Definitions
- the invention relates to a luster pigment and to a process for its production, in which a multilayer film is produced by vacuum evaporation of a base and, after detachment from the base, the particles thus produced to pigment particles of the desired size
- Gloss pigments are widely used, in particular for decorative purposes, automotive coatings, cosmetic purposes or in the field of security printing.
- an inorganic metal salt e.g. Sodium chloride
- the intermediate layer which enables subsequent detachment from the base, several layers being subsequently vapor-deposited in the CVD or PVD process, and the layer composite formed in this way being detached after leaving the vacuum region by dissolving the intermediate layer with water in the form of individual particles ,
- a device for performing such a method in which a circumferential metal strip is used as the carrier, is known from the unpublished German patent application 199 02 141.
- a reflection layer or carrier layer is also described there to be made of aluminum by vapor deposition, after which a transparent layer, for example made of magnesium fluoride or titanium oxide, is evaporated.
- the vapor-deposited layers consist of the group of zinc sulfide, zinc oxide, guanine, magnesium fluoride, titanium dioxide, calcium fluoride and cryolite, a substance from the group of alkali halides, alkaline earth metal halides or alkali borates, such as, for example, as the carrier substance for these films Na 2 B 0 7 ; B 2 0 3 ; MgCI 2 is used.
- the evaporation temperatures depend on the pigment-forming substance or carrier substance.
- Interference phenomena are used to form colors by taking advantage of the path difference of the light waves due to the reflection at the interface created by the various vapor-deposited layers. These interference effects are influenced by the thickness of the individual layers and their refractive index. For an undyed pearlescent pigment, for example, the product of film thickness in nm and refractive index should remain in a range between 10 and 200.
- Interference colors are produced when the value of this product falls in the range above 200, with the strongest colors occurring at a given pigment concentration by weight in the range from 200 to about 1500.
- the color intensity also depends on the uniformity of the platelet thickness, ie on the plane parallelism of the carrier material and the plane parallelism of the vapor-deposited layers, since pigment platelets of uneven thickness reflect different colors, which differ can cancel on the other side, so that a color effect does not occur or at least no pure colors are generated.
- a thin film illuminated with white light can show changing colors over the entire spectrum of visible light from red to blue if the observer changes his viewing angle in the direction of flat angles. It is also shown mathematically that a larger thickness scatter leads to less defined colors.
- newer pearlescent pigments based on artificially produced aluminum oxide and silicon oxide substrates have a constant thickness and thus become part of the optical system. Multi-layer oxide coatings based on Si0 2 substrates show stronger and clearer interference colors than when using mica as a substrate.
- the deposition from the liquid phase or from the gas phase leads to a significant porosity of often more than 25% of the layer. This porosity weakens the intensity of the reflected light.
- Ti0 2 flakes For the production of Ti0 2 flakes, it is known to break open continuous films which are produced, for example, by thermal hydrolysis of TiOCl 2 . Alternative options are to apply titanium alkoxides to a surface and to break up the resulting film by steaming, to apply colloidal TiO 2 solution to a glass surface and to scrape off the resulting film. Also described is the application of TiOCl 2 solution to a gelatin film and detachment of the gelatin film, vacuum deposition, treatment of Kalramtitanat fibers with acid and subsequent heating or production and breaking up of hollow Ti0 2 particles from the mixture of a surfactant with a colloidal Ti0 2 solution. Substrate-free Ti0 2 flakes can also be obtained by dissolving the substrates in strong acids or bases.
- Ti0 2 -coated mica When producing Ti0 2 -coated mica from a TiOCl 2 solution, great attention must be paid to the reactor geometry and the mixing conditions.
- the Ti0 2 layers obtained can be coated with organic dyes as well as with thin layers of silver, nickel or mixtures of different metals in order to produce a darker tone.
