Abstract
A thermoplastic laminate film containing a thermoplastic substrate film and a layer formed from a resin composition containing a polyester graft copolymer (A) and a resin (B), the layer being formed on at least one side of the thermoplastic substrate film, the polyester graft copolymer (A) being obtained by grafting at least one polymerizable unsaturated monomer, which contains an acid anhydride having a double bond, to a hydrophobic polyester resin, and the resin (B) containing at least one member selected from the group consisting of a polyurethane resin, an acrylic resin and a vinyl resin. The adhesion improving layer of the inventive thermoplastic laminate film shows superior adhesion strength in a broad range of applications. Specifically, it is evident in an ink layer of printing ink, UV ink and the like; an adhesive layer in dry laminate and extrusion laminating; a thin film layer obtained by vacuum vapor deposition, electron beam vapor deposition, sputtering, ionic plating, CVD and plasma polymerization of metal or inorganic substance or oxides thereof; an oxygen moisture absorbent layer; an organic barrier layer; an ink jet image receiving layer and the like.
