ABSTRACT:
An ultraviolet light absorbing material that resists blooming and migration is made up of a fluoropolymer and an amide functional ultraviolet light absorbing compound, wherein the polymer and the amide functional ultraviolet light absorbing compound are hydrogen bonded to one another. Polymeric films that contain a polymeric matrix and the ultraviolet light absorbing material are useful as the top layer in multilayer constructions such as retroreflective sheetings and conformable marking sheets.
