A method of producing silica-based particles includes, when a dispersion liquid of composite oxide particles is prepared by simultaneously adding an aqueous silicate solution and/or an acidic silicic acid solution and an aqueous solution of an alkali-soluble inorganic compound in an alkali aqueous solution or in an alkali aqueous solution with seed particles dispersed therein, if required, the aqueous silicate solution and/or the acidic silicic acid solution and the aqueous solution of alkali-soluble inorganic compound are added so that the molar ratio of MO.sub.x/SiO.sub.2 are in a range from 0.01 to 2, herein MO.sub.x denoting an inorganic oxide other than silica and SiO.sub.2 denoting silica to prepare the dispersion liquid of composite oxide particles with an average diameter (D.sub.p1) in a range from 3 to 300 nm.

Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

Provided are a pressure-sensitive adhesive composition, a protective film, an optical device, and a display device. The pressure-sensitive adhesive composition may exhibit excellent storage stability, suitable low speed and high speed peel-off strengths after a crosslinking structure is formed, and have an excellent balance between them. Accordingly, the pressure-sensitive adhesive composition may exhibit an excellent protective effect when applied to a protective film, may be easily peeled in high speed peel-off and thus advantageous for a high speed process, and may exhibit an excellent antistatic property in the process.

An interlayer film for laminated glass that can improve a sound insulation property of an obtained laminated glass when the interlayer film for laminated glass is used for configuring the laminated glass is provided. The interlayer film for laminated glass according to the present invention includes a first layer and a second layer laminated on a first surface of the first layer. The first layer includes a polyvinyl acetate resin and a plasticizer.

The present invention is directed to curable film-forming compositions comprising: (a) a polymeric acrylic binder having reactive functional groups, wherein the polymeric acrylic binder is prepared from an ethylenically unsaturated, epoxy functional monomer that is reacted with benzoic acid; and (b) a curing agent containing functional groups that are reactive with reactive functional groups on the polymeric acrylic binder. Also provided is a multilayer coated substrate comprising: a substrate; a colored basecoat applied to at least a portion of a surface of the substrate; and a clearcoat applied to at least a portion of the basecoat, wherein the clearcoat is deposited from the curable film-forming composition described above.

The present disclosure relates to acrylic adhesive emulsions comprising a core-shell polymeric component comprising an inner core and an outer shell containing at least one pendent functional group; a polyfunctional component capable of reacting with at least one of the pendent functional groups on the outer shell; wherein the inner core is free of functional groups reactive with the pendent functional groups on the outer shell; and wherein the pH of the emulsion is 6.5 or less; and wherein the emulsion is a fast-setting, one part, aqueous, adhesive. Bonded articles made therefrom, and methods of bonding articles using these emulsions are also disclosed.

There is provided an optical film including an acrylic film, and a functional coating layer formed on at least one side of the acrylic film. The functional coating layer includes a water-dispersible resin and at least two kinds of fine particles having different average particle sizes.
