Amide functional ultraviolet light absorbers for polyurethanes and polyureas |
| abstract |
The present invention relates to an ultraviolet absorbing material that is resistant to emissions and migration, consisting of polyurethane and polyurea polymers and an amide functional ultraviolet absorbing compound, wherein the polymer and amide functional ultraviolet absorbing compound are hydrogen bonded to each other. Polymer films comprising a polymer matrix and an ultraviolet absorbing material are useful as top layers in multilayer structures such as retroreflective sheets and conformable label sheets. |
