  • Polymerizable water-soluble or alcohol-soluble ultraviolet absorber
    Patent number: 7915322
    Abstract: The present invention relates to a polymerizable water-soluble or alcohol-soluble ultraviolet absorber, which is represented by the following formula (I): wherein R1 is H or C1˜5 alkyl; R2 is H, Cl, Br or I; R3 is H or methyl; and m each is an integer in the range from 3 to 12. The above-mentioned compounds are suitable for copolymerizing with one or more monomers to form copolymers so that the UV-light resistance of the copolymer can be efficiently promoted.
