Tetraalkylpiperidinyl substituted uracil derivatives and their use as ultraviolet light stabilizers

摘要

Tetraalkylpiperidinyl substituted uracil derivatives are disclosed which can be represented by the formula <IMAGE> wherein each R' is independently an alkyl radical, n is 1 or 2 and R is a substituted or unsubstituted aliphatic radical, cycloaliphatic radical, aromatic radical or aromatic-aliphatic radical. These derivatives are useful as UV light stabilizers in synthetic resins.
