Patent ID: 8497315

Claim:
A process for the preparation of an aqueous dispersion which is stabilized with a water-insoluble stabilizing colloid, the process comprising: preparing the water-insoluble stabilizing colloid by means of a radical polymerization in water of about 3 to 30 weight % of at least one olefinically unsaturated monomer containing at least one of a sulfate group and a sulfonate group, about 50 to 95 weight % of at least one olefinically unsaturated monomer having a water solubility at 20° C. of less than 50 g/l, and up to 20 weight % of at least one olefinically unsaturated monomer having a water solubility at 20° C. of more than 50 g/l, wherein the weight % is based on the total amount of monomer used for preparing the water-insoluble stabilizing colloid; and adding at least one further olefinically unsaturated monomer and at least one initiator, such that by means of a radical polymerization of the at least one further olefinically unsaturated monomer, the aqueous dispersion is obtained.
