[PROBLEMS] To combine a visible light photocatalyst and a microbial survival inhibitor into an aqueous composition, and survive sufficiently in a formed coating film, regardless of lighting conditions, even in indoor places with poor ultraviolet light, especially in medical institutions. To be able to exert a blocking action. An organic emulsification stabilizer / dispersant that improves the suspension state of photocatalyst fine particles is mixed with an aqueous composition containing at least one synthetic resin emulsion, a silicon compound, and a visible light responsive photocatalyst, and microorganisms survive. An inhibitor is appropriately added. |
