The invention relates to a method for producing a hybrid particle, containing polymers and SiO2 particles, wherein a) in a first polymerization stage in an aqueous medium a water-insoluble phase, containing one or more monomers and colloidal SiO2 particles having a mean particle size of 1 to 150 nm, is polymerized, and b) in a second polymerization stage in an aqueous medium one or more monomers are polymerized in the presence of the polymer obtained in the first polymerization stage. |
