Abstract:
A liquid curable resin composition comprising,(1) 10-90 wt. %, relative to the total composition, of a poly(meth)acrylate polymer comprising epoxy groups and having a weight average molecular weight of about 5,000-400,000,(2) a ring-opening polymerizable monomer selected from bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, hydrogenated bisphenol A diglycidyl ether, 3,4-epoxycyclohexyl methyl-3,4-epoxycyclohexane carboxylate, bis(3,4-epoxycyclohexyl methyl)adipate, 1,4-butanediol diglycidyl ether, 1,6-hexanediol diglycidyl ether, glycerol triglycidyl ether, trimethylolpropane triglycidyl ether, polyethylene glycol diglycidyl ether and/or polypropylene glycol diglycidyl ether, and(3) a cationic photopolymerization initiator,(4) a radically polymerizable monomer comprising at least one ethylenically unsaturated group, and(5) a free radical photo-initiator.
