ABSTRACT:
Isoindoline derivatives monosubstituted in the 1-position corresponding to the general formula ##STR1## in which the cyclic radical R is an aromatic ring, a substituted aromatic ring, a tetrahydrogenated aromatic ring, a nitrogen-containing heterocyclic ring, or a sulfur-containing heterocyclic ring, and R.sub.1 is a substituent represented by the general formula ##STR2## where Y is an atom of oxygen, nitrogen, sulfur, or carbon, Z is the atom or atoms necessary to form a 5-membered or 6-membered heterocyclic ring which may have a fused-on aromatic ring selected from phenyl and naphthyl groups, R.sub.2 is an alkyl, sulfoalkyl, or carboxyalkyl radical, and X.sup.- is the anion for the cationic quaternary nitrogen. The derivatives are dyes having hydrophilic properties. They are useful for dyeing and printing textile fibers and for photographic applications.
