Disclosed is a light-transmitting electromagnetic-shielding laminate, which is characterized in that two or more layers including an electromagnetic-shielding layer are arranged in layers using a (meth)acrylate adhesive composition which contains a (meth)acrylate monomer, a (meth)acrylate oligomer and at least one member selected from the group consisting of acrylic amide derivatives, silane compounds and organophosphorus compounds. Also disclosed is a light-transmitting radio wave absorber which is characterized in that a resistive layer, a dielectric spacer and a reflective layer are arranged in layers using a (meth)acrylate adhesive composition which contains a (meth)acrylate monomer, a (meth)acrylate oligomer and at least one member selected from the group consisting of acrylic amide derivatives, silane compounds and organophosphorus compounds.

Light-transmitting electromagnetic-shielding laminate and method for producing the same, light-transmitting radio wave absorber, and adhesive composition

The present invention provides a method for manufacturing a laminate, comprising the steps of laminating two or more layers of polycarbonate resin film and/or sheet using a (meth)acrylate-based adhesive composition containing a (A) (meth)acrylate monomer, a (B) meth(acrylate) olygomer, an (C) acrylamide derivative, and a (D) silane compound and/or an (E) organophosphorus compound to form a laminate having a thickness of 0.1 mm to 30 mm; heating the laminate at 130&#xb0; C. to 185&#xb0; C. so that a temperature difference between a top surface and a bottom surface of the laminate is within 20&#xb0; C.; and bending the post-heating laminate into a curved shape having a radius of curvature of 10 mm or greater.

Bendable polycarbonate resin laminate, optically transparent electromagnetic wave shield laminate, and manufacturing method thereof

The present invention provides a light-transmitting electromagnetic wave-shielding material for use in displays or in-vehicle panels each having a polarizing plate or a retardation plate, wherein the light-transmitting electromagnetic wave-shielding material undergoes no generation of light interference fringes and is satisfactory in visibility even through sunglasses, goggles, glare-proof panels or glare-proof window materials having polarizing capability. By using unstretched light-transmitting organic polymer materials low in molecular orientation or small in molecular orientation unevenness as the base substrate of an electromagnetic wave-shielding layer, the light-transmitting electromagnetic wave-shielding material excellent in light interference fringe prevention capability can be obtained.
