Document Type and Number:
WIPO Patent Application WO/2013/058218
Kind Code:
A1
Abstract:
A photochromic curable composition according to the present invention is characterized by comprising: a (meth)acrylate compound represented by formula (1-X1) (wherein Y represents an oxygen atom or a bivalent group represented by -NH-; R1 and R2 independently represent a hydrogen atom or a methyl group; R3 represents an alkylene group having 1-6 carbon atoms; R4 represents an alkylene group having 1-6 carbon atoms, a cycloalkylene group having 3-8 carbon atoms which may contain a double bond, or an arylene group having 6-10 carbon atoms; and a represents a positive integer of 1-20); another radically polymerizable monomer; and a photochromic compound. According to the present invention, it becomes possible to produce a lens which does not undergo the surface hazing caused by bleed out or the delamination during the process of the production thereof, has excellent durability, and can exhibit high photochromic performance.
