The image receiving sheet according to the present invention is an image receiving sheet which receives dye migrated by heat from a heat transfer sheet, wherein the image receiving sheet includes a substrate (3), a dye receiving layer (3) provided on one surface of the substrate and a curl prevention layer. The curl prevention layer includes a non-heat stretchable and shrinkable resin having a heating stretching or shrinking ratio within the range from -1.0 to 1.5% in JIS-K-6734 provided on the surface of the substrate on the side opposite to the above dye receiving layer, or between the substrate and the dye receiving layer. In the present invention, by having such a curl prevention layer as mentioned above, generation of curl by heat during image formation can be prevented to provide an image receiving sheet excellent in both conveyability of sheet and printing quality.
An image receiving sheet for receiving dye migrated by heat from a heat transfer sheet, comprising a substrate, a dye receiving layer provided on one surface of said substrate, and a curl prevention layer provided on the surface of the substrate opposite to the dye receiving layer, said curl prevention layer comprising (i) a resin that is non-heat shrinkable and stretchable, and has a heating shrinkage or stretchability measured by JIS-K-6734 within a range of from -1.0 to 1.5%, and (ii) a filler which makes the curl prevention layer slippery, said filler having a particle size of from 0.5 to 30 .mu.m and being present in said curl prevention layer in an amount of 0.02 to 10% by weight.
An image receiving sheet for receiving dye migrated by heat from a heat transfer sheet, comprising a polyvinyl chloride sheet, and a curl prevention layer provided on one surface of said polyvinyl chloride sheet, said curl prevention layer comprising (i) a resin that is non-heat shrinkable and stretchable, and has a heating shrinkage or stretchability measured by JIS-K-6734 within a range of from -1.0 to 1.5%, and (ii) a filler which makes the curl prevention layer slippery, said filler having a particle size of from 0.5 to 30 .mu.m and being present in said curl prevention layer in an amount of 0.02 to 10% by weight.
A method of preventing curling of an image receiving sheet for receiving dye migrated by heat from a heat transfer sheet, said method comprising:
