Abstract
The present invention relates to a method for manufacturing a hard, water-resistant anti-fog coating, and particularly relates to a method for manufacturing a hard, water-resistant anti-fog coating on plastic material. In this method, an organic-inorganic hard adhesion layer and a hydrophilic anti-fog coating film are prepared for manufacturing a hard, water-resistant anti-fog coating. Both of the organic-inorganic hard adhesion layer and the hydrophilic anti-fog coating have C═C double bonds. Therefore, the organic-inorganic hard adhesion layer and the hydrophilic anti-fog coating are adhered to each other tightly. It brings high hardness, high water resistance and good anti-fog effect.
