Abstract:
Disclosed is a substantially water-free pre-treatment composition having at least one of an acid or an acid anhydride in an organic matrix. Also disclosed is a kit of parts having the pre-treatment composition and an ink composition that has an intrinsic inferior water fastness when printed, where the ink contains a compound that is soluble in alkaline environment (ink as such) and insoluble in a neutral and/or acidic environment. Also disclosed is a printing method for improving the water fastness of a print made with an ink that has intrinsically low water fastness, by using a pre-treatment composition as disclosed.

Claim (Index 7):
A method of printing, comprising the steps of:\n a) providing a substantially water free pre-treatment composition, comprising an organic matrix comprising at least one organic solvent that is miscible with water and at least one selected from an acid or an acid anhydride that is soluble in the organic matrix; b) providing an aqueous ink composition, comprising an alkali soluble latex resin and/or a latex resin having an acid number of between 15 mg KOH/g and 130 mg KOH/g, the aqueous ink composition having a pH of above 7; c) providing a print medium; d) applying the pre-treatment composition onto the print medium to obtain a pre-treated print medium; and e) printing an image with the aqueous ink composition onto the pre-treated print medium.
