Abstract:
The invention consists of a process for preparation of self-binding pigmentary particles, dry or in aqueous suspension or dispersion, using in a particular stage of the process a reverse emulsion formed from a dispersion in an oily phase of water particles and of at least one polymer of acrylamide with an acrylic monomer.
