An aqueous printing ink or its semiaqueous or substantially nonaqueous concentrates exemplified as comprising a substantially homogenous 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-sodio-sulfoisophthalic 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 acetylacetonates 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/l to about 10/l. |
