Abstract
Official abstract text for this publication.
Provided is an optical article having a substrate, a primer layer generated by curing a polymerizable composition for forming the primer layer, and a photochromic layer containing a photochromic compound in this order, in which the polymerizable composition for forming the primer layer contains a component A: a polyisocyanate, a component B: a hydroxy group-containing polymerizable compound, and a component C: a polymerizable compound having a viscosity of 100 cP or less and being selected from the group consisting of (meth)acrylates and vinyl ethers.
First claim
Opening claim text (preview).
What is claimed is: 1 . An optical article that is a spectacle lens, the spectacle lens comprising: a substrate; a primer layer generated by curing a polymerizable composition for forming the primer layer; and a photochromic layer containing a photochromic compound in this order, wherein the polymerizable composition for forming the primer layer consists essentially of a component A: a polyisocyanate, a component B: a hydroxy group-containing polymerizable compound, a component C: a polymerizable compound having a viscosity of 100 cP or less and being selected from the group consisting of (meth)acrylates and vinyl ethers, and a polymerization initiator. 2 . The optical article according to claim 1 , wherein a content rate of the component C of the polymerizable composition for forming the primer layer is, with respect to a total of the component A, the component B and the component C, 30.0% by mass or more and 90.0% by mass or less. 3 . The optical article according to claim 1 , wherein, in the polymerizable composition for forming the primer layer, the component C is, among the component A, the component B and the component C, a component having a largest fraction. 4 . The optical article according to claim 1 , wherein the number of the hydroxy groups contained in one molecule of the component B is 2 or more. 5 . The optical article according to claim 1 , wherein the component B is a hydroxy group-containing (meth)acrylate. 6 . The optical article according to claim 5 , wherein the component B is a bi- or higher functional (meth)acrylate. 7 . Spectacles comprising: the spectacle lens according to claim 1 .
