    摘要： The present invention relates to pigments comprising (A) a platelet-shaped substrate (S), (B) a coating comprising two different metal oxides having a difference in refractive index of at least 0.1, wherein the metal oxide having a higher refractive indexis the metal oxide MOH and the metal oxide having a lower refractive index is the metal oxide MOL, wherein the amount of MOH and the amount of MOL changes (continuously), (C) a coating comprising metal oxides MOH and MOL, wherein the amount of MOH and the amount of MOL changes (continuously), and (D) optionally an outer protecting layer; a process for their production and their use in paints, ink-jet printing, for dyeing textiles, for pigmenting coatings (paints), printing inks, plastics, cosmetics, glazes for ceramics and glass. The pigments can show enhanced colour chroma while maintaining the lightness of coventional interference pigments, or vice versa.

    摘要： The invention relates to aluminum pigments which are at least partly coated with lubricant. Said aluminum pigments have a) a water spreading coefficient ranging between 40,000 and 130,000 cm2/g, b) an average thickness h of less than 100 to 30 nm, said average thickness h being calculated from the water spreading coefficient and by counting the thickness from the h50 value of the cumulative passage distribution by means of scanning electron microscopy, c) a relative range of the thickness distribution Δh of 70 to 140 percent, which is determined by counting the thickness by means of scanning electron microscopy and is calculated according to formula (I) based on the corresponding cumulative passage graph of the relative frequencies, d) a form factor d50/h of more than 200, e) a peak-to-valley value of 0.30 to 0.9, said peak-to-valley value being calculated from the specific surface that is measured according to the BET method and the spreading coefficient in accordance with formula BET value/2 x spreading coefficient. The invention further relates to a method for producing said aluminum pigments and uses thereof.

    摘要： To provide a camouflage active component that can be utilized in for example skin camouflage or camouflage paint to provide both visual and thermal camouflage, the present invention presents a low emissive camouflage flake (1, 2) wherein a metal layer (11, 21) having reflective properties in the thermal radiation range is coated with a coloured coating (13, 23) having transparency properties in the thermal radiation range. The metal layer (11,21) gives the camouflage flake (1,2) its low emission properties in the thermal radiation range while the coloured coating (13, 23) absorbs and or reflects radiation in certain parts of the visible radiation range, thereby giving the camouflage flakes (1, 2) a desired colour. The low emissive camouflage flake (1, 2) may also comprise a stabilizing film (25), such as a polyester film, to simplify the manufacturing of the flakes.
