摘要:
A laminated glass is composed of glass plates, between which a thermosetting resin composed of a copolymer of ethylene-vinyl acetate, a hydrocarbon resin and an organic peroxide is inserted and cured to intergrate them. An organic resin film is inserted between layers of the thermosetting resin. The thermosetting resin contains dibenzylidene sorbitol and/or tribenzylidene sorbitol. The thermosetting resin contains one or more kinds of silane coupling agent selected from the group consisting of acryloxy group containing compound, methacryloxy group containing compound and aryl group containing compound, and an absorber for ultra violet ray are contained. Preparation of the thermosetting resin is carried out by previously mixing a part of the copolymer of ethylene-vinyl acetate with the hydrocarbon resin to obtain a mixture, mixing residual amount of the copolymer of ethylene-vinyl acetate into the mixture, and adding the organic peroxide to mix.

A sandwich glass is disclosed containing a thermoset resin layer interposed between glass plates, wherein the thermoset resin layer, prior to thermosetting, contains an uncured resin composition containing:(a) an organic peroxide,(b) an ethylene-vinyl acetate copolymer, and(c) at least one compound selected from the groupconsisting of at least one acryloxy or methacryloxy group-containing compound and a hydrocarbon resin having a ratio of hydrogenation .gtoreq.91%;wherein the at least one acryloxy or methacryloxy group-containing compound is selected from the group consisting of 1-methyl-1,3-dimethacryloxypropane, 2,2-dimethyl-1,3-diacryloxypropane, 2,2-dimethyl-1,3-dimethacryloxypropane, 2-hydroxy-1-acryloxy-3-methacryloxypropane, 2-hydroxy-1,3-dimethacryloxypropane, 1-hydroxy-2-methyl-1,3-diacryloxypropane and 1-hydroxy-2-methyl-1,3-dimethacryloxypropane and the ethylene-vinyl acetate copolymer contains vinyl acetate in an amount of 10-50% by weight. The sandwich glass of the present invention results in an improved resistance to yellowing and less perspective distortion.

摘要:
To manufacture an electromagnetic-wave shielding and light transmitting plate having a conductive pattern of which line width is narrow and open area ratio is high, a resin pattern 2 is printed on a transparent film 1 having a low affinity for a plated layer by using a resin having a high affinity for the plated layer. Then, a conductive material layer is formed by electroless plating on the resin pattern 2 of the film 1, thereby forming the conductive pattern 3. After that, the blackening treatment is conducted, thereby obtaining the electromagnetic-wave shielding and light transmitting plate.
摘要:
A light transmission tube includes a tubular clad and a core section having a higher refractive index than that of the tubular clad. A belt-like reflecting layer is formed between the tubular clad and the core section, extending in the longitudinal direction of the tubular clad, in a manner such that a light passing through the core section is reflected and scatterred by the reflecting layer and then emitted from an outer surface area of the tubular clad, which outer surface area is located opposite to one side of the tubular clad where the reflecting layer has been formed. Further, the reflecting layer may be so formed that a light is allowed to be emitted in a plurality of directions. Moreover, the belt-like reflecting layer may be formed into a spiral configuration. The width of the belt-like reflecting layer may be changed in the longitudinal direction of the light transmission tube. The tubular clad is allowed to have a non-circular cross section. The clad formation material may contain an ultraviolet light shielding material or an ultraviolet light absorbing material.
摘要:
A method of making an optical transmission tube comprises having a tubular clad and a core covered with the tube and having a refractive index higher than the clad. The core has light-scattering particles uniformly dispersed in or throughout the core, so that light passing through the core is reflected and scattered at individual scattering particles to permit the light to be emitted from outer surfaces of the clad.

To manufacture an electromagnetic-wave shielding and light transmitting plate having a conductive pattern of which line width is narrow and open area ratio is high, a negative pattern 2 composed of dots is printed on a transparent film 1 having a high affinity for a plated layer of a conductive material by using a transparent resin having a low affinity for the plated layer and a backside coating layer 3 is formed by printing a transparent resin on the entire back surface of the transparent film 1. Then, a conductive material layer is formed by electroless plating to cover the film exposed surface not covered by the negative pattern 2 of the film 1, thereby forming the conductive pattern 4. After that, the blackening treatment is conducted, thereby obtaining the electromagnetic-wave shielding and light transmitting plate.
摘要:
A display panel such as a plasma display panel is provided in which an electromagnetic-wave shielding material is integrated whereby electromagnetic-wave shielding efficiency is imparted to a display panel itself. A transparent film 2 having a conductive pattern 3 is bonded to a front surface of a plasma display panel 20 by transparent adhesives 4A. The conductive pattern 3 is in a mesh form having a line width of 50 &mgr;m or less and an open area ratio of 75% or more and is formed by vapor plating or liquid phase plating. To form a conductive pattern, dots 12 are printed on a transparent film 11 by using material which is soluble in solvent such as water. Then, a conductive material layer 13 is formed so as to cover over all the dots 12 and exposed portions of the transparent film 11. The film 11 is cleaned by the solvent such as water. By the cleaning process, the soluble dots 12 are dissolved and the conductive material on the dots 13 are also removed from the film 11. Accordingly, conductive material formed on the exposed portions are left uncovered by the dots so as to form a conductive pattern 14. In this manner, the conductive pattern 14 plated on areas of the film 11 other than the dots 12 is formed.
