Abstract: A process for improving the printability of paper and paper products by enhancing the water resistance of ink-jet printed images, wherein the process comprises treating the paper or paper products with aqueous solutions of cationic polymers comprising vinylamine units and having a charge density of at least 3 meq/g as the sole treatment composition in aqueous solution, wherein the sole treatment composition is applied in an amount from 0.05 to 5 g/m2 to the surface of the paper or the surface of the paper product.

Abstract: Paper and cardboard are produced by draining pulps, with sheet formation and drying of the sheets, by a process in which first (a) polyethyleneimines having a molar mass M w of more than 500,000 or polymers containing vinylamine units and having a molar mass of from 5000 to 3 million and then (b) cationic polyacrylamides or polymers containing vinylamine units, the molar masses M w of the polymers each being at least 4 million, are added to the pulps, and the pulp is then subjected to at least one shearing stage and is flocculated by adding bentonite, colloidal silica or clay.

Abstract: The addition of a (co)polymer B, comprising an N-vinylcarboxamide, to a polymer dispersion, the bonding force of this binder in a paper coating composition is increased, and the optical brightener in the paper coating composition is extremely strongly activated. Polymer dispersions containing: (i) a (co) polymer A with at least one main monomer selected from 1-20C alkyl (meth)acrylate, vinyl ester from up to 20C carboxylic acid, up to 20C vinyl aromatics, ethylenically unsaturated nitrile, vinyl halide, vinyl ether or 1-10C allyl ethers containing alcohols and aliphatic 2-8C hydrocarbons and 1 or two double bonds included by polymerization (sic); and (ii) at least one N-vinylcarboxyic acid amide in polymerized form containing (co)polymer B. Independent claims are included for: (1) a paper coating composition containing the polymer dispersion; and (2) a process for preparation of the polymer dispersion by mixing a dispersion of (co)polymer A with (co)polymer B, its dispersion, solution, suspension, or emulsion, and a brightener, its solution, or suspension.

Abstract: Paper, board and cardboard are produced from paper stocks which contain tacky impurities by the addition of surfactants and cationic polymers having a charge density of at least 1.5 meq/g (measured at pH 7) and a molar mass Mw of the cationic polymers of at least 15,000 and drainage of the paper stocks with fixation of the tacky impurities in the paper produced.
