KR940003443A - Optical polarized particles and manufacturing method thereof - Google Patents

Abstract

The present invention is a pyrazine 2,3-dicarboxylic acid, pyrazine 2,5- which is a base forming material of the light polarizing particles in the presence of a polymer dispersant which has no affinity with the polymer resin to be a film medium and enhances the dispersion effect of the light polarizing particles. An optical polarizer is prepared by reacting an iodine compound with a substance selected from dicarboxylic acid, pyridine 2,5-dicarboxylic acid, oxyquinoline, dihydrocinchonitine sulfate and 2-oxypyridine.

Said polymeric dispersing agent is polyhydroxyethyl methacrylate, polyacrylic acid. Preference is given to any one of cellulose acetate, oxypropyl acrylate and nitrocellulose. Said optical polarization particle size is 1 micrometer or less, More preferably, it is 0.1-0.3 micrometers. The optically polarized particles according to the present invention are dissolved in one solvent selected from polyhydroxyethyl methacrylate, polyacrylic acid, cellulose acetate, hydroxypropyl acrylate, and nitrocellulose to form a solution of a polymer dispersant, and the polymer dispersant solution One of pyrazine 2,3-dicarboxylic acid, pyrazine 2,5-dicarboxylic acid, pyridine 2, 5-dicarboxylic acid, oxyquinoline, dihydrocinchonaidine sulfate and 2-oxypyridine, which will form the basis for the photopolarized particles The material may be selected and added together with the iodine compound and prepared by reacting the optically polarized particle base-forming material with the iodine compound in a solution of the polymer dispersant.
