PURPOSE:To obtain a transfer image generating no lowering of close adhesiveness under a high temp. and high humidity condition and excellent in gradation properties by forming an easy adhesion layer by applying a coating solution consisting of an aqueous copolymer obtained by copolymerizing a specific compound and an aqueous isocyanate compound to a film and stretching the coated film after drying. CONSTITUTION:An easy adhesion layer and a sublimation type ink layer are provided to the single surface of a biaxially stretched polyester film in this order and the easy adhesion layer is formed by applying a coating solution consisting of an aqueous copolymer obtained by copolymerizing a compound having a phosphate group or a phosphoric ester group represented by formula (1) (wherein R1 is a hydrogen atom, a 1 - 20C alkyl group, a monoethanolamine group, a dimethylaminoethyl methacrylate group or a diethylaminoethyl methacrylate group) and other compound having an ethylenic unsaturated bond and an aqueous isocyanate compound to a film and stretching the coated film after drying. As the other compound having the ethylenic unsaturated bond copolymerized with the compound having the unsaturated bond, alkyl acrylate can be designated. |
