Abstract: An improved composition for use as a liquid vehicle in ink systems and for printing on diverse substrates. The functional constituents of the compostiion are unsaturated fatty acid esters, difunctional or multifunctional acrylate esters and optionally mixed esters of unsaturated fatty acid and difunctional or multifunctional acrylates and other alpha, beta unsaturated carboxylates. Lithographing ink vehicle formulations of these improved components exhibit exceptional performance. In application, the improved compositions permit a substantial reduction or elimination of solvents and certain drying agents that otherwise form toxic and environmentally sensitive byproducts.

Abstract: The addition of an organophosphato-titanate and an organophosphato-zirconate to printing ink improves the adhesivity of the ink to a variety of substrates. A concentrate of the two organo-metallic components may be added to a conventional ink or added to the ink formulation during the ink's initial preparation. In addition to improving adhesivity, the additives reduce drying time, permit more rapid processing, and minimize the need for solvent diluents.
