Example Embodiment

[0057] [Example 1]

[0058] Sandblasting was performed on one surface of a 100 μm resin film (Lumirror S10: Toray Industries, Inc.) to produce a substrate (Ra: 0.9 μm) having an uneven shape. On the uneven surface of the substrate, a release layer composed of the following composition was applied so that the thickness calculated from the coating amount according to formula (1) (hereinafter, all the same) was 0.3 μm Apply the liquid and dry to form a release layer. Next, on the release layer, a protective layer coating liquid composed of the following composition was applied so as to have a thickness of 1.5 μm, and dried to produce a thermal transfer sheet of Example 1.

Abstract

A thermal transfer sheet comprises a base material that has a concave-convex shape on a surface thereof, a mold release layer that is disposed on the surface of the base material which has the concave-convex shape, and a protective layer that is disposed on the mold release layer. The mold release layer does not include particulate matter, includes a resin in which an amino resin and a hydroxyl group-containing resin are three-dimensionally cross-linked, and has a concave-convex shape reflecting the concave-convex shape of the base material on a surface where the protective layer is disposed. Preferably, a thickness of the mold release layer is between 30% and 120% of an arithmetic average roughness (Ra) of the base material. The protective layer and a colored layer are transferred onto an adherend by heating and adhering a surface where the colored layer of the thermal transfer sheet is disposed to the adherend after the colored layer is formed on the protective layer of the thermal transfer sheet. The concave-convex shape can be provided on the surface of the thermally transferred protective layer, and thus the transferred protective layer has excellent matte properties, and it is possible not to impair the texture of the adherend using gloss of the protective layer.

Description

technical field [0001] The present invention relates to a sheet for thermal transfer used when transferring patterns such as patterns or characters to textile products such as cloth, paper or wood, etc., and particularly relates to a sheet that has good releasability during thermal transfer and can be printed after transfer. A thermal transfer sheet with a protective layer formed on the pattern. Background technique [0002] When transferring patterns such as patterns or characters to fabric products such as cloth, paper or wood, etc., the following methods are used: the method of providing a colored layer on the part where the pattern is to be applied directly by screen printing, etc.; After forming a colored layer such as a pattern on a permanent transfer substrate, the method of transferring the colored layer. In particular, in order to easily provide a protective layer for protecting the colored layer on the colored layer, a transfer sheet for transferring the protectiv...
