Definitions

  • the invention relates to a ceramic toner which can be transferred by means of electrophotographic printing to a glass, glass ceramic or ceramic substrate with high temperature resistance and can be baked in a subsequent temperature process and which, in addition to glass flow particles, also contains color pigment particles.
  • WO 98/39272 and EP 0 647 885 B1 show, ceramic color compositions are used for decorating ceramic and glass products which are applied to a paper support as a transfer agent in the electrophotographic reproduction process.
  • the paper backing is coated with gum arabic, poly vinyl acetate or wax.
  • the coloring substances copied onto the paper backing are applied to the glassy or ceramic
  • the paper carrier burns. This in-direct printing process is cumbersome and a completely residue-free burning of the paper carrier is not always guaranteed. These residues often lead to rejects.
  • the ceramic colors specified in these publications are specially designed for the decoration of ceramic articles. The colors cannot be used on special glass, glass ceramics and glasses with low thermal expansion.
  • the toner has:> 30 to 80% by weight, in particular 45 to 60% by weight, of a special glass frit,
  • This toner has a composition of a glass frit and inorganic pigments, which is especially tailored to the printing of glass, glass ceramic or ceramic. This overcomes the disadvantageous liability problems in the prior art when printing on special glasses.
  • the toner can in particular have a thermoplastic plastic matrix that melts homogeneously on the substrate in the temperature range from 100 ° C. to 400 ° C. and in the temperature range from 300 ° C. to 500 ° C. evaporates and / or burns out almost completely.
  • the toner can have flow aids, with the aid of which the wetting of the printable
  • Substrates can be controlled.
  • the plastic matrix as a carrier of the inorganic glass frits and pigments can be selected by the choice of melting, decomposition and / or vaporization.
  • the temperature of the plastic used must be adapted to the burn-in process so that the plastic melts homogeneously onto the substrate before it burns out and then evaporates and / or decomposes and does not hinder the melting together of the glass flux and color pigment particles.
  • the toner image can be transferred directly to the substrate in electrophotographic printing
  • the percentages by weight refer in particular to the total weight of the toner, in particular in the case of one-component toner.
  • the carrier is not taken into account in the weight composition information.
  • 3 to 25% by weight of toner are used in commercially available two-component toners.
  • the rest (75 to 97% by weight) make up the carrier.
  • the percentage by weight is
  • the flow in the total two-component toner is between 3 and 8% by weight (10% by weight • 30% by weight or 80% by weight • 10% by weight).
  • the pigment content is accordingly in the range between 0 and 2% by weight.
  • the proportion of binder resin is between 3 and 5% by weight.
  • toner is transferred indirectly.
  • a transfer agent for example paper coated with gum arabic, is then used.
  • the toner has no coloring pigments, so that the proportion of the glass frit is in the range between 50 to 70% by weight and the proportion of the plastic matrix is in the range between 30 and 50% by weight.
  • the plastic matrix has toner resins based on acrylate, in particular styrene acrylate, polymethyl methacrylate. These substances are easy to process and have good adhesion to the substrate. In addition, these substances burn without residue.
  • the influence of the depolymerization, the melting, the evaporation and / ⁇ o or decomposition temperature can be achieved by choosing different polymers for the plastic matrix. Suitable materials are polyvinyl alcohol, polyoxymethylene, styrene copolymers, polyvinylidene fluoride, polyvinyl butyral, polyester (unsaturated and / or saturated or mixtures thereof), polycarbonate, polyvinylpyrrolidone, vinylimidazole copolymers and polyether.
  • the toner can additionally contain charge control substances and / or oxidizing agents in a known manner to improve the image transfer or to decompose the organic without residues.
  • the added oxidants accelerate the thermal decomposition of the plastic matrix.
  • the toner is additionally coated with additives to improve the wetting when the toner melts on the generally relatively polar and smooth, unlike paper, non-absorbent surface.
  • additives to improve the wetting when the toner melts on the generally relatively polar and smooth, unlike paper, non-absorbent surface.
  • the polarity of the toners between non-polar, hydrophobic, neutral, polar, hydrophilic, and thus the wetting of the substrates can be controlled via a suitable choice of known additives.
  • Known flow aids such as aerosils and transfer aids can be used to improve the quality of the print.
  • the proportion of such auxiliaries is between 0 and 1.0% by weight, typically between 0.2 and 0.5% by weight.
  • peroxides or azo compounds can be added to the toner, but these have decomposition temperatures> 150 ° C., so that the decomposition does not start during the melting phase (fixing phase).
  • inorganic additives are also possible, for example catalytically active pigments, which accelerate the decomposition of the organic plastic matrix. Examples of this are so-called perovskites of the general form ABO 3 , for example LaMnO 3 , LaCoO 3 , La ⁇ Sr / , Co Mn ⁇ 5 O 3 + e .

