Monoazo compounds containing long-chain alkyl radicals
Compounds of the formulae I and II STR1 in which A is a radical of the formulae III, IV or V STR2 R1 and R4 are –H or –Cl, R2 and R5 are –H, halogen, –NO2, –CN, C1 -C4 -alkyl, C1 -C4 alkoxy, –CF3 or phenyloxy which is unsubstituted or substituted by one or two chlorine atoms and/or one or two methyl or methoxy groups, and R3 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 R1 and R2 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, –OCH3, –CN or –NO2 and X1 and X2, independently of one another, are –H, halogen, –CH3, –OCH3, –OC2 H5 or –NO2 and X3 is –H, –NHCO–C1 -C4 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–C1 -C4 alkyl group, or X2 and X3 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 Y1 is –H, –OCH3, –OC2 H5 or –NHCOCH3, with the proviso that X3 must not be H, if X is –O– or –NH–, are highly suitable for the mass coloration of plastics, in particular of polyolefins.
