Abstract: PIGMENTARY COMPOSITIONS COMPRISING AN INTIMATE DISPERSION OF A CRYSTALLINE, LIGHT-STABLE NICKEL CHELATE OF 1NITROSO-2-NAPTHOL AND FROM 0.10 TO 1.0 MOLE, PER MOLE OF THE NICKEL CHELATE, OF CERTAIN ESTER PLASTICIZERS ARE DESCRIBED. THE COMPOSITIONS HAVE IMPROVED TEXTURE AND DISPERSIBILITY AND ARE PRODUCED BY WETTING THE HYDRATED NICKEL CHELATE OF 1-NITROSO-2-NAPHTHOL IN AQUEOUS MEDIUM WITH THE PLASTICIZER, ISOLATING THE WETTED CHELATE AND THEN HEATING THE ISOLATED PRODUCT AT 65-105*C. UNTIL DEHYDRATION IS COMPLETE AND THE CHELATE IS CONVERTED TO ITS CRYSTALLINE, LIGHT-STABLE FORM.
