Forming an aqueous printing ink or its semiaqueous or substantially nonaqueous concentrates exemplified as comprising a substantially homogeneous system of the components: (1) from about 4 to about 90 weight % of one or more polyester materials having an acid component of from about 75 to about 84 mole % isophthalic acid and conversely from about 25 to about 16 mole % 5-sodiosulfoisophthalic acid, and having a glycol component of from about 45 to about 60 mole % diethylene glycol and conversely from about 55 to about 40 mole % 1,4-cyclohexanedimethanol or ethylene glycol or mixtures thereof; (2) from none to about 70 weight % of pigment material; (3) from about 0.01 to about 90 weight % of water; and (4) one or more acetylacetontes of the formula M[CH-(COCH3)2]n wherein M is Al, Zr, Ni, Ca, V, or Fe, and n is the chemical valence of M, the weight ratio of polyester to total acetylacetonates being from about 10,000/1 to about 10/1.
