US Classification:

524/590000

Abstract:

An aqueous polyurethane dispersion and thermosetting compositions containing them. The aqueous polyurethane dispersion includes an aqueous medium with dispersed polyurethane-acrylate particles, which include the reaction product obtained by polymerizing a pre-emulsion formed from hydrophobic polymerizable ethylenically unsaturated monomers, a crosslinking monomer, and an active hydrogen-containing polyurethane acrylate prepolymer, which is a reaction product obtained by reacting a polyol, a polymerizable, ethylenically unsaturated monomer containing at least one hydroxyl group, a compound that includes an alkyl group having at least one hydroxyl group and optionally a carboxylic acid group, and a polyisocyanate. The prepolymer includes at least 30 percent by weight of polyurethane acrylate prepolymers with at least one terminal ethylenic unsaturation at one end of the molecule, and at least one active hydrogen-containing group at the opposite end; and at least 10 percent by weight of prepolymers having at least one terminal ethylenic unsaturation at each end of the molecule.

Abstract:

The present invention relates to photochromic materials that include one or more indeno-fused naphthopyrans that have particular groups at the 7, 11, and 13 positions thereof, and at the position alpha to the oxygen of the pyran ring thereof. With some embodiments, hydrogen or an alkoxy group is bonded to the 7 position, an optionally substituted phenyl is bonded to the 11 position, two alkyl groups are bonded to the 13 position, and two optionally substituted phenyl groups are bonded to the position alpha to the oxygen of the pyran ring of the indeno-fused naphthopyran compound. The 13 position of the indeno-fused naphthopyrans is free of ether groups in which an ether oxygen is bonded to the 13 position, and hydroxyl. The present invention also relates to photochromic articles and compositions that include such indeno-fused naphthopyrans.
