Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/189416
Kind Code:
A1
Abstract:
The present invention includes a polymer obtained from diamine components including at least one first diamine represented by general formula [I] and at least one second diamine having a side-chain structure selected from groups represented by general formulas [S1] to [S3], and an organic solvent. (In formula [I], Z1 represents an S atom or an O atom, and * represents a site for bonding to other groups; any of the hydrogen atoms in the benzene ring may be substituted with a monovalent organic group.) (In formula [S1], X1 and X2 each independently represent a single bond, –(CH2)a– (where a is an integer of 1-15), –CONH–, –NHCO–, –COs–NH–, –O–, –COO–, –OCO–, or –((CH2)a1–A1)m1–. Therein, each of the plurality of a1 independently represents an integer of 1-15, each of the plurality of A1 independently represents an oxygen atom –COO–, and m1 is 1-2. G1 and G2 each independently represent a divalent cyclic group selected from C6-12 divalent aromatic groups and C3-8 divalent alicyclic groups. Any of the hydrogen atoms in the cyclic group may be substituted with at least one selected from the group consisting of C1-3 alkyl groups, C1-3 alkoxyl groups, C1-3 fluorine-containing alkyl groups, C1-3 fluorine-containing alkoxyl groups, and fluorine atoms. m and n each independently represent an integer of 0-3, where the sum of m and n is 1-4. R1 represents a C1-20 alkyl, a C1-20 alkoxy, or a C2-20 alkoxyalkyl. Any of the hydrogens that form the R1 may be substituted with fluorine.) (In formula [S2], X3 represents a single bond, –CONH–, –NHCO–, –CON(CH3)–, –NH–, –O–, –CH2O–, –COO–, or –OCO. R2 represents a C1-20 alkyl or a C2-20 alkoxyalkyl; any of the hydrogens that form R2 may be substituted with fluorine.) (In formula [S3], X4 represents –CONH–, –NHCO–, –O–, –COO–, or –OCO–; R3 represents a structure having a steroid backbone.)
