Abstract

Provided are: a cured film-forming composition whereby a underlayer film for image formation formed from the composition exhibits high liquid repellency (lyophobicity) and lyophilic/liquid-repellent properties of the underlayer film can be easily changed even when exposed to a low amount of ultraviolet radiation; and a cured film obtained using the composition. The cured film-forming resin composition is characterized by containing: a polymer comprising a structural unit derived from a first monomer having the structure of formula (1) as component (A); a polymer other than component (A), which is a polymer in which the content of fluorine relative to the overall weight of the polymer is lower than in component (A), as component (B); a photoacid generator as component (C); and a solvent. (In the formula, Rdenotes hydrogen or a methyl group, and Rdenotes a fluorine-containing group able to be detached together with the oxygen atom bonded to R.)
