    Abstract: PROBLEM TO BE SOLVED: To provide an interference pigment which are universally suitable for a large number of very different application and expressing color effects which exhibit color flops, and to provide a method of preparation, and a method of using thereof. SOLUTION: The multilayered interference pigment comprises a platelet-shaped substrate which is coated with alternating layers of materials of high and low refractive index, wherein the total thickness of the interference pigment is not greater than 1 μm. The substrate includes synthetic flake, and the diameter is 1-250 μm and the thickness is 100-600 μm. The process for the preparation of these pigments, in which a substrate is coated alternately with layers of materials of high and low refractive indexes, where the thickness of the layers of materials of high and low refractive indexes are selected in such a way that the total thickness of the interference pigment does not become greater than 1 μm. The interference pigments are used in cosmetics, paints, coatings, plastics, films, in security printing, in security features in documents and identity cards, for coloring seed, for coloring foods or in medicament coatings, and for the preparation of pigments composition and dry preparations.
