AQUEOUS POLYURETHANE RESIN COMPOSITION, AND HIGHLY-ADHESIVE POLYESTER FILM TO WHICH SAID AQUEOUS POLYURETHANE RESIN COMPOSITION HAS BEEN APPLIED

摘要

Provided are: an aqueous polyurethane resin composition having excellent adhesiveness to synthetic resins, and tackiness and blocking resistance after application, said composition having (A) a polyol, (B) a polyisocyanate, (C) a hydrophilic compound represented by general formula (1), (D) a monohydroxy vinyl ether compound represented by general formula (2), and water as essential components; and a highly-adhesive polyester film having a highly-adhesive layer obtained by applying the aqueous polyurethane resin composition to at least one surface of the polyester film. The aqueous polyurethane resin composition is characterized in that the amount of an alkylene oxide unit represented by (C2H4-O)n in the (C) component is 3 to 20 mass% of the solid content comprising the (A) to (D) components, and the content of the (D) component is 3 to 25 mass% of the aforementioned solid content.
