HOLLOW POROUS MICROCAPSULE, PHOTOCATALYST MICROCAPSULE, PHOTOCATALYST MICROCAPSULE FOR AMMONIA DECOMPOSITION, PHOTOCATALYST MICROCAPSULE-CONTAINING COATING COMPOSITION, PHOTOCATALYST MICROCAPSULE-CONTAINING COATING COMPOSITION FOR ELECTROSTATIC COATING AND PHOTOCATALYST MICROCAPSULE-CONTAINING FILM STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a microcapsule comprising a component which contains an oxide including specified elements, and to provide a photocatalyst microcapsule or else which includes a photocatalyst component in the microcapsule.

SOLUTION: The microcapsule comprises a component which contains an oxide including iron element and silicone element. The photocatalyst microcapsule and the photocatalyst microcapsule for ammonia decomposition includes a photocatalyst component such as titanium dioxide fine particles. The photocatalyst microcapsule-containing coating composition and the photocatalyst microcapsule-containing coating composition for electrostatic coating contains the photocatalyst microcapsule or the photocatalyst microcapsule for ammonia decomposition and binder such as acrylic emulsion. The photocatalyst microcapsule-containing film structure is obtained by applying the photocatalyst microcapsule-containing coating composition or the photocatalyst microcapsule-containing coating composition for electrostatic coating on a base material, and one part of the photocatalyst capsule is exposed on the surface of a formed film.
