Fluorescent polymeric articles having screening layer formed from U.V. light absorbing polymer |
摘要 |
A fluorescent article is disclosed in which a U.V. light screening layer 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, is disposed in operative screening relation to a layer containing a fluorescent colorant. The U.V. light screening layer affords surprisingly improved fluorescence protection as compared to prior U.V. light screening layers having only U.V. light absorbing additives.
