    • Disclosed are dye compositions of the formula ##STR1## wherein Cp and Cp' are each coupler compounds of the formula ##STR2## wherein the --COOH group and the --OH group can be in any position on either ring, provided that in the naphthalene ring system there is present least one hydrogen activated through resonance by the --OH group for an electrophilic aromatic substitution coupling reaction, n represents the number of substituents on the rings and is a number of from 0 to 8, and R represents the substituent groups on the ring, wherein each R is independently selected from the group consisting of hydroxyl groups, alkyl groups, substituted alkyl groups, aryl groups, substituted aryl groups, aryl-alkyl groups, substituted aryl-alkyl groups, halogen atoms, and nitro groups. Also disclosed are aqueous ink compositions containing the dyes, processes for making the dyes, processes for making the inks containing the dyes, and printing processes employing the inks.
