Abstract:
A process for producing a photochromic cured body by curing a photochromic composition comprising (A) a polyiso(thio)cyanate compound having at least two isocyanate groups and/or isothiocyanate groups in one molecule, a poly(thi)ol compound having at least two hydroxyl groups and/or thiol groups in one molecule, (C) a mono(thi)ol compound having one hydroxy group or thiol group in one molecule, and a photochromic compound.
