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.

Abstract: To provide an antifouling article having an antifouling layer formed on the surface of an organic material using a fluorinated compound, wherein the antifouling article is excellent in antifouling properties and has durability such as abrasion resistance with respect to the antifouling properties. An antifouling article comprising: a substrate, at least a portion of the surface thereof being made of an organic material; a primer layer disposed on the surface made of the organic material; and an antifouling layer disposed on the primer layer; wherein: the primer layer is a layer formed by using a first silane compound which has a hydrolyzable silyl group, and a reactive organic group (a reactive organic group (A)) that is a group having a linking group and a reactive group, or a reactive group other than a hydrolyzable group; the absolute value of the difference between the SP value of the organic material and the SP value of the reactive organic group is from 0 to 3.
