<p>A resin composition comprising (A) 30 to 80% by weight of an amino group-containing unsaturated ester compound obtained by subjecting (c) a compound represented by the formula III: <CHEM> wherein R<3> and R<4> are independently hydrogen atom or methyl group, and possessing an epoxy group and a radically polymerizable unsaturated bond to a ring-opening addition reaction with at least one aromatic amine selected from the group consisting of (a) an aromatic polyamine represented by the formula I: <CHEM> wherein R<1> is an atom or an organic group selected from the class consisting of hydrogen atom, halogen atom, methoxy group, and alkyl groups of 1 to 5 carbon atoms and m is an average in the range of 0 to 10, and (b) an aromatic diamine represented by the formula II: <CHEM> wherein R<2> is an atom or an organic group selected from the class consisting of hydrogen atom, halogen atom, methoxy group, and alkyl groups of 1 to 5 carbon atoms and n is an average in the range of 0 to 10, providing that when n is 0, X is a divalent organic group selected from the class consisting of <CHEM> or, when n is an average of more than zero, X and A are independently a divalent organic group selected from the class consisting of <CHEM> in a ratio in the range of 0.25 to 0.9 equivalent weight of (c) said compound to 1 equivalent weight of the hydrogen atom directly connected to the nitrogen atom contained in said aromatic amine, (B) 10 to 60% by weight of an epoxy compound possessing at least two epoxy groups in the molecular unit thereof, and (C) 5 to 60% by weight of a radically polymerizable cross-linking agent (providing that the total of said compounds of (A), (B), and (C) is 100% by weight).</p> |
