modified silicone in the receiving layer is preferably 2% by weight to 13% by weight, more preferably 2.5% by weight to 5.0% by weight, based on the resin content of the receiving layer.

[0043] The receiving layer is formed by dissolving a resin in combination with three types of release agents, namely epoxy-modified silicone, methylstyrene-modified silicone, and polyether-modified silicone, and adding additives as necessary, in an appropriate organic solvent, or dispersing the resulting dispersion in an organic solvent or water, and then coating and drying the dispersion using a method such as gravure printing, screen printing, or reverse roll coating using a gravure plate.

[0044] Considering its use as a skin design sheet, the thickness of the receiving layer is preferably 2 μm or less. Also, considering the flexibility of the skin design sheet, it is preferable not to provide an adhesive layer on the receiving layer. In other words, it is preferable to transfer the receiving layer directly onto the elastic sheet 23 of the laminated sheet 20, which will be the transfer target, without using an adhesive layer.

[0045] It is also preferable not to provide a release layer between the base sheet 16 and the receiving layer 11. As mentioned above, when used as a skin design sheet, it is desirable to make the receiving layer extremely thin. If there is a release layer on the base sheet 16, applying a receiving layer coating liquid thereon to form a thin receiving layer may deteriorate the coating suitability.

[0046] The dye layer D (yellow dye layer 12, magenta dye layer 13, cyan dye layer 14) is a layer for transferring dye to the receptor layer 11 transferred onto the stretchable sheet to form an image. There are no particular limitations on the dye layer D, and any of the conventionally known dye layers, i.e., a yellow dye layer, a magenta dye layer, a cyan dye layer, etc., may be appropriately selected and used.

[0047] The dye layer preferably contains a sublimable dye, for example, azomethine dyes such as diarylmethane dyes, triarylmethane dyes, thiazole dyes, merocyanine dyes, pyrazolone dyes, methine dyes, indoaniline dyes, acetophenoneazomethine, pyrazoloazomethine, imidazoleazomethine, imidazoazomethine, and pyridoneazomethine, xanthene dyes, oxazine dyes, and cyanostyrene dyes such as dicyanostyrene and tricyanostyrene. Examples of the dyes include azo dyes such as benzene dyes, thiazine dyes, azine dyes, acridine dyes, benzene azo dyes, pyridone azo, thiophene azo, isothiazole azo, pyrrole azo, pyrazole azo, imidazole azo, thiadiazole azo, triazole azo, and disazo, spiropyran dyes, indolinospiropyran dyes, fluoran dyes, rhodamine lactam dyes, naphthoquinone dyes, anthraquinone dyes, and quinophthalone dyes.

[0048] The dye layer preferably contains a binder resin for supporting the dye, such as a cellulose resin, a vinyl resin, an acrylic resin, a polyurethane, a polyamide, a polyester, or a polyvinyl acetal.

[0049] A transparent resin material can be used for the protective layer 15. Furthermore, the protective layer 15 is preferably matte with low surface reflectance to prevent shine when applied to the skin. Here, "matte" refers to a state with a glossiness of 40% or less. The glossiness is measured using a gloss meter at an incident angle of 45°.

[0050] The laminate sheet 20 is unwound from a laminate sheet roll 36. The laminate sheet roll 36 is manufactured by the method described above and is attached to a reel part (not shown). When the reel part is rotated (forward / reverse), the laminate sheet roll 36 rotates, and the laminate sheet 20 is unwound or wound. The laminate sheet 20 has a high stiffness because the release sheet 21 has a bending resistance of 150 mg or more and a protective film 24 is provided on the elastic sheet 23, ensuring stable transportability within the printer 4.

[0051] In the printer 4, a rotatable platen roll 32 is provided on the opposite side of the thermal head 31 with the thermal transfer sheet 10 sandwiched between them. The thermal head 31 and the platen roll 32 sandwich the laminated sheet 20 and the thermal transfer sheet 10 and heat the thermal transfer sheet 10.

[0052] A conveying guide 35 is provided downstream of the thermal head 31 in the conveying direction of the laminated sheet 20. A cutter 38 is provided downstream of the conveying guide 35 in the conveying direction of the laminated sheet 20 and near the discharge port (not shown) of the printer 4.

[0053] To form an image of a desired color on the stretchable sheet 23 of the laminated sheet 20, it is necessary to peel off the protective film 24. Therefore, before forming the image, as shown in Fig. 7a, the leading end of the laminated sheet 20 is ejected from the printer 4 through the ejection port of the printer 4 to the outside, and in that state, the conveyance of the laminated sheet 20 is temporarily stopped.

[0054] As shown in Fig. 7b, an operator peels off the protective film 24 from the leading end of the laminated sheet 20 and cuts it along the half cut 26. After peeling off the protective film 24, the leading end of the laminated sheet 20 is rewound into the printer 4 as shown in Fig. 7c.

