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.

A method for producing silica-coated spherical silicone elastomer particles which includes a step in which a tetraalkoxysilane (E) is added to a liquid comprising spherical silicone elastomer particles (A), an alkaline substance (B), one or more ingredients (C) selected from among cationic surfactants and cationic water-soluble polymers, and water (D), and the tetraalkoxysilane is hydrolyzed and condensed to thereby coat the surfaces of the spherical silicone elastomer particles with silica.

The present disclosure provides a high temperature, flame resistant and flexible coating composition based on alkali silicate and fluoropolymers. The coating can be used to bond a surface of a non-woven mat and seal the edges. The coating composition can be applied using a coating method on the surface and the edges of, for example, an inorganic fiber based non-woven mat.
