ABSTRACT:
An adhesive resin composition is described, comprising: (A) a thermoplastic copolyester resin prepared from (1) a dicarboxylic acid component comprising from 40 to 100 mol % of terephthalic acid and from 0 to 60 mol % of other aromatic dicarboxylic acid and (2) a low molecular weight glycol component comprising from 40 to 100 mol % of 1,4-butanediol and from 0 to 60 mol % of diethylene glycol or 1,6-hexanediol and further from 0 to 10 mol %, based on the total carboxylic acid, of polytetramethylene glycol having a molecular weight of from 600 to 6,000, which has a melting point of from 90.degree. to 160.degree. C. and a reduced viscosity of at least 0.5; and (B) an ethylene copolymer having at least one functional group selected from an epoxy group, a carboxylic acid group, and a dicarboxylic anhydride gruop; and if desired, (C) a thermoplastic resin other than the resin (A), and if further desired, (D) a polyfunctional epoxy compound. This composition exhibits excellent adhesion to synthetic resins such as polyvinyl chloride, polyesters, and polyolefins and also to metals such as aluminum and has excellent adhesive durability against moisture.
