Definitions
- the present invention relates to semitransparent neutral body color interference pigments comprising a substrate and a coating comprising metallic tin and additionally at least one metal oxide
- effect pigments are substrates, for example of metals, mica or synthetic platelets of SiO 2 , glass or Al 2 O 3 , which are coated with one or more layers, for example of metals or metal oxides.
- metal oxides are commonly used layer materials, since they can be applied to the substrates by precipitation and are largely chemically inert.
- One common metal oxide used is titanium dioxide.
- the rutile modification of the titanium dioxide is the preferred modification. In order to achieve the highest possible degree of rutilization, the titanium dioxide layer is precipitated onto a previously applied tin dioxide layer. The tin dioxide controls the crystallization of the precipitated titanium dioxide layer in the modification of the rutile.
- a particular example of reduction pigments are the tin-containing gray pigments described in DE 195 22 267, which are obtainable by pyrolysis of substrates coated with tin dioxide and at least one further metal oxide and colloidal organic particles. The pyrolysis takes place at temperatures of 900-1100 0 C and oxygen exclusion.
- the pigments described there show a gray body color and a silver interference, when tilted to flat angles they also show a blue cast or a yellowish to brownish color. The resulting blue cast is due to the formation of
- Body color and silver interference which have a high gloss and show no blue color from any viewing angle, and thus are color-neutral overall.
- the present invention accordingly provides semitransparent neutral body color interference pigments comprising a substrate and a coating comprising metallic tin and additionally at least one metal oxide.
- the pigments of the invention show a high gloss, are gray and show no bluish cast, no matter from which viewing angle. In addition, they show a noble-looking, e.g. silver interference.
- the metallic tin-containing coating is free of carbon or other impurities resulting from reduction with hydrocarbons or metals, e.g. Lithium, sodium, calcium or other metals.
- bleeding effects, or effects in which certain components of the pigments diffuse to the surface of the pigment or completely out of the pigment do not occur.
- a process for the preparation of the interference pigments according to the invention wherein a substrate coated with a tin dioxide-containing and optionally additionally containing at least one further metal oxide coated substrate is reacted in a reducing gas mixture of nitrogen and hydrogen to form metallic tin.
- the pigments of the invention are versatile.
