Abstract:
1. A method for manufacturing a hard, water-resistant anti-fog coating, comprising: forming an organic-inorganic hybrid hard adhesion layer on a base material wherein said organic-inorganic hybrid base material comprises a plurality of carbon-carbon double bonds (C═C), a first ultraviolet (UV) curing is performed in said step of forming an organic-inorganic hybrid hard adhesion layer on a base material but not all carbon-carbon double bonds (C═C) in said organic-inorganic hybrid hard adhesion layer reacts with the UV thereby there are some carbon-carbon double bonds (C═C) remained in said organic-inorganic hybrid hard adhesion layer without reacting with the UV; and forming a hydrophilic anti-fog coating film on said organic-inorganic hybrid hard adhesion layer wherein said hydrophilic anti-fog coating film comprises a plurality of carbon-carbon double bonds (C═C), a second UV curing is performed in said step of forming a hydrophilic anti-fog coating film on said organic-inorganic hybrid hard adhesion layer thereby the remained carbon-carbon double bonds (C═C) in said organic-inorganic hybrid hard adhesion layer are crosslinked with said carbon-carbon double bonds (C═C) in said hydrophilic anti-fog coating film for forming a cross-linked layer between said organic-inorganic hybrid hard adhesion layer and said hydrophilic anti-fog coating film which causes the hardness of the hydrophilic anti-fog coating film on said organic-inorganic hybrid hard adhesion layer to be 4H to 6H.
