Abstract
A sulfur-containing O-(meth)acrylate compound of the following formula (1) is useful as a starting material for a resin composition used in optical applications such as a lens; ##STR1## PA1 wherein R represents hydrogen atom or methyl group; 1 represents an integer from 1 to 3; B is ##STR2## PA1 when B is ##STR3## PA1 n is 2; m is 1 or 2; A is selected from the following groups: ##STR4## PA1 wherein m represents 1 or 2; each ring may be substituted by one or more alkyl, alkylthio or alkoxy groups having 1 or 2 carbon atoms; p and q are 0 or 1, PA1 while m is 1 when p is 1; PA1 when B is ##STR5## PA1 n is 1; m is 2 or 3; A is selected from the following groups: PA1 --(CH.sub.2).sub.r --S--(CH.sub.2).sub.r --, --(CH.sub.2).sub.r --S--S--(CH.sub.2).sub.r --, --(CH.sub.2).sub.r --S--(CH.sub.2).sub.s --S--(CH.sub.2).sub.r -- and ##STR6## PA1 wherein r and s are an integer from 1 to 3; PA1 when B is ##STR7## PA1 n is 1; m is 2; A is selected from the following groups: PA1 --(CH.sub.2).sub.r --S--(CH.sub.2).sub.r --, --(CH.sub.2).sub.r --S--S--(CH.sub.2).sub.r -- and PA1 --(CH.sub.2).sub.r --S--(CH.sub.2).sub.s --S--(CH.sub.2).sub.r -- PA1 wherein r and s are an integer from 1 to 3.
