Abstract
To provide the method of forming the thin coating film of fluorine-containing polymer having heat resistance and non-sticking property by adhering directly to a substrate without lowering characteristics such as reflection and light transmission which the substrate has. The thin coating film is a film which comprises a continuous layer of fluorine-containing polymer formed by adhering directly to the substrate and has a thickness of less than 3 μm, wherein the fluorine-containing polymer in the coating film has a hydrophilic functional group and a crystalline melting point of not less than 200° C.
Claims14
A thin coating film on a substrate, said thin coating film having a thickness of not more than 0.5 μm and consisting essentially of a continuous layer of fluorine-containing polymer formed by adhering directly to a substrate, said fluorine-containing polymer in the coating film having a hydrophilic functional group and a crystalline melting point of said fluorine-containing polymer being not less than 200° C.
A thin coating film on a substrate, said thin coating film having a total thickness of less than 3 μm and comprising at least two layers of a layer of (A) a fluorine-containing polymer having hydrophilic functional groups and a layer of (B) a fluorine-containing polymer having no functional group, where the layer of (A) is between the substrate and the layer of (B).
