Definitions

  • the invention relates to a method for making printing paper as defined in the preamble of claim 1 and to a mixture composition for the surface-sizing of printing paper as defined in the preamble of claim 4.
  • the inkjet-based printing techniques it is important to ensure sufficient printing ink absorption in the high speed inkjet papers to provide a sufficiently good colour print.
  • the important criterion is that the printing inks of different colours do not blend together.
  • uncoated papers sufficient absorption can be ensured by low hydrophobic sizing level of the base paper, which has been disclosed e.g. in patent application WO 2006067273 .
  • anionic aqueous printing ink must be bound to the paper in order for the print to be waterfast. Waterfastness is essential for example in bank balance statements and other similar prints. It is known that waterfastness can be improved by adding cationic polymers to the surface-size or coating on the surface of the paper.
  • the most commonly used polymer is polyDADMAC.
  • Many of the fixatives used at the wet end of the paper machine are suitable for this purpose.
  • Patent application WO 2006067273 discloses the surface treatment of printing paper with a cationic polymer together with an internal sizing treatment of the paper. The suggested optimal amount is 2g/m 2 , in which case about half of the amount of the surface-size should be replaced with the cationic polymer.
  • the amount of the cationic polymer as presented above increases the production costs of the printing paper.
  • EP 0327215 From WO 98/32920 , EP 0327215 , US 5672392 and EP 0747235 are known different sizing or coating compositions and methods for surface sizing or coating of substrate. From US 6764726 is known an ink jet recording sheet having improved image waterfastness.
  • the objective of the invention is to eliminate the drawbacks referred to above.
  • One specific objective of the invention is to disclose a new method and surface-size mixture composition for making printing paper.
  • the objective of the invention is to disclose a new way of improving printability of printing paper.
  • the invention is based on a method for making printing paper, which method comprises forming an uncoated paper.
  • a surface-size mixture comprising starch and polyvinyl pyrrolidone and cross-linker is arranged on the surface of the uncoated paper for improving printability of the paper, and the surface-size mixture comprises 45 - 99% starch, 1 - 50% polyvinyl pyrrolidone and less than 5 % cross-linker which is epoxy-based or glycosal-based cross-linker, and the starch is cationic starch.
  • Printability means print quality, waterfastness and/or degree and rate of absorption.
  • Print quality means print sharpness and/or evenness.
  • the invention is specifically based on improving inkjet printability in uncoated papers by a new surface-size composition.
  • paper means any fibre-based paper, board or fibre product or the like.
  • the paper may have been made from chemical pulp, mechanical pulp, chemimechanical pulp and/or the like.
  • the paper may be in the form of a wet web, dried web or sheet, or in other form which is suitable for the purpose.
  • the paper may comprise suitable fillers and additives.
  • uncoated fine paper which mainly does not comprise mechanical pulp, e.g. WFU or UWF, is used in the method.
  • uncoated paper which does comprise mechanical pulp, e.g. SC paper or newsprint.
  • One embodiment of the invention comprises producing high speed inkjet paper with good printability.
  • the surface-size mixture is in the form of a solution, dispersion or paste.
  • the mixture can be arranged or applied on the surface of the paper by any manner known per se in the art.
  • the surface-size mixture is arranged on the surface of the formed paper web in conjunction with the web formation, e.g. in conjunction with the drying. In one embodiment, the mixture is arranged on the surface of the formed web in a separate step after the formation of the web.
  • a base paper web is formed in a manner known per se and cut to the correct width.
  • the web is coated with the surface-size mixture. If desired, the web is cut into sheets or the like, and the web or the paper products cut off from it are provided with the desired print in the desired manner.
  • the print can be provided by a digital printing method, e.g. inkjet-based technique.
  • the invention is based on a mixture composition to be used for making printing paper.
  • the mixture composition comprises starch and polyvinyl pyrrolidone and cross-linker and the mixture composition comprises 45 - 99% starch, 1 - 50% polyvinyl pyrrolidone and less than 5 % cross-linker which is epoxy-based or glycosal-based cross-linker, and the starch is cationic starch, and the mixture composition can be arranged on the surface of an uncoated paper as surface-size.
  • the mixture composition comprises less than 5% cross-linker.
  • the cross-linker may be e.g. an epoxy-based, a glycosal-based or a zirconium-based cross-linker.
  • the mixture composition comprises a cationic polymer. In one embodiment, the mixture composition comprises less than 15% cationic polymer.
