Title:
TRISARYL-1,3,5-TRIAZINE ULTRAVIOLET LIGHT ABSORBERS CONTAINING HINDERED PHENOLS
Document Type and Number:
WIPO Patent Application WO1999067223
Kind Code:
A3
Abstract:
This invention relates generally to hindered phenol-substituted triazines and the use thereof to protect materials such as coatings, polymers, resins, organic compounds and the like against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of hindered phenol-substituted triazines includes a trisaryl-1,3,5-triazine in which one of the aryl groups is substituted by a group which comprises a hindered phenol or is a hindered phenol and is further substituted by a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine. These materials may, under the appropriate circumstances, form oligomers. A method for stabilizing a material by incorporating such hindered phenol-substituted triazines is also disclosed.
