<p>A photocatalytic hydrophilic coating material which can be easily applied in situ to a surface of a member to impart a high degree of hydrophilicity while attaining high transparency and which maintains the hydrophilicity. The coating material comprises water, a photocatalytic metal oxide (A), an alkyl silicate (B), and an alkali silicate (C). The proportion of the ingredient (A) to the ingredient (B) on a solid basis is that the TiO2/SiO2 ratio is from 2/8 to 8/2. The content of the alkali silicate is 10 to 40 wt.% based on all the solid ingredients.</p> |
