| abstract |
The present invention relates to a coating agent for forming a coating film which protects a lens, and, more particularly, to a fluorine-based coating agent for forming a coating film for lens protection on the surface of the lens using water dispersible polyurethane as a base material. The coating agent includes water-dispersed polyurethane containing fluorine-based polyol or includes a fluorine-based surfactant. The coating agent can form a film having good leveling action and releasability but having no adhesivity, and is environment-friendly. |
