Patent ID: RE38752

Claim:
A method of manufacturing a fluorocarbon-based polymer coating film comprising the steps of: contacting a substrate having a surface containing hydroxyl groups with a non-aqueous solvent comprising a material comprising chlorosilyl groups; coating the substrate surface with either ( 1 ) a non-aqueous solvent comprising a compound comprising a fluorocarbon group and a chlorosilyl group or ( 2 ) a solvent comprising (a) a compound comprising a fluorocarbon group, and an alkoxysilane group or (b) a compound of the following formula: CF 3 —(CF 2 ) n —(R) m —SiY q (OA) 3—q where n represents 0 or an integer; R represents an alkyl group or a hydrocarbon substituted group containing C=C or C≡C, a silicon atom or an oxygen atom; m represents 0 or 1 ; Y represents a hydrogen atom, an alkyl group, an alkoxy group, a fluorine-containing alkoxy group or a fluorine-containing alkyl group; A represents a hydrogen atom; q represents 0 , 1 or 2 ; and baking the substrate after said contacting step and coating step.
