Production method for photochromic optical material |
| abstract |
A process for producing a photochromic optical material according to the present invention is a process for producing a photochromic optical material, which comprises mixing at least one polymerizable monomer (A) having at least two ethylenically unsaturated groups and at least one polythiol (B) (Ii) a step of mixing the prepolymer and the photochromic compound (C) to obtain a polymerizable composition, (iii) a step of polymerizing the polymerizable composition (iii) Wherein in the step (i), the number of moles of the mercapto group of the polythiol (B) is less than the number of moles of the ethylenic unsaturated group of the polymerizable monomer (A). |
