Abstract
Abstract Disclosed is a resin composition comprising 20 to 90 parts by weight of an ethylene/(meth)acrylic ester/carbon monoxide terpolymer having been graft modified with an unsaturated carboxylic acid or its anhydride and 80 to 10 parts by weight of a polyester elastomer having been graft modified with the above modifier, the total amount of said graft modified ethylene/(meth)acrylate/carbon monoxide terpolymer and polyester elastomer being 100 parts by weight. Also disclosed is an adhesive comprising the above-mentioned resin composition. The resin composition and the adhesive according to the invention are excellent in adhesion properties, heat resistant adhesive properties, hue and heat stability.
