Abstract
The present invention relates to an in situ preparation of a redox initiated bimorphological aqueous dispersion of first polymer particles with protuberating phosphorus acid cores and second polymer particles without protuberating cores. The method provides a more efficient way of making compositions for pigmented coating formulations.
