Amide functional ultraviolet light absorbers for polyurethanes and polyureas |
| abstract |
An ultraviolet light absorbing materials that resists blooming and migration is made up of a polyurethane or polyurea polymer 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 a retroreflective sheetings and conformable marking sheets. |
