1,4-Di-[2'-(2",4"-dichlorophenylazo)-3'-oxobutyramido]-2-methoxybenzene

Abstract

The compound of the formula ##STR1## exists in an .alpha.-modification and a .beta.-modification, the latter being obtained by treatment of the .alpha.-form with a boiling organic solvent, each of which, but especially the .beta.-modification, is useful as a pigment for the mass pigmentation of synthetic plastics and resins, free from or containing a solvent (e.g., viscose, cellulose acetate, polyethylene, polystyrene, polyvinyl chloride, synthetic leathers and synthetic rubbers), surface coatings (e.g., oil- and water-based paints), lacquers and inks and for pigment printing, textile coating and pigmenting paper in the mass.
