Abstract:
A composite printing film comprising:a substrate film comprising a synthetic polymeric material; an adhesive undercoat layer formed on the substrate film and comprising an adhesive resin comprising at least one member selected from the group consisting of ethylene-(meth) acrylate ester-(meth) acrylic acid copolymers, ethylene-(meth) acrylate ester-(meth) acrylate salt copolymers, ethylene -(meth) acrylate ester-maleic anhydride copolymers and ethylene-glycidyl(meth) acrylate copolymers: an anchor layer formed on the adhesive undercoat layer and comprising at least one member selected from the group consisting of oxazoline group-containing polymer resins and ethylimine group-containing polymer resin; and a top layer formed on a surface of the anchor layer and comprising a binder resin comprising a mixture of (a) at least one polymer having ester bonds of the formula: â€”COâ€”Oâ€”, and exhibiting a glass-transition temperature of âˆ’20 to 20Â° C. with (b) at least one ester bond-containing polymer having a glass transition temperature of 40 to 80Â° C., said top layer having a printing surface having an arithmetical mean roughness Ra of 0.2 to 3.5 &mgr;m, determined in accordance with Japanese Industrial Standard B 0601-1994.