- DE-AS 1 136 042 From DE-AS 1 136 042 it is known to support substances with a low refractive index in the form of oxides or oxide hydrates of metals of IV. and / or V. group, for example Si0 2 , and to coat them with substances with a higher refractive index, for example oxides of Ti, Fe, Sb, Sn etc.
- the production of the platelets described there is accomplished by first wetting a support made of glass, ceramic mass, metal or plastic with a solution of a hydrolyzable compound of the metal to be converted into the desired oxide, the resulting film being subsequently heated that respective oxide or hydrated oxide is formed as a thin coating.
- silicon oxide layers are vapor-deposited on platelet-shaped particles which are produced in a conventional manner and have a length of, for example, 1 to 200 ⁇ m.
- the plates should consist of metallic reflective material or metal alloys. Alternatively, the use of mica is considered.
- a supporting base of a colorless oxide layers of titanium oxide in crystalline ⁇ lized form, for example as rutile apply. If necessary, a another layer of a colored inorganic substance, such as iron oxide, can be applied.
- the object of the invention is to create a method for producing a glossy pigment or a glossy pigment which can be produced at a high production rate, is distinguished by very good durability properties and by a wide range of possible colors with high color saturation and opacity ,
- this object is achieved in that at least one carrier layer, in particular a silicon oxide carrier layer, and at least one metal oxide layer, in particular titanium oxide layer, are evaporated onto the base, in particular a circumferential metal strip.
- a carrier layer is created which, after detachment from the base, that is to say the metal strip, is replaced, in particular, by a Chen mica platelets, but also to platelets produced by the wet process, high plane parallelism and defined thickness.
- the SiO starting material used according to the invention has no impurities, e.g. by
- the simple production of the backing layer according to the invention also has advantages over synthetic mica (phlogopite), which due to its complex production at high pressure and high temperature has never attained any commercial importance.
- optical properties such as refractive index and reflection coefficient of the support layer can be set by the vapor deposition rate and the oxygen partial pressure, and it is thereby possible to generate defined and reproducible color tones and color changes depending on the viewing angle.
- the subsequently vapor-deposited layer in particular a titanium oxide layer, can also be adjusted as desired with regard to its thickness via the vapor deposition rate and / or the belt speed of the metallic carrier tape and, due to the flat surface of the previously vapor-deposited silicon oxide layer, also has a good plane parallelism.
- pigments produced according to the invention are plane-parallel up to the outer edge. This results in a higher color purity and a better gloss, even with smaller particles, since the proportion of scattered edges is minimized.
- the manufacturing process according to the invention leads to the fact that the
- the pigments obtained according to the invention are very shear stable. This results from the fact that a very good bond between the SiO and TiO layers is obtained in the process according to the invention. In contrast, the shear stability of pigments based on natural mica is very poor owing to the fact that the mica is black and the morphology of the metal oxide layer.
- the thickness of both layers can be easily adjusted, in particular in comparison to the hydrolysis band process (shrinkage of the applied layer) and this can influence the color, the thickness of the SiO layer influencing the color even more than the thickness of the TiO 2. Layer.
- the carrier layer is surrounded on both sides by metal oxide layers which can have a different layer thickness (asymmetrical layer structure).
- a layer structure can be determined by wet chemical ⁇ L ⁇ 'I " I
- a metal layer in particular an aluminum layer, is again evaporated onto a three-layer arrangement described above, a high covering power of such pigments being achieved by a correspondingly set layer thickness.
- a relatively thin silicon oxide layer can be vapor-deposited as a protective layer on the aluminum layer in a manner known per se.
- Another embodiment provides for a metal oxide layer and the carrier layer to be followed by a metal layer, a silicon oxide layer and a further metal oxide layer, it being possible for the metal layer to consist of aluminum, chromium, gold, copper, silver or the like.
- a further variant provides that ⁇ on the metal oxide layer and the Trä- ⁇ ⁇ carrier layer, a metal layer follows, where the metal may be aluminum, in turn, environmentally chromium, gold, copper, silver or the like.
