Abstract:
There is provided a cured-film formation composition that forms a cured film having excellent photoreaction efficiency and solvent resistance, and high adhesion, an orientation material for photo-alignment, and a retardation material formed with the orientation material. The cured-film formation composition comprises a component (A) that is a compound having a photo-aligning group and one substituent selected from a hydroxy group, a carboxy group, anvil an amino group, a component (B) that is a hydrophilic polymer having one or more substituents selected from to hydroxy group, a carboxy group, and an amino group; and a component (C) that is cross-linking agent that reacts with the component (A) and the component (B) and reacts at a temperature lower than a sublimation temperature of the component (A), wherein when the component (B) is an acrylic polymer, the cured-film formation composition further comprises a component (E) that is an adhesion enhancing component. The cross-linking agent of the component (C) may be more hydrophilic than the component (A). The orientation material is thrilled by thrilling a cured film with the cured-film formation composition and utilizing photo-alignment technique. The retardation material is obtained by applying a polymerizable liquid crystal on the orientation material and curing it.
