Abstract:
1. A chiral liquid crystal precursor composition, the chiral liquid crystal precursor composition comprising (i) one or more nematic compounds A and (ii) one or more chiral dopant compounds B which are capable of giving rise to a cholesteric state of the chiral liquid crystal precursor composition, the chiral liquid crystal precursor composition being in a form of a spray coating composition, a knife coating composition, a roller coating composition, a screen coating composition, a curtain coating composition, a gravure printing composition, a flexography composition, an offset printing composition, a dry offset printing composition a letterpress printing composition, a screen-printing composition, or a pad printing composition, and comprising at least one salt in an amount effective to change a position of a selective reflection band exhibited by the composition in a cured state compared to a position of a selective reflection band exhibited by a composition in a cured state that does not contain the at least one salt.
