PROBLEM TO BE SOLVED: To apply a heat insulating paint to the surface of a building is often performed. In addition, if the surface of the building becomes dirty, the reflectance of light decreases, it becomes easier to absorb heat, and the heat insulation effect is reduced. Therefore, the present invention provides a paint that serves the purpose of preventing dirt and heat insulation, can greatly reduce the decomposition of the resin, and can be easily applied. [Solution] Organic hollow balloon A with photocatalyst fine particles fixed to the surface by heat fusion, organic hollow balloon B with fine particles other than photocatalyst fixed to the surface in the same manner, organic resin, colloidal silica, and water The organic hollow balloon B has a specific gravity greater than that of the organic hollow balloon A.
