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 or mixtures of s-triazine UV absorbers. An example of such compounds is 2,4-bis(2,4-dimethylphenyl)-6-[2-hydroxy-4-(3-nonyloxy*-2-hydroxypropyloxy )-5-.alpha.-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.
