  • Patent number: 4269769
    Abstract: 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.