[0055] When the stretchable sheet 23 with its surface exposed reaches the thermal head 31, the thermal head 31 heats the transfer-type receiving layer 11 and transfers the receiving layer 11 onto the stretchable sheet 23 of the laminated sheet 20, as shown in Figures 8a and 8b. The receiving layer 11 is transferred to match the shape of the stretchable sheet 23. Because the receiving layer 11 contains the above three types of modified silicones in the above amounts, it has sufficient adhesion to the stretchable sheet 23.

[0056] Next, the thermal head 31 sequentially heats the yellow dye layer 12, magenta dye layer 13, and cyan dye layer 14 based on the data of the skin design sheet, transferring the dyes to the receiving layer 11 on the image receiving sheet 20 to form the skin design sheet image G. Since the receiving layer 11 contains the above three types of modified silicone in the above amounts, sufficient print releasability is obtained for the dye layer D.

[0057] Next, the protective layer 15 of the thermal transfer sheet 10 is heated, and the protective layer 15 is transferred onto the receiving layer 11 on which the skin design sheet image G is formed, as shown in Figures 9a and 9b. This forms a skin design sheet 5 on the release sheet 21, in which the adhesive layer 22, the stretchable sheet 23, the receiving layer 11 on which the skin design sheet image G is formed, and the protective layer 15 are laminated in this order.

[0058] Thereafter, the cutter 38 cuts the tip of the release sheet 21 in the width direction, cutting out the area where the skin design sheet 5 is provided from the laminated sheet 20, and ejecting it from the printer 4. The cutter 38 only needs to cut the release sheet 21 portion, and the blade does not come into contact with the adhesive layer 22, so it is possible to suppress a decrease in cutting performance with use. In addition, because the bending resistance of the release sheet 21 is 2500 mg or less, it is easy for the cutter 38 to cut the release sheet 21.

[0059] A cover sheet may be attached onto the skin design sheet 5 (protective layer 15) discharged from the printer 4.

[0060] Thus, according to this embodiment, the skin design sheet 5 is produced on demand, so the color of the skin design sheet 5 matches the user's natural skin color, reducing the sense of discomfort when the skin design sheet 5 is applied to the skin and resulting in a natural finish.

[0061] Furthermore, since the receiving layer 11 contains the above three types of modified silicone in the above amounts, the receiving layer 11 can be stably transferred onto the elastic sheet 23 and the desired color can be expressed in the receiving layer 11, allowing for the production of a high-quality skin-design sheet.

[0062] It is preferable that the conveyance guide 35 and guide rollers (not shown) in the printer 4 are made of non-adhesive materials.

[0063] In the above embodiment, the transfer-type receptor layer 11 provided on the thermal transfer sheet 10 used in the printer 4 may be a white receptor layer. The white receptor layer is formed by laminating a transparent receptor layer and a primer layer containing a white pigment such as silica, titanium oxide, titanium dioxide, zinc oxide, cerium oxide, titanium mica, muscovite, white carbon, calcium carbonate, barium sulfate, alumina white, or talc. The use of the white receptor layer suppresses reflected light from the discolored area S of the skin, enhances the concealment of the discolored area S, and improves the reproducibility of the desired skin color. The transparent receptor layer may contain light-scattering particles.

[0064] A hiding layer may be further provided on the white layer (primer layer containing a white pigment) of the white receiving layer. The hiding layer is preferably a metal pigment, such as aluminum, nickel, chromium, brass, tin, brass, bronze, zinc, silver, platinum, gold, and oxides thereof, as well as particles of glass or the like subjected to metal vapor deposition. Among these, aluminum pigments are particularly preferred in terms of the transferability and glossiness of the hiding layer. The aluminum pigment may be either a leafing type or a non-leafing type, but non-leafing types are preferred in terms of the transferability and glossiness of the hiding layer.

[0065] In the above embodiment, an example is described in which the adhesive layer 22 and the stretchable sheet 23 of the laminated sheet 20 are processed into a circular shape in a planar view. However, the processing steps shown in Figures 2a and 2b may be omitted, and the manufactured skin-design sheet may be cut by the user himself or herself to the desired size and shape.

[0066] In the above embodiment, a configuration was described in which a receiving layer 11, a dye layer D, and a protective layer 15 are formed in face-sequential order on a base sheet 16, but a receiving layer transfer sheet in which a receiving layer is provided on a base sheet and a thermal transfer sheet in which a dye layer D and a protective layer 15 are provided on a base sheet may also be formed as separate ribbons. [Example]

[0067] The present disclosure will now be described in more detail with reference to examples, but the present disclosure is not limited to these examples.

[0068] (Preparation of laminated sheets) An acrylic weak adhesive was applied to a release sheet (SLB-110WT, 170 μm thick, manufactured by Sumitomo Kakoshi Co., Ltd.) to form a 30 μm thick adhesive layer. A 15 μm thick urethane film (stretchable sheet) was then attached to the adhesive layer to produce a laminated sheet in which the release sheet, adhesive layer, and stretchable sheet were laminated in that order.

