摘要:
To provide a photochromic composition which functions as an adhesive layer for bonding two optical sheets that are formed of a polycarbonate resin or the like, so that a laminate that is obtained by bonding two optical sheets with the composition being sandwiched therebetween has excellent adhesion, heat resistance and photochromic properties. In particular, to provide a photochromic composition which is capable of forming an adhesive layer that is not decreased in the adhesion between the optical sheets even in cases where the adhesive layer is in contact with hot water. Provided is a photochromic composition which contains a urethane polymer having a polymerizable group (component A) and a photochromic compound (component B).

Provided is a photochromic composition which can function as an adhesive layer for bonding optical sheets made from a polycarbonate resin or the like and a laminated article using said composition exhibits excellent tight adhesion, heat resistance and photochromic properties. In particular, provided is a photochromic composition which can prevent an elution of the composition from the optical sheets when embedding and polymerizing in a polymerizable monomer. The photochromic composition comprises a polyurethane resin (A) having an isocyanurate structure and a photochromic compound (B).

摘要:
A primer coating composition is provided for an optical article capable of forming a coating layer having excellent impact resistance, abrasion resistance, and adhesion to various kinds of plastic materials without occurring of appearance faulty for an optical base material, for example, a plastic lens for an eyeglass. A primer composition for an optical article comprises; (A) aqueous dispersion of urethane resin having a polycarbonate-derived skeleton and the elongation of 200˜1000%; (B) an organic solvent having 3˜9 carbon atoms and having an ether bond or carbonyl bond and one hydroxyl group in a molecule; and (C) lower alcohol having 1˜4 carbon atoms, wherein the weight ratio of said organic solvent to said lower alcohol is from 0.01 to less than 2.00.
