Abstract:
A photopolymerizable composition comprising, based upon the weight of said composition, about 5 to 45 percent of an epoxy resin, about 94 to 55 percent of a material copolymerizable with said enoxy resin, and about 1 to 10 percent of a free radical photoinitiator, said copolymerizable material including an effective amount of at least one free radically polymerizable compound selected from the comonomer group consisting of (1) an acrylamide and (2) a vinyl or (meth)acrylic monomer containing amide functionality or an hydroxyl group, said epoxy resin and copolymerizable material being reactive with one another in a single step initiated by said free radical photo initiator and having little or no tendency for premature reaction.
