PHOTOCHROMIC CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2009/075388
Kind Code:
A1
Abstract:
Disclosed is a photochromic curable composition which enables formation of a photochromic cured body that exhibits good photochromic characteristics for a long time, while having excellent mechanical strength. By using the photochromic curable composition, a photochromic cured body can be produced at low cost. Specifically disclosed is a photochromic curable composition containing 0.001-10 parts by mass of [E] a photochromic compound per 100 parts by mass of polymerizable monomers composed of [A] not less than 0.1 part by mass but less than 5 parts by mass of a radically polymerizable monomer having a specific epoxy group, [B] not less than 1.0 part by mass but not more than 15 parts by mass of a specific polyfunctional radically polymerizable monomer, [C] not less than 1.0 part by mass but not more than 30.0 parts by mass of a specific di(meth)acrylate monomer, and [D] more than 50.0 parts by mass but not more than 97.9 parts by mass of a (meth)acrylate and/or a thio(meth)acrylate other than the components [A]-[C].
