Abstract (en)

[origin: US4388403A] Dispersions of hydrophobic substances in water are prepared by dissolving the hydrophobic substance together with an ionomeric polyaddition or condensation product in an organic, water-miscible solvent or a mixture of such a solvent with water, diluting the solution with water and removing the organic solvent. The dispersions are excellently suitable for the preparation of photographic recording materials.