  • the table below shows exemplary embodiments of glass compositions (frits or rivers) which are particularly suitable for a ceramic toner. The percentages by weight relate in each case to the composition of the glass frit.
  • Glass compositions 1 to 6 are particularly suitable for glass and glass ceramics.
  • glass composition 1 Special exemplary embodiments for glass composition 1 are:
  • glass composition 2 Special exemplary embodiments for glass composition 2 are:
  • Glass composition 7 is particularly suitable for glass ceramics in secondary firing.
  • Glass composition 8 to 10 is particularly suitable for glass.
  • Glass composition 11 to 12 is particularly suitable for ceramics. Earthenware. Bone china and porcelain.
  • composition ranges 1 and 2 properties of these glass frits are specified which relate in particular to the special requirements for the direct printing of glass ceramics with an expansion coefficient of less than 2x60 6 K 1 (in the temperature range from 20 to 700 ° C). Mixtures of the above glass frits are also conceivable depending on the application.
  • these glass frits are particularly suitable in combination with appropriate inorganic pigments for the electrophotographic printing of special glass plates, such as soda lime glass or
  • Borosilicate glass (if necessary, each previously coated, for example, with SiO 2 and / or with TiO 2 or with one of the above-mentioned glass frits, for example for the use of oven front panes, oven inner panes, refrigerator shelves, counter glass etc., as well as for direct printing on glass ceramics with low expansion, for example for applications such as glass-ceramic cooktops or grilling surfaces or fireplace viewing panes, but can also be used to print directly on ceramic surfaces such as tiles or sanitary objects. Requirements regarding abrasion resistance, adhesion and chemical resistance are taken into account with the glass frit composition according to the table.
  • Color pigments typically include inorganic compounds, such as metal oxides, mixed phases metal oxide pigments or CIC pigments (complex inorganic color pigments), inclusion pigments, metal powders or flakes, metal colloids, pearlescent or luster pigments based on mica or glassy or SiO 2 - or Al 2 O 3 platelets, fluorescent pigments, magnetic pigments, anti-corrosive pigments, transparent pigments, sintered pigments and / or mixtures of pigments with glass frits, pigments for four-color sets, etc. or mixtures of the above-mentioned variants, which are already considered sufficient in the literature (eg "Ullmann's Encyclopedia of Industrial Chemistry ", vol. A20, 1 992, VCH Publishers, Inc.).

  • Examples of grinding processes for the production of such particles are counter-jet grinding, grinding in ball, annular gap or pin mills.
  • the glass flow particles as well as the pigments are typically only partially from the plastic matrix due to the manufacturing process of the toner, i.e. incompletely encased, and usually have an irregular shape. This is due in particular to the fact that the inorganic constituents (glass flux and pigments) have different fracture toughnesses compared to the organic plastic matrix and preferentially break open at the grain boundaries during the grinding process of the toner. Additional additives or flow aids that are added later accumulate on the surface of the plastic matrix or on the exposed flux and / or pigment particles.

Abstract

L'invention concerne un toner céramique pouvant être transféré sur un substrat en verre, en vitrocéramique ou en céramique, très thermorésistant, par impression électrophotographique et pouvant être cuit, dans le cadre d'un processus thermique subséquent. Ledit toner céramique contient, outre des particules de fondant spéciales, également des particules de pigments colorés. Il est prévu, selon l'invention, que ledit toner présente une matrice thermoplastique qui fond sur le substrat dans une plage de températures allant de 100 à 400 DEG C, s'évapore pratiquement sans résidus dans une plage de températures allant de 300 à 500 DEG C et/ou se décompose. On obtient ensuite un toner pouvant être transféré, notamment en mode d'impression directe et ne présentant pratiquement pas de résidus de la matrice plastique, après cuisson.
