Provided is a photochromic optical article obtained by bonding a pair of optical article plates to each other with an adhesive layer that contains (A) a photochromic compound and (B) a urethane resin, wherein (B) the urethane resin is obtained by polymerizing: (B1) a polyiso(thio)cyanate compound having two or more iso(thio)cyanate groups in a molecule; (B2) a poly(thi)ol compound having, in a molecule, two or more active hydrogen-containing groups selected from a hydroxyl group and a thiol group; and (B3) a mono(thi)ol compound having, in a molecule, one active hydrogen-containing group selected from a hydroxyl group and a thiol group. Also provided is a method for manufacturing the photochromic optical article.
本发明提供了一种光致变色光学制品,通过将一对光学制品板用含有(A)光致变色化合物和(B)氨基甲酸乙酯树脂的粘合剂层相互粘合而获得,其中(B)氨基甲酸乙酯树脂通过聚合获得:(B1)分子中具有两个或两个以上异(硫)氰酸酯基团的聚异(硫)氰酸酯化合物;(B2)分子中具有两个或两个以上选自羟基和硫醇基团的活性含氢基团的聚(硫)醇化合物;以及(B3)分子中具有一个选自羟基和硫醇基团的活性含氢基团的单(硫)醇化合物。此外,还提供了一种制造光致变色光学制品的方法。
