Aqueous ink binder composition

A method for providing an aqueous ink which has press resolubility and, as a dry film, water resistance comprising

• (a) forming an aqueous ink comprising an aqueous ink binder and, optionally, a pigment, said ink comprising
• (i) a first polymer comprising, as polymerized units, 15-75%, by weight based on the weight of said first polymer, ethylenically unsaturated carboxylic acid monomer having a pKa from 2.0 to 4.6, said first polymer having a calculated Hansch parameter from 1.3 to 2.1, and
• (ii) a second polymer, said second polymer being an aqueous emulsion polymer;
• wherein the weight ratio of said first polymer to said second polymer on a solids basis is from 0.43:1 to 1.5:1;
• (b) applying said ink to a substrate with a press;
• and
• (a) drying, or allowing to dry, said applied ink.
