Abstract
Abstract A thermal transfer image receiving sheet includes substrate sheet and a dye receptor layer disposed on at least one surface side of the substrate sheet, wherein the dye receptor layer has been formed on the substrate sheet by superposing the substrate sheet onto a receptor layer transfer film comprising a substrate film and the dye receptor layer disposed on one surface side thereof which is peelable from the substrate film, so that the receptor layer transfer film is bonded to the substrate sheet to form a laminate, and peeling the substrate film from the laminate. The thermal transfer sheet also includes a substrate film, an intermediate layer disposed on the substrate film, and a dye layer disposed on the substrate film by the medium of the intermediate layer, wherein the dye layer comprises a dye and a binder resin, and at least one of the intermediate layer and the dye layer contains bubbles.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
60 words
A thermal transfer image receiving sheet comprising a substrate sheet, a cushion layer disposed on at least one surface side of the substrate sheet and a dye receptor layer disposed on the cushion layer, wherein said dye receptor layer contains substantially no filler and has a surface glossiness of 30% or below and said cushion layer contains a foaming agent.
Claim 2
Dependent Claim
60 words
A thermal transfer image receiving sheet comprising a substrate sheet, a cushion layer disposed on at least one surface side of the substrate sheet and a dye receptor layer disposed on the cushion layer, wherein said dye receptor layer contains substantially no filler and has a surface glossiness of 30% or below and said cushion layer contains a foaming agent.
Claim 3
Dependent Claim
39 words
A thermal transfer image receiving sheet according to claim 1 which has been formed by pressing a medium having unevenness onto the surface for the dye receptor layer so as to provide a surface glossiness of 30% or below.
Claim 4
Dependent Claim
90 words
A thermal transfer image receiving sheet according to claim 1, wherein a receptor layer transfer film composed of a substrate film and the dye receptor layer peelable from the substrate film is bonded to the substrate sheet forming a laminate in a condition that the receptor layer transfer film is superposed onto the cushion layer formed on at least one surface side of the substrate sheet and the dye receptor layer is formed on the substrate sheet through the cushion layer by peeling off the substrate film from the laminate.
Claim 5
Dependent Claim
60 words
A thermal transfer image receiving sheet comprising a substrate sheet, a cushion layer disposed on at least one surface side of the substrate sheet and a dye receptor layer disposed on the cushion layer, wherein said dye receptor layer contains substantially no filler and has a surface glossiness of 30% or below and said cushion layer contains a foaming material.
Claim 6
Dependent Claim
60 words
A thermal transfer image receiving sheet comprising a substrate sheet, a cushion layer disposed on at least one surface side of the substrate sheet and a dye receptor layer disposed on the cushion layer, wherein said dye receptor layer contains substantially no filler and has a surface glossiness of 30% or below and said cushion layer contains a foaming material.
Claim 7
Dependent Claim
39 words
A thermal transfer image receiving sheet according to claim 4 which has been formed by pressing a medium having unevenness onto the surface of the dye receptor layer so as to provide a surface glossiness of 30% or below.
Claim 8
Dependent Claim
90 words
A thermal transfer image receiving sheet according to claim 4, wherein a receptor layer transfer film composed of a substrate film and the dye receptor layer peelable from the substrate film is bonded to the substrate sheet forming a laminate in a condition that the receptor layer transfer film is superposed onto the cushion layer formed on at least one surface side of the substrate sheet and the dye receptor layer is formed on the substrate sheet through the cushion layer by peeling off the substrate film from the laminate.
