Abstract
NEW MATERIAL:A pigment of bis-(4,5,6,7-tetrachloroisoindolin-1-one-3-ylidene)- phenylenediamine shown by the formula showing a X-ray diffraction pattern having a strong diffraction at an angle of diffraction (2θ=Cu-Kα) of 25.3 degree, middle diffraction intensity at the angles of diffractions of 9.6 and 12.4 degrees, and relatively weak diffraction intensity at 27.3, 28.1, 32.2, 34.2, 39.3, 43.8, and 47.6 degrees.
USE: A yellow pigment having slightly blue shade, extremely bright color, and improved weather resistance and heat resistance.
PROCESS: N,N'-p-Phenylene-bis-(1-oxo-3-imino-4,5,6,7-tetrachloroisoindolin) is reacted with a metal alcoholate in an alcohol or in an aromatic organic solvent to give a yellow crystal, which is isolated in water, dispersed into water, and heated in the presence of the aromatic solvent. The prepared yellow crystal is washed with water and dried.
