PURPOSE:To prevent decrease of sensitivity, and density decrease and fading of a recorded image from occurring by adding a polymer having a specific repetitive unit as a main component within a specific range rate in a sublimate dye accepting layer. CONSTITUTION:A sublimate dye accepting layer contains 5wt.% or over up to and including 95wt.% of a polymer A having a repetitive unit as given in the formula I as a main component in a sublimate transfer recording image receiving having the sublimate dye accepting layer at least on its side surface. In the formula I, R indicates hydrogen, or methyl radical, M indicating hydrogen, alkali metal, alkali earth group or ammonium, and R1, R2, R3 and R4 indicate respectively hydrogen, halogen, alkyl radical or alkoxy radical. As a representative example of a polymer having such a structure, a copolymer with acrylic acid, acrylic ester, methacrylic acid, methacrylic ester or styrene in a form of the formula II, and otherwise a polymer composed of only the formula III can be exemplified. Sensitivity is increased thereby, and density decrease and fading of an image when recording speed is increased are prevented. |
