Retardation material forming resin composition, alignment material and a retardation member

【Task】 It has excellent photoreaction efficiency to provide a phase difference member forming resin composition for providing an alignment material capable of orienting the polymerizable liquid crystal with high sensitivity. A Wherein the heat-reactive sites containing resin [(A) component] with photoalignable group lead via a direct bond or a linking group, thermally curable phase materials forming resin composition, the alignment material characterized in that it is obtained by using the composition, and the phase difference member, characterized in that it is formed using the cured film obtained from the composition. .BACKGROUND
