<< Transfer sheet >>
Hereinafter, a transfer sheet according to an embodiment of the present disclosure (hereinafter referred to as a transfer sheet of the present disclosure) will be described.

  As shown in FIG. 1, the transfer sheet 100 of the present disclosure is provided with a transfer layer 10 on one surface of a substrate 1, and the transfer layer 10 includes a hiding layer 3 and a gloss layer 2 from the substrate 1 side. The laminated structure is formed by laminating in this order. FIG. 1 is a schematic cross-sectional view illustrating an example of a transfer sheet 100 of the present disclosure.

  As shown in FIGS. 11A and 11B, the transfer sheet 100 of the present disclosure manufactures a decorative sheet 250 in which the gloss layer 2 and the concealing layer 3 are laminated in this order on the intermediate medium 200. Transfer sheet. Specifically, the transfer layer 10 of the transfer sheet 100 of the present disclosure is transferred onto the intermediate medium 200, and the gloss layer 2 and the concealing layer 3 are formed on the intermediate medium 200 from the intermediate medium 200 side in this order. This is a transfer sheet for manufacturing a decorative sheet 250 provided with a laminated transfer layer 10. FIG. 11A is a schematic cross-sectional view showing an example of a decorative sheet 250 in which the transfer layer 10 of the transfer sheet 100 of the present disclosure is transferred in a solid shape on the intermediate medium 200, and FIG. b) is a schematic cross-sectional view showing an example of a decorative sheet 250 in which the transfer layer 10 of the transfer sheet 100 of the present disclosure is transferred in a pattern on the intermediate medium 200.

  According to the decorative sheet 250 manufactured using the transfer sheet 100 of the present disclosure, at least the decorative sheet 250 is transferred onto the support member 300 by integrating the decorative sheet 250 and the support member 300. The decorative article 500 provided with the layer 10 can be manufactured. In other words, using the decorative sheet 250 manufactured using the transfer sheet 100 of the present disclosure, a decorative product 500 in which the concealing layer 3 and the gloss layer 2 are laminated in this order on the support member 300 can be manufactured. . More specifically, according to the transfer sheet 100 of the present disclosure, the intermediate medium 200 and the transfer sheet 100 of the present disclosure are overlaid (see FIGS. 6A, 7A, and 8A). Then, by transferring the transfer layer 10 of the transfer sheet 100 of the present disclosure onto the intermediate medium 200, a decorative sheet 250 in which the transfer layer 10 is transferred onto the intermediate medium 200 is obtained (FIG. 6B, FIG. 7 (b) and FIG. 8 (b)). That is, the decorative sheet 250 can be manufactured using the transfer sheet 100 of the present disclosure. Further, by integrating the obtained decorative sheet with the support member 300, a decorative product 500 (FIG. 6C, FIG. 7C) in which at least the transfer layer 10 is provided on the support member 300 is provided. FIG. 8D can be manufactured.

  The transfer sheet 100 according to the present disclosure serves as a primary medium when the decorative product 500 is manufactured, and the decorative sheet 250 manufactured using the transfer sheet 100 according to the present disclosure is used when the decorative product 500 is manufactured. Acts as a secondary medium. That is, the transfer sheet 100 of the present disclosure is a transfer sheet 100 used for manufacturing a decorative sheet and also a transfer sheet used for manufacturing a decorative product 500.

  Here, in the transfer sheet 100 of the present disclosure, the transmission density of any one of yellow, magenta, and cyan of the transfer layer 10 is defined to be 1.2 or more. According to the transfer sheet 100 of the present disclosure, it is possible to manufacture a decorative product 500 having clear glossiness, that is, a decorative product 500 having high design properties. In other words, the decorative sheet 250 capable of producing a decorative product with high design properties is obtained. Hereinafter, the transfer layer 10 transferred onto the intermediate medium 200 using the transfer sheet 100 of the present disclosure may be referred to as a decorative pattern. The transfer layer 10 of the transfer sheet of the present disclosure that is transferred onto the intermediate medium 200 may have a solid shape as shown in FIG. 11A, or a pattern shape as shown in FIG. There may be. The decorative pattern includes both a solid shape and a pattern shape.

  According to the transfer sheet 100 of the present disclosure, by transferring the transfer layer 10 of the transfer sheet onto the intermediate medium 200, the gloss layer 2 and the concealing layer 3 are in the same plane shape on the intermediate medium 200, and It is possible to form a decorative pattern that overlaps accurately without any deviation. That is, it is possible to manufacture a decorative sheet 250 having a decorative pattern in which the gloss layer 2 and the concealing layer 3 have the same planar shape and are accurately overlapped on the intermediate medium 200 without deviation. Moreover, using the decorative sheet 100 manufactured using the transfer sheet 100 of the present disclosure, the decorative pattern in which the concealing layer 3 and the glossy layer 2 have the same planar shape and are accurately overlapped without shifting is provided as a support member. The decorative article 500 provided on 300 can be manufactured.

