PHOTOCHROMIC POLYMERIZABLE COMPOSITION |
| 摘要 |
A photochromic polymerizable composition comprising (a) a polyfunctional (meth)acrylate monomer, (b) at least one member selected from the group consisting of three kinds of chromene compounds represented by specific structural formulae, and (c) a compound having at least one epoxy group in the molecule. The composition gives a photochromic material which is reduced in initial color, excellent in long-lasting photochromism, and suitable for use as, e.g., a spectacle lens.
