Abstract: PURPOSE: To continuously regenerate even in use and to guarantee high copying image quality over a long period by providing a specific iron oxide-containing surface coating on a steel spherical nucleus sulfuric acid-treated with a specific sulfuric acid aq. solution. CONSTITUTION: The sulfuric acid heated steel spherical nucleus obtained by heating the steel spherical nucleus with the sulfuric acid aq. solution having 10 to 10 mol/l acid concentration at the time of starting the treatment by using 5×10 to 25×10 mol sulfuric acid per 1m surface area of the steel spherical nucleus is used. The iron oxide-containing surface coating film expressed by formula I, which is obtained by oxidizing with the acid or oxidizing agent having the oxidation equivalent of 5×10 to 25×10 per 1m surface area and drying at 60-150 deg.C under

Abstract: Plateletlike pigments based on iron oxide and having a spinel structure of the composition: MnuAlvFe[3-(u+v)]-zO4-z, where u is from 0.01-0.09, v is from 0-0.3 and z is from 0-1. The pigments can be used for producing decorative coatings, in particular in paints, plastics, prints and cosmetics, for producing electromagnetic screens, as substrates for coatings and as pigments having magnetic properties.
