Abstract:
1. A cationic polymerizable resin composition comprising (A) a compound having at least one functional group capable of cationic ring-opening polymerization and (B) a cationic polymerization initiator to generate active species by electromagnetic wave or particle beam, which further comprises (C) a compound to generate a carbocation by the action of the active species generated from (B) the cationic polymerization initiator by electromagnetic wave or particle beam, in an amount of 0.01 to 10.0 % by weight based on 100 % by weight of the sum of the components (A) and (C), wherein the composition does not contain an epoxy compound, and wherein the component (B) is contained in an amount of 0.5 to 10.0 parts by weight based on 100 parts by weight of the sum of the components (A) and (C), and the component (B) is represented by the following formula (1): wherein the cation is an onium ion; W is I; R1, R2, R3, and R4 are the same or different organic groups; a, b, c and d are an integer from 0 to 3, respectively, and (a+b+c+d) is equal to a valence number of W; M is B, P, As, Sb, Fe, Sn, Bi, Al, Ca, In, Ti, Zn, Sc, V, Cr, Mn or Co; X is a halogen atom selected from F, Cl and Br, or C
