Abstract: WATER-SOLUBLE QUATERNIZED CATIONIC MONOAZO DYESTUFFS OF THE FORMULA

1-R1,3-(B-N=N-),4-R5,6-R2-1H-1,2,4-TRIAZOLIUM Z(-)

WHEREIN B IS A RESIDUE OF A COUPLING COMPONENET AND R1, R2, R5 AND Z$ ARE THE RADICALS INDIVIDUALLY DEFINED IN THE SPECIFICATION AND CLAIMS. THE CATIONIC MONOAZO DYESTUFFS ARE SUITABLE FOR THE DYEING OF VARIOUS MATERIALS SUCH AS PAPER, MORDANT-TREATED CELLULOSE FIBERS, ACETATE FIBERS, SILK, LEATHER, POLYESTER FIBERS AND THE LIKE AND ESPECIALLY FOR THE DYEING OF FIBROUS MATERIALS MADE OF POLYACRYLONITRILE OR COPOLMYERS THEROF. THE DYEINGS IN ORANGE TO REDDISH VIOLET SHADES OBTAINED WITH THE NEW DYESTUFF POSSESS AN EXCELLANT FASTNESS TO LIGHT, WASHING AND THE LIKE. THE DYESTUFF IS FURTHER CHARACTERIZED BY THE FACT THAT THE RESULTING DYEING CAN BE MORE COMPLETELY DISCHARGED BY TREATGMENT WITH STANNOUS CHLORIDE THAN THE DYEINGS OBTAINED BY ANALOGOUS DYESTUFFS HITHERTO KNOWN.

Abstract: NEW WATER-SOLUBLE QUATERNIZED CATIONIC MONOAZO DYESTUFFS REPRESENTED BY THE GENERAL FORMUA

2-R1,3-R2,4-R6,5-((1-R4,2-R3,R5-INDOL-3-YL)-2H-1,2,4-

TRIAZOLIUM Z(-)

WHEREIN R1, R2, R3, R5, R6 AND Z$ HAVE THE MEANINGS RESPECTIVELY DEFINED IN THE DESCRIPTION AND CLAIMS. THE NEW CATIONIC MONOAZO DYESTUFFS ARE SUITABLE FOR DYEING VARIOUS FIBROUS MATERIALS SUCH AS MORDANT-TREATED CELLULOSE FIBRES, ACETATE FIBRES, PAPER, SILK, LEATHER, SYNTHETIC FIBRES, ESPECIALLY FIBRES OF POLYACRYLONITRILE, POLYESTERS AND INTERPOLYMERS THEREOF AND THE LIKE. GREENISH YELLOW TO REDDISH YELLOW SHADES OF THE DYEING THUS OBTAINED ARE CHARACTERIZED BY THEIR EXCELLENT FASTNESS TO SUNLIGHT, WASHING, RUBBING AND HEAT AND THEIR ALMOST COMPLETE LACK OF PHOTOTROPISM.

Abstract: A BASIC DYESTUFF OF THE FORMULA:

((2-R2,3-Q,4-R3-IMIDAZOL-1-YL)-P-N(-R1)-B-N=N-)N-A (X)N(-)

WHEREIN: A IS A RESIDUE SELECTED FROM THE GROUP CONSISTING OF SUBSTITUTED AND UNSUBSTITUTED BENZENES, DIPHENYLS, DIPHENYLMETHANES, AZOBENZENES, THIAZOLES, BENZOTHIAZOLES, THIADIOZOLES, TRIAZOLES, AND DERIVATIVES THEREOF, WHEREIN THE SUBSTITUENTS ARE NON-WATER-SOLUBILIZING SUBSTITUENTS SELECTED FROM THE GROUP CONSISTING OF CHLORINE, BROMINE, NITRILE, NITRO, ACETYL, TRIFLUOROMETHYL, LOWER ALKYLSULPHONYL, SULPHONAMIDE, MONO- AND DI-LOWER ALKYLSULPHONAMIDE, LOWER ALKOXYCARBONYL, ACETYLAMINE, PHENYLAMINE, PHENYL, LOWER ALKYL AND LOWER ALKOXY; B IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF SUBSTITUTED AND UNSUBSTITUTED PHENYLENE AND NAPHTHYLENE RADICALS BONDED TO THE AZO AND THE AMINO GROUPS IN THE 1- AND 4-POSITIONS, WHEREIN THE SUBSTITUENTS ARE NON-WATERSOLUBILIZING SUBSTITUENTS SELECTED FROM THE GROUP CONSISTING OF CHLORINE, METHYL, METHOXY AND ACETYLAMINO; R1 IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF LOWER ALKYL HAVING FROM 1 TO 4 CARBON ATOMS, B-CYANOETHYL, B-HYDROXYETHYL AND BENZYL; R2 AND R3 EACH IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, METHYL, ETHYL AND PHENYL; P IS AN ALKYLENE RADICAL HAVING FROM 2 TO 3 CARBON ATOMS; Q IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF LOWER ALKYL, BENZYL AND CARBAMOYLETHYL; X IS AN ANION; AND N IS 1 OR 2. THE DYESTUFFS OF THE PRESENT INVENTION ARE USEFUL AS DYES FOR A WIDE VARIETY OF MATERIALS, INCLUDING TANNED CELLULOSIC FIBERS, SILK, LEATHER, CELLULOSE ACETATE, PAPER, AND SYNTHETIC FIBERS, ESPECIALLY POLYMERIC AND COPOLYMERIC ACRYLONITRILE. THE DYESTUFF OF THE PRESENT INVENTION IS PARTICULARLY SUITABLE FOR DYEING POLYACRYLONITRILE FIBERS WITH EXCELLENT LIGHT, WET, AND HEAT-FASTNESS PROPERTIES.
