ABSTRACT:
A fluorescent article is disclosed comprising a polymer matrix comprising a polymer having in its backbone repeating units of a U.V. light absorbing moiety, or a moiety capable of being transformed by photo-Fries rearrangement into a U.V. light absorbing moiety, the matrix further comprising a fluorescent dye. The matrix affords surprisingly improved fluorescence protection as compared to prior fluorescent articles having only U.V. light absorbing additives.
