Beschreibung
Zusammenfassung:	The present invention relates to microcapsule dispersions comprising microcapsules in a hydrophobic solvent, wherein the microcapsules have a capsule core, comprising at least one water-soluble organic substance in solution in a hydrophilic solvent, and a capsule shell, obtainable by a) interfacial polyaddition of at least one di-, oligo- and/or polyisocyanate with at least one reagent carrying at least one isocyanate-reactive group and b) subsequent aftertreatment of the primary product microcapsules with at least one compound selected from the group consisting of amines, alcohols and amino alcohols having a molecular weight of at least 150 g/mol and c) if appropriate, subsequent aftertreatment with at least one further aftertreatment reagent.
