  Sterically hindered alkoxyamine and hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of the formula where for example E and E’ are 2-hydroxycydohexyloxy, 2-hydroxy-2-methylpropoxy, benzyloxy, methoxy, propoxy, hexyloxy, heptyloxy, oclyloxy or cyclohexyloxy, Rx is for example -NH2+CH2CH20H Cl-, -NH3+ -OAc, =NOH, -NHCH(CH3)COO-K+,- NHCH2CH2NH(CH3)2+ -OAC, -NHCH2CH2SO3-K+, -NHCH(COO- K+)CH2CH2SCH3, -NHCH2COO- K+, -OCH(CH3)COO-K+, -OCH2CH2NH(CH3)2+ -OAC, -OCH2CH2SO3-K+, -OCH(COO- K+)CH2CH2SCH3 or -OCH2COO-K+, and where R5 comprises repeating units of -(OCH2CH2)-, -(OCH2CH2(CH3))-,-(CH2CHCOOH)-, -(CH2C(CH3)COOH)-, -(CH2CHCOOCH3)-, -(NHCH2CH2)-, -(CH2CHOH)-, -(CH2CHCONH2)-or -(CH2CH(NHCOH))-. These compounds are particularly effective in stabilizing aqueous polymer systems against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are effective for example in stabilizing water borne coatings, aqueous inks, aqueous inkjet media and photocured aqueous systems.

  Provided is a process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzo ring, for example a trifluoromethyl group, which involves diazotizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means. Also provided is a novel one-pot, multiphase reaction for the preparation of 2(2-nitrophenylazo) substituted phenols, which are precursors for 2H-benzotriazole UV absorbers.

• Carboxylic acid esters of zosteric acid for prevention of biofouling

  Carboxylic acid ester derivatives of zosteric acid are effective in preventing biofouling and are readily formulated into coatings or films. Coating or film compositions of the esters, and methods for their application, are provided which reduce the dissolution of the esters into water or loss to the environment. The Zosteric acid esters of the invention appear to function by preventing adhesion of an organism to a surface rather than by acute toxic activity rendering said compositions more environmentally acceptable.

  Zosteric酸的羧酸酯衍生物在防止生物污垢方面非常有效，并且很容易制成涂层或薄膜。本发明提供了酯的涂层或薄膜组合物以及其应用方法，其减少了酯在水中的溶解或对环境的损失。本发明的Zosteric酸酯似乎通过防止生物附着在表面上而不是通过急性毒性活性来发挥作用，从而使这些组合物更具环境可接受性。
