Recording medium for electrothermal transfer printing

Abstract

A recording medium for electrothermal transfer printing comprising a base film, an adhesiveness improving layer provided on one surface of the base film, an electrically resistive layer provided on the adhesiveness improving layer, and a heat-sensitive transfer ink layer provided on the other surface of the base film, said electrically resistive layer comprising a binder comprising a polyvinyl butyral resin as a main component, an electrically conductive powder and an inorganic metallic compound type flame retardant. The content of an electrically conductive powder such as a conductive carbon in the resistive layer can be increased to reduce the electric resistance of the resistive layer and problems such as peeling of the resistive layer can be prevented, and a satisfactory flame resistance can be obtained without increasing the resistivity of the resistive layer. Thus, the electrothermal transfer printing can be conducted satisfactorily without any dangerousness.
