Procedure
Inventive Example 1 was essentially repeated, the dispersion being prepared via a miniemulsion process. For this purpose, 400 g of butyl acrylate, 390 g of methyl methacrylate, 200 g of methacryloyloxy-2-ethyl-linoleic ester and 10 g of methacrylic acid were emulsified with 20 g of sodium dodecyl sulphate. The methacryloyloxy-2-ethyl-linoleic ester was obtained by reaction of linoleic acid with hydroxyethyl methacrylate. As a hydrophobic agent, 4% of hexadecane were added additionally. The polymerization was initiated with 1% of AIBN at 75° C. The dispersion obtained had an rN5 value of 65 nm and a pH of 3.9. A coating formed from the dispersion showed a weight loss in MIBK of 13.6%, a water absorption after 24 h of 9.2% and a tensile strength of 2.8 MPa.
