Microcapsules are described, comprising one or more lipophilic substances as core material and a polymer as capsule shell, which are obtainable by radical polymerization of an oil-in-water emulsion containing DOLLAR A - 30 to 100 wt .-%, based on the total weight of the Monomers, one or more C¶1¶-C¶24¶ alkyl esters of acrylic and / or methacrylic acid (monomer I), DOLLAR A - 0 to 80 wt .-%, based on the total weight of the monomers, a bi- or polyfunctional monomers (Monomers II), which is insoluble or sparingly soluble in water and DOLLAR A - 0 to 40% by weight, based on the total weight of the monomers, other monomers (Monomers III), DOLLAR A the lipophilic substance and inorganic solid Particles with an average particle size of 45 to 1000 nm, a process for their preparation and their use in binders, textiles and plasterboard. |
