A method of producing a thermal transfer image recording sheet is provided including the steps (a) bonding a surface of a substrate sheet to a plastic film through a layer of a polymeric binder having a glass transition temperature of 50.degree. C. or less to form a first laminate; (b) heat setting the first laminate under pressure at a temperature higher than the glass transition temperature of the polymeric binder layer to remove stress from the finished thermal transfer image recording sheet; and (c) forming a thermal transfer image-receiving layer on an exposed surface of the plastic film to produce the thermal transfer image recording sheet.
