Publication number: 20030065066Abstract: A novel class of UV absorbers, ortho-hydroxyphenyl substituted triazine compounds bonded to aminoplast resins is provided. Compared to unanchored stabilizers, the anchored stabilizers disclosed herein have increased compatibility with coating resins and have reduced volatility due to higher molecular weights resulting from anchoring. A process for preparing the anchored stabilizers by the reaction of triazines containing active hydrogen with alkoxymethylated aminoplasts in the presence of a catalytic amount of acid. The novel ortho-hydroxylphenyl substituted triazine compounds are bound to the aminoplast resins by carbon-oxygen, carbon-carbamoyl nitrogen or carbon-active methylene carbon linkages.
