Abstract
An aqueous composition suitable for use as a printing ink is provided which comprises an aqueous solution or emulsion of a film-forming polymer containing a titanium compound which is the reaction product of a titanium orthoester, a beta-diketone and a dihydric alcohol. Preferably the composition also contains a pigment or dye and other conventional printing ink additives. The titanium compounds enhance the adhesion and heat resistance properties of the compositions and in contrast to known additives do not lose their efficacy when the ink is stored for more than a few hours.
