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.

Abstract: A new method for the production of titanium derivatives of carboxylic acids is provided. A liquid or solid carboxylic acid is suspended in an inert liquid diluent in which it is substantially insoluble and reacted with a titanium alkoxide to form a titanium derivative which is also substantially insoluble in the inert diluent.The invention provides a simple method for the production of titanium compounds which are easily transported and can readily be dissolved in water for use, for example, as catalysts and cross-linking agents.
