The method of manufacturing the light control material for (meth) acryloyl group-containing polysiloxane resin, whereby a resulting light modulating material (meth) acryloyl group-containing polysiloxane resin, light modulating material and light control film using the same

A resin matrix material that is cured, light control particles contained in the resin matrix material of the light control material containing a light control suspension dispersed in a dispersion medium in a flowable state by irradiating an energy beam the manufacturing method of the light control material for (meth) acryloyl group-containing polysiloxane resin is intended to include comprising the following steps: (a) a (meth) acryloyl group-containing alkoxysilane compound, to be acid treated (meth) acryloyl group-containing silanol compound silanol conversion step for converting; and (b) the (meth) acryloyl group-containing silanol compound, and the silanol group-containing siloxane monomer and / or oligomer, the condensation materials including dehydration condensation, (meth) acryloyl group-containing polysiloxane dehydration condensation to obtain a resin. Thus, in the production of the light modulating material for (meth) acryloyl group-containing polysiloxane resin, it can be introduced from the condensation raw material (meth) acryloyl groups efficiently, polysiloxane resin.
