Abstract
A composition includes a photoacid generator and a fluorine-containing epoxy resin that is a polymer of monomers that include an acrylic monomer (a) having a perfluoropolyether group having 9 or more carbon atoms and an acrylic monomer (b) having an epoxy group in a composition ratio such that a number of acrylic functional groups derived from the acrylic monomer (b) is larger than a number of acrylic functional groups derived from the acrylic monomer (a).
