Abstract:
A radiation curable resin composition, comprising:(i) a liquid constituent comprising:(A) 30-95 wt %, based on total weight of said liquid constituent, of a cationic polymerizable organic component composed of 50 wt. or more of an epoxy compound selected from the group consisting of 3,4-epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate and bis(3,4-epoxycyclohexylmethyl) adipate;(B) 0.110 wt %, based on total weight of said liquid constituent, of a cationic photopolymerization initiator that is an onium salt;(C) 5-30 wt %, based on total weight of said liquid constituent, of a ethylenically unsaturated monomer component composed of 60 wt % or more of a polyfunctional monomer having three or more ethylenically unsaturated groups; and(D) 0.01-10 wt %, based on total weight of said liquid constituent, of a radical photopolymerization initiator; and(ii) 50-80 wt %, based on total weight of the composition, of an inorganic or organic filler.
