Abstract
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):[a1]-[b]-[a2] (1)wherein [a1] and [a2] 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 [a1] and [a2]/(mass of [b])=5/95 to 80/20.
