PURPOSE:To obtain an ink compsn. for thermal transfer recording having high sublimation speed and good image stability after transfer by compounding a dye having a specific structure for thermal transfer recording, a binder resin and an org. solvent and/or water. CONSTITUTION:An ink compsn. for thermal transfer recording is prepared by compounding a dye for thermal transfer recording represented by formula (wherein R1 and R2 are an alkyl group or a halogenoalkyl group, R2 and R3 are H, a l = 4C alkyl group or an alkoxy group, R4 and R5 are a 1-4C alkyl group or an alkoxy group and R6 and R7 are an alkyl group or an alkenyl group), a binder resin and an org. solvent and/or water. The aforementioned ink compsn. is applied to the dye supporting layer formed on one surface of a base material sheet and dried to support the dye for thermal transfer recording to form a transfer sheet. As a concrete example of the binder resin, there is a rosin or phenol type binder resin and, as a concrete examaple of the solvent, there is alcohol such as methanol or ethanol. |
