Abstract
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 generated by curing a (meth)acrylate-based polymerizable composition containing a photochromic compound in this order, in which the polymerizable composition for forming the primer layer contains a component A: polyisocyanate and a component B: hydroxy group-containing (meth)acrylate.
