Abstract

The present invention provides a thermal transfer sheet which can provide a thermal transfer image-receiving sheet capable of forming a printed product of high designability, provides a thermal transfer image-receiving sheet capable of forming a printed product of high designability and a method for forming a printed product, and provides a printed product of high designability.
In a thermal transfer sheet 100 in which a transfer layer 10 is provided on a substrate 1 , the transfer layer 10 has a layered structure in which a receiving layer 2 , an intermediate layer 3 , and a masking layer 4 are layered in this order from the side of the substrate 1 , and the intermediate layer 3 contains inorganic particles.

First claim

The invention claimed is:

1. A thermal transfer image-receiving sheet comprising:
a pattern layer, a masking layer, an intermediate layer, and a first receiving layer provided in this order on a substrate;
wherein a portion of the surface of the pattern layer is exposed,
wherein the intermediate layer contains inorganic particles, and
wherein the pattern layer is a pattern layer in which a hologram layer and a second receiving layer are layered from the top of the substrate.

2. A method for forming a printed product, comprising
preparing a transfer receiving article and a thermal transfer sheet, the transfer receiving article being provided with a pattern layer, the thermal transfer sheet having a thermal transfer layer and a dye layer laminate formed on a same surface of a substrate frame sequentially, the thermal transfer layer comprising a receiving layer, an intermediate layer containing inorganic particles, and a masking layer layered in this order from the surface of the substrate, the dye layer laminate comprising a dye primer layer containing inorganic particles and a dye layer layered in this order from the surface of the substrate;
transferring the transfer layer of the thermal transfer sheet on the pattern layer as being exposed a portion of the surface of the pattern layer externally; and
forming a thermally transferable image on the transfer layer transferred onto the pattern layer by using the dye layer included in the dye layer laminate of the thermal transfer sheet.

3. A thermal transfer image-receiving sheet comprising;
a pattern layer, a masking layer, an intermediate layer, and a first receiving layer provided in this order on a substrate;
wherein a portion of the surface of the pattern layer is exposed,
wherein the intermediate layer contains inorganic particles,
wherein the inorganic particles are inorganic particles derived from colloidal inorganic particles, and
wherein the pattern layer is a pattern layer in which a hologram layer and a second receiving layer are layered from the top of the substrate.

4. A printed product comprising:
a thermally transferable image formed on a first receiving layer of a thermal transfer image-receiving sheet,
wherein the thermal transfer image-receiving sheet comprises a pattern layer, a masking layer, an intermediate layer, and a first receiving layer provided in this order on a substrate,
wherein a portion of the surface of the pattern layer is exposed,
wherein the intermediate layer contains inorganic particles, and
wherein the pattern layer is a pattern layer in which a hologram layer and a second receiving layer are layered from the top of the substrate.
