摘要： PURPOSE:To provide the titled absorber with a heat ray absorption characteristic and a light transmission control characteristic in combination by forming the absorber of a light transmission control layer which selectively scatters only the incident light within a prescribed angle range and allows the transmission of the incident light of angles except said angle and a heat ray absorptive layer having the see-through characteristic and heat ray absorption characteristic. CONSTITUTION:This absorber consists of the light transmission control layer 1 which selectively scatters only the incident light within the prescribed angle range and allows the transmission of the incident light of angles except said angle and the heat ray absorptive layer 2 having the see-through characteristic and heat ray absorption characteristic. The light transmission control layer 1 is more preferably the light control film or sheet obtd. by curing resin compsns. consisting of plural compds. having a difference in the respective refractive indices and having >=1 polymerizable carbon-carbon double bonds in the molecule. Both the heat ray absorption function and the light transmission control function having dependency of the transmission of light on angles are thereby imparted to the above-mentioned absorber.

摘要： PURPOSE:To obtain uniform film quality to selectively scatter incident light of >=2 angle ranges by using a resin compsn. consisting of plural compds. which have a difference in the respective refractive indices and have >=1 polymerizable carbon-carbon double bonds in the molecule. CONSTITUTION:The light control plate selectively scatters the incident light of >=2 angle ranges to a plastic sheet. Namely, the resin compsn. consisting of the plural compds. which have the difference in the respective refractive indices and have >=1 polymerizable carbon-carbon double bonds in the molecule is maintained in a film state and UV rays are projected thereto from a 1st direction to cure the compsn. The resin compsn. is then maintained in a film shape on the cured matter obtd. in such a manner and the UV rays are projected thereto from the 2nd direction to cure the compsn. The 2nd stage is repeated at need. The light control plate is thus produced by the relatively simple method. The selective scattering by the angle of the transparent member and the transmission at only the specific angle are thereby attained.

摘要： PURPOSE:To obtain a light control plate which has plural overlapped shapes and parts different in light control direction and angle on a sheet of substrate by placing different photomasks on both faces of a film-like body consisting of a resin compsn. and projecting light for photopolymn. simultaneously thereon. CONSTITUTION:The film-like body 3 consisting of the resin compsn. contg. at least 2 kinds of polymerizable oligomers or monomers having a difference in refractive index is formed. The photomask 5 having a 1st shape is disposed between a 1st wire-shaped projection source 1 and the film-like body 3 and light is projected thereon from the projection source 1. The 2nd wire-shaped projection source 1 is simultaneously disposed to the film-like body 3 on the side opposite from the 1st projection source 1 and the photomask 5 having the 2nd shape is installed between the 2nd projection source and the film-like body, then the light is projected from the 2nd projection source 1. The parts which have the plural shapes and are different in the light control direction and angle are thereby superposedly formed on a sheet of the substrate.

摘要： PURPOSE: To improve decorative effects by the appearance or disappearance of characters or the like by a change in an observer's visual angle or the movement of a display by the action of a light control film having angular dependency. CONSTITUTION: The surface of a substrate made of glass, plastic, metal, paper, or the like is coated with a light control film or sheet capable of selectively scattering only incident light included within a prescribed angular range from a film and transmitting incident light with angles other than the prescribed angular range as the decoration of a display, a signboard or the like. An effect enabling an observer to observe the surface of the substrate transparently or opaquely in accordance with his (or her) observing angle is utilized. Consequently, a decorative display capable of captivating observer's eyes can be obtained.

摘要： PURPOSE:To easily obtain the titled plate constituted of a part having a high haze ratio and a part having a low haze ratio, by projecting an ultra violet ray to a composition contg. two or more kinds of monomers or oligomers which have a different refractive ratio respectively and are capable of photopolymerizing, through a mask. CONSTITUTION:The composition which contains at least two kinds of the photocopolymerizable monomers or oligomers and has the different refractive index, is applied on a substrate together with a photopolymerization initiator or is enclosed in a cell. The ultra violet ray is projected on the obtd. composition through the photomask at a 1st time to cure said composition, and then, the ultra violet ray is projected on the obtd. composition without the photomask at a 2nd time by a method different from that at the 1st time to cure an uncured part of said composition. Among the two different methods for projecting the ultra violet ray, one of them is the method for obtaining the part having the high haze ratio and another of them is the method for obtaining the part having the low haze ratio or no haze. Thus, the patterned plate which is constituted of the part having the high haze ratio and the part having the low haze ratio (or a transparent part), is easily obtd.

摘要： 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.
