LYOTROPIC CHROMONIC LIQUID CRYSTAL COMPOSITION

摘要

PURPOSE: A lyotropic chromonic liquid crystal composition is provided to obtain an optical film with the high surface hardness by enhancing the molecule cohesion of a liquid crystal dye and a base film. CONSTITUTION: A lyotropic chromonic liquid crystal composition contains a basic chromonic liquid crystalline compound including a basic functional group and an acid monomer including an acidic functional group. The basic chromonic liquid crystalline compound is formed with a structure which the basic functional group is surrounding a hydrophobic core(10) composed of an aromatic molecule. The basic functional group expresses a nitrogen ion by reacting with the acid monomer.
