PURPOSE:To prepare a resin compsn. which quickly cures by ultraviolet radiation, gives a highly wear-resistant cured product, and gathers little dust, by compounding a specific (meth)acrylate compd., an alkali or alkaline earth metal salt, and an ethylenically unsatd. compd. as essential components. CONSTITUTION:The title resin compsn. suitably used as an optical disc material, a coating compsn., etc., is prepd. by compounding: a (meth)acrylate compd. contg., as its segment, at least one compd. selected from the group consisting of polyethylene glycol, polypropylene glycol, and their derivs. (e.g. urethane acrylate); at least one compd. selected from the group consisting of an alkali or alkaline earth metal salt and a protonic acid (e.g. lithium perchlorate); an ethylenically unsatd. compd. other than the (meth)acrylate compd. (e.g. trimethylolpropane triacrylate); and, as an optional component, a photopolymn. initiator (e.g. benzoin). |
