    摘要: AN IMPROVED RED PIGMENT IS OBTAINED BY HEATING A COMMERICALLY AVAILABLE PIGMENT OF THE FORMULA:

    3,3''-DI(CL),4,4''-BIS((1-PHENYL,3-(H5C2-OOC-),5-(HO-)

    PYRAZOL-4-YL)-N=N-)BIPHENYL

    IN AN AROMATIC WATER-INSOLUBLE LIQUID BOILING IN A RANGE OF 80* TO 250*C. FOR A PERIOD OF ABOUT 0.75 TO 12 HOURS AND THEN STRIPPING THE LIQUID FROM THE SOLID. THE RESULTANT PIGMENT IS BLUER, BRIGHTER, STRONGER, AND BOTH MORE BLEED RESISTANT AND THERMALLY STABLE THAN THE ORIGINAL PIGMENT STARTING MATERIAL. THE IMPROVED PIGMENT THUS OBTAINED IS USEFUL IN RUBBER, PLASTICS, PRINTING INKS, LACQUERS, PAINT EMULSION AND TEXTILE PRINTING.
