Core-shell microcapsules comprising a hydrophobic core surrounded by a shell comprising a thermosetting resin comprising moieties derived from polyisocyanates, substantially unprotonated chitosan and another amine different from chitosan, characterized in that the substantially unprotonated chitosan is delivered in the solid, powder form to the locus of the encapsulation reaction. The core-shell microcapsules are provided in the form of a slurry comprising 10 to 50 wt % of microcapsules, based on the total weight of the slurry, and the shell of the microcapsules comprises from 0.1 to 20 wt % of moieties derived from chitosan, based on the total weight of the shell.
