摘要： Pigments of the formula ##STR1## wherein X.sub.1 and X.sub.2 may be the same or different from one another and each is hydrogen, chlorine, fluorine, bromine, lower alkyl having 1 to 3 carbon atoms or alkoxy having 1 to 3 carbon atoms; and wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of pyrazolonyl and substituted pyrazolonyl are obtained by coupling a pyrazolone with a 4,4'-diaminobenzanilide. The pigments are useful in rotogravure inks.

摘要： Yellow pigments having a greenish hue are represented by the formula: ##STR1## wherein X.sub.1 and X.sub.2 may be the same or different from one another and each is hydrogen, halogen (chlorine, fluorine or bromine), lower alkyl or alkoxy having from 1 to 3 carbon atoms; and wherein R.sub.1 and R.sub.2 may be the same or different from one another and each is the residue from an acyl-acetyl-amino-aromatic coupling agent or the residue from a pyrazolone coupling agent. Pigments are obtained by coupling of (1) an aceto-acetyl-amino-aromatic compound or (2) of a pyrazoline, with a 4,4'-diamino-benzanilide. The yellow pigments have the characteristic of having a high tintorial yield, a high degree of purity of tone (brightness), a good fastness to light, and good resistance to organic solvents. These pigments are particularly useful in the polychrome graphic industry.

摘要翻译： 具有绿色色调的黄色颜料由下式表示：其中X 1和X 2可以彼此相同或不同，各自为氢，卤素（氯，氟或溴），低级烷基或烷氧基，具有1至 3个碳原子; 并且其中R 1和R 2可以彼此相同或不同，并且各自为酰基 - 乙酰基 - 氨基 - 芳族偶联剂的残基或来自吡唑啉酮偶联剂的残基。 通过（1）乙酰乙酰氨基 - 芳族化合物或吡唑啉的（2）与4,4'-二氨基 - 苯甲酰苯胺的偶合获得颜料。 黄色颜料的特征是具有较高的色泽产率，高纯度的色调（亮度），良好的耐光牢度和良好的耐有机溶剂性。 这些颜料在多色图形工业中特别有用。
