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.
一种微胶囊,包括作为微胶囊囊壁的聚合物,其中聚合物是通过聚合在其末端具有羟基的树枝状分支分子、异氰酸酯化合物和在其分子中具有两个或两个以上活性氢原子的化合物而获得的。一种制造微胶囊的工艺包括以下步骤:聚合异氰酸酯化合物、末端带有羟基的树枝状分支分子和分子中含有两个或两个以上活泼氢原子的化合物,以形成微胶囊的囊壁。
