Abstract
The present invention relates to electrically conductive, coloured interference pigments, in particular flake-form interference pigments, which have an outermost layer which comprises crystalline carbon in the form of graphite and/or graphene, to a process for the preparation of such pigments, and to the use of the pigments prepared in this way.
Claims17
Electrically conductive, coloured interference pigments based on a flake-form support, where the support has a coating comprising one or more layers and where the outermost layer furthest remote from the support consists of at least 95% by weight, based on the weight of this layer, of carbon and comprises crystalline carbon in the form of graphite and/or graphene.
