<p>PROBLEM TO BE SOLVED: To obtain a radiation hardenable liquid resin capable of being hardened without using a catalyst or an initiator. SOLUTION: This radiation hardenable liquid resin is obtained by polymerizing 20-95wt.% alkylene glycol (meth)acrylate-based monomer of the formula CH2 =C(R<1> )COO(Cn H2n O)m R<2> [R<1> is H or CH3 ; R<2> is a 1-5C alkyl or phenyl; (n) is 1-4; (m) is 3-25], 5-80wt.% vinyl monomer having alicyclic epoxy group in a molecule, and 0-75wt.% polymerizable vinyl monomer other than before monomers, and has 10,000-200,000 number average molecular weight and 1-10,000 poise viscosity (at 50 deg.C).</p> |
