    CPC classification number: C09B43/34

    Abstract: AZO DYESTUFFS FREE FROM SULFONIC ACID GROUPS ARE PREPARED WHICH ARE VALUABLE NEW PIGMENT DYESTUFFS CHARACTERIZED BY GOOD FASTNESS TO LIGHT, SOLVENTS AND MIGRATION, AND BY A GOOD THERMAL STABILITY ADAPTED FOR USE IN COLORING PAPERS, LACQUERS, AND SYNTHETIC MATERIALS AND FOR PRODUCING PIGMENT PASTE AND PRINTING INKS. THE DYESTUFFS CORRESPOND TO THE GENERAL FORMULA

    2-((1,3-DI(O=),(K1-N=N-),(R)M-ISOINDOLIN-2-YL)-NH-V-NH-),

    WHERE V STANDS FOR A RADICAL-OC-B-CO-OR A RADICAL

    1,3-DI(O=),(K1-N=N-),(R)M-ISOINDOLINE

    WHERE B DENOTES A DIRECT BOND, AN OPTIONALLY SUBSTITUTED ALIPHATIC, ARALIPHATIC, CARBOCYCLIC OR HETEROCYCLIC RADICAL, X STANDS FOR NH, O OR S; K1 DENOTES THE RADICAL OF A MONOFUNCTIONAL COUPLING COMPONENT; R STANDS FOR IDENTICAL OR DIFFERENT SUBSTITUENTS; AND M IS AN INTEGER FROM 0 TO 3.
