ABSTRACT:
Blocked benzotriazoles of the formula I or II ##STR1## where x is 1 or 2, R.sup.1 in the case of x=1 and in the formula II is an acyl group of the formula --CO--R.sup.5, a sulfonyl group of the formula --SO.sub.2 --R.sup.6, a phosphoryl group of the formula --P(O).sub.r (R.sup.14)(R.sup.15), and in the case of x=2 is --CO-- or a diacyl group of the formula --CO--CO-- or --CO--R.sup.7 --CO--, and R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.14 and R.sup.15 have the meanings defined in claim 1, are crypto light stabilizers which can be activated by short-wave irradiation. Their use in coating materials is of interest in cases in which light stabilizers containing the free OH compounds have disadvantages with regard to their application.
