Fine particles in which pigments, fragrances, agricultural chemicals and the like are encapsulated in porous fine particles control the release rate of the substance to be supported, and the sustained release properties of sustained release porous fine particles or drugs in water Although fine particles could be produced, there is no fine particle with the function of preventing the release of the supported substance during storage and releasing the supported substance due to external factors such as heat, light, mechanical shock, etc. A function of quickly releasing the supported substance from the fine particles by applying a specific condition at this time was required. Porous fine particles in which a supported material is encapsulated in porous fine particles, and the surface of the supported material is covered with a curable compound or a polymer compound to hold the supported material and to release the supported material due to an external factor. And a method for producing the same, and a porous material in which a supported material and a compatibilized product of a curable compound or a polymer compound are encapsulated in porous fine particles to hold the supported material and release the supported material due to an external factor. It is a fine particle and its manufacturing method. [Selection] Figure 2 |
