ABSTRACT:
A method of imparting thixotropic properties to printing ink compositions comprising blending at least one ethanolamine compound into a printing ink composition at sufficient concentration to obtain a final printing ink material exhibiting desired thixotropic properties. The ethanolamine compounds usable in connection with the present invention include monoethanolamine, diethanolamine and triethanolamine. In at least one naphthenic ink oil based printing ink composition, desirable thixotropic properties are exhibited when TEA is added at levels varying between 0.5 and 2.0 percent by weight. The optimal amount of TEA in such naphthenic oil based ink composition is approximately 0.7 percent by weight. Ink formulations in accordance with the present invention may be based on organic ink vehicles including naphthenic ink oils and/or hydrocarbon resins. In at least some of the ink compositions of the present invention, the presence of the ethanolamine thixotropic agent also improves the rub resistance of the final ink.
