CONSTITUTION:The laminated safety glass consists of a penetration-resistant plastic sheet layer 5 having a photo-controlling functionality and inorg. glass layers 4 and 7 and this penetration-resistant plastic sheet layer 5 having a photo-controlling functionality has a gel cured layer 6 on the surface and the cured layer 6 is a cured product cured by irradiating a gel layer impregnated with a photo-polymerizable compsn. contg. a monomer and/or an oligomer which has a carbon-carbon double bond and can form a polymer having a refractive index being different from a refractive index of the sheet with a light from a linear light source by a specified angle. It is possible thereby to obtain the title laminated safety glass with the number of lamination being less than the laminated body wherein a penetration-resistant plastic is used, a thinner thickness, a simple manufacturing process and being inexpensive.

摘要： PURPOSE:To easily obtain the laminate of the light control plate which is joined to a resin sheet and has uniform optical characteristics by incorporating a plasticizer into the light control film, which is formed by irradiating a photopolymerizable compsn. with light to polymerize the compsn. CONSTITUTION:The plasticizer is incorporated into the inside of the light control film formed by irradiating the film-like body of the prescribed photopolymerizable compsn. with the prescribed light to polymerize the compsn. Namely, the plasticizer is incorporated into the light control film as well and, therefore, even if the plasticizer in the adhesive film tends to leach out, the infiltration of the plasticizer in the adhesive film into the light control film is obviated in the case of production of the laminate of the light control plate by using the adhesive film contg. the plasticizer. The deformation of the light control film to a corrugated plate shape is obviated and the laminate of the light control plate having the uniform optical characteristics is obtd.

摘要： PURPOSE:To stably produce the light diffracting plate having a large area by irradiat ing a film-like body consisting of a photopolymerizable compsn. with the light from a linear light source from a prescribed angle to polymerize the body, thereby forming a light control film having a prescribed film thickness. CONSTITUTION:A device for irradiation with UV rays is horizontally fixed with a bar-shaped mercury lamp 1 in the direction perpendicular to the progressing direction of a roll above the plane of a conveyor 3 and is further provided with a light shielding plate 2 above the plane of the conveyor 3. The installation position of the front end 5 of the light shielding plate 2 is held movable and adjustable in the progressing direction of the glass plate 4 coated with the resin compsn. The light shielding plate 2 is so set that the incident angle of the incident UV rays on the glass plate 4 attains about 0 deg. (alpha shown in Fig. approx.=0 deg.) at this time. The film-like body S on the glass plate 4 moving in the device by the conveyor 3 is irradiated with the UV rays at 0 deg. incident angle at all times. The film-like body S is polymerized and cured by the UV rays and the light diffracting plate laminated with the light control film S having 25 to 100mum film thickness on the glass plate 4 is obtd. The light diffracting plate having the large area of, for example, >=1m is stably produced extremely easily and inexpen sively in this way.
