CHOLESTERIC POLYMER LIQUID CRYSTAL-FORMING COMPOSITION AND CHOLESTERIC POLYMER LIQUID CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide a method utilized for displaying or coloring by improving defects such that much labor is required, a fine control of its color shade is also difficult and in many cases the color is shifted from the objective color in a method of using conventional thermotropic liquid crystal and a lyotropic liquid crystal, using a material available easily and at a low cost, performing the control and fixation of the helical pitch simply and effectively and generating the objective color tone in a high definition. ;SOLUTION: This composition is obtained by containing a cholesteric polymer liquid crystal-forming compound containing an acyl derivative of a hydroxyalkylcellulose as a main component with an energy ray curable compound. Also, a wavelength control of the reflective light of the cholesteric liquid crystal is performed and at the same time or in succession by performing an energy ray irradiation, the cholesteric polymer liquid crystal consisting of the acyl derivative of hydroxyalkylcellulose having fixed cholesteric helical structure is obtained.;COPYRIGHT: (C)2000,JPO
