Definitions

  • the present invention relates to a pigment mixture consisting of at least two components, where component A comprises coated un or singly or multiply coated glass flakes and component B comprises coated or uncoated BiOCl pigments or pearlescent pigments based on phyllosilicates, SiO 2 - or F ⁇ 2 ⁇ 3 - or A ⁇ Os platelets, as well as their use, inter alia, in paints, inks, printing inks, plastics, powder coatings, ceramic glazes, plastic films and cosmetic formulations.
  • Pearlescent pigments are thin platelets of a colorless or colored transparent or semi-transparent material. Pearlescent pigments based on mica platelets have been known for more than 30 years.
  • Pearlescent pigments based on glass platelets have a much higher gloss and a significantly higher brilliance than pearlescent pigments based on mica. The reason for this is that the glass plates have a better plane-parallel surface required for the reflection.
  • the object of the present invention is to increase the processability of glass platelets, in particular in technical applications. Surprisingly, it has now been found that it is possible to combine the advantageous performance properties of commercial pearlescent pigments based on mica, SiO 2 or Al 2 O 3 with the good luster and glitter properties of pearlescent pigments based on glass flakes, if coated or uncoated
  • the pigment mixture of the invention is characterized by a very strong glitter and a strong brilliance, can be very well incorporated into the various application media and achieved excellent hiding power.
  • the mixing ratio of component A and component B is preferably from 10:90 to 50:50.
  • Preferred mixtures contain components A and B in the ratios 10:90, 20:80, 25:75, 30:70, 40:60 and 50:50
  • Component A is contained in the pigment mixture of the invention to a maximum of 50% by weight.
  • the present invention thus relates to a pigment mixture comprising at least two components, component A comprising uncoated or mono- or multi-coated glass flakes and component B coated or uncoated BiOCl pigments and / or pearlescent pigments based on phyllosilicates, SiO 2 -, Fe 2 O. 3 - or AI 2 O 3 platelets are.
  • the invention also relates to the formulations containing the pigment mixture according to the invention.
  • the pigment mixture according to the invention contains glass platelets.
  • the glass flakes are provided with one or more layers of metal oxides, metal sulfides, metal oxynitrides, Metal suboxides, metals and their mixtures completely or partially coated.
  • Suitable pearlescent pigments based on coated glass flakes are known, for example, from WO 97/46624, WO 02/090448 A2 and
  • the thickness of the glass platelets is preferably ⁇ 1 ⁇ m, in particular ⁇ 0.9 ⁇ m, and very particularly preferably ⁇ 0.8 ⁇ m.
  • the glass slides may be covered with one or more layers.
  • the glass platelets are preferably coated with colored or colorless metal oxides, metal hydroxides, metal suboxides or oxynitrides. Suitable metal oxides are in particular TiO 2 , Fe 2 O 3 , Fe 3 O 4 , FeO (OH), SnO 2 , Cr 2 O 3 , ZrO 2 , ZnO, CuO, NiO, vanadium and manganese oxides and other metal oxides alone or in a mixture in a single layer or in successive layers. Also suitable for occupying titanium suboxides and titanium nitrides.
  • Preferred coated glass flake pigments have the following structure:
  • a semitransparent layer of a metal may also be used.
  • Suitable metals for this purpose are, for example, Cr, Ti, Mo, W, Al, Cu, Ag, Au or Ni.
  • finely divided particles in the nanometer size range in layers.
  • finely divided TiO 2 or ZnO or finely divided carbon (carbon black) with particle sizes in the range from 10 to 250 nm have proved to be suitable.
  • the light-scattering properties of such particles also make it possible to influence the gloss and hiding power in a more targeted manner.
  • Particularly preferred glass flakes are platelets or glass flakes coated with TiO 2 and / or Fe 2 O 3 , which initially have an SiO 2 layer and are subsequently coated with TiO 2 and / or Fe 2 O 3 .
  • Suitable glass flakes can be produced as described for example in patent literature EP 0 289 240 B1, WO 97/46624, WO 02/090448 A2, WO 03/006558 A2 and WO 2004/055119 A1.
  • coated or uncoated glass flakes are admixed to component B preferably in amounts of 1-50% by weight, in particular 3-25% by weight and very particularly preferably 5-15% by weight.
  • component B preferably in amounts of 1-50% by weight, in particular 3-25% by weight and very particularly preferably 5-15% by weight.
  • the particular composition of the pigment mixture according to the invention is dependent on the application medium to be pigmented and the desired effect.
