Abstract:
1. A laminate obtained by subjecting a prepreg to laminate molding, wherein the prepreg is obtained by applying a resin composition, for use in production of the laminate, to a substrate so that the substrate is impregnated with the resin composition, and then drying them, wherein the resin composition comprises: (a) a biphenyl novolak epoxy resin represented by the following general formula (1): wherein each of R (b) a dihydroanthracene epoxy resin represented by the following general formula (3): wherein R 9 each occurrence independently represents a C t H 2t+1 group, wherein t represents 0 or an integer of 1 or more, r represents an integer of 0 to 4, R 10 each occurrence independently represents a C u H 2u+1 group, wherein u represents 0 or an integer of 1 or more, and s represents an integer of 0 to 6, and (c) a curing agent, and the resin composition has a molecular weight between crosslinking sites of 300 to 1,000 after curing of the resin composition, as determined from an elastic shear modulus measured at a temperature of Tg or higher.
