Abstract: A water-insoluble monoazomethine dyestuff of the formula
WHEREIN Ar is an aromatic or heterocyclic radical which contains at least one substituted sulfonic acid amide group, an optionally substituted carboxylic acid amide, acylamino, sulfonylamino, urea, carboxylic acid or laked sulfonic acid group or a -NHCOgroup contained in a heterocyclic ring, and wherein the benzene nucleus a may contain substituents which are valuable pigments, especially suitable for printing pastes. They may also be used for the pigmentation of high-molecular organic material, for example of cellulose ethers and esters, polyamides, polyurethanes or polyesters, acetyl cellulose, nitro cellulose and natural or synthetic resins, for polyolefins, rubber, casein, silicon and silicon resins, individually or in mixture with one another. The new pigments are characterized by high fastness properties and especially have a considerably improved fastness to light and to solvents.
