Abstract

A paper coating for ink-jet printing according the invention, comprising of sodium aluminosilicate, sodium chloride, ammonium chloride, polyvinyl alcohol, aliphatic polyamine and polyaluminum chloride, of hydrophilic properties characterises in that weight ratio of sodium chloride, ammonium chloride and polyaluminum chloride to aliphatic polyamine is 8.55:1. The coating is applied by a machine on a paper ground on one- or two-sides.

Description

  • The present invention relates to a paper coating for ink-jet printing.
  • Ink-jet printing, a technique pioneered during the second half of twentieth century, has created a need for paper of appropriate quality. During the last years of last century, special coatings designed for ink acceptance during printing were applied to improve print quality. The aim was achieved by hydrophilic coatings applied onto paper ground, using silica gel, polyvinyl alcohol and/or carboxymethylcellulose plus low molecular weight cationic polymer (e.g. modified polyethylenimine, polyvinylamine, condensation product of organic amides with formaldehyde, polyacrylamide) [Handbook of Paper and Board. Ed. H. Holik, WILEY-VCH Verlag GmbH & Co. KgaA, 2006, Weinheim, pp. 98-99]. Patent and specialist literature provide numerous versions of ink-jet paper coatings.
  • A paper ground for ink-jet printing with a cationic two-component surface coating is known from patent description US4,554,181 . Cationic polymers applied in that invention characterises in that the cationic groups are available for anionic component of ink dye(s). The other source of cations are salts of a metal from group II, III or the Transition Metals of the Periodic Table of Elements of solubility greater than 5 g in 100 ml of water at 23°C. Due to tend to colour the paper, salts of Fe2+, Fe3+ and Cu2+ are scarcely useful. It was revealed that salts of strong acids (including hydrochloric acid) are capable of insolubilising anionic ink components, but the anionic parts of the strong acids accelerate paper degradation.
  • A coating for ink-jet paper is known for Japanese patent application description JP 2001315433 , which consists of 2-10 parts by weight of inorganic electrolyte (preferably sodium chloride), 0-100 parts by weight of porous absorbing material (e.g. silica particles), and up to 100 parts by weight hydrophilic or vinyl acetal resin. The mixture is to be prepared onto a polyethylene foil and then transferred onto a paper.
  • The Polish patent application P405943 discloses a paper coating for ink-jet printing according the invention, comprising of sodium aluminosilicate, sodium chloride, polyvinyl alcohol, aliphatic polyamine and polyaluminum chloride, of hydrophilic properties, which characterises in that weight ratio of sodium chloride and polyaluminum chloride to aliphatic polyamine is 9.6 : 1.
  • A paper coating for ink-jet printing according the invention, comprising of sodium aluminosilicate, sodium chloride, ammonium chloride, polyvinyl alcohol, aliphatic polyamine and polyaluminum chloride, of hydrophilic properties characterises in that weight ratio of sodium chloride, ammonium chloride and polyaluminum chloride to aliphatic polyamine is 8.55 : 1. The coating is applied by a machine on a paper ground on one- or two-sides.
  • Unexpectedly, decrease of sodium chloride content, simultaneously preserving very high concentration of chlorides in the mixture (supplied with ammonium chloride) provides very good printing quality, better than one according to the solution disclosed in P405943. In addition, it is suitable for direct, mechanical applying on a paper with a standard machines. In laboratory tests on papers for ink-jet printing the following parameters were recorded: mottling, show-through, bleeding and optical density. Paper with the coating according to the invention was produced on a size press of a papermaking machine. Assessment of coatings was done by OCE Printing Systems in 2014 showed high quality. In the following charts AmberHighway 80 gsm 2014-02 Trial and AmberHighway 90gsm 2014-02 Trial are the tested paper with coating according to this invention.
    Figure imgb0001
    Figure imgb0002
    Figure imgb0003
  • The referred laboratory described papers with coating according to this invention as:
    • drying is assessed as correct,
    • both versions of the paper are qualified as adequate for on-line printing as sufficiently quick drying.
    • colour gamut is better in comparison with paper coating known from application P405943.
  • The results confirm a printing quality comparable with those of the reference paper for ink-jet printing. No accelerated degradation was found.
  • The invention is illustrated by the following exemplary embodiment.
  • Example. Water is to be poured into a mixer with a high-speed stirrer at amounts depending on demanded concentration of the coating mixture, and than the ingredients are added gradually at the indicated amounts::
    Ingredient Commercial name Amount of a dry substance in g/100 g of the mixture Weight percentage of all ingredients
    Sodium aluminosilicate Zeocros PF 2.00 17.45%
    Sodium chloride evaporated salt 2.50 21.93%
    Ammonium chloride 3.00 26.32%
    Polyvinyl alcohol PVOH BP-05 3.00 26.32%
    Aliphatic polyamine CATIOFAST 160 0.67 5.88%
    Polyaluminum chloride PAX 18 0.23 2.02%
  • Every ingredient shall be added as soon as a previous is completely dissolved in the mixture. A paper sheet is to be covered with the mixture with a papermaking machine or with a covering machine on one or two sides. Paper density of the produced paper is 70 - 160 g/m2, and coating density is 2-4 g/m2.
