High-gloss multilayer effect pigments having a chromatic interference color and a narrow size distribution, and method for the production thereof
Abstract:
Multilayer pearlescent pigments comprising platelet-shaped transparent substrates provided with an optically active coating, where the optically active coating includes at least a) an absorbing high-index layer A having a refractive index n≧1.8 b) a low-index layer B having a refractive index n
Abstract(Chinese):

多层珠光颜料包括设置有光学活性涂层的片状透明基板，其中光学活性涂层至少包括a）具有折射率n≥1.8b的吸收性高折射率层A）低折射率层B，具有 折射率n <1.8c）折射率n≥1.8的高折射率层C，以及d）任选的至少一个外保护层D，其中多层珠光颜料具有体积平均尺寸分​​布的累积频率分布 功能，其指数为D10，D50，D90，跨度和Dgr; D在0.7-1.4的范围内，跨度＆Dgr; D根据式（I）＆Dgr计算; D =（D90-D10）/ D50 一世）。 本发明进一步涉及一种生产这些多层珠光颜料的方法，以及它们的用途。
