Title:
LIQUID CRYSTALLINE COMPOSITION, CURED PRODUCT, OPTICALLY ANISOTROPIC LAYER, OPTICAL ELEMENT AND LIGHT GUIDE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2023/127538
Kind Code:
A1
Abstract:
A first problem to be addressed by the present invention is to provide a liquid crystalline composition which is capable of forming a film that has excellent light resistance, while enabling the achievement of excellent alignment properties of a liquid crystalline compound in a film. A second problem to be addressed by the present invention is to provide a cured product, an optically anisotropic layer, an optical element and a light guide element, each of which is obtained from the above-described liquid crystalline composition. A liquid crystalline composition according to the present invention contains a compound A and an antioxidant; the compound A has a partial structure represented by formula (I); the compound A exhibits liquid crystallinity; in cases where the composition does not contain a liquid crystalline compound B which has a different structure from the compound A, the distance ∆HSP between the HSP value of the antioxidant and the HSP value of the compound A is 10.5 MPa0.5 or less; and in cases where the composition contains the liquid crystalline compound B, the distance ∆HSP between the HSP value of the antioxidant and the average HSP value of the HSP value of the compound A and the HSP value of the liquid crystalline compound B is 10.5 MPa0.5 or less. In formula (I), each of A1 and A2 independently represents an optionally substituted aromatic hydrocarbon ring group or aromatic heterocyclic group; and * denotes a bonding position.
