ABSTRACT:
An electro-sensitive thermal transfer recording medium comprises a metal support, and an electric resistor layer which is formed on one side of the metal support and comprises a resin and a conductive powder, said resistor layer having an absolute value of a linear expansion coefficient of not larger than 2.times.10.sup.-5 /.degree.C. in a temperature range of from 23.degree. C. to 450.degree. C., a tensile elongation of not larger than 5% at a stress of 0.5 Kgf/mm, and a volume specific resistance of from 10.sup.-1 to 10.sup.3 .OMEGA.cm at 23.degree. C. The medium may have an ink layer on the resistor layer or on the opposite side of the metal support. Alternatively, a powder ink-retaining layer may be formed on the other side of the metal support. In the latter type of medium, a powder ink is applied to the ink-retaining layer for electro-sensitive thermal transfer recording.
