The present invention relates to a photochromic mesoporous (mesoporous) fine particles and a method for producing the same, in particular after the photochromic dye and the polymer is reacted to produce a photochromic dye-grafted polymer, the photochromic dye is grafted The present invention relates to a method of preparing mesoporous fine particles by mixing an polymer with a surfactant to form an emulsion, then generating fine droplets from the emulsion, and drying and sol-gel reacting at a high temperature.n n n According to the present invention, by improving the dye leaching phenomenon that the photochromic dye leaks into the organic solvent in the conventional capsule, it can be applied not only to the aqueous ink, but also to the oil ink, paint, and coating, and at the same time to wrap the photochromic polymer with inorganic materials. Excellent blocking effect against free radicals or oxygen, excellent dispersibility, durability, coloration / discoloration rate, optical density, and storage stability. |
