Abstract
PURPOSE:To obtain a desired light control plate without hindering the curing a resin compsn. by installing a UV resistant transparent layer or substrate on the surface opposite to the surface to be irradiated with UV rays without adding a UV absorbent, etc., to the resin compsn. CONSTITUTION:The resin compsn. 3 consisting of a mixture composed of photopolymerizable monomers or oligomers having a difference in respective refractive indices is held or coated on the colorless or chromatic UV resistant transparent layer or substrate 2 to form a film-like body. Light is projected by a UV lamp 1 to the photopolymerizable resin compsn. 3 from the surface opposite to the surface on which the UV resistant transparent layer or substrate 2 is installed to cure said resin compsn. Since there is no need for adding the UV absorbent, etc., to said compsn., the curing is not hindered. The light control plate which selectively scatters only the incident light from the range of the prescribed angle with a film and transmits the incident light of angles except said angle is thereby obtd.