[0069] (Preparation of Receptor Layer Transfer Sheet) A 4.5 μm thick polyethylene terephthalate film (manufactured by Toray) was prepared as a substrate, and a receiving layer coating liquid having the following composition was applied to the surface of this substrate using a bar coater.After pre-drying with a dryer, it was dried in an oven at 100°C for 30 minutes to form a 2 μm thick receiving layer, thereby producing the receiving layer transfer sheet of Example 1.

[0070] [Receptor layer coating liquid composition] Vinyl chloride-vinyl acetate copolymer 100 parts (1000A, manufactured by Denki Kagaku Kogyo Co., Ltd.) Epoxy-modified silicone 3.5 parts (X-22-3000T, manufactured by Shin-Etsu Chemical Co., Ltd.) Methylstyrene-modified silicone 3.5 parts (X-24-510, manufactured by Shin-Etsu Chemical Co., Ltd.) Polyether-modified silicone 2.5 parts (FZ2101, manufactured by Nippon Unicar Co., Ltd.) Methyl ethyl ketone / toluene (weight ratio 1 / 1) 400 parts

[0071] The contents of the epoxy-modified silicone, methylstyrene-modified silicone, and polyether-modified silicone in the coating liquid for the receiving layer of Example 1 were changed to those shown in Table 1, and the rest was done in the same manner as in Example 1 to prepare receiving layer transfer sheets for Examples 2 and 3 and Comparative Examples 1 and 2.

[0072] <<Evaluation of Coatability>> The coating suitability of the receiving layer coating solution applied to the substrate was evaluated by visually observing the condition of the coated surface and based on the following evaluation criteria. The results are shown in Table 1.

[0073] "Evaluation Criteria" A: There are no streaks or unevenness on the coated surface. B: Streaks and unevenness are observed on the coated surface.

[0074] (Transfer of the receiving layer to the laminated sheet) Using the above laminate sheet and the receiving layer transfer sheets prepared in Examples 1 to 3 and Comparative Examples 1 and 2, the receiving layer was transferred from the receiving layer transfer sheet onto the stretchable sheet of the laminate sheet under the following conditions.

[0075] [Transfer conditions] Thermal head: KGT-217-12MPL20 (Kyocera Corporation) Heating element average resistance: 31915 (Ω) Print density in the main scanning direction: 300 dpi Sub-scanning direction print density: 300 dpi ·Applied power: 0.12(w / dot) 1 line period: 5 (msec.) ·Printing start temperature: 40(℃) Applied pulse: A multi-pulse test printer was used that could vary the number of divided pulses, each with a pulse length that divides one line cycle into 256 equal parts, from 0 to 255 during one line cycle. The duty ratio of each divided pulse was fixed at 60%, and the number of pulses per line cycle was fixed at 255.

[0076] <<Evaluation of adhesion between the receiving layer and the stretchable sheet>> For the samples in which the receiving layer was transferred onto the stretchable sheet of the laminated sheet under the above conditions, cellophane tape was used to attach the transferred receiving layer by pressing the tape back and forth with the thumb, and then immediately peeling the tape off by hand at a 180° peel angle. The receiving layer was visually observed to see if it had been taken to the tape side and peeled off, and evaluated according to the following criteria. The results are shown in Table 1.

[0077] "Evaluation Criteria" A: Nothing is taken up by the tape and peels off, and the adhesiveness is good. B: Some of the material was picked up by the tape and peeled off, showing poor adhesion.

[0078] (Printing onto the receiving layer) A thermal transfer sheet (transfer film PK700L for video printer CP-700 manufactured by Mitsubishi Electric Corporation) having a dye layer on a substrate was used to overlay the laminated sheet with the receiving layer transferred onto the elastic sheet, with the dye layer facing the receiving layer. Thermal transfer recording was then performed using a thermal head under the following conditions from the back side of the thermal transfer sheet in the order of Y, M, and C, to form a gray gradation image.

[0079] [Gray gradation image printing conditions] Thermal head: KGT-217-12MPL20 (Kyocera Corporation) Heating element average resistance: 3195 (Ω) Print density in the main scanning direction: 300 dpi Sub-scanning direction print density: 300 dpi ·Applied power: 0.12(w / dot) 1 line period: 5 (msec.) ·Printing start temperature: 40(℃) Gradation control method: A multi-pulse test printer is used that can vary the number of divided pulses, each with a pulse length that divides one line cycle into 256 equal parts, from 0 to 255 during one line cycle. The duty ratio of each divided pulse is fixed at 60%, and the number of pulses per line cycle is increased in steps of 17 from 0 to 255 depending on the gradation, with 0 at 0 step, 17 at 1 step, and 34 at 2 steps, thereby controlling 16 gradations from 0 step to 15 step.

[0080] <<Evaluation of release properties during printing>> When a gradation image was printed on the receiving layer transferred onto the elastic sheet, the releasability between the receiving layer and the dye layer of the thermal transfer sheet (e.g., whether they were difficult to separate, whether they were fused together, etc.) was visually observed and evaluated based on the following evaluation criteria. The results are shown in Table 1.

[0081] "Evaluation Criteria" A: Good releasability. B: No fusion, but severe separation of the two. C: Partial or full fusion, abnormal transfer.
