Abstract
In a process for printing a substrate employing apparatus elements such as printing plates, engraved rolls, wiping blades, transfer rolls, metering rolls, or the like, and printing ink which comes into contact with the elements and substrate, the improvement comprising carrying out the printing with an ink comprising an aqueous system of colorant and water dispersible polymer having carbonyloxy linking groups in the linear molecular structure wherein up to 80% of the linking groups may be carbonylamido linking groups, the polymer having an inherent viscosity of at least about 0.1 measured in a 60/40 parts by weight solution of phenol/tetrachloroethane at 25.degree. C. and at a concentration of about 0.25 gram of polymer in 100 ml. of the solvent, allowing the ink to substantially dry, and subsequently contacting the dried ink with a solution of one or more multivalent cation salts to impart thereto a high degree of resistance to water dispersibility.
