    摘要: A composition for colloidal crystals includes core-shell particles (A) each having a core and a shell, and a monomer (B1) having a particular structure. The core-shell particles (A) constitute 25% to 65% by weight of the composition, and the monomer (B1) constitutes 35% to 75% by weight of the composition. The core has an average particle size in the range of 50 to 900 nm. The shell is formed of a linear polymer composed of at least one of styrene and a monomer (B2) having a particular structure. One end of the linear polymer is covalently bonded to the core. The refractive index of the core (n(core)) satisfies the following formulae (2) and (3):
    wherein R 1 denotes a hydrogen atom or a methyl group, and y is 0 or 1, n shell - n core ≥ 0.07
    wherein n(shell) denotes the refractive index of the shell, and n B - n core ≥ 0.07
    wherein n(B) denotes the refractive index of the monomer (B1) after curing.
