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.
一种热塑性复合膜,包含热塑性基材薄膜和由包含聚酯接枝共聚物(A)和树脂(B)的树脂组合物形成的层,该层至少形成在热塑性基材薄膜的一侧、聚酯接枝共聚物(A)是通过将至少一种可聚合的不饱和单体接枝到疏水性聚酯树脂上获得的,该单体含有具有双键的酸酐,树脂(B)含有至少一种选自聚氨酯树脂、丙烯酸树脂和乙烯基树脂的成员。本发明热塑性复合膜的粘合改进层在广泛的应用中显示出卓越的粘合强度。具体来说,在印刷油墨、UV 油墨等的油墨层;干式层压和挤压层压中的粘合层;通过真空蒸镀、电子束蒸镀、溅射离子镀、CVD 和等离子聚合金属或无机物或其氧化物而获得的薄膜层;氧气吸湿层;有机阻隔层;喷墨图像接收层等方面都有明显的效果。
