Abstract: Water-fast printing of paper stock using a colorant solution containing water-soluble polymeric dyes is accomplished by a three step process. Step 1 is selecting a paper stock characterized as containing at least 250 ppm by weight of cation, particularly a polyvalent metal cation (especially Ca.sup.2+ or Al.sup.3+). In step 2, a colorant solution is applied to the paper. This solution is water-based, containing up to 30 wt % of an organic paper-penetrating agent (such as an alkanol), and at least 500 ppm of one or more anionic group-possessing polymeric colorants. In step 3, the solvent is exhausted by either evaporation (which may be aided by the application of heat) or diffusion into the paper stock, or by a combination of both.
