COUMESTAN-LIKE ANTIOXIDANTS AND UV ABSORBANTS

The present invention relates to derivatives of the 1H-pyrano[4,3-b]benzofuran-1-one structure and their nitrogen analogues which possess powerful antioxidant properties combined with a highly effective UV absorbing functionality in one molecule. These compounds are especially useful in cosmetical and dermatological formulations.

Process for making 2-hydroxy-4-alkoxyphenyl or 2,4-dihydroxyphenyl substituted 1,3,5-triazine UV absorbers

The invention provides new processes for preparing compositions containing at least one triazine compound, including new compounds for use in these processes to form the compositions and the new compositions that are formed.

Hydroxy-substituted N-alkoxy hindered amines and compositions stabilized therewith

Hindered amines substituted on the N-atom with an hydroxy-substituted alkoxy moiety are particularly effective in stabilizing organic polymer compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not otherwise attainable.

Substituted 5-heteroaryl-2-(2-hydroxyphenyl)-2h-benzotriazole UV absorbers, a process for preparation thereof and compositions stabilized therewith

Compounds of formula I or II where R is a heteroaryl moiety, such as 3-pyridyl, or T is a heteroaryl moiety, such as thien-2,5-diyl, and E1and E2are 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 heteroarylboronic 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.

Red-shifted tris-aryl-S-triazines

Tris-aryl-s-triazines of formula V STR1 which contain from one one to three resorcinol derived moieties with at least one of said moieties substituted in the 5-position with a group such as, for example, alkyl or phenylalkyl have UV spectra which are red-

Reactive, non-yellowing triazine compounds useful as UV screening agents for polymers

Triazine compounds are disclosed which are useful for imparting UV screening properties to polymers of the formula: STR1 wherein R is an electron withdrawing group; R1 is H, STR2 where R3 is an alkyl group having from one to about si
