The present invention relates to a particularly effective protective coating for metallic objects, the coating method, and the special applications thereof. The particularly high protective effect is achieved by the adaptation of the inorganic fraction and the organic polymer fraction of the coating to the specific surface of the object. Further adjustments of the coating can be used for further optimization, for example of the protection properties or other product properties.

There is disclosed a lamellar particle including an unconverted portion of the lamellar particle, wherein the unconverted portion includes a first metal, a converted portion of the lamellar particle disposed radially outward of at least one of a surface of the unconverted portion, wherein the converted portion includes a chemical compound of the first metal.

A solid composite material combining: an inorganic pigment in the form of discrete particles each comprising a colored core and a coating adapted to allow light to pass through and a matrix based on metalloid or metal oxide, said matrix being adapted to allow light to pass through.

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 h 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 h=100(h.sub.90h.sub.10)/h.sub.50, 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.
