Abstract
A method of producing a photocatalytic coating material which includes: the steps of coating the surface of a base material having hydrophobic substances on its surface with a photocatalytic coating material including at least (a) photocatalytic oxide particles, (b) a hydrophobic-resin emulsion, (c) water, and (d) silica particles, and hardening the coated material. The average sizes of the ingredient (a) and the ingredient (d) are smaller than that of the emulsified particles of the hydrophobic resin dispersed in the ingredient (b), ingredient (a) constitutes 1 to <5% by weight of the total solid matter of the coating material, ingredient (d) constitutes 1 to 90% by weight of a total solid matter of the coating material, and once the coating material is applied onto a base material, the photocatalytic oxide particles and the silica particles move upward and a coating film 1 μm to 1 mm thick is formed.
