    Abstract: Water-insoluble azo colorants, their preparation and use The invention relates to monoazo and disazo compounds of the formula (I) ##STR1## in which D is the radical of a carbocyclic or heterocyclic diazo or bisdiazo component, R.sup.1 and R.sup.2, independently of one another, are each a substituted or unsubstituted aryl or heteroaryl radical, X.sup.1 and X.sup.2, independently of one another, are each ring-forming ether oxygen or a substituted or unsubstituted imide grouping and n has the value 0 or 1, in which rings A and B, independently of one another, can each be additionally substituted and/or carry substituted or unsubstituted fused rings.These new compounds of the formula (I) are obtained by coupling diazotized amines or diamines of the type D--NH.sub.2 or H.sub.2 N--D--NH.sub.2 with (benzoxazol-2-yl)- or (benzimidazol-2-yl)-arylacetamides.Depending on the presence and length of alkyl chains, the compounds of the formula (I) are suitable for use as pigments, disperse dyes or oil-soluble dyes.

    Abstract: Disazo compounds of the formula I ##STR1## in which X and Y are identical or different and denote hydrogen, bromine, chlorine, methyl, methoxy, ethoxy, nitro, trifluoromethyl, carbomethoxy or carboethoxy, A.sup.1 and A.sup.2, independently of each other, represent hydrogen, methyl or ethyl and Z.sup.1 and Z.sup.2 in the 6- or 7-position of the heteroaromatic ring system, independently of each other, represent hydrogen, bromine, chlorine, methyl, methoxy, ethoxy, carbomethoxy, carboethoxy or nitro, are obtained by coupling a monodiazotized p-diaminobenzene substituted by X and Y analogously to the formula I with a 5-acetoacetylaminobenzimidazolone which carries the radicals A.sup.1 and Z.sup.2 analogously to the formula I, and reacting the resulting aminoazo compound after another diazotization with a 5-acetoacetylaminobenzimidazolone which carries the radicals A.sup.2 and Z.sup.2 analogously to the formula I, to give the disazo compound of the formula I. The crude product is subsequently thermally aftertreated at 80.degree. to 200.degree. C.In the case where X, Y or Z.sup.1 does not denote a nitro group, it is possible to use as an alternative to the p-diaminobenzene derivative a corresponding p-aminonitrobenzene derivative. In this case, analogous diazotization and coupling is followed by reduction of the resulting nitroazo compound to the aminoazo compound, which is converted into the compound of the formula I as described above.The symmetrical or asymmetrical disazo compounds of the formula (I) are obtained in a particle size of .ltoreq.0.25 .mu.m and are suitable for use as pigments in printing inks, lakes and emulsion paints, for coloring plastics, rubber, natural and synthetic resins or spinning compositions and for pigment printing on, for example, textile fiber materials and paper. The pigments are tinctorially very strong and have very high solvent, migration, light and weathering fastness properties and a high thermostability.

    Abstract: Symmetrical and asymmetrical disazo compounds of the formula: ##STR1## wherein: the R.sup.1 's are identical or different and are hydrogen, chlorine, bromine, methyl or methoxy;the R.sup.2 's are hydrogen, or, if the R.sup.1 's are hydrogen, the R.sup.2 's are hydrogen, methyl or ethyl, the two R.sup.2 radicals being identical or different; andn is 1 to 4and 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.
