Abstract:
A method of printing onto a substrate using an aqueous ink from an ink jet printer, comprising:obtaining a substrate having a non-hydrophilic surface;coating the non-hydrophilic surface of the substrate with an ink receiving surface mixture which includes a first hydrophilic polymer containing a hydroxyl group, a second hydrophilic polymer selected from the group of hydrophilic polymers having amid, amine, imide and imine groups, and a multicarboxylic acid, or an anhydride derivative thereof, or a carboxyl halide derivative thereof, which polymerizes the second hydrophilic polymer around the first hydrophilic polymer thereby forming a water insoluble colloid;placing the coated substrate into an ink jet printer; andprinting an image on to the coated surface using the ink jet printer by depositing an aqueous ink jet ink onto the coated surface of the substrate.