  In addition, in place of the transfer sheet 100 of the present disclosure having the transfer layer 10 in which the concealing layer 3 and the glossy layer 2 are laminated, a transfer in which the concealing layer 3 and the glossy layer 2 are provided in the surface order on the base material. When a sheet (hereinafter, this transfer sheet is referred to as a comparative transfer sheet), it is difficult to produce a decorative product with high design properties. Specifically, in order to form a decorative pattern on an intermediate medium using a comparative transfer sheet, the concealing layer 3 is transferred onto the intermediate medium, and the gloss layer 2 is formed on the concealing layer 3. It is necessary to accurately stack the images without deviation. However, when the concealing layer 3 and the glossy layer 2 are transferred separately, the concealment layer 3 and the glossy layer 2 are accurately stacked without deviation, in other words, the transfer positions of the concealment layer 3 and the glossy layer 2 are accurately set. Therefore, there is a possibility that a certain shift occurs in the transfer position between the glossy layer 2 and the hiding layer 3. Such a shift in the transfer position between the concealing layer 3 and the glossy layer 2 causes a decrease in the design of the decorative pattern. For example, when the planar shape of the concealing layer 3 and the glossy layer 2 is the same pattern shape, when a shift occurs in the transfer position, the final manufactured decorative product is viewed from the decorative pattern side. Moreover, the concealing layer 3 that does not overlap with the gloss layer 2 can be directly visually recognized, and the design of the manufactured decorative product is low. In addition, when the pattern shape of the hiding layer 3 transferred onto the intermediate medium 200 is made smaller than the pattern shape of the glossy layer 2, it is easy to suppress the hiding layer 3 from being directly recognized. A part of the patterned gloss layer 2 that does not overlap with the concealing layer 3 is generated, and a clear glossiness cannot be imparted to the part. That is, clear glossiness cannot be imparted to the entire surface of the decorative pattern, and the design of the finally manufactured decorative product is low. These problems due to the comparative transfer sheet are particularly remarkable when the decorative pattern is a pattern-like decorative pattern, but even when the decorative pattern is a solid-shaped decorative pattern, These problems are likely to occur near the end.

  In contrast to the comparative transfer sheet, in the transfer sheet 100 of the present disclosure, the transfer layer 10 was transferred onto the intermediate medium 200 in a pattern using the transfer sheet 100 to form a decorative pattern in a pattern. Even if it is a case, the said decoration pattern can be made into the decoration pattern which the glossy layer 2 and the concealment layer 3 were the same pattern, and overlapped correctly without deviation. Thereby, clear glossiness can be provided to the entire surface of the decorative pattern. Moreover, it can also suppress that only the concealment layer 3 is visually recognized directly when the manufactured decorative article 500 is visually recognized from the decorative pattern side. The transfer sheet 100 of the present disclosure can be particularly suitably used when manufacturing a decorative product 500 in which a decorative pattern is provided in a pattern on the support member 300.

  Further, according to the transfer sheet 100 of the present disclosure, it is possible to form a decorative pattern with better interlayer adhesion as compared with the comparative transfer sheet. For example, in the case of a decorative pattern in which the gloss layer 2 and the hiding layer 3 are in direct contact, the adhesion between the gloss layer 2 and the hiding layer 3 can be improved.

  Note that the transfer layer 10 of the transfer sheet 100 of the present disclosure has a laminated structure of the concealing layer 3 and the glossy layer 2 when the transfer layer 10 does not include the concealing layer 3. This is because the transmission density of any of magenta and cyan cannot be 1.2 or more. That is, the concealing layer 3 plays a role of imparting clear gloss to the decorative pattern formed by transferring the transfer layer 10.

  In the preferable form of the transfer sheet 100 of the present disclosure, the transmission density of all of yellow, magenta, and cyan of the transfer layer 10 is 1.2 or more, and more preferably 1.5 or more. In the preferable form of the transfer sheet 100 of the present disclosure, the transfer layer 10 has a transmission density of any one of yellow, magenta, and cyan of 1.5 or more, and more preferably 1.8 or more. According to the transfer layer 10 in a preferred form, it is possible to impart a clearer gloss to the decorative pattern formed by transferring the transfer layer 10, and as a result, the transfer layer 10 is manufactured using the transfer sheet 100 of the present disclosure. The design of the decorative product 500 can be further improved.

  The transmission density of each color of yellow, magenta, and cyan in the transfer layer 10 referred to in the present specification means a transmission density measured by the following method.

(Measurement method of transmission density)
On a transparent polyethylene terephthalate film (as a member to be transferred) having a thickness of 38 μm, a heat roller (Lami Packer 3226 Fuji Pla Co., Ltd.) was used, and 110 ° C., 1.0 m / min. The transfer layer of the target transfer sheet is transferred onto the transfer medium under the heat roll conditions.
A transmission A densitometer (TR-924 X-Rite) was set with a Status A Blue filter, a Green filter, and a Red filter. Using this transmission densitometer, yellow and magenta of the transfer layer provided on the transfer material The transmission density of each color of cyan is measured.
