Photochromic polymerizable composition

摘要

A photochromic polymerizable composition comprising (a) a polyfunctional (meth)acrylate monomer, (b) at least one kind of chromene compound selected from the group consisting of three kinds of chromene compounds represented by particular structural formulas, and (c) a compound having at least one or more epoxy groups in the molecules. The photochromic polymerizable composition offers a photochromic material that exhibits little initial color and excellent photochromism resistance suited for use as lenses for spectacles.
