Light control film using the light control particles obtained by the production method and the production method of the light control particles

The method of manufacturing a light control particles, resin matrix and formed from a polymeric medium which is cured by irradiating an energy beam, a dispersion medium, a light control particles dispersed in a flowable state into the dispersing medium, the light control suspension with a method for manufacturing a light control particles that can be used for the light control material containing, (a) elemental molecular iodine, (B) an alkaline earth metal iodide, (C) coexist in the step of granulating by mixing a heterocyclic compound in a medium, wherein (a), (B) and (C) total 100 parts by mass 110 parts by mass of methanol or 50 parts by weight with respect to part of the then, to react. Thus, in order to obtain good light control particles having an optimum particle size and shape as the light modulating material efficiency, the granulation step of the manufacturing method of the light control particles, to reduce the influence of moisture, a good and reproducible It can provide a method for producing a light control particles.
