    摘要： The invention relates to aluminum pigments which are at least partially coated with lubricant, wherein the aluminum pigments have a relative breadth of thickness distribution Δh of from 30% to less than 70%, as determined by a scanning electron microscope thickness count and as calculated on the basis of the corresponding cumulative breakthrough curve of the relative frequencies of occurrence, according to the formula Δh=100×(h90−h10)/h50, and an X-ray diffractogram, measured on pigments in substantially plane-parallel orientation, having one or two main peaks which do not correspond to the [111] reflexes.
    The invention further relates to a method for the production of said aluminum pigments and to uses thereof and also to nail varnishes and printing inks containing said aluminum pigments of the invention.

    摘要： The invention relates to a surface-modified effect pigment comprising particular additives and to the production thereof. The present invention further provides a nail varnish composition comprising a) at least one effect pigment that has been surface-modified with a starting material (additive), where the effect pigment comprises a substrate in platelet form and optionally at least one coating applied to the substrate, b) at least one hydrocarbon resin as binder, and c) at least one solvent or solvent mixture, where the starting material (additive) for surface modification of the effect pigment is at least one compound taken from the group consisting of phosphoric ester-containing, phosphonic ester-containing, phosphonic acid-containing, fatty acid-containing and/or silane-containing compounds or mixtures thereof.

    摘要： The invention relates to coated effect pigments, wherein the coating comprises a binder which is suitable for powder paints. They comprise a crystalline and an amorphous fraction which is determined by C13 NMR MAS relaxation measurements, the relaxation of the 13C cores being fitted as a biexponential relaxation according to the formula (II) and the degree of crystallinity c being in a range between 40 to 85%, and relaxation having a short average relaxation time T1S and a long average relaxation time T1l, and T1l being in a range of from 65 to 130 s. The effect pigments coated according to the invention have at least one endothermic peak with a maximum from a range of Tmax=100 to 150° C. and an enthalpy ΔH associated with said peak from a range of 15 J/g to 80 J/g in DSC at a feed speed of 5° C./min, the enthalpy being calculated relative to the amount of the binder. The binders are applied to the effect pigment by way of spontaneous precipitation.
