To provide a cured-film-forming composition for providing an alignment material that has superior vertical alignment properties and is capable of vertically aligning polymerizable liquid crystals with high sensitivity even upon a resin film, and for providing a phase difference material that uses such an alignment material. A cured-film-forming composition, characterized by comprising: (A) a polymer obtained by reacting the carboxyl group of a compound having a carboxyl group and a vertical-alignment group with the epoxy group of a polymer having at least one epoxy group on a side chain or terminal thereof; and at least one compound selected from the group consisting of (B) a cross-linking agent and (C) an acid catalyst. An alignment material, characterized by being obtained using said composition. A phase difference material, characterized by being obtained using said composition.
