Abstract

Abstract Disclosed is an image receiving sheet for thermal transfer recording comprising: a support and an image receiving layer thereon, wherein the image receiving layer comprises an outermost layer being farthest from the support and a layer other than the outermost layer, and a glass transition temperature of a first binder used in the outermost layer is higher than that of a second binder used in the layer adjacent to the outermost layer.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 70 words
An image receiving sheet for thermal transfer recording comprising: a support and an image receiving layer thereon, wherein the image receiving layer comprises an outermost layer being farthest from the support and a layer adjacent to the outermost layer, and the glass transition temperature of a first binder used in the outermost layer is higher than that of a second binder used in the layer adjacent to the outermost layer.
Claim 2
Dependent Claim 70 words
An image receiving sheet for thermal transfer recording comprising: a support and an image receiving layer thereon, wherein the image receiving layer comprises an outermost layer being farthest from the support and a layer adjacent to the outermost layer, and the glass transition temperature of a first binder used in the outermost layer is higher than that of a second binder used in the layer adjacent to the outermost layer.
Claim 3
Dependent Claim 42 words
The sheet of claim 1 wherein the difference between the glass transition temperature of the first binder used in the outermost layer and that of the second binder used in the layer adjacent to the outermost layer is 10° C. or more.
Claim 4
Dependent Claim 24 words
