CURABLE RESIN COMPOSITION, ADHESIVE COMPOSITION, CURED OBJECT OR COMPOSITE

摘要

A curable resin composition that is adhesive and transparent. The curable resin composition comprises (1) a polymerizable vinyl monomer, (2) a curing agent, (3) a reducing agent, and (4) an acrylic block copolymer having a structure represented by formula (1): [a 1 ]-[b]-[a 2 ] (1) wherein [a 1 ] and [a 2 ] each independently represents a polymer block which consists mainly of structural units derived from an alkyl acrylate and/or an alkyl methacrylate and has a glass transition temperature of 90 °C or higher, and [b] represents a polymer block which consists mainly of structural units derived from an alkyl acrylate and/or an alkyl methacrylate and has a glass transition temperature of -10 °C or lower, the copolymer satisfying the relationship (total mass of [a 1 ] and [a 2 ]/(mass of [b]) = 5/95 to 80/20.
