    • 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.
    • 式中:R 1相同或不同,为氢,氯,溴,甲基或甲氧基; R2是氢,或者如果R1是氢,R2是氢,甲基或乙基,两个R2基团是相同或不同的; 和n为1至4,以及这些化合物的混合物,如着色剂,特别是用于着色高分子量有机材料。 这些化合物显示出高的着色强度,高耐光牢度和非常好的热稳定性,使其非常适用于染色和印刷塑料,天然和合成树脂,橡胶,纸,粘胶纤维素,纤维素,纤维素醚,聚氯乙烯 ,聚酰胺,聚烯烃,卤代聚烯烃,聚苯乙烯,聚氨酯,聚丙烯腈,聚对苯二甲酸乙二醇酯或基于丙烯腈/丁二烯/苯乙烯的共聚物(ABS共聚物),还用于制备印刷油墨,有色漆和乳液漆,并用于印刷图案 并在塑料和金属表面上进行纺织印刷和印刷。
