Definitions

  • the present invention relates to printable and printed substrates, in particular special papers, processes for their production, and their uses.
  • WO 97/18090 (Kimberly-Clark) describes a printable special paper which has a filmable layer arranged on a carrier material and which is intended to be filmed over a large area after printing using heat and / or pressure. The print is then essentially irreversibly bound and protected behind the film.
  • a special paper based on the essentially same idea is also described in DE 196 28 342 (Sihl GmbH, Düren) and EP 0 826 823 by the applicant.
  • the carrier material and the formulation of the filmable layer are chosen in the first font so that the filmed paper is particularly resistant to the influence of water.
  • the specialty papers described above have a number of disadvantages.
  • the special papers have to be kept at temperatures of 140 ° C to 180 ° C for a period of 20-60s for complete filming. Such conditions can only be set with very special heating presses or with laminators of the highest price range.
  • the special papers are no longer planar after the filming, or a curvature of the papers occurs during filming in the laminator and the papers therefore occasionally die Have a tendency to get stuck in the laminator.
  • the object of the invention is to specify how prints, in particular inkjet prints, more abrasion-resistant, smudge-proof, water-resistant, brilliant, light-resistant and finally also more resistant can be made in the sense of increased security against forgery.
  • the substrate should also be inexpensive to manufacture and using conventional machines.
  • the subject of the invention is a printable substrate according to claim 1 and a method for producing such a substrate according to claim 7.
  • the invention further relates to a printed substrate according to claim 10 and a method for producing such a substrate according to claim 12.
  • Claims 17-19 relate to special uses of the substrates according to the invention.
  • the essence of the present invention is therefore to apply e.g. first apply a pressure-fixing layer from paper on at least one side, and apply a filmable coating containing organic pigments (plastic pigments) and binders to this pressure-fixing layer.
  • This filmable coating is intended to be filmed after printing by supplying at least heat, but preferably heat and pressure.
  • the ink penetrates into the porous filmable coating during printing, penetrates it and is bound on or in the fixing layer when the pressure fixing layer arranged between the carrier material and the filmable layer is reached. In other words, before filming, part of the ink is in the filmable layer, and the other, usually larger part of the ink is in resp. bound on the pressure fixing layer.
  • Other printing inks such as those used in offset processes, and which cannot penetrate into the filmable coating due to their physicochemical properties, remain essentially on the surface of the filmable coating after the printing process.
  • Filming the filmable layer means that the print subsequently behind or in the filmed layer is more abrasion-resistant, smudge-proof, water-resistant, brilliant and light-resistant.
  • the use of the pressure-fixing layer means that if there is residual porosity after filming or microscopic cracks in the filmed layer, the print is still water-resistant because the pressure-fixing layer binds the ink under the film.
  • the applied printed image appears to the viewer with increased brilliance. It has also been shown that print images produced according to the invention are substantially more lightfast than conventional inkjet prints. Additional and expensive laminations, such as are sometimes made with inkjet papers, are superfluous. Other printing inks remaining essentially on the surface after the printing process are also partially welded in by the filming and are more strongly bound.
  • a first preferred embodiment is characterized in that the filmable coating contains the following components:
  • binder 1-30% by weight, particularly preferably 2-10% by weight, of binder
  • UV stabilizers - 0- 5% by weight

  • Such a formulation of the filmable layer allows filming temperatures below or in the range of 100 ° C. These are conditions that can be easily set with cheap laminators. However, despite the low film-forming temperature, the formulation still allows a coating process for the substrate in which there is no premature filming of the coating when the application of the filmable layer dries, and moreover the substrate does not have to be stored under special conditions such as under cooling before printing. Furthermore, the low filming temperature also has the advantage that the carrier material does not dry out to the same degree during filming as is the case at temperatures above 100 ° C. In this way, the substrates remain flat after filming and the risk of jams in the laminator is reduced. It is shown that, in particular when using the above, deep-melting organic pigments, the use of the pressure fixing layer results in a precise and waterproof printed image.
  • the pressure-fixing layer is cationic and the ink is absorbent, particularly preferably water-resistant.
  • the ink is actively removed from the layer sucked down and, since inks are usually anionic in character, precipitated and fixed by the cationic portions of the pressure-fixing layer.

