摘要： Disclosed are red shade yellow compositions characterized by the formula: ##STR1## wherein X is a lower alkyl or a --COOR.sub.1 group; wherein R.sub.1 is a hydrogen or lower alkyl group; each Y is independently a lower alkyl, lower alkyloxy or halogen group; a is 0, 1, or 2; and M is a divalent metal. Also disclosed is a process for preparing red shade yellow pigment compositions prepared by initially a diazonium component comprised of one or more aromatic amines wherein at least one of said amines is a 1-sulfo-2-naphthylamine; and thereafter coupling the diazonium component with a coupling component comprised of a pyrazolone coupler to form a dye, and metallizing said dye with at least one divalent metal.
