摘要： The present invention is directed towards novel sulfonic acid esters as catalysts for crosslinking of polymers having hydroxyl, carboxyl, and amide functional groups with a crosslinking agent and resin compositions containing the same. The present invention provides polymeric film coatings which have superior hardness, impact resistance, adhesion, improved blister resistance, salt spray characteristics and flexibility. These catalysts are especially effective in coil primer formulations containing calcium ion exchange anticorrosive pigments, where traditional blocked acid catalysts are ineffective.

摘要： This invention relates to lubricating oil additives, and to lubricating oil compositions, their method of preparation, and use. More specifically, this invention relates to several novel lubricating oil additives and compositions which contain a tungsten compound and an antioxidant, namely aminic antioxidants such as a secondary diarylamine or an alkylated phenothiazine. The use of the tungsten compound with the secondary diarylamine and/or the alkylated phenothiazine provides improved oxidation and deposit control to lubricating oil compositions. The lubricating oil compositions of this invention are particularly useful as crankcase and transmission lubricants, gear oils and other high performance lubricant applications.

摘要： Photo-curable coating formulations which comprise a durable and/or red-shifted reactable hydroxyphenylbenzotriazole ultraviolet light absorber (UVA) are effectively photocured employing a combination of α-hydroxy ketone and bisacylphosphine oxide photoinitiators. The reactable UVA's are reacted into the coating upon curing. The combination of the photoinitiators bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide and 1-hydroxycyclohexylphenylketone is especially effective for this purpose.
