摘要
The present invention relates to an organosilane compound having at least one silicon atom bearing at least one hydrolysable group, at least one non-hydrolysable group comprising a hydrophilic group, and at least one non-hydrolysable group comprising a hydrophobic group having at least one fluorine atom, said hydrophilic group and said hydrophobic group not both comprising, in the main chain, the same substituent of the silicon atom. The invention further relates to an optical article having a substrate coated with a precursor coating of an anti-fogging coating formed by depositing said organosilane compound on the surface of the optical article. The precursor of the anti-fogging coating, which also has anti-fouling properties, is converted into the actual anti-fogging coating by application of a surfactant film to the surface thereof.
