Title:
An optical article including temporary antifog covering provided with the improved endurance
Document Type and Number:
Japanese Patent JP5965321
Kind Code:
B2
Abstract:
The present invention relates to an optical article comprising a substrate provided with a coating comprising silanol groups on the surface thereof and, directly contacting this coating, an anti-fog coating precursor coating, said precursor coating having a static contact angle with water of more than 10° and of less than 50°, a thickness lower than or equal to 5 nm, and being obtained through the grafting of at least one organosilane compound having a polyoxyalkylene group comprising less than 80 carbon atoms and at least one silicon atom bearing at least one hydrolyzable group. The anti-fog coating precursor is converted into an actual anti-fog coating by applying on the surface thereof a film of a liquid solution comprising at least one surfactant. The anti-fog coating is immediately operational and provides long-lasting effects.
