Abstract

A retardation material-forming resin composition for providing an orientation material that has high photoreaction efficiency and with which a polymerizable crystal can be aligned in a highly sensitive manner. A retardation material-forming resin composition being thermally curable wherein including a resin (component (A)) having a photo-aligning group to which a thermally reactive moiety is bonded directly or connected via a linking group; an orientation material obtained by use of the composition, and a retardation material formed by use of a cured film obtained from the composition.
