PURPOSE:To provide a dyeing property to an inorganic glass lens, by providing an organic coating layer which can be dyed, on the surface of the inorganic glass lens. CONSTITUTION:To a partial hydrolyzate solution of tetraethoxysilane used as a material of an organic coating layer 2, a precondensate solution of a gram equivalent ratio 1:1 of hexakis(methoxymethyl)melamine and triethylene glycol, and a partial hydrolyzate of gamma-glycidoxypropyl triethoxysilane, an interfacial active agent FC-431 and stannous chloride are added, they are diluted by ''Ethyl Cellosolve '' are applied onto an inorganic glass body 1 by an immersing method, and are heated and hardened. As for a base material of the inorganic glass lens body 1, a flint compound F16, a barium compound BaSF and a lanthanum compound LaSk01 are used. |
