Abstract

The invention relates to a method for coating basic particle compounds with salt-forming acidic coating substances. Said method enables an especially homogeneous and thick coating to be created. The compound is suspended in a solution of the coating substance in a non-aqueous solvent in which the acidic coating substance dissolves well, but in which the alkaline salt thereof dissolves little. After a certain action time, said compound is removed. A peroxo compound, especially sodium percarbonate, is preferably used as the particle compound, and a film forming polymer which has free carboxyl groups and a softening temperature above 40 DEG C is preferably used as the coating substance. An organic liquid solvent boiling below 150 DEG C under normal pressure, preferably a monovalent alcohol comprising 1-4 C atoms, is suitable as the non-aqueous solvent.
