Abstract
The invention relates to microcapsules having a particle size distribution that has at least two maxima, wherein the main maximum of the particle size lies in the range of 5 to 100 μm and wherein the volume assumed by the microcapsules that have a particle size less than ¼ of the particle size of the main maximum is greater than approximately 20% of the total volume of the microcapsules.
