Abstract: Sterically hindered hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of formulae (5)-(7) 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 ink jet media and photocured aqueous systems.

Abstract: The present invention relates to novel ultraviolet light absorbers of the benzoxazinone, oxanilide, benzylidene malonate, quinazoline and benzotriazole classes. The invention also relates to polymer and photographic compositions stabilized against the deleterious effects of light induced degradation which comprise the novel ultraviolet light absorbers.

Abstract: Compounds of formula I or II where R is an aryl moiety, such as phenyl, naphthyl or biphenylyl, or is phenyl substituted by one or more trifluoromethyl, bromo or cyano, and E1 and E2 are independently hydrogen, alkyl, aralkyl and the like are prepared by reaction of a benzotriazole substituted on the 5-position of the benzo ring by a halogen atom with a arylboronic acid or ester in the presence of a transition-metal catalyst, such as palladium (II) diacetate. The benzotriazole compounds of formula I are particularly efficacious as stabilizers for automotive coatings and candle wax.

Abstract: Sterically hindered N-hydrocarbyloxyamines are prepared from hindered amine N-oxyl compounds by a process which uses hydrogen peroxide or a hydrogen peroxide equivalent, a catalytic amount of a peroxide decomposing transition metal salt, metal oxide, or metal-ligand complex, a hydrocarbon solvent containing no activated hydrogen atoms, and a relatively inert cosolvent. These compounds are useful as thermal and light stabilizers for a variety of organic substrates.