Catiofast * PR 8106 (BASF, Ludwigshafen, DE) is actually an AOX-free wet strength agent for the production of wet-strength paper qualities in the neutral range. It is a light to dark yellow aqueous, 22% solution of a polymer based on vinylamine and N-vinyl-formamide and acts as a cationic, water-soluble, high-molecular resin for fixing anionic inks.

  • the following composition of the filmable layer 10 formulated for application as an aqueous dispersion has proven to be suitable, for example:
  • Baystal Polymer Latex GmbH & Co KG, Dormagen, DE is a 50% colloidal dispersion made from a copolymer of butadiene, styrene and acrylic acid and a low proportion of emulsifier. The styrene content is approximately 78%. Baystal forms the major part of filmable organic polymer with a glass transition temperature in the range of 50 ° C-60 ° C. These are pigment beads, such as those formed in emulsion polymerization, with a size in the range of 0.5 - 1 ⁇ m.
  • Gohsenol (Nippon Gohsei, Osaka, JP) and Mowiol (Clariant, Muttenz, CH) are aqueous solutions of polyvinyl alcohol, serve as binders and have a water-absorbing effect.
  • particularly long-chain polyvinyl alcohols can advantageously be used.
  • Litex (Polymer Latex GmbH & Co KG, Dormagen, DE) is an aqueous anionic 50% dispersion of a carboxylated styrene-butadiene copolymer (copolymer of butadiene, styrene and acrylic acid), which is used as a binder for coating colors in the paper industry.
  • Litex has a glass transition temperature of approx. -6 ° C and serves here as a film-forming aid and to increase the gloss.
  • Plextol (Polymer Latex GmbH & Co KG, Dormagen, DE) also serves with a glass transition temperature in the range of -47 ° C.
  • Plextol is a 60% dispersion of a self-adhesive acrylic polymer.
  • Tinuvin (Ciba SC, Basel, CH) is an optional UV stabilizer. It supports, among other things, the light fastness of the colors fixed in the underlying pressure fixing layer 11.

  • the ink penetrates into or through the porous filmable layer 10 and is sucked in by the pressure-fixing layer 11 and fixed locally on it due to the cationic character of the layer 11.

  • pressure is preferably used at the same time for filming in addition to heat.
  • a pressure in the range between 0.5-5 bar in a static press or a corresponding line pressure in a continuous laminator has proven to be sufficient and cheap.

  • Films with a roughness between 0.01 - 5 ⁇ m are suitable for "matt" surfaces and those with a roughness less than 0.01 ⁇ m for "glossy” surfaces. After filming, the film must of course be easily removable from the filmed surface. Polyester or polyamide films (such as GRILON 6, 10, 12) are therefore suitable. Siliconized papers are also possible covers for the lamination process, and it turns out that especially not too thick papers with thick siliconization contribute to a good and even filming. For example, it is advantageous to design a so-called carrier in which the substrate to be filmed can be inserted and the inner surface of which has the desired surface structure. The substrate is placed in the carrier for the lamination process, and after the lamination, the carrier is removed again from the filmed paper. Such a carrier can ideally be used several times.

  • the offset printing ink remains essentially on the surface, but is also partially welded in during filming and fixed. It is also conceivable to combine the substrate with the use of conventional film pockets, in which the paper is embedded and laminated, for outdoor applications or similar applications in which extremely pronounced protection of the printed image is necessary.

Abstract

Selon l'invention, on obtient, pour un substrat en particulier à base de papier, une qualité d'impression élevée, une bonne protection de l'impression contre l'eau et l'effacement par frottement, par le fait qu'une couche support (12) présente, au moins sur un côté, une couche de fixation d'impression (11), et que, sur cette couche de fixation d'impression (11), est placé un revêtement (10) pouvant être transformé en film, contenant des pigments organiques filmogènes et un liant. Cette structure permet l'utilisation de pigments organiques à bas point de fusion et permet de réaliser simplement la transformation en film tout en maintenant simultanément la planéité du substrat.
