Soft cross-linked polyester resin film exhibiting self adhesive, remolding, and scratch repairing and its manufacturing method

摘要

SubjectIt is to provide a crosslinked polyester resin excellent in transparency, adhesion, flexibility (elongation), strength (Young's modulus), and remolding and scratch repairing and a multilayer crosslinked polyester resin film formed by the film shape.SolutionA polyester resin 5 containing a multipoint covalent cross-linking portion 3 comprising a polypeptide main chain 1 containing a plurality of ester bonds 2, a multivalent covalent cross-linking portion 3 comprising an ester bond 2 and a free OH group 4, and a polyester resin material containing a ester bond 2 and a carboxylic acid group, and a diepoxy crosslinking agent The transesterification catalyst 6 is mixed, heated, and crosslinked.
