This invention relates to novel UV absorbers, their methods of preparation, their use in stabilizing polymers and polymers so stabilized against the degradative effects of UV light. The novel compounds of formula I are oxamides which are substituted on one or both nitrogens with
a 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl group. The 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl groups are efficient UV absorbing groups and the oxamide group contributes additional light stabilizing, heat stabilizing and metal complexing properties to the compounds. The compounds have low-volatility and are especially useful as UV stabilizers for engineering resins processed at high temperatures.
The present invention relates to novel substituted cyclohexyl monohydric alcohols possessing woody odor which are useful as fragrance materials. The invention also provides method for synthesis of the above compounds. The invention also provides fragrance compositions which utilize the compounds of the invention to impart woody aroma to such compositions.
The compounds of the invention have the general formula as under
