EASY-TO-ADHERE POLYAMIDE FILM

摘要

PROBLEM TO BE SOLVED: To provide an easy-to-adhere polyamide film excellent in dimensional stability and also excellent in adhesiveness under a wet condition without damaging bending fatigue resistance and transparency. SOLUTION: An adhesion modified layer comprising a resin compsn. based on a self-crosslinkable polyester graft copolymer wherein at least one polymerizable unsaturated monomer containing an acid anhydride having a double bond is grafted to a hydrophobic polyester resin is laminated to at least the single surface of a substrate film wherein an X-layer based on at least one aliphatic polyamide resin selected from the group consisting of nylon 6 and nylon 66 and a Y-layer based on at least one aliphatic polyamide resin selected from the group consisting of nylon 12, nylon 612 and nylon 6/12 form layered constitution of X/Y or Y/X/Y.
