ABSTRACT:
An electrothermal transfer sheet whose resistor layer is free from heat shrinkage and is excellent in flexibility and adhesion to a substrate sheet can be produced with high productivity. The transfer sheet includes a substrate sheet, a heat-transferable dye layer formed on one surface of the substrate sheet, and a resistor layer capable of generating heat when an electric current is applied thereto from an electrode head, formed on the other surface of the substrate sheet. The resistor layer includes (a) a binder resin, (b) an electrically conductive filler and (c) a crosslinking agent which includes a mixture of a thermosetting crosslinking agent and an ionizing-radiation-curable crosslinking agent.
