    Abstract: A finely divided polymer dispersion which is particularly suitable for the strengthening priming of paint substrates is prepared by polymerising a mixture of unsaturated monomers. The monomers used are a) from 20 to 80% by weight of styrene and/or methyl methacrylate as hardening component, b) from 20 to 80% by weight of an ester of acrylic acid and/or of methacrylic acid as softening (plasticising) component, c) from 0.1 to 5% by weight of an amide of an alpha , beta -unsaturated carboxylic acid, and d) from 0.1 to 5% by weight of an alpha , beta -unsaturated monocarboxylic acid. The polymerisation is carried out under the conditions given in Patent Claim 1. The polymers obtained have a particle size of from 0.01 to 0.06 mu m.
