Abstract
Abstract A curable resin composition comprising (A) 100 parts by weight of an organic rubbery polymer having a cross-linkable group of the formula: wherein R¹ and R² are the same or different and each a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms, (B) 70 to 500 parts by weight of an epoxy resin, (C) 0.1 to 20 parts by weight of a silanol condensation catalyst per 100 parts by weight of the organic rubbery polymer (A), (D) 0.1 to 300 parts by weight of a curing agent for the epoxy resin per 100 parts by weight of the epoxy resin (B), and (E) a silicon-containing compound having a cross-linkable group of the formula: wherein R¹ and R² are the same as defined and a functional group reactive with an epoxy group, wherein a weight ratio of the total weight of the organic rubbery polymer (A) and the epoxy resin (B) to the weight of the silicon-containing compound (E) is from 100:0.1 to 100:20, which provides a cured product with high modulus.
