Abstract
A thermal transfer recording film is disclosed, comprising a support having thereon an image protective layer containing a binder composed of a resin soluble in an organic solvent incapable of dissolving the support, said resin having a glass transition point or a melting point of not lower than 60.degree. C., and an adhesive layer containing a binder composed mainly of a polyester resin comprising terephthalic acid as a main acid component, said polyester resin having a glass transition point of from 30.degree. C. to 60.degree. C., in this order, at least one of said image protective layer and adhesive layer containing a coloring material. The recording film forms a transferred image having durability and satisfactory image quality on a smooth surface of a material such as glass, as well as paper and resin films, with a low heat energy.
