[과제] 배향재로서 사용되어, 그 위에 중합성 액정의 층이 배치되었을 때에, 우수한 액정배향성과 광투과성을 나타내는 경화막을 형성하는 경화막 형성 조성물을 제공한다. [해결수단] (A)에폭시기를 갖는 모노머와 하기 식(1)로 표시되는 계피산 유도체와의 반응생성물인 모노머를 이용하여 얻어지는 중합체, 그리고 (B)가교제를 함유하는 경화막 형성 조성물, 해당 조성물을 이용하여 얻어지는 것을 특징으로 하는 배향재, 해당 조성물을 이용하여 얻어지는 것을 특징으로 하는 위상차재.(식(1) 중, A과 A는 수소원자 또는 메틸기를 나타내고, R은 수소원자, 할로겐원자 등을 나타내고, R는 2가의 방향족기, 2가의 지환족기, 2가의 복소환식기 또는 2가의 축합환식기이고, R은 단결합, 산소원자 등이고, R~R은 각각 독립적으로 수소원자, 할로겐원자 등이고, n은 0~3의 정수이다.) [Problem] To provide a cured film-forming composition for forming a cured film which exhibits excellent liquid crystal alignment properties and light transmissivity when used as an alignment material with a layer of a polymerizable liquid crystal disposed thereupon. [Solution] A cured film-forming composition containing (A) a polymer obtained using a monomer, the monomer being a reaction product of a monomer having an epoxy group and a cinnamic acid derivative represented by formula (1), and (B) a crosslinking agent; an alignment material characterized by being obtained using the composition; and a phase difference material characterized by being obtained using the composition. (In formula (1): A1 and A2 represent a hydrogen atom or a methyl group; R1 represents a hydrogen atom, a halogen atom, or the like; R2 is a divalent aromatic group, a divalent alicyclic group, a divalent heterocyclic group, or a divalent fused ring group; R3 is a single bond, an oxygen atom, or the like; R4 to R7 are each independently a hydrogen atom, a halogen atom, or the like; and n is an integer from 0 to 3.)
