ABSTRACT:
The subject of the invention is an effect pigment which is coated with surface-modifying agents, wherein the initial pigment has a layer with at least one reactive surface-modifying agent, wherein the surface-modifying agent is a compound which has at least two functional groups which are different from each other and which are spaced by a spacer, chemically bound to the initial pigment. Also described is a process for the production of an effect pigment of that kind.
