Abstract

Abstract Disclosed is a thermal transfer image receiving sheet comprising a substrate sheet, an intermediate layer provided on at least one surface side of the substrate sheet and a dye receptor layer provided on the surface of the intermediate layer, wherein the substrate sheet is a pulp paper, the intermediate layer is formed from an organic solvent solution of a resin, and the dye receptor layer is formed from an aqueous resin liquid. By virtue of this structure, the thermal transfer image receiving sheet can be prevented from occurrence of curling caused by temperature change. Also disclosed is a thermal transfer image receiving sheet comprising a substrate sheet, an intermediate layer provided on at least one surface side of the substrate sheet and a dye receptor layer provided on the surface of the intermediate layer, wherein the intermediate layer is formed from either an acrylic resin or a resin at least a part of which is crosslinked. By virtue of this structure, the thermal transfer image receiving sheet can be excellent in smoothness, strength, cushioning properties and writing properties, and further can give an image of high density and high resolution.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 57 words
A thermal transfer image receiving sheet comprising: a substrate sheet; a bubble-containing layer provided on at least one side surface of the substrate sheet containing bubbles formed by foaming microcapsules and an adhesive; an intermediate layer coated on a surface of the bubble-containing layer; and a dye receptor layer provided on a surface of the intermediate layer.
Claim 2
Dependent Claim 57 words
A thermal transfer image receiving sheet comprising: a substrate sheet; a bubble-containing layer provided on at least one side surface of the substrate sheet containing bubbles formed by foaming microcapsules and an adhesive; an intermediate layer coated on a surface of the bubble-containing layer; and a dye receptor layer provided on a surface of the intermediate layer.
Claim 3
Dependent Claim 25 words
A thermal transfer image receiving sheet according to claim 1, wherein said microcapsules are prepared by encapsulating butane or pentane with polyvinylidene chloride or polyacrylonitrile.
