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