Coating for treating substrates for ink jet printing, method for treating said substrates,
and articles produced therefrom |
(57) A method of producing a printed substrate so as to improve the adhesion, colorfastness
and washfastness of either reactive or acid dye-based inks printed onto the substrate,
the method includes the steps of providing a substrate, treating the substrate with
an aqueous coating formulation comprising a cationic polymer or copolymer, a fabric
softener, treating the substrate of step with an imbibing aqueous solution of either
urea, and an ingredient selected from sodium bicarbonate, sodium carbonate or combinations
thereof, or ammonium sulfate, drying the substrate, printing on the substrate with
either an acid or reactive dye-based ink, depending on the coating and post treating
the printed substrate.
