Abstract

Abstract Translated from German Blockierte Benztriazole der Formel I oder II <IMAGE> worin x 1 oder 2 ist, R1 im Falle von x = 1 und in Formel II eine Acylgruppe der Formel -CO-R<5>, eine Sulfonylgruppe der Formel -SO2-R<6>, eine Phosphorylgruppe der Formel -P(O)r(R¹<4>)(R¹<5>) und im Falle von x = 2 -CO- oder eine Diacylgruppe der Formel -CO-CO- oder CO-R<7>-CO bedeutet, und R², R³, R<4>, R<5>, R<6>, R<7>, R¹<4>, R¹<5> die in Anspruch 1 definierte Bedetung haben, sind Kryptolichtsschutzmittel, die durch kurzwellige Bestrahlung aktiviert werden können. Ihre Verwendung in Überzugsmitteln ist in solchen Fällen von Interesse, in denen die freihen OH-Verbindungen applikatorische Nachteile haben. Blocked benzotriazoles of the formula I or II <IMAGE> in which x is 1 or 2, R1 in the case of x = 1 and in formula II an acyl group of the formula -CO-R <5>, a sulfonyl group of the formula -SO2-R <6 >, a phosphoryl group of the formula -P (O) r (R¹ <4>) (R¹ <5>) and in the case of x = 2 -CO- or a diacyl group of the formula -CO-CO- or CO-R <7 > -CO means and R², R³, R <4>, R <5>, R <6>, R <7>, R¹ <4>, R¹ <5> have the condition defined in claim 1, are cryptolight protection agents, which can be activated by short-wave radiation. Their use in coating compositions is of interest in cases in which the free OH compounds have application disadvantages.
