Method of producing light control plate which induces scattering of light at different angles

摘要

A method of producing a light control plate for inducing scattering of light incident on a particular location of plate at a particular predetermined angle, at least some different locations on the plate requiring a different predetermined angle of incidence for scattering to occur. The method comprises (1) preparing an assembly comprising a film of a photopolymerizable composition and a light pervious body having a light-unpervious pattern arranged along the surface of the film, (2) irradiating the light-pervious body side of the assembly with light incident on the body at an angle within a predetermined range from a light source while moving the assembly continuously in the planar direction of the film thereby to polymerize at least part of the photopolymerizable film; and thereafter, (3) polymerizing the photopolymerizable composition of that portion of the film-like molded article which is covered with the light-impervious pattern of the light-pervious body by light irradiation or heating.
