CURED FILM FORMING COMPOSITION, ALIGNMENT MATERIAL AND RETARDATION MATERIAL

WIPO Patent Application WO/2018/131682

A1

[Problem] To provide: an alignment material which has excellent vertical alignment properties and adhesiveness, and which is capable of vertically aligning polymerizable liquid crystals with high sensitivity even on a resin film; and a cured film forming composition for obtaining a retardation material that uses such an alignment material. [Solution] A cured film forming composition which contains (A) a polymer that has a vertical alignment group and a polymerizable group containing a C=C double bond and (B) a radical polymerization initiator, and which is characterized in that the vertical alignment group is represented by formula (1). (In formula [1], each of Y1 and Y2 represents a single bond or the like; Y3 represents a single bond or an alkylene group having 1-15 carbon atoms; Y4 represents a single bond, a divalent cyclic group or the like; Y5 represents a divalent cyclic group selected from among a benzene ring, cyclohexane rings and heterocyclic rings; n represents an integer of 0-4, and in cases where n is 2 or more, the Y5 moieties may be the same as or different from each other; and Y6 represents a hydrogen atom, an alkyl group having 1-18 carbon atoms, or the like.)
