    摘要： Suggested is the use of microcapsules having an average diameter of 0.1 to 25 µm, obtainable in that
    (a1) an emulsion is prepared comprising actives and optionally oil components and/or emulsifiers,
    (a2) said composition is treated with aqueous solutions of anionic polymers to form a matrix,
    (a3) said matrix is brought into contact with aqueous solutions of cationic polymers to form a capsule and optionally
    (a4) said capsules being separated off from the aqueous phase,

    or
    (b1) an emulsion is prepared comprising actives and optionally oil components and/or emulsifiers,
    (b2) said composition is treated with aqueous solutions of cationic polymers to form a matrix,
    (b3) said matrix is brought into contact with aqueous solutions of anionic polymers to form a capsule and optionally
    (b4) said capsules being separated off from the aqueous phase,

    for making paints and lacquers.

    摘要： Suggested are hydrophobically modified alkali swellable emulsions, comprising polymers consisting of the following monomers:
    (a) 20 to 55 % b.w. acrylic and/or methacrylic acid,
    (b) 40 to 80 % b.w. C 1 -C 4 alkyl (meth)acrylates,
    (c) 1 to 40 % b.w. of a maleic acid ester according to general formula (I)

             R 2 OOC-CH=CH-COO(CH 2 CH 2 O) n R 1 (I)

    in which R 1 stands for a linear or branched alkyl, aryl or alkaryl radical having 8 to 22 carbon atoms, R 2 stands for hydrogen or (CH 2 CH 2 O) n R 1 and n means a number between 2 and 150,
    (d) 0 to 15 % b.w. of aralphatic compounds having at least one double bond in the aliphatic side chain, and
    (e) 0 to 1 % b.w. polyethylenic unsaturated cross-linking monomer,

    calculated on the total composition of the polymers and under the condition that compounds (a) to (e) add up to 100 % b.w.
