Patent ID: 10570248

Abstract:
A cured-film formation composition that forms a cured film exhibiting excellent liquid-crystal orientation properties and excellent light transmission properties when the cured-film formation composition is used as an orientation material and a layer of a polymerizable liquid crystal is arranged thereon. A cured-film formation composition including a component (A) that is a compound obtained by reacting a cinnamic acid compound of Formula (1) below with a compound having at least one epoxy group in one molecule, wherein R1, R2, R3, R4, and R5 are each independently a substituent selected from a hydrogen atom, a halogen atom, a C1-6 alkyl, a C1-6 haloalkyl, a C1-6 alkoxy, a C1-6 haloalkoxy, cyano, and nitro; and a component (B) that is a cross-linking agent, an orientation material which is obtained from the composition, and a retardation material which is obtained from the composition.
