Patent ID: 8817360

Claim:
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, the method comprising the steps of: the step (a) of applying the light-modulating material to one (a first transparent resin substrate) of the transparent resin substrates; the 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 to obtain a lamination; and the 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, wherein the step b) is performed before the step c), and wherein the lamination is pressed from either the first transparent resin substrate side thereof or from the second transparent resin substrate side thereof, or the lamination is pressed from both of the first transparent resin substrate side thereof and the second transparent resin substrate side thereof in the step (b).
