PURPOSE:To provide desirable spectral characteristics, easy sublimation, high strength against light and heat, various chemicals, scarce decrease in sharpness and hard retransfer of an image by providing specific colorant in a colorant layer. CONSTITUTION:A heat sensitive transfer material having a colorant containing colorant represented by formula I or/and II is made. In the formula, R1-R6 are hydrogen atom, alkyl group, alkoxy group, halogen atom, acylamino group, alkoxycarbonyl group, cyano group, sulfonylamino group, carbamoyl group or sulfamoyl group, R7-R10, R13-R15 are hydrogen, alkyl group, alkoxy group, halogen atom, acylalkyl group, alkoxycarbonyl group, cyano group, alkoxycarbonylamino group, aminocarbonylamino group, sulfonylamino group, carbamoyl group, or sulfamoyl group, R11, R12 are alkyl group, and R16 are alkyl group, aryl group or heterocyclic group. |
