Abstract:
1. A resin composition for an adhesive, comprising: a polyurethane resin (a-1) containing a carboxyl group, having an acid value of not less than 100 equivalent/10 a polyester resin (a-2) having a number average molecular weight of not less than 5.0×10 an epoxy resin (b) containing a nitrogen atom; and an epoxy resin (c) having a dicyclopentadiene skeleton, wherein a content rate of said polyurethane resin (a-1) to a sum of said polyurethane resin (a-1) and said polyester resin (a-2) is not less than 70 percent by mass and not more than 95 percent by mass, a content rate of the total epoxy resin contained in the resin composition to the sum of said polyurethane resin (a-1) and said polyester resin (a-2) is not less than 5 percent by mass and not more than 30 percent by mass, and a blending ratio of said epoxy resin (b) is not less than 0.1 percent by mass and not more than 20 percent by mass of the total epoxy resin contained in the resin composition.
