Abstract: A modifier for resin has an average particle size of 20 ?m or more, wherein particles having an average particle size of 10 ?m or less account for less than 30% by mass of the modifier, and particles having an average particle size of 10 ?m or less account for 30% by mass or more of the modifier after irradiating the modifier with ultrasonic wave of 40 W for 5 minutes. Also a resin composition comprises 1 to 40% by mass of the modifier for resin and 99 to 60% by mass (the total amount of both components is 100% by mass) of a thermoplastic resin or a curable resin, and a molded article is produced by molding the same.

Abstract: A coating comprising a polymer (I)-containing coating component and colloidal silica (II) of 60 nm or less average particle diameter, wherein 0.5 to 20 parts by mass, in terms of solid content, of colloidal silica (II) is contained per 100 parts by mass of polymer (I) and wherein the area of colloidal silica exposed from the surface of the coating occupies 35% or more based on the coating surface. This coating exhibits excellent antifouling performance and excels in transparency, weather resistance, water resistance, and elongation degree.

Abstract: A particulate vinyl polymer is provided. At least 95 wt. % of its particles have a minor axis A and a major axis B, which are in a relationship of 1.ltoreq.B/A.ltoreq.1.5 and individually range from 30 .mu.m to 400 .mu.m. The polymer has an acid value of from 30 to 150 mgKOH/g. This particulate vinyl polymer is excellent in work-ability such as the solubility in aqueous medium, and is useful as a raw material for water-base coating compositions having superb dispersion of a pigment and excellent waterproofness.
