Abstract
The present invention relates to fast drying waterborne printing inks and to method of using such inks in high speed printing processes, such rotogravure and flexographic printing processes. The printing ink includes, for example, a blend of a latex binder and a polyfunctional amine. The pH of the ink is raised by adding a sufficient amount of base, to a point where essentially all of the polyfunctional amine in the blend is in a deprotonated state.
