    Abstract: MONOAZO DYESTUFFS FREE FROM SULFONIC ACID GROUPS ARE PREPARED WHICH ARE VALUABLE NEW PIGMENT DYESTUFFS CHARACTERIZED BY GOOD FASTNESS TO LIGHT, SLOVENTS AND MIGRATION, AND BY A GOOD THERMAL STABILITY WHEN USED FOR COLORING PAPERS, LACQUERS, VARNISHES, SYNTHETIC MATERIALS, PIGMENT PASTE AND PRINTING COLORS. THE DYESTUFFS CORRESPOND TO THE GENERAL FORMULA
    WHERE R1 AND R2, INDEPENDENTLY OF ONE ANOTHER, MEANS HYDROGEN, AN OPTIONALLY SUBSTITUTED ALKYL, ARALKYL OR ARYL RADICAL; X STANDS FOR AN OXYGEN OR SULFUR ATOM R FOR NH; K1 IS THE RADICAL OF A MONOFUNCTIONAL COUPLING COMPONENT; R IS A SUBSTITUENT; AND M IS AN INTEGER FROM 0-3.

    Abstract: AZO DYESTUFFS FREE OF SULPHONIC ACID GROUPS AND HAVING THE FORMULA:

    1-(A-N=N-((R-)M-1,4-PHENYLENE)-N(-R1)-CH2-CH(-R2)-),3-R3,

    4-R4,5-R5-PYRAZOLE OR

    1-(A-N=N-((R-)M-1,4-PHENYLENE)-N(-R1)-CH2-CH(-R2)-),2-R6,

    3-R3,4-R4,5-R5-PYRAZOL-2-IUM X(-)

    WHEREIN A IS A DIAZO COMPONENT; R IS A NONIONIC SUBSTITUENT; R1 IS H, ALIPHATIC, ARALIPHATIC, OR AROMATIC; R2 IS H OR METHYL; R3, R4, AND R5 ARE H, ALKYL, ARYL, OR ARALKYL; R4 MAY ALSO BE CARBOALKOXY; R6 IS ALKYL OR BENZYL; AND M IS 0, 1, OR 2. THESE DYESTUFFS ARE USEFUL IN THE DYEING OR PRINTING OF FIBROUS MATERIALS, DYESTUFFS (II) PARTICULARLY FOR THOSE BASED OF POLYMERS OR COPOLYMERS OR ACRYLONITRILE AND DICYANO-ETHYLENE AND DYESTUFFS (I) PARTICULARLY FOR THOSE OF AROMATIC POLYESTERS. PROCESS FOR PREPARING THE ABOVE DYESTUFF BY COMBINING A-NH2 WITH A COUPLING COMPONENT HAVING THE FORMULA:

    1-(((R-)M-PHENYL)-N(-R1)-CH2-CH(-R2)-),3-R3,4-R4,5-R5-

    PYRAZOLE OR

    1-(((R-)M-PHENYL)-N(-R1)-CH2-CH(-R2)-),2-R6,3-R3,4-R4,

    5-R5-PYRAZOL-2-IUM

    WHERE ALL SUBSTITUENT GROUPS HAVE THE ABOVE MEANINGS. PROCESS FOR PREPARING THE QUATERNARY SALT AZO DYESTUFF BY REACTING (I) WITH QUATERNIZING AGENT R6X.
