PROBLEM TO BE SOLVED: To provide a multicolor reflection plate, which enables regulating color in broad range with small quantity of UV ray and to maintaining excellent alignment, and its preparation. SOLUTION: In a multicolor reflection plate having a non-fluidized layer, which is formed by grandjean aligning a cholesteric liquid crystal polymer being a copolymer containing an optically active group-containing monomer as one component and forms plural kinds of reflection area having different reflection wavelength based on the difference in an effective component content of the optical active group, the non-fluidized layer contains photo-acid generator and/or its photo-decomposed compound and also the photo-acid generator has a carbon-carbon double bond between the carbon atom combining with a carbon atom of a triazin ring and its adjacent carbon atom.
