A cholesteric liquid crystal mixture containing a compound represented by formula (Ia) : Z1-Y1-A1-Y3-M1-Y4-A2-Y2-Z2, a compound represented by formula (Ib) : Z3-Y5-A3-Y7-M2-P, and a tri- or higher functional polymerizable monomer suppresses deposition of a liquid crystal at the time of forming a film, exhibits a wide characteristic reflection bandwidth of a film to be obtained, and suppresses change of a reflection bandwidth caused when laminated glass is manufactured by laminating a liquid crystal film obtained by fixing a cholesteric liquid crystal phase of the film to be obtained with an interlayer film. Z1, Z2 and Z3 represent a polymerizable group; A1, A2 and A3 represent a spacer having an atom-bonding chain length of 1 to 30, provided that the spacer represents an alkylene group, or a linking group of multiple alkylene groups bonding to each other via -O- or -CO-; M1 and M2 represent (-T1-Y8)n-T2-; n indicates a natural number; when n is 2 or more, multiple (-T1-Y8)'s may be the same or different; T1 and T2 represent a saturated or unsaturated hydrocarbon ring, or a saturated or unsaturated heterocyclic ring, provided that the hydrocarbon ring and the heterocyclic ring may have a substituent; Y1, Y2, Y3, Y4, Y5, Y7 and Y8 each independently represent a single bond, -O-, -CO-, -O-CO-, -CO-O- or -O-CO-O-; and P represents a hydrogen atom or an alkyl group having 1 to 15 carbon atoms.
一种胆甾型液晶混合物,含有由式 (Ia) :Z1-Y1-A1-Y3-M1-Y4-A2-Y2-Z2、由式 (Ib) :Z3-Y5-A3-Y7-M2-P,以及一种三官能团或更高官能团的可聚合单体,可抑制成膜时液晶的沉积,使获得的薄膜具有较宽的特性反射带宽,并可抑制通过将获得的薄膜的胆甾液晶相固定而获得的液晶薄膜与中间膜层压而制造层压玻璃时引起的反射带宽变化。Z1、Z2 和 Z3 代表可聚合基团;A1、A2 和 A3 代表原子键合链长度为 1 至 30 的间隔物,条件是间隔物代表亚烷基,或通过 -O- 或 -CO- 相互键合的多个亚烷基的连接基团;M1 和 M2 代表 (-T1-Y8)n-T2-;n 表示自然数;当 n 为 2 或更多时,多个 (-T1-Y8) 可以相同或不同;T1和T2代表饱和或不饱和烃环,或饱和或不饱和杂环,条件是烃环和杂环可以具有取代基;Y1、Y2、Y3、Y4、Y5、Y7和Y8各自独立地代表单键、-O-、-CO-、-O-CO-、-CO-O-或-O-CO-O-;P代表氢原子或具有1至15个碳原子的烷基。
