Abstract: The contents of clear or lightly colored plastic containers or films are protected from ultraviolet radiation by the incorporation of certain UV absorbers of the class of durable benzotriazoles and tris-aryl-s-triazines in the container or film. Contents to be protected include foodstuffs, beverages, pharmaceuticals, cosmetics, personal care products, shampoos and the like.

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: Adhesive compositions are rendered stable against degradation caused by ultraviolet light through the incorporation of a highly soluble, photostable benzotriazole UV absorber which is substituted in the ortho position of the hydroxyphenyl ring by &agr;-cumyl or phenyl. Examples of such compounds are 2-(2-hydroxy-3-&agr;-cumyl-5-tert-octylphenyl)-2H-benzotriazole, 5-chloro-2-(2-hydroxy-3-&agr;-cumyl-5-tert-octylphenyl)-2H-benzotriazole, 5-fluoro-2-(2-hydroxy-3-&agr;-cumyl-5-tert-octylphenyl)-2H-benzotriazole, 2-(2-hydroxy-3-&agr;-cumyl-5-tert-butylphenyl)-2H-benzotriazole, 5-chloro-2-(2-hydroxy-3-&agr;-cumyl-5-tert-butylphenyl)-2H-benzotriazole and 5-fluoro-2-(2-hydroxy-3-&agr;-cumyl-5-tert-butylphenyl)-2H-benzotriazole. These compounds exhibit excellent photostability and are highly soluble in adhesive formulations.

Abstract: Adhesive compositions are rendered stable against degradation caused by ultraviolet light through the incorporation of a highly soluble, high extinction, photostable hydroxyphenyl-s-triazine UV absorber. An example of such compounds is 2,4-bis(2,4-dimethylphenyl)-6-[2-hydroxy-4-(3-nonyloxy*-2-hydroxypropyloxy)-5-&agr;-cumylphenyl]-s-triazine (* denotes a mixture of octyloxy, nonyloxy and decyloxy groups). Such compounds exhibit high extinction, excellent photostability and are highly soluble in adhesive formulations. The laminated articles derived from these compositions include, for example, solar control films, films and glazings, UV absorbing glasses and glass coatings, windscreens, retroreflective sheetings and signs, solar reflectors, optical films and the like.

Abstract: Adhesive compositions are rendered stable against degradation caused by ultraviolet light through the incorporation of selected highly soluble, red-shifted, photostable benzotriazole UV absorbers which absorb light strongly in the 350 to 400 nm range. These UV absorbers exhibit excellent photostability and are highly soluble in adhesive formulations. The laminated articles derived from these compositions include, for example, solar control films, films and glazings, UV absorbing glasses and glass coatings, windscreens, retroreflective sheetings and signs, solar reflectors, optical films and the like.

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.
