Abstract: A process for producing a light control plate which selectively scatters incident light of a specific angle, which comprises:(1) bringing at least one photopolymerizable compound of a photopolymerizable monomer and a photopolymerizable oligomer into contact with a transparent plastic film or sheet, each of the monomer and the oligomer having a polymerizable carbon-carbon double bond and being capable of forming a polymer having a refractive index different from a refractive index of said transparent plastic film or sheet, to allow said photopolymerizable compound to infiltrate into said transparent film or sheet through a surface of said transparent film or sheet, thereby forming a swollen surface layer, and(2) irradiating the swollen surface layer with light from a linear light source at a predetermined angle to cure said swollen surface surface layer.

Abstract: A process for producing a light control plate, which comprises(1) preparing an assembly composed of a film of a photopolymerizing composition and a light pervious body having a light scattering pervious pattern arranged along the surface of the film and (2) irradiating light to the assembly from that side of the assembly on which the light pervious body exists, thereby to polymerize the photopolymerizable composition of the film and to form a light control plate having a light pervious region through which light advances straightforwardly defined by the light scattering pervious pattern.

Abstract: A method of producing a light control plate which induces scattering of light at different angles of incidence for different places. The method comprises (1) preparing an assembly comprising a film of a photo-polymerizable composition and a light-pervious body having a light-impervious pattern arranged along the surface of the film, (2) irradiating light limitedly to the assembly from that side where the light-pervious body at a limited angle while moving the assembly continuously in the planar direction of the film thereby to polymerize at least part of the photopolymerizable film, the light being emitted from a first linear light source whose long axis is positioned in a direction crossing the moving direction of the assembly; 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.
