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.摘要翻译: 胶体晶体用组合物包括各自具有核和壳的核 - 壳粒子(A)和具有特定结构的单体(B1)。 核 - 壳粒子(A)构成组合物的25〜65重量%,单体(B1)构成组合物的35〜75重量%。 芯的平均粒度在50〜900nm的范围内。 壳由由具有特定结构的苯乙烯和单体(B2)中的至少一种构成的线性聚合物形成。 线性聚合物的一端共价结合到芯上。 芯(n(芯))的折射率满足下式(2)和(3):其中R 1表示氢原子或甲基,y为0或1,n-壳 - 核心‰ 0.07其中n(壳)表示壳的折射率,n B-n核‰¥0.07,其中n(B)表示固化后单体(B1)的折射率。
