Composition containing fluorinated polymer and method for producing fluorinated polymer film-provided substrate

Abstract

To provide a composition which comprises a fluorinated polymer having an alicyclic ring, from which a film having excellent in-plane uniformity and small surface roughness can be formed by an electrospraying apparatus, and a method for producing a film-provided substrate using the composition. A composition comprising a fluorinated polymer having an alicyclic ring and a solvent, wherein the solvent contains at least one high boiling point solvent having a boiling point of at least 150° C., and the solvent has a dielectric constant of at least 5. And, a method for producing a film-provided substrate, which comprises applying the composition to a substrate by an electrospraying apparatus to form a film containing the fluorinated polymer.
