Japanese Patent JP2979022

B2

The present invention relates to a transparent resin which has a high surface hardness and which is excellent in scratch resistance, heat resistance and chemical resistance, a glazing material, a protective cover for display devices, an optical lens and a hard coat material comprising the above-mentioned resin, and a novel polymerizable monomer represented by the formula (I) useful as a raw material for the high surface hardness transparent resin. wherein R is an aliphatic residue having or not having an oxygen atom, an alicyclic ring, a heterocyclic ring or an aromatic ring, or an alicyclic residue, l is 0 or 1, each of i and j is an integer of 1 or more, and when l =0, i=j=1, when l =1, (i+j) is 4 or less, when j=1, X is oxygen or sulfur, when j>/=2, all X's are oxygen or sulfur, or one X is oxygen and the other X's are sulfur, or one X is sulfur and the other X's are oxygen. The high surface hardness transparent resin comprises a crosslinked polymer prepared by copolymerizing a monomer (A) represented by the formula (I) as above and a monomer (B) containing one or more functional groups of at least one kind selected from the group consisting of CH2=CH-C(O)-O-, CH2=C(CH3)-C(O)-O- and s
