    摘要: 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. 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.

    摘要: The s-triazines of formula I are UV absorbers having high thermal stability and surprisingly high extinction coefficients making them of especial value for stabilizing polymer subsnates, especially automotive coatings. Tris-aryl-s-triazines in which at least one of the aryl groups has an hydroxy group ortho to the point of attachment to the triazine ring are well known UV absorbers. It is also well-known that this class of triszines protect organic polymers from the deleterious effects of exposure to actinic radiation. The instant invention pertains to novel dimetic or oligomeric tris-aryl-s-triazines wherein at least one of the aryl groups is a biphenylyl or substituted biphenylyl moiety. More particularly, the instant invention relates to compounds of formula I ##STR1## wherein G.sub.1, G.sub.2, and E.sub.2 are here-in-below defined.
