Poly(alkylene oxide) substituted acetoacetanilides of formula (1), wherein B comprises a divalent bridging moiety selected from the group consisting of C1-C6 alkyl, -NHSO2-, -O-, -CO-, -COO-, and -CO NH- ; 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) sub- stituted aceto-acetanilides are prepared by reacting a poly(alkylene oxide) monoamine, diamine or triamine with isatoic an- hydride followed by acetoacetylation of the resultant aminobenzamide. The substituted acetoacetanilides are useful for pre- paring improved diarylide pigment compositions which in turn are useful for preparing storage stable printing inks (espe- cially of the publication gravure type).
