Beschreibung
Zusammenfassung:	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.
