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%.
