  • Patent number: 6515051
    Abstract: Benzotriazole UV absorbers which are substituted at the 5-position of the benzo ring by an electron withdrawing group exhibit enhanced durability and very low loss rates when incorporated into automotive coatings. This is particularly the case when the 3-position of the phenyl ring is also substituted by phenyl or phenylalkyl such as &agr;-cumyl. Compounds where the 5-position of the benzo ring are substituted by perfluoroalkyl such as trifluoromethyl are particularly of interest for both their enhanced durability and for their excellent solubility and excellent color properties in some thermoplastic compositions when the phenyl ring is substituted at the 3-position by hydrogen or tert-alkyl.

  • Patent number: 5824721
    Abstract: This invention provides an aromatic or cycloaliphatic triazole-based chemical embossing inhibitor which is completely soluble in water and compatible with water-based printing inks for use in producing textured foamed plastic surfaces. The triazoles comprise a general class of mono- and multi-functional 1-N substituted aminomethyl derivatives which are rendered soluble in water by the presence of at least one polyethyleneoxide (PEO) oligomer chain, or polypropylene (PPO)-polyethyleneoxide copolymer oligomer chain or PPO/PEO/PPO triblock oligomer chain with a sufficiently high PEO/PPO ratio for water solubility. Preferably the triazole derivative has at least six polyethylene oxide monomer moieties per triazole moiety.
