Abstract:
A resin composition excellent in tintability and resin strength, a resin obtained by curing such a resin composition, and an optical component is provided. A polymerizable composition containing an isocyanate compound suitably used for transparent resin materials, at least one polythiol compound which may have one or more (poly)sulfide bonds in a molecule, and at least one polyhydroxy compound having two or more hydroxy groups in a molecule and/or at least one (poly)hydroxy(poly)mercapto compound having one or more hydroxy groups and one or more thiol groups is used.
