    Abstract: Symmetrical and asymmetrical disazo compounds of the formula: +TR wherein: the R1's are identical or different and are hydrogen, chlorine, bromine, methyl or methoxy; the R2's are hydrogen, or, if the R1's are hydrogen, the R2's are hydrogen, methyl or ethyl, the two R2 radicals being identical or different; and n is 1 to 4 and mixtures of such compounds as colorants, especially for pigmenting high molecular weight organic material. These compounds display high tinctorial strength, high fastness to light, and very good stability to heat, making them outstandingly suitable for dyeing and printing plastics, natural and synthetic resins, rubber, paper, viscose, cellulose, cellulose esters, cellulose ethers, polyvinyl chloride, polyamides, polyolefins, halogenated polyolefins, polystyrene, polyurethanes, polyacrylonitriles, polyglycol terephthalates or copolymers based on acrylonitrile/butadiene/styrene (ABS copolymers) and also for the preparation of printing inks, colored lacquers and emulsion paints and for pigmenting printing pastes for graphical and textile printing and printing on plastic and metal surfaces.
