PURPOSE:To make the durability and stability excellent by incorporating a photoreactive material in a part of a nuclear material to release the included nuclear material without modifying the wall of a capsule in the microcapsule consisting of a wall material forming the wall of the capsule and the nuclear material included in the inside of the wall of the capsule. CONSTITUTION:This microcapsule is constituted of the wall material forming the wall of the capsule and the nuclear material in the inside of the wall of the capsule, and the photoreactive material is incorporated at least in one part of the nuclear material. The photoreactive material is a polysilane having reaction unit expressed by formula (In the formula, each of F<1> and R<2> represents H, 1-24C (substituted) alkyl group, 6-24C (substituted) aryl group or 7-24C (substituted) aralkyl group). As a result, the releasing quantity of the included nuclear material is controlled by photoirradiation and the microcapsule excellent in durability and stability is obtained. |
