Adhesive resin composition and adhesive film

摘要

An adhesive resin composition comprising polyester polyurethane having a number average molecular weight of 8,000 - 100,000 and an epoxy resin having two or more epoxy groups per molecule, said polyester polyurethane having an acid value of 100 - 1,000 equivalent/ 10<6> g and the proportion of polyester polyurethane having a molecular weight of not more than 5,000 is not more than 20 wt% and an adhesive film obtained from the adhesive resin composition. The adhesive resin composition and the adhesive film of the present invention have a longer working life and are superior in adhesive property, heat resistance and water resistance.
