PURPOSE:To enhance releasability by forming a receiving layer using a vinyl chloride resin containing active hydrogen, a polyester resin and an isocyanate compound as main components. CONSTITUTION:A receiving layer is based on a vinyl chloride resin containing active hydrogen, a polyester resin and an isocyanate compound. As the vinyl chloride resin containing active hydrogen, for example, a polyvinyl alcohol modified vinyl chloride/vinyl acetate copolymer is designated. As the isocyanate compound, tolylene dissocyanate and hexamethylene diisocyanate are used. The use ratio of the vinyl chloride resin containing active hydrogen and the isocyanate compound is pref. within a range of 0.2-2.0 in a NCO/OH mol ratio. The formulation ratio of the vinyl chloride resin and the polyester resin is pref. set so that 50-100 pts.wt. of the polyester resin is used per 100 pts.wt. of the vinyl chloride resin. |
