摘要： The present invention provides a resin composition for an adhesive, being useful as a component of an adhesive having a favorable adhesion property to glass and giving favorable appearance after adhesion. The resin composition for an adhesive contains a polyhydroxyurethane resin. This polyhydroxyurethane resin contains a structural unit formed by polymerizing a compound (A) having at least two five-membered cyclic carbonate structures and a compound (B) having at least two primary amino groups, the polyurethane resin contains a urethane bond, a hydroxy group, and a secondary amino group in the structural unit. Further, this polyhydroxyurethane resin has an amine number of 1 to 50 mgKOH/g and has a hydroxyl number of 10 to 230 mgKOH/g.
