Abstract:
1. A method of producing a photocatalytic composite, comprising 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) emulsified particles of hydrophobic-resin, (c) water, and (d) silica particles; and hardening the coated material at ordinary temperature; wherein the average particle sizes of the ingredient (a) and the ingredient (d) are smaller than that of the ingredient (b), ingredient (a) constitutes 1 to less than 5% by weight of the total solid matter of the coating material, ingredient (d) constitutes a total solid matter of the coating material in a range of 2.7%<(d)≦90% by weight, and a sum of the solid matter in the ingredients (a), (b), and (d) constitutes more than 30% by weight to less than 60% by weight of the entire coating composition.
