PROBLEM TO BE SOLVED: To improve a reprotonating ratio of a transfer pigment in a heat sensitive pigment transfer system. SOLUTION: The heat sensitive pigment transferring assembly is a deprotonated cationic pigment. However, a pigment donor element containing a base material carrying a pigment layer wherein a pigment capable of becoming a cationic pigment having a N-H group forming a part of a conjugated system by being reprotonated is dispersed in a polymer binder, on its surface, is superimposed on a pigment acceptive element containing a base material carrying a pigment image acceptive polymer layer containing a mixture of an organic polymer or an oligomer acid capable of reprotonating the deprotonated cationic pigment and a polymer wherein Tg is under 19 deg.C and acidity is not indicated or is indicated by a negligible amount, on its surface so that the pigment layer comes in contact with the pigment image acceptive polymer layer. |
