Patent Searching and Data


Title:
LIQUID-CRYSTAL MATERIAL, LIQUID-CRYSTAL FILM, METHOD FOR PRODUCING SAME, SENSOR, AND OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/189444
Kind Code:
A1
Abstract:
A liquid-crystal material containing a cellulose derivative having a molecular structure represented by general formula (1A). In general formula (1A), X11, X12, and X13 each independently represent a single bond, an alkylene group, -(R14-O)h-, or-C(=O)-R15-; R11, R12, and R13 each independently represent a hydrogen atom, a group having an unsaturated double bond, or a hydrophobic group; R14 and R15 each independently represent an alkylene group; h represents an integer of 1-10; and n11 represents an integer of 2-800. However, at least one of R11, R12, and R13 represents a group having an unsaturated double bond represented by general formula (3C) and/or a C5-20 linear or branched acyl group.
