Abstract
This invention relates to (meth)acrylates represented by formula (1): ##STR1## wherein, R.sub.1 and R.sub.2 are each independently H or CH.sub.3 and average value of n is 1-5; resin composite comprising (A) an urethane (meth)-acrylate and/or epoxy (meth)acrylate, (B) a (meth)-acrylate represented by formula (1) above, (C) an ethylenically unsaturated compound other than component (A) or (B), and (D) a photopolymerization initiator; and cured products of said resin composites. The cured products of said resin composites of this invention have high refractive index and are superior in mold release property, shape reproducibility, restorability, and scratch resistance and suited in particular for transmission type screens.
