具有高颜色饱和度的光泽颜料
摘要：
本发明涉及具有特定颗粒尺寸的着色光泽颜料，包括具有组成SiO0.03－SiO0.95的氧化硅的透明核和，视需要，具有高折射指数的二氧化硅，碳，部分透明金属和/或电介质的其它层；涉及一种适用于此的涂布方法，其中金属硅在低氧分压的存在下蒸气沉积；涉及这些光泽颜料在着色塑料，表面涂层，印刷油墨和化妆品组合物的用途；以及涉及包含这些光泽颜料的着色组合物。
摘要（英）：

The invention relates to coloured gloss pigments having specific particle dimensions comprising a transparent core of a silicon oxide of the composition SiO0.03 to SiO0.95 and, optionally, further coatings of silicon dioxide, carbon, a partially transparent metal and/or a dielectric of high refractive index, to a coating method suitable therefor wherein metallic silicon is vapour-deposited in the presence of a low oxygen partial pressure, to the use of such gloss pigments in pigmenting plastics, surface coatings, printing inks and cosmetic compositions, and also to pigmented compositions comprising such gloss pigments.
