    摘要: One object of the present invention is to provide an emulsion composition comprising a silicone and an emulsion of a resin having a film forming property, which emulsion composition may provide a coating agent which effectively exhibits slidability of silicone on a substrate, while maintaining transparency. Another object of the present invention is to provide a laminate having a film made of the coating agent. The present invention provides an emulsion composition comprising (I) an emulsion of a resin having a film forming property in a solid content of 60 to 99.9 parts by mass and (II) an emulsion of a silicone-acrylic core-shell resin in solid content of 0.1 to 40 parts by mass, a total mass of the solid contents of components (I) and (II) being 100 parts by mass, wherein a core of the silicone-acrylic core-shell resin (II) is composed of an organopolysiloxane (A), a shell layer of the silicone-acrylic core-shell resin (II) is composed of a poly(meth)acrylate ester (B), a mass ratio of the organopolysiloxane (A) to the poly(meth)acrylate ester (B) is in a range of 40:60 to 95:5, and a covering ratio by the poly(meth)acrylate ester on a surface of the silicone-acrylic core-shell resin is at least 50%.

    摘要: An organosilicon compound includes a mixture of polymeric alkyl silicates. The polymeric alkyl silicates include at least 90% by weight a mixture of polymeric alkyl silicates of the formula (I) [SiO4/2]a [(RxO)SiO3/2]b [(RyO)SiO3/2]b′ [(RxO)2SiO2/2]c [(RxO)(RyO)SiO2/2]c′ [(RyO)2SiO2/2]c″ [(RxO)3SiO1/2]d [(RxO)2(RyO)SiO1/2]d′ [(RxO)(RyO)2SiO1/2]d″ [(RyO)3SiO1/2]d′″ [O1/2RzO1/2]e [O1/2RzOH]e′ [O1/2RzORX]e″ [O1/2RzORy*]e′″ (I). Polymeric alkyl silicates of a formula II are excluded.

    摘要: An organopolysiloxane composition is disclosed. The organopolysiloxane composition of includes at least (A) an organopolysiloxane expressed by an average unit formula, having a silicon-bonded hydroxyl group, (B) an organopolysiloxane expressed by an average unit formula, which is different from compound (A), and (C) a compound having at least two functional groups selected from ether bonds, ester bonds, and alkoxysilyl groups expressed by a formula, in one molecule. The amount of compound (A) is 2 to 70 mass % of the sum of component (A) and component (B). The amount of component (C) is an amount where the sum of functional groups in component (C) is 0.05 mols or more with regard to 1 mol of silicon-bonded hydroxyl groups in component (A). The composition has sufficient thixotropic properties, independent of inorganic powders such as fumed silica, precipitated silica, alumina, titanium oxide, and the like.
