Abstract

A process for the preparation of a water soluble complex of bismuth and a polyacrylic acid, wherein a) the polyacrylic acid is dispersed in a solution of alkali or ammonia in a water-miscible organic solvent; b) a bismuth containing compound is added to the dispersion obtained according to a); and c) water and a water-miscible organic solvent are gradually added to the dispersion obtained according to b).
