Resin composition, polyurethane adhesive agent, and layered product

Abstract

There is provided a resin composition useful as a base resin of a polyurethane-based adhesive that makes it possible to form an adhesive layer excellent in adhesion and heat resistance, that is unlikely to cause a fault, such as floating and peeling, even when being subjected to shaping such as drawing and makes it possible to produce a laminate having a satisfactory appearance, and that is excellent in wettability to a substrate of a resin, a metal, or the like. The resin composition is a resin composition to be used as a base resin of an adhesive together with a curing agent, the resin composition being a resin composition for a polyurethane-based adhesive. The resin composition contains a polyol (A) containing 80% by mass or more of a polyurethane resin (c) having a constituent unit derived from a polyol containing a polyester polyol (a), wherein the polyester polyol (a) has a constituent unit derived from a dicarboxylic acid component containing benzene-o-dicarboxylic acid, the content of a terminal hydroxy group of the polyester polyol (a) is 0.1 to 2 mol/kg, and the content of a terminal hydroxy group of the polyurethane resin (c) is 0.04 to 0.4 mol/kg.
