Zusammenfassung:	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.
