<P>PROBLEM TO BE SOLVED: To provide a polymerizable compound that can be a raw material for producing a resin having high transparency, excellent heat resistance and mechanical strength, required of an optical component such as a plastic lens, and having a high refractive index exceeding a refractive index (nd) of 1.7, and an optical component made from the resin. <P>SOLUTION: The compound includes at least two thiol groups and one species selected from metal atoms in its molecule. There are disclosed a polythiol composition comprising the compound, a polymerizable composition comprising the polythiol composition, and a resin produced by polymerizing the polymerizable composition. The optical component is made from the resin. <P>COPYRIGHT: (C)2011,JPO&INPIT |
