摘要： Disclosed is a process for fabricating an artificial stone molded body by mixing an inorganic filler such as alumina with a resin binder and polymerizing and curing the mixture. A high-viscosity syrup formed by preliminarily polymerizing a polyol polyallyl carbonate with an ethylenically saturated monomer is used as the resin binder and is mixed with the inorganic filler. According to this process, the polymerization is completed in a short time and the internal stress in the molded body is moderated. The molded body fabricated according to this process is excellent in Barcol hardness, pencil hardness, taper abrasion, Sharpy impact strength, flexural strength, heat resistance and chemical resistance.

摘要： Disclosed is a transparent electromagnetic wave shielding material comprising a black electroconductive synthetic fiber gauze embedded in a molded synthetic resin body composed of diethylene glycol bisallyl carbonate. This gauze is preferentially located in the vicinity of the surface of the molded body, and the resin surface sinks in the portions of mesh openings of the gauze to impart a light scattering property to the surface.

摘要： A transparent resin substrate composed of a light-transmitting resin base sheet, and an underlying layer, a hard coat layer, and an antireflection coating formed sequentially on the base sheet. The antireflection coating includes a medium refractive index layer on the hard coat layer, and a low refractive index layer on the medium refractive index layer. The underlying layer is a cured product of a hexa- or higher functional urethane acrylate monomer. The hard coat layer is a cured product of a hard coat layer composition containing a polymerizable monomer containing 50% by mass or more of a tri- or lower functional urethane acrylate monomer, silica particles, a silane coupling agent, and a metal chelate compound. The medium refractive index layer is a cured product of a medium refractive index layer composition. The low refractive index layer is a particle-free cured product of a low refractive index layer composition.

摘要： A circumferentially light-emitting thermoplastic resin molded body which can be bent for use according to the type of optical ornaments or the shape of an object to be decorated and which allows the overall luminance of the emitted light to improve and restrains the luminescent color from being yellowed at the distal locations of such body with regard to the light source. The thermoplastic resin molded body has a core layer made from a thermoplastic elastomer; and a first clad layer made from a thermoplastic resin whose refractive index is smaller than the thermoplastic elastomer from which the core layer is made, in which a light diffusing agent is added to the thermoplastic elastomer from which the core layer is made and the thermoplastic resin from which the first clad layer is made respectively; and the total light transmittance of the first clad layer is defined as less than 70%.
