Abstract
A method for producing a light-modulating film in which a light-modulating layer is sandwiched between two transparent resin substrates, the light-modulating layer being formed by use of a light-modulating material containing: a polymeric medium for forming a resin matrix; and a light-modulating suspension, includes the following steps: step (a) of applying the light-modulating material to one (a first transparent resin substrate: of the transparent resin substrates; step (b) of bonding the other transparent resin substrate (a second transparent resin substrate) onto the light-modulating material applied to the first transparent resin substrate; and step (c) of irradiating the light-modulating material sandwiched between the first transparent resin substrate and the second transparent resin substrate with an energy ray to cure the polymeric medium for forming the resin matrix contained in the light-modulating material, thereby forming the light-modulating layer to yield the light-modulating film.
