Anionic azo compounds which, in the free acid form, have the Formula (1): wherein: Ar and Ar are each independently aryl or substituted aryl providing at least one of Ar and Ar has at least one substituent selected from COOH and COSH; J and J are each independently of formula (2), (3) or (4): each R is independently selected from H, alkyl, substituted alkyl, alkoxy, halogen, CN, ureido and NHCOR; R is H, alkyl, substituted alkyl, aryl, substituted aryl, aralkyl or substituted aralkyl; each T is independently alkyl; each W is independently selected from H, CN, CONRR, pyridinium and COOH; each m is an alkylene chain having 2 to 8 carbon atoms; B is H, alkyl or COOH; R, R, R, R, R and R are each independently H, alkyl or substituted alkyl; L is a divalent organic linking group; n is 0 or 1; each X is independently carbonyl or a group of the Formula (5), (6) or (7): Z is OR, SR or NRR; Y is H, Cl, CN or Z; E is Cl or CN; R, R and R are independently H, alkenyl, substituted alkenyl, alkyl, substituted alkyl, aryl, substituted aryl, aralkyl or substituted aralkyl, or R and R together with the nitrogen atom to which they are attached form a 5 or 6 membered ring; provided (i) if the compound of Formula (1) has no -SO3H groups then it has at least two groups selected from -COOH and -COSH; and (ii) the compound of Formula (1) has at least as many groups selected from -COOH and -COSH as -SO3H groups. The compounds are useful for the preparation of inks for use in ink-jet printing.
