Abstract
A method of applying a protective varnish layer on a hydrophilic surface carrying at least one area of hydrophobic ink, and the resultant product. The method comprises: applying to at least the inked portions of the surface a layer of an aqueous dispersion containing 5% to about 60% by weight of a film forming polymer or copolymer and 0.5% to about 10% of an auxiliary film forming material capable of raising the critical surface tension of the hydrophobic inked area; and allowing the applied layer to dry.
