Abstract
A light control sheet capable of scattering an incident light of particular incident angle is produced by a method composed of preparing a film of a composition containing at least two photopolymerizable components having different refractive indexes, irradiating on the film a light from a particular direction, and obtaining a cured film of the light control sheet product. Such other light control sheets as capable of scattering a plurality of incident lights each of particular incident angle are obtained by modification of the above-mentioned method.
