Poly (alkylene oxide) substituted acetoacetanilides of the formula: <IMAGE> wherein B comprises a divalent bridging moiety selected from the group consisting of C1-C6 alkylene, -NHSO2-, -O-, -CO-, -COO-, and -NCHO-; X comprises a poly (alkylene oxide) having a number average molecular weight of about 200 to 10,000; R comprises 0 to 4 moieties independently selected from the group consisting of C1-C4 alkyl, C1-C4 alkoxy and halogen; and d is an integer of 1 to 3. The poly (alkylene oxide) substituted acetoacetanilides are prepared by reacting a poly (alkylene oxide) monoamine, diamine or triamine with isatoic anhydride followed by acetoacetylation of the resultant aminobenzamide. The substituted acetoacetanilides are useful for preparing improved diarylide pigment compositions which in turn are useful for preparing storage stable printing inks (especially of the publication gravure type).
