Definitions

  • the invention relates to a binder for coating colors, in particular water-based coating colors, which are used for coating base paper in the production of inkjet paper, coating colors which contain such binders, and inkjet papers produced in this way and a process for their production.
  • Inkjet papers are widely known in different qualities and on the basis of different paper coatings.
  • photo papers which, however, are very expensive and, due to this, are not suitable for "normal” colored prints, as are often required in everyday office life, for cost reasons.
  • Standard papers on the other hand, often produce insufficient depths of ink in inkjet printing, show drying times that are too long and / or lack satisfactory edge sharpness.
  • the object of the invention is to propose a binder for coating colors with which inexpensive inkjet papers can be produced, which show relatively high color densities with inkjet colors and thus replace the higher-quality and expensive qualities of inkjet photo papers in a large number of cases can.
  • a binder of the type described at the outset in that the binder comprises gelatin as a first binder component and proportions of at least one further binder component which is selected from vinyl alcohol polymers, carbohydrates and carbohydrate derivatives, the The solids content of the gelatin in the binder is greater than the sum of the solids contents of the further binder component (s).
  • Gelatin has already been used in a large number of cases for color-receiving layers of photographic papers, but they are complex to produce and therefore correspondingly expensive.
  • gelatin as a binder in ink-receiving layers ensures an excellent depth of color, but the edge definition on matt papers is not always satisfactory.
  • Color absorption layers based on polyvinyl alcohol (PVA) are also known, but these often have only a small depth of color.
  • binders in which gelatin is the main part of the binder according to the invention when mixed with the other binders, show tel components have very good results in terms of color depth and are optimized with regard to edge sharpness.
  • both vinyl alcohol polymers and copolymers as well as carbohydrates and their derivatives can be used to improve the edge definition and the processing behavior of the coating color, without the color depth guaranteed by the gelatin being noticeably impaired.
  • hydroxyalkylated starch derivatives such as e.g. Hydroxypropyl starch derivatives preferred.
  • the solids content of the gelatin is preferably used in the range from 1.1: 1 to 2.5: 1 in relation to the solids content of the further binder components.
  • the proportion of carbohydrate or carbohydrate derivative (s) in the solids content of all Binder components are preferably at least 5% by weight, further preferred is a solids content of the carbohydrates and / or the carbohydrate derivatives in the solids content of all binder components of approximately 8 to 11% by weight .% used.
  • the invention further relates to a coating color for the coating of base paper in the production of inkjet papers, which comprises a binder of the present invention and one or more inorganic pigment (s).
  • the binder / pigment ratio is preferably 1: 1 to 1: 3, in particular 1: 1.3 to 1: 2.5.
  • the coating color can further comprise a cationizing agent to further improve the color fixation.
  • the cationizing agents are preferably selected from cationic polyacrylates, chitosan products and derivatives of chitosan, poly-DADMAC, polyamines, polyamides and polyimines other than gelatin.
  • the cationizing agents are preferably used in the coating slip at 2 to 17% by weight, based on the solids content of the coating slip.
  • the coating color is preferred Agents for stabilizing the inorganic pigment (s) in the binder are added. This stabilizes the pigment suspension in the binder. A proportion of carbohydrate or carbohydrate derivative is already suitable for this. Specific stabilizers for stabilizing the suspension of the pigments in the binder are preferably selected from propylene oxide-ethylene oxide block copolymers and polyvinyl pyrrolidone.
  • the pigments themselves are preferably selected from aluminum silicates, amorphous silica, calcium carbonate, bentonite, zeolites, talc, barium sulfate, calcium sulfate, titanium dioxide, satin white, aluminum hydroxide and kaolin (clay).
  • the invention further relates to an inkjet paper in which the coating color according to the invention is applied on one side or on both sides of the base paper.
  • Order weights per side of up to 15 g / m 2 and more are possible, although for the qualities that target cheaper market segments, order weights of up to 7 g / m 2 , in particular up to 6 g / m 2 , per page of the paper are sufficient.
  • the coating colors of the present invention are aqueous systems with solids contents of approximately 25 to 50% by weight. Deviations downwards and upwards are easily possible.
  • the viscosity is preferably set in the range from 70O to 2500 mPas. Deviations from this range downwards or upwards are not particularly critical.
  • the present invention shows that gelatin is a very suitable binder in the production of inkjet coating colors.
  • gelatin as an organic and fully biodegradable binder, which also meets ecological requirements as a regenerative raw material, provide opportunities for the production of inexpensive inkjet coating colors for the production of improved office papers, which can result in at least medium quality in color printing ,
  • amphoteric character of gelatin plays a special role, whereby the pronounced tendency towards gel formation and the resulting immobilization of the coating color and inkjet printing ink on the paper surface means the use of inexpensive pigments such as e.g. precipitated calcium carbonate or zeolite allowed with good results.
  • inexpensive pigments such as e.g. precipitated calcium carbonate or zeolite allowed with good results.
  • Such very inexpensive pigments have so far not been used successfully in the production of inkjet paper, in particular also in the production of photo papers which can be printed on with inkjet printers.
  • the quality level of the paper can be significantly increased up to qualities that correspond to high-quality conventional inkjet papers.
  • the invention relates to a process for the production of inkjet papers.
  • a simple coating of raw paper (on one or both sides) with the coating color according to the invention an inkjet paper can already be produced which produces a print of at least medium quality.
  • the coating color according to the invention can be applied to the paper using so-called film presses and thus a manufacturing process can be realized in which the base paper can be coated with application weights of up to 7 g / m 2 directly and, if necessary, on both sides if required. This saves an additional work step and an additional drying step compared to the application of coating with a blade, and an additional additional coating and drying step for papers coated on both sides. Treatment of the paper with a size press can also be omitted.
  • the application in the film press is usually carried out at temperatures around 60 ° C, temperatures at which the gelatin has not yet gelled. This additionally simplifies the application of the coating color concept according to the invention based on gelatin.
  • Table 1 The exemplary embodiments 1 to 4 summarized in Table 1 show that with inexpensive coatings of a base paper according to the invention, clearly superior inkjet printing results can be achieved compared to conventional general purpose office papers (photocopy / laser and inkjet printing papers for black and white applications). Table 1
  • a low-bloom gelatin (Gelita® imagel NP) was used as gelatin, modified potato starch ether Emsol K 55 (low viscosity) was used as starch or starch derivative, and Moviol 4-98 was used as PVA binder component.
  • the above-mentioned gelatin is a type B gelatin, low bloom, obtained from bone material.
  • Other low-blooming gelatin types can also be used, while minor adjustments (concentration; viscosity) of the recipes are recommended when using high-blooming gelatin types.
  • the cationizing agents used are either Catiofast CS or Induquat ECR 69L, a cationic polyacrylate.
  • the color densities were determined using a densitometer (Getrag SPM 50).
  • the light stability was tested after accelerated aging in a so-called xenotester (irradiance 1154 W / m 2 ) at 23 ° C. and 50% relative atmospheric humidity for 24 h.
  • the application of the coatings with the film press instead of with a doctor blade has several advantages, which in particular enable a more rational production, in that the coating can be applied to the raw paper directly from the production, if desired on both sides in one work step. This eliminates the need for multiple, time-consuming handling of the paper between separate work steps, and it also saves several drying steps and the use of a size press.
  • the coating weights that can be achieved with a film press are generally sufficient to obtain very high-quality inkjet papers that can be produced very economically.
  • the print quality does not suffer in any way, on the contrary, papers can be obtained which only have the same quality as the high-quality reference paper little inferior. If the amount of coating is increased, further quality increases can be achieved.
