ABSTRACT:
Compounds of the formulae I and II ##STR1## in which A is a radical of the formulae III, IV or V ##STR2## R.sub.1 and R.sub.4 are --H or --Cl, R.sub.2 and R.sub.5 are --H, halogen, --NO.sub.2, --CN, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 alkoxy, --CF.sub.3 or phenyloxy which is unsubstituted or substituted by one or two chlorine atoms and/or one or two methyl or methoxy groups, and R.sub.3 is alkyl having at least 10 C atoms, X is a radical of the formulae --NH--, --O--, ##STR3## n is the number 1 or 2, Y is the radical of the formulae --COO--, --OOC--, --CONH-- or --NHCO-- or a radical of the formulae ##STR4## in which R.sub.1 and R.sub.2 are as defined above, D is an aromatic heterocyclic 5- or 6-membered ring, in which the ring contains 1 or 2 N atoms and may additionally contain an O atom or S atom, Z is --H, --Br, --OCH.sub.3, --CN or --NO.sub.2 and X.sub.1 and X.sub.2, independently of one another, are --H, halogen, --CH.sub.3, --OCH.sub.3, --OC.sub.2 H.sub.5 or --NO.sub.2 and X.sub.3 is --H, --NHCO--C.sub.1 -C.sub.4 alkyl, benzoylamino or phenylcarboxamide which are each unsubstituted or substituted on the phenyl ring by one or two chlorine atoms and/or one or two methyl or methoxy groups or an --NHCO--C.sub.1 -C.sub.4 alkyl group, or X.sub.2 and X.sub.3 together with the carbon atom to which they are bound are an aromatic carbocyclic 6-membered ring or an aromatic heterocyclic 5- or 6-membered ring, in which the heterocyclic ring contains 1 or 2 N atoms and can additionally have an O atom or S atom, and Y.sub.1 is --H, --OCH.sub.3, --OC.sub.2 H.sub.5 or --NHCOCH.sub.3, with the proviso that X.sub.3 must not be H, if X is --O-- or --NH--, are highly suitable for the mass coloration of plastics, in particular of polyolefins.
