PURPOSE:To impart excellent releasability and to prevent the lowering of gloss by forming a receiving layer using a polyester resin and an isocyanate compound as main components and forming at least the substrate under the receiving layer of a PET film. CONSTITUTION:A dye receiving layer based on a polyester resin and an isocyanate compound is provided on a substrate containing a PET film. As the isocyanate compound, tolylene dissocyanate and hexamethylene diisocyanate are used and an adduct of the isocyanate compound and hexane tolyol can be also used. The use ratio of the polyester resin and the isocyanate compound is pref. within a range of 0.2-2.0 in a NCO/OH mol. ratio, for example, when the polyester resin contains OH. As the PET film, a white PET film is desirably used. The thickness of the substrate is pref. 50-200mum and the coating amount of the dye receiving layer to the substrate is pref. 0.1-20g/m<2> on a solid amount basis. |
