- Suitable layer materials for layer (ii) with a refractive index greater than 1.8 are preferably metal oxides or metal oxide mixtures, such as Ti0 2 , Fe 2 O 3 , Zr0 2 , ZnO, SnO 2 or compounds with a high refractive index such as iron titanates, Iron oxide hydrates, titanium suboxides, chromium oxide, bismuth vanadate, cobalt aluminate and mixtures or mixed phases of the compounds mentioned with one another or with other metal oxides.
- Metal sulfides, metal nitrides or metal oxynitrides are also suitable.
- the thickness of layer (ii) is 10-550 nm, preferably 15-400 nm and in particular 20-350 nm.
- the metal layers (iii) consist of metals, e.g. Aluminum, chrome, nickel, chrome-nickel alloys or silver. Chromium and aluminum are preferred because they are easy to separate.

- the pigments according to the invention contain additional colorants in the coating. If, for example, carbon black particles are used, then particle sizes of 5 to 200 nm and in particular 10 to 100 nm are used. Such pigments, which preferably soot particles in
- the pigments according to the invention can also contain particles of titanium dioxide, aluminum oxide, silicon dioxide, tin dioxide, magnesium oxide, zinc oxide, cerium dioxide, tungsten oxide, molybdenum oxide, zirconium oxide, but also mixed oxides such as Cr 2 FeO 4 , CoAI 2 0 4 or NiAI 2 0 4 Coating included.
- organic pigment particles can also be contained in the coating, with temperature-stable organic pigments being preferred in particular.
- the organic pigment particles used are preferably phthalocyanines, laking products of basic dyes with heteropolyacids, anthraquinones, phenazines, phenoxazines, diketopyrrolopyrroles or perylenes.
- all pigments that have been described for incorporation into the substrate can also be incorporated into the coating of the pigment according to the invention.
- the incorporation of small metal oxide or organic pigment particles with an average size of 10 to 40 nm into the cavities of the metal oxide coating brings about a significant increase in the hiding power and the gloss, combined with a high homogeneity of the coating compared to pigments which are obtained by mixed precipitation .
- the hiding power and, in the case of colored pigment particles, the observation color-dependent absorption color of the pigments according to the invention can be varied within a wide range by the concentration of the pigment particles incorporated.
- the mass fraction of the incorporated pigment particles, based on the coating is between 0.5 and 30% and in particular between 2 and 20%. Further information on pigments which contain pigment particles in the coating can be found in DE 41 40 295.
- the finished pigment can be provided with a post-coating or post-treatment (iv) which further increases the light, weather and chemical stability, or the handling of the pigment, in particular familiarization with different media is made easier.
- a post-coating or post-treatment are, for example, the processes described in DE-PS 22 15 191, DE-OS 31 51 354, DE-OS 32 35 017 or DE-OS 33 34 598.
- the additional substances applied make up only about 0.1 to 5% by weight, preferably about 0.5 to 3% by weight, of the total pigment.
- the number and thickness of the layers depends on the desired effect and the substrate used. The number of layers is limited by the economy of the pigment. If the substrate used is Ti0 2 platelets which are produced on an endless belt by the process described in WO 97/43346, particularly well-defined interference effects can be achieved since these Ti0 2 platelets have a uniform layer thickness.
- the reflection or transmission spectrum of such a pigment has finer and more precisely tunable structures than the spectrum of a corresponding pigment, which is based on a substrate with a broad thickness distribution, such as mica.
- the TiO 2 platelets are produced according to WO 97/43346 on an endless belt by solidification and hydrolysis of a titanium tetrachloride solution.
- the metal oxide layers are preferably applied wet-chemically, it being possible to use the wet-chemical coating processes developed for the production of pearlescent pigments; Such processes are described, for example, in DE 14 67 468, DE 19 59 988, DE 20 09 566, DE 22 14 545, DE 22 15 191, DE 22 44 298, DE 23 13 331, DE 25 22 572, DE 31 37 808 , DE 31 37 809, DE 31 51 343, DE 31 51 354, DE 31 51 355, DE 32 11 602, DE 32 35 017 or in other patent documents and other publications.
- the substrate particles are suspended in water and mixed with one or more hydrolyzable metal salts at a pH value suitable for the hydrolysis, which is chosen so that the metal oxides or metal oxide hydrates are deposited directly on the particles without causing co-precipitation .
- the pH value is usually kept constant by simultaneously adding a base.
- the pigments are then separated off, washed and dried and, if appropriate, annealed, it being possible to optimize the annealing temperature with regard to the coating in each case. If desired, the pigments can be separated off, dried and, if necessary, annealed after applying individual coatings, in order then to be resuspended to precipitate the further layers.
- the coating can also be carried out in a fluidized bed reactor by gas phase coating, with e.g. the methods proposed in EP 0 045 851 and EP 0 106 235 for the production of pearlescent pigments can be used accordingly.
- aqueous titanium salt solution is slowly added to a suspension of the material to be coated, which is heated to about 50-100 ° C., in particular 70-80 ° C., and largely becomes by adding a base, such as, for example, aqueous ammonia solution or aqueous alkali metal hydroxide solution constant pH of about 0.5-5, especially about 1, 5-2.5 maintained.
- a base such as, for example, aqueous ammonia solution or aqueous alkali metal hydroxide solution constant pH of about 0.5-5, especially about 1, 5-2.5 maintained.
- This method also known as the titration method, is characterized in that an excess of titanium salt is avoided. It will achieved by supplying only such an amount of hydrolysis per unit of time as is required for a uniform coating with the hydrated TiO 2 and as per unit of time can be absorbed by the available surface. There are therefore no hydrated titanium dioxide particles that are not on the surface to be coated
- a sodium silicate solution is added to a suspension of the material to be coated, which is heated to about 50-100 ° C., in particular 70-80 ° C.
- the pH is kept constant at 4 to 10, preferably 6.5 to 8.5.
- stirring is continued for a further 30 min.
- the individual layers can also by known methods
- metals for example of aluminum or chromium, or of alloys, such as, for example, Cr-Ni alloys, and of metal oxides, for example of titanium oxide, silicon oxide, or indium-tin oxide, or by thermal evaporation of metals, metal oxides or acrylates.
- a vacuum tape coating as described in DE 197 07 805 and in DE 197 07 806 for the production of interference pigments is preferred.
