This invention relates to copolymerizable ultraviolet light absorber compounds having the formula:
where R is alkyl C1-C6; and
Y is a copolymerizable radical selected from acryloyl C3-C12, acryloxyalkyl C3-C12, acryloxyhydroxyalkyl C3-C12, alkylacryloxyhydroxyalkyl C3-C12, and -R'CR"=CHR"', where
R' is alkylene, C1-C10, oxyalkylene, C1-C10, alkyleneoxyal- kylene, C1-C10 or phenylene, C1-C10, unsubstituted or substituted with hydroxy; and
R" and R"' are independently hydrogen or alkyl, C1-C6.
本发明涉及可共聚的紫外线吸收剂化合物,其式如下
其中 R 为 C1-C6 烷基;以及
Y 是选自丙烯酰 C3-C12、丙烯酰氧基烷基 C3-C12、丙烯酰氧基羟基烷基 C3-C12、烷基丙烯酰氧基羟基烷基 C3-C12,以及 -R'CR"=CHR"' 的可共聚基,其中
R' 是未取代或被羟基取代的 C1-C10 亚烷基、C1-C10 氧代亚烷基、C1-C10 亚烷基氧代亚烷基或 C1-C10 亚苯基;以及
R" 和 R"' 独立地为氢或 C1-C6 烷基。
