Effect pigments for e.g. paints, coatings or tracers, comprises inorganic flake-form substrates that are uniform in shape and size and that have circular or elliptical shape or polygon shape

摘要

Effect pigments of uniform shape and size based on a flake-form inorganic substrate, comprises inorganic flake-form substrates that are uniform in shape and size and that have a circular or elliptical shape or a polygon shape. Effect pigments of uniform shape and size based on a flake-form inorganic substrate, comprises inorganic flake-form substrates that are uniform in shape and size and that have a circular or elliptical shape or a polygon V nshape, where n is the number of corners and is =3. An independent claim is also included for a process of preparing effect pigments, comprising applying a film comprising a substrate precursor to a structured support having structuring in circular or elliptical shapes or in the shape of the polygon V n; solidifying the film by drying; developing a substrate by chemical reaction from the substrate precursor; removing the substrate from the structured support; and optionally washing, drying and/or calcining the substrate.
