Abstract
Metal-effect pigment including a metallic, plate-shaped core, which is coated with at least one polymer layer, wherein the polymer layer is homogeneous polyurea-type polymer, wherein the polyurea-type polymer of the polaner layer is obtained by an addition reaction of a component A with a component B, wherein component A includes molecules including 1-20 primary and/or secondary amino groups and component B includes molecules including 1-20 isocyanate groups.
