relates to a printed image comprising flake-form effect pigments which has striking matt/gloss effects, to a process for the production of a printed image of this type, and to the use thereof, in particular in security printing. ## Claims ### Claim 1 A printed image comprising at least two printed area units on a substrate, wherein each of the area units comprises flake-form effect pigments and a binder, a first printed area unit comprising solidified area of a first printing ink comprising a first flake-form effect pigment, said first flake-form effect pigment being based on coated support flakes and having an outermost layer consisting of a non-metallic, inorganic material, and a second printed area unit comprising a solidified area of a second printing ink comprising a second flake-form effect pigment, which is based on coated support flakes and has an outermost layer comprising an organic surface modifier, and wherein said first and second printed area units are visible simultaneously to the naked eye and optically distinguishable from one another when viewing the substrate on a surface carrying the printed image at any viewing angle and have different flop indicies from one another, said first flake-form effect pigments are arranged in random distribution in the first printed area unit and said second flake-form effect pigments are aligned parallel to the substrate at the surface of the second printed area unit. ### Claim 2 (depends on 1) The printed image according to claim 1, wherein the first and second area unit are directly adjacent to one another. ### Claim 3 (depends on 1) The printed image according to claim 1, wherein the organic surface modifier comprises organofunctional siloxanes. ### Claim 4 (depends on 3) The printed image according to claim 3, wherein the organo-functional siloxanes contain fluoroalkyl groups and aminoalkyl groups. ### Claim 5 (depends on 1) The printed image according to claim 1, wherein the second flake-form effect pigment below the outer layer comprising an organic surface modifier has a layer comprising a non-metallic, inorganic material. ### Claim 6 (depends on 1) The printed image according to claim 1, wherein the first and second flake-form effect pigment differ merely through the outer layer comprising an organic surface modifier on the second flake-form effect pigment. ### Claim 7 (depends on 1) The printed image according to claim 1, wherein the first and second flake-form effect pigment are pearlescent pigments, interference pigments, metal-effect pigments or optically variable pigments. ### Claim 8 (depends on 7) The printed image according to claim 7, wherein the first and/or second flake-form effect pigments also have magnetic, electrically conductive or luminescent properties. ### Claim 9 (depends on 1) The printed image according to claim 1, said image having a laser marking. ### Claim 10 (depends on 9) The printed image according to claim 9, wherein the laser marking is located on the first and/or second area unit. ### Claim 11 (depends on 1) The printed image according to claim 1, wherein the substrate is paper, cardboard, wallpaper, tissue material, plastic, metal, ceramic, glass, wood, textile material or a composite material comprising two or more of the above-mentioned materials. ### Claim 12 (depends on 11) The printed image according to claim 11, wherein the paper is banknote paper. ### Claim 13 (depends on 12) The process according to claim 12, wherein the first and/or second printing ink is a screen printing ink, a gravure printing ink, a flexographic printing ink or an intaglio printing ink. ### Claim 14 (depends on 1) A process for the production of a printed image according to claim 1, comprising applying to a substrate a first printing ink, comprising a first flake-form effect pigment, which is based on a coated support flake and has an outermost layer consisting of a non-metallic, inorganic material, and a binder, forming a solidified first area unit of a printed image, and applying to the substrate a second printing ink, comprising a second flake-form effect pigment, which is based on a coated support flake and has an outermost layer comprising an organic surface modifier, and a binder forming a solidified second area unit of a printed image, where the first and second area units are applied to the substrate at a separation from one another so that they are simultaneously visible to the naked eye and optically distinguishable from one another when viewing the substrate on a surface carrying the printed image at any viewing angle, and where the first and second area units have different flop indicies from one another. ### Claim 15 (depends on 14) The process according to claim 14, wherein the first and second area unit are applied to the substrate directly adjacent to one another. ### Claim 16 (depends on 14) The process according to claim 14, wherein the outer layer of the second effect pigment comprises organofunctional siloxanes. ### Claim 17 (depends on 16) The process according to claim 16, wherein the organofunctional siloxanes are siloxanes which contain fluoroalkyl groups and aminoalkyl groups. ### Claim 18 (depends on 14) The process according to claim 14, wherein the first and/or second area unit are provided with a laser marking. ### Claim 19 (depends on 1) A product having a decoration element, functional element or security feature, said decoration element, functional element or security feature comprising a printed image according to claim 1. ### Claim 20 (depends on 19) The product according to claim 19, that is banknotes, cheques, credit cards, shares, passports, identity documents, driving licences, entry tickets, revenue stamps, labels, packaging materials or seals.
