Abstract

NEW MATERIAL:A yellow pigment bis-( 4,5,6,7-tetrachloroisoindolin-1-on-3-ylidene )-phenylenediamine(1,4) having strong diffraction peaks at angles (2θ) of diffraction of about 9.8, 24.5, 25.2, and 29.7°, of the formula.
USE: Coating automobiles and outdoor structures, and coloring resins.
PROCESS: A pigment of the formula is dispersed in an aromatic solvent, and a solution of potassium hydroxide in a lower alcohol is added to the dispersion to form a potassium salt. The salt crystals thus formed are isolated, dried, dispersed in water, and warmed, or hydrolyzed with an acid to free the pigment, which is heat-treated.
