PURPOSE:To clearly form an image and to easily form a recording image having excellent various rigidity by providing a layer for supporting dye represented by a specific general formula on one side face of a base material sheet to form a heat transfer sheet. CONSTITUTION:Dye represented by a formula I (A is cyano group, alkoxycarbonyl group, etc. R1 is alkyl group, aralkyl group, aryl group, etc., R2 is alkyl group, aralkyl group, etc., R3 is H, alkyl group, etc., R4 is H, alkoxy group, etc., Z is H, etc., and n, m are numbers of 1, 2.) is mixed with binder resin, etc., in a suitable solvent, and dissolved or dispersed to prepare a supporting layer forming coating solution. A base material sheet such as paper, synthetic paper, plastic film, etc., is coated with the solution 0.5-50mum thick, and dried to form a dye supporting layer, thereby obtaining a heat sensitive transfer sheet. |
