Abstract

N-Vinyl-containing glycoluril derivatives I ##STR1## where R.sup.1 and R.sup.2 independently of one another are each hydrogen, C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.8 -cycloalkyl, phenyl, tolyl or C.sub.7 -C.sub.12 -phenylalkyl or PA0 R.sup.1 and R.sup.2 together form a tri-, tetra- or pentamethylene group, PA0 R.sup.3 to R.sup.6 are each C.sub.1 -C.sub.4 -alkyl, PA0 R.sup.7 is hydrogen, C.sub.1 -C.sub.8 -alkyl, cyano or a radical of the formula COOR.sup.9, PA0 R.sup.8 is cyano or a radical of the formula COOR.sup.9 and PA0 R.sup.9 is C.sub.1 -C.sub.12 -alkyl, C.sub.5 -C.sub.8 -cycloalkyl, phenyl, tolyl or C.sub.7 -C.sub.12 -phenylalkyl, are suitable as light stabilizers and stabilizers for organic material, in particular for plastics and coatings.
