Abstract: A PERYLENE SERIES DYESTUFF OF THE FORMLUA:

2,9-BIS(R1-N(-R2)-)-1H,10H-ANTHRA(2,1,9-DEF:6,5,10-

D''E''F'')DIISOQUINOLINE-1,3(2H),8(9H),10-TETRAONE

WHEREIN: R1 IS HYDROGEN, AN OPTIONALLY SUBSTITUTED ALKYL, CYCLOALKYL, ARALKYL, OR ARYL GROUP; R2 IS A OPTIONALLY SUBSTITUTED ALKYL, CYLOALKYL, ARALKYL OR ARYL GROUP, OR AN ALKOXY CABONYL GROUP, OR A HEETEROCYCLIC RADICAL; OR A RADIACAL OF THE FORMULA: WHEREIN X IS

-X-R3, -CO- OR -SO-

AND R3 IS AN OPTIONALLY SUBSTITUTED ALKYL, CYUCLOALKYL, ARALKYL, ARYL OR HETEROCYCLIC RADICAL; OR A RADICAL OF THE FORMULA:

-Y-N(-R4)-R5

WHEREIN Y IS

-CO-, -C(=NH)- OR -C(=S)-

AND R4 AND R5 ARE HYDROGEN OR OPTIONALLY SUBSTITUTED ALKYL GROUPS, CYLOALKYL GROUPS, ARALKYL GROUPS OR ARYL GROUPS; WHEREIN THE PERYLENE RADICAL CAN HAVE FURTHER SUBSTITUENTS; WITH THE PROVISO THAT WHEN R2 IS

-X-R3 OR -Y-N(-R4)-R5

THEN R1 IS HYDROGEN.

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.
