Document Type and Number:
WIPO Patent Application WO/2015/056741
Kind Code:
A1
Abstract:
[Problem] To provide a composition for forming a cured film that is suitable for forming a cured film that has excellent liquid crystal alignment properties and adhesion durability, to provide an alignment material, and to use the alignment material to provide a retardation material. [Solution] A composition for forming a cured film that contains: (A) at least one substance selected from among low molecular weight compounds that comprise a photoalignable group and at least one group selected from the group consisting of a hydroxy group, a carboxyl group, an amino group, an alkoxysilyl group, and the group that is represented by formula (2) (chemical formula (1)) and polymers that comprise a photoalignable group and a substituent that is selected from the group consisting of a hydroxy group, a carboxyl group, an amide group, an amino group, an alkoxysilyl group, and the group that is represented by formula (2); (B) a polymer that comprises at least one substituent selected from among a hydroxy group, a carboxyl group, an amino group, an alkoxysilyl group, and the group that is represented by formula (2); (C) a crosslinking agent; and (D) a low molecular weight compound that comprises at least one polymerizable group having a C=C double bond per molecule thereof and at least one N-alkoxymethyl group. The composition for forming a cured film is used to form a cured film, and photoalignment technology is used to form the alignment material. A polymerizable liquid crystal is applied on the alignment material and cured in order to obtain the retardation material.
