发明名称 Polythiourethane-based polymerizable composition and optical resin obtained from the same
摘要 Provided are a polymerizable composition for giving a resin which has a high refractive index and low dispersion, and is especially excellent in impact resistance and tintability; and a resin and an optical component each obtained by curing the composition. There used a polymerizable composition comprising (A) a compound represented by Formula (1) and/or by Formula (2), at least one compound as the following component (B), and at least one compound as the following component (C): (B) polythiol compounds optionally having at least one (poly)sulfide bond in a molecule, and (C) compounds represented by Formula (3): <?in-line-formulae description="In-line Formulae" end="lead"?>HO-[R1-(Y)n]m-R2-X (3)<?in-line-formulae description="In-line Formulae" end="tail"?> (in above Formula (3), X is an OH group or a SH group; Y is an oxygen atom or a sulfur atom; R1 and R2 are each independently an optionally substituted methylene group or an optionally substituted alkylene group having carbon atoms of not smaller than 2 and not larger than 4; n is an integer of 0 or 1 when Y is an oxygen atom, or 0 or an integer of not smaller than 1 and not larger than 2 when Y is a sulfur atom; and m is 0 or an integer of not smaller than 1 and not larger than 3, provided that (carbon number of R1+n)xm+(carbon number of R2) is 3 or larger).
