Abstract: The seamless capsule of the invention is obtained by immersing in an aqueous fluid a two-layered seamless capsule comprising an inner layer comprising a suspension composition comprising a biocatalyst suspended in an oily substance and an outer layer comprising a shell composition comprising a water permeable substance. The seamless capsule of the invention, which has a pseudo three-layer structure of outer layer/oil layer/aqueous layer, is useful in that it is applicable to, for example, a bioreactor.

Abstract: This invention provides an electrodeposition paint comprising particles of at least one metallic compound selected from bismuth hydroxide, zirconium compound and tungsten compound, said particles of the metallic compound having an average particle diameter of 1-1,000 nm. The electrodeposition paint forms coating film excelling in corrosion resistance, finished appearance, paint stability and so on.
