ABSTRACT:
A microcapsule which includes a polymer as a capsule wall of the microcapsule, in which the polymer is obtained by polymerizing a dendritic branching molecule having a hydroxyl group in a terminal thereof, an isocyanate compound, and a compound having two or more active hydrogen atoms in a molecule thereof. A process for manufacturing a microcapsule includes the step of polymerizing an isocyanate compound, a dendritic branching molecule having a hydroxyl group in a terminal thereof, and a compound having two or more active hydrogen atoms in a molecule thereof, so as to form a capsule wall of the microcapsule.
