ができない。Conventionally, there are many types of transfer sheets, and they have been used as a method for easily painting on plastic molded products and the like.
It has been effectively used for many applications over a wide range.
As such a transfer sheet, there is a release sheet in which a transparent release layer, a pattern printing layer, and an adhesive layer are laminated in this order on one surface of a release substrate sheet, but the pattern becomes superficial and flat. Also, in order to express the “shine” of natural wood, the pattern printing layer of the transfer sheet is a wood grain pattern, and the mica ultra-thin flakes whose surface is coated with titanium oxide are dispersed in the adhesive layer ( J. 62-20319). In this transfer sheet, various reflected lights such as those reflected on the surface and those coming out of the surface are mixed, and can realize an effect close to the "shine" of natural wood, but there is "shine" on the whole. Therefore, it has a flat finish, and there is no complicated effect that the luster of natural wood varies depending on the viewing angle. Alternatively, there is a transfer sheet in which a transparent release layer, a pattern printing layer, a wood grain pattern layer made of an ink containing a glitter pigment, and an adhesive layer are laminated in this order on a release substrate sheet, but this is also a surface and an inside. The reflected light mixes well to show a good "shine" effect, but the depth feel of the pattern is poor. In addition, in order to give products a luxurious feeling, some products have a glossy layer formed by vapor deposition of metal or solid printing of an ink containing a brilliant pigment.However, these transfer sheets also have a flat glossy layer. However, only a monotonous appearance can be obtained.
本発明の目的は、光沢があって立体感に富んだ、意匠

してもよい。By printing the white ink pattern layer 4 with a reverse version of the plate on which the pattern print layer 3 is printed, the glossy layer 5 which is not printed with the white ink and is a lower layer in the transparent printed portion of the pattern print layer 3 can be seen through. In the other portions printed with white ink, the lower gloss layer 5 cannot be seen through. Therefore, it is possible to give a depth to a part of the upper pattern printing layer 3, and since the white ink is usually matte, a glossy part and a matte part are generated as a whole, and a sense of visual unevenness is generated. Given. When fine particles are dispersed as an additive in this white ink, the matting effect is further enhanced. This white ink picture layer 4
A known white pigment such as titanium dioxide and zinc oxide, and fine particles such as silica, calcium carbonate, polyethylene wax, and glass beads are mixed in a vehicle obtained by dissolving a binder having good adhesion to the pattern printing layer 3 in a solvent. It is preferable to use an ink in which various additives are dispersed and to provide the ink by a normal printing method such as a gravure printing method or a silk screen printing method. Further, the ratio of additives such as white pigments and fine particles to the vehicle is preferably 40 to 50% in a state of being used for printing, and the ink is easy to use. If the concentration of the solid component is further increased, plate jams are likely to occur during printing, and further problems such as precipitation of the solid component and a decrease in ink layer strength after printing are likely to occur. In addition, you may pay attention to white ink according to the pattern of a pattern printing layer and a white ink pattern layer.
光沢層５は、転写後の絵柄印刷層３及び白インキ絵柄
