SELENIZED TRANSPARENT OPTICAL MATERIAL

摘要

A transparent optical material containing at least one selenium atom; a plastic lens made of the optical material; processes for producing these; and novel selenium compounds useful for producing the transparent optical material and plastic lens and represented by general formula (1), formula (2): (Z<2>) q - (SH) r, or formula (4): (Z<3>) - (X<2>) s, wherein Y<1> and Z<1> each represents C, S, etc.; X<1> represents a polymerizable functional group such as SH, NCO, or acryloyl; Z2 represents alkylene containing at least one Se atom; q is an integer of 1 to 20; r is an integer of 3 to 6; Z<3> represents Se or alkylene containing at least one Se atom; X<2> represents a functional group such as (meth)acrylol; and s is an integer of 2 to 6.
