    摘要： This invention provides sulfur-containing (meth)acrylic ester compounds each of which is represented by the following formula (1);
    wherein R 1 and R 2 each independently represent a hydrogen atom or an alkyl group or may be fused together to form a ring, R 3 represents a hydrogen atom or a methyl group, X 1 represents an oxygen atom or a sulfur atom, m stands for an integer of from 0 to 3, and n stands for an integer of from 1 to 4, polymerizable compositions comprising the sulfur-containing (meth)acrylic acids, and cured products and optical parts obtained by polymerizing the polymerizable compositions. The sulfur-containing (meth)acrylic ester compounds according to the present invention are very useful, as monomers for photocurable, polymerizable compositions, in applications such as optical materials and dental materials. The optical parts obtained by curing the polymerizable compositions are excellent in optical properties, thermal properties and mechanical properties and are also good in productivity.
