An ethyl acrylate/methyl methacrylate copolymer is an emulsion of a copolymer resin obtained by polymerizing ethyl acrylate and methyl methacrylate in water using polyoxyethylene nonylphenyl ether as an emulsifier and comprises a small amount of dimethylpolysiloxane. The amount of a solid content is about 30% by mass. Specifically, the ethyl acrylate/methyl methacrylate copolymer meets the standard of “ethyl acrylate/methyl methacrylate copolymer dispersion” in Japanese Pharmaceutical Excipients 2003 (JPE). As commercially available products, Eudragit NE30D (Degussa), Kollicoat EMM30D (BASF) and the like are used.
