PURPOSE:To eliminate color contamination or ghost development due to the back transfer of sublimable dye of different color from an image receiving layer to an ink layer by laminating at least, two dyeable layers on a substrate, and at the same time, adding a high concentration of specific chemical compound to a lower layer. CONSTITUTION:Two dyeable receptive layers (A), (B) are provided on a substrate. Preferably the layer (A) should consist mainly of dyeable resin and a mold lubricant, while the layer (B) should be composed of dyeable resin as a main constituent. In addition, both layers (A), (B) are allowed to contain one type of chemical compound or more selected from formulae I to V, and further, the layer (B) is allowed to contain a higher concentration of such chemical compounds than is the layer (A), or the layer (B) alone is allowed to contain the compounds. In formula I, R1, R2 are hydrogen, an alkali group and hydroxyl. In formula II, R4, R5, R6, R7 are the same as the mentioned R1, R2; X is -O-, -S-, -CH2-. In formula III, R8, R9 are hydrogen, hydroxyl and its acylether and an alkyl group. In formula IV, R10 to R15 are hydrogen and an alkyl group. In formula V, R16, R17 are hydrogen, hydroxyl and an alkyl group; R18, R19 are hydrogen, an alkyl group and an aralkyl group. |
