Abstract: A composition for forming a hydrophilic coating includes an organic binder having an average particle size from about 1 to about 100 nm and an inorganic binder having an average particle size from about 1 to about 40 nm. The composition further includes an inorganic photocatalyst that catalyzes an oxidation-reduction reaction. Characteristically, the photocatalyst includes a photocatalytic metal oxide having an average particle size from about 1 to about 50 nm. Advantageously, coatings formed from the composition have improved stain resistance, low contact angle, and resistance to dirt adherence, while maintaining a clear optical character.
