Antifogging products, inorganic hydrophilic hard coating forming material and method for mfg. anti-fog lens

An antifogging product comprises an inorganic hydrophilic hard layer having a great number of nano-size concave portions with an average depth of 10 nm to 10 mu m from the surface, and being filled up a surfactant in the concave portions so as to flow out continuously. The hard layer has a high mech...

Beschreibung
Zusammenfassung:	An antifogging product comprises an inorganic hydrophilic hard layer having a great number of nano-size concave portions with an average depth of 10 nm to 10 mu m from the surface, and being filled up a surfactant in the concave portions so as to flow out continuously. The hard layer has a high mechanical strength and its antifogging effect sustainable for long periods of time, and is formed on a transparent base material of a lens, a plastic plate or the like at a low temperature near room temperature. Therefore, the antifogging product are extremely useful not only in eye-glass lenses but in many applications, including goggles and optical windows.
