Thin aluminum pigments having a narrow thickness distribution, method for producing same, and use of aluminum pigments
Abstract:
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.
