Abstract:
1. A resin composition, comprising: (A) at least one polyisobutylene resin; (B) at least one polyisoprene resin and/or at least one polyisobutylene resin, each having a functional group capable of reacting with an epoxy group; (C) at least one tackifier resin; and (D) at least one epoxy resin, wherein: the ratio of equivalents of epoxy groups in said at least one epoxy resin (D) to equivalents of functional groups in said at least one polyisoprene resin and/or at least one polyisobutylene resin (B) is 1:0.4 to 1:2; the mass ratio of said at least one epoxy resin (D) to said at least one polyisoprene resin and/or at least one polyisobutylene resin is 1:2 to 1:6; and the total amount of said at least one polyisoprene resin and/or at least one polyisobutylene resin (B) and said at least one epoxy resin (D) present in said resin composition is 0.1 mass % to 50 mass %, relative to 100 mass % of non-volatile components of said resin composition.
