Abstract
A composition of matter contains as a principal component a material which acts as an ultraviolet light stabilizer. The ultraviolet light stabilizer is formed from the reaction of (a) a methylol or alkoxy alkyl-containing material, and (b) an alkyl substituted piperidine containing material which is represented by the following structural formula: ##STR1## R" is hydrogen or C.sub.1 to C.sub.6 alkyl, R.sub.10 is hydrogen or methyl, PA1 Y is a radical derived from a material selected from the group consisting of amino substituted triazines, ureas, glycolurils, phenols, and amides of the formula ##STR2## R' is hydrogen or C.sub.1 to C.sub.12 alkyl and R is an aliphatic, cycloaliphatic, or olefinic radical, or an acrylic polymer moiety having at least one group selected from hydroxyl, carboxyl, amido, and ureido, said reaction proceeding between a methylol or alkoxy alkyl group of (a) and the group selected from hydroxyl, carboxyl, amido and ureido of (b).
