Isoindoline dyes, their preparation and use
 Novel dyes of the formula ##STR1## where A is cyano, carbo-C.sub.1 -C.sub.4 -alkoxy, carbamyl, N-C.sub.1 -C.sub.4 -alkylcarbamyl, N-phenylcarbamyl, acetyl, benzoyl, 4-nitrophenyl or 4-cyanophenyl, PA0 X is hydrogen, chlorine, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, and if n is 2 the substituents may be identical or different, PA0 n is 1 or 2, PA0 R.sup.1 is hydrogen, methyl, ethyl or 2-hydroxyethyl and PA0 R.sup.2 is phenyl or cyclohexyl, or PA0 R.sup.1 is hydrogen and PA0 R.sup.2 is C.sub.1 -C.sub.4 -alkyl, or PA0 R.sup.1 and R.sup.2 are C.sub.1 -C.sub.6 -alkyl, allyl or phenyl-C.sub.1 -C.sub.4 -alkyl or PA0 the group ##STR2## is a saturated heterocyclic five-membered or six-membered ring which may additionally contain an oxygen or a further nitrogen as ring members, PA0 Y is hydrogen, hydroxyl, methyl or ethyl; ##STR3## where R.sup.3 is linear or branched C.sub.1 -C.sub.12 -alkyl, or is phenyl; ##STR4## where R.sup.4 is hydrogen or C.sub.1 -C.sub.4 -alkyl and R.sup.5 is hydrogen, linear or branched C.sub.1 -C.sub.12 -alkyl or trifluoromethyl; chloromethyl; C.sub.1 -C.sub.4 -alkoxymethyl, phenoxymethyl, benzyl, phenylethyl, C.sub.3 -C.sub.7 -cycloalkyl, phenyl, H.sub.5 C.sub.6 --CH.dbd.CH-- or --CH.sub.2 --PO(OR.sup.6).sub.2, where R.sup.6 is C.sub.1 -C.sub.4 -alkyl; or ##STR5## where R.sup.7 is C.sub.1 -C.sub.12 -alkyl, phenyl or C.sub.1 -C.sub.12 -alkylphenyl; or Y is N-C.sub.1 -C.sub.4 -alkylamino if R.sup.1 and R.sup.2 are C.sub.1 -C.sub.4 -alkyl, or Y is N,N-di-C.sub.1 -C.sub.4 -alkylamino, N-pyrrolidinyl, N-piperidinyl or N-morpholinyl if ##STR6## has the same meaning, and Z is hydrogen or, if R.sup.1 and R.sup.2 are C.sub.1 -C.sub.4 -alkyl or allyl and Y is ##STR7## Z is hydrogen, methoxy or ethoxy, and alkyl, phenyl, phenoxy and phenylthio may contain additional substituents. The dyes give blue to violet hues on synthetics, in particular on linear polyester fibers. Where Z is methoxy or ethoxy, greenish blue dyeings are obtained. The dyeings are very deep, clear and brilliant. Some of the dyes may also be used for the mass coloring of thermoplastics.
