Estimating the term…
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.
A light control sheet capable of scattering an incident light of particular light angle, said sheet being produced by the process comprising preparing a film of a composition composed of at least two photopolymerizable components having different refractive indexes wherein the refractive indexes differ by at least 0.01, and irradiating on said film a light from a light source having a linear shape when viewed from a site of said film receiving irradiation from a particular direction to obtain a cured film.
A light control sheet capable of scattering a plurality of incident lights, each of particular incident angle, or an incident light of wide incident angle range, said sheet being produced by the process comprising preparing a film of a composition composed of at least two photopolymerizable components having different refractive indexes wherein the refractive indexes differ by at least 0.01, and irradiating simultaneously on the film a plurality of lights each of a particular direction from a plurality of light sources provided apart from each other to obtain a cured film.
A light control sheet having at least one portion capable of scattering a first incident light of particular light angle and at least one other portion capable of scattering a second incident light of particular incident angle different from that of the first incident light or capable of scattering any incident angle or capable of transmitting any incident angle, said sheet being produced by the process comprising a first step of preparing a film of a composition composed of at least two photopolymerizable components having different refractive indexes wherein the refractive indexes differ by at least 0.01, and irradiating a light from a light source having a linear shape when viewed from a site of the film from a particular direction on at least one of the divided film portions to obtain at least one film portion and a second step of curing at least one film portion other than said cured portion by (a) irradiation of a light from a direction and/or a light source different from that in the first step or by (b) a curing method different from that of the first step.
A process for producing a light control sheet capable of scattering an incident light of particular incident angle and transmitting an incident light of other than said particular incident angle without substantial scattering, which comprises:
A process for producing a light control sheet capable of scattering a plurality of incident lights each of a particular incident angle or an incident light of wide incident angle range and transmitting an incident light of other than said particular incident angle or angle range without substantial scattering, which comprises:
A process for producing a light control sheet having at least one portion capable of scattering a first incident light of a particular incident angle and transmitting an incident light of other than said particular incident angle without substantial scattering, and at least one other portion
A light control sheet capable of scattering an incident light of a particular incident angle and transmitting an incident light of other than said particular incident angle without substantial scattering, said sheet being produced according to a process comprising:
A light control sheet capable of scattering a plurality of incident lights each of a particular incident angle or an incident light of wide incident angle range and transmitting an incident light of other than said particular incident angle or angle range without substantial scattering, said sheet being produced according to a process comprising:
A light control sheet having at least one portion capable of scattering a first incident light of particular incident angle and transmitting an incident light of other than said particular incident angle without substantial scattering, and at least one other portion
A process for producing a light control sheet capable of scattering an incident light of particular incident angle and transmitting an incident light of other than said particular incident angle without substantial scattering, which comprises preparing a film of a composition composed of at least two photopolymerizable components having different refractive indexes and irradiating on said film a light of said particular incident angle to obtain a cured film.
A light control sheet comprising a film capable of scattering an incident light of a particular incident angle and transmitting an incident light of other than said particular incident angle without substantial scattering.
