Cholesteric liquid crystalline polymer(Ch-LCP) indicate selective reflection correspond to its helical structure's pitch. Novel Ch-LCP having both schiff base moiely as an acid lablie chiral-group and cross-linking group in polymer side chain have been developed. Photolysis of the system consists of the polymer and photo acid generator (PAG) was investigated. Clcavage of schiff base in lhe polymer was accelerated by photo generated acid. It was found that selective reflection wavelength of the polymer was controlled by UV irradiation and provide multi-colored selective reflection film having 100 μm line and space pitch. Furthermore, excellent thermal stability was achieved by crosslinking reaction of the Ch-LCP.
