Claims
- 1. An optical lens comprising a high surface hardness transparent resin which comprises a crosslinked polymer prepared by copolymerizing a monomer (A) represented by the formula (I): ##STR457## wherein when n is an integer of 1 to 3, and X is oxygen or sulfur, and when n is 1 and X is oxygen, R is selected from the group consisting of --CH.sub.3, --C.sub.2 H.sub.5, --C.sub.3 H.sub.7, --C.sub.4 H.sub.9, --C.sub.5 H.sub.11, --C.sub.6 H.sub.13, --C.sub.2 CCl.sub.3, ##STR458## when n is 2 and X is oxygen, R is selected from the group consisting of ##STR459## when n is 2 and X is sulfur, R is selected from the group consisting of --(CH.sub.2).sub.i --wherein i=2-6, ##STR460## when n is 3 and X is oxygen, R is selected from the group consisting of ##STR461## and the substituent on the aromatic ring is present at the m-position or the p-position thereof, and a monomer (B) having, in one molecule, m functional groups of it least one kind selected from the group consisting of CH.sub.2 .dbd.CH--C(O)--O--, CH.sub.2 .dbd.C(CH.sub.3)--C(O)--O-- and ##STR462## and wherein (n+m) is an integer of 3 or more.
- 2. The optical lens of claim 1 wherein X is oxygen.
- 3. The optical lens of claim 1 wherein the monomer (A) is selected from the group of monomers represented by formulae (V) and (VI): ##STR463## wherein when n is 2, and R is selected from the group consisting of --(CH.sub.2).sub.i -- wherein i=2-6, ##STR464## wherein i=1 or 2, ##STR465## wherein i=0 or 2, --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 CH.sub.2 -- ##STR466## and the substituent on the aromatic ring is present at the m-position or the p-position thereof ##STR467## wherein when n is 3 and R is selected from the group consisting of ##STR468##
