[Problem] to provide a cured film-forming composition optimal in formation of a cured film having excellent liquid crystal alignment properties, to provide an alignment material, and to provide a phase difference material using said alignment material. [Solution] This cured film-forming composition contains: (A) one or multiple types of cinnamic acid esters having a group represented by formula (1) (in the formula, R1 and R2 independently represent a hydrogen atom or an alkyl group, R3 represents an alkyl group, etc., and X1 represents an optionally substituted phenylene group); (B) at least one type of polymer selected from the group consisting of (B-1) to (B-3) below (B-1): polymers having at least two of at least one group selected from the group consisting of a hydroxy group, a carboxyl group, an amide group, an amino group, an alkoxysilyl group and a group represented by formula (2) (in the formula, R62 represents an alkyl group, and alkoxy group, or a phenyl group.) (B-2): polymers which can self-crosslink and which can thermally react with at least one group selected from the group consisting of a hydroxy group, a carboxyl group, an amide group, an amino group, an alkoxysilyl group and a group represented by formula (2) (B-3): a melamine-formaldehyde resin; and (C) a cross-linking agent (may be the same as the (B-2) component when the (B) component is (B-2) above). Also provided is a cured film, an alignment material and a phase difference material. |
