(57) [Summary] (Modified) [Purpose] Donor material for use in thermal transfer processes comprising a support having on one side thereof a thermally transferable fluorescent heterocyclic compound dispersed in a polymeric binder. I will provide a. A donor material for use in a thermal transfer process comprising a support having on one side thereof a thermally transferable fluorescent heterocyclic compound dispersed in a polymer binder, said fluorescent compound being: Corresponds to general formulas (A) and (B): In the formula, R 1 represents a hydrocarbon group or a substituted hydrocarbon group; R 1 2 represents hydrogen, a hydrocarbon group, a substituted hydrocarbon group, a carboxylic acid group, an ester group, a nitro group, a carbamoyl group, a substituted carbamoyl group, an amino group or a substituted amino group; R 3 Is hydrogen, a hydrocarbon group, a substituted hydrocarbon group, a carboxylic acid group, Represents an ester group, a carbamoyl group or a substituted carbamoyl group; R 4 represents hydrogen, a hydrocarbon group or a substituted hydrocarbon group; X represents an electronegative substituent for the carbon atom to which it is attached; Z represents a quinoline nucleus Or represents the atoms necessary to close the ring in such a substituted form. |
