Abstract:
The present invention relates to microcapsule dispersions comprising microcapsules having a capsule core comprising water-soluble organic substances, and a capsule coating which essentially consists of polyurethane and/or polyurea, in a hydrophobic solvent which consists of 50 to 100% by weight of glycerol ester oils and 0 to 50% by weight of solvents miscible with glycerol ester oils, and to a process for their preparation.
