    摘要： The present invention relates to novel pearlescent pigments based on substrates comprising at least one selectively light absorbing layer, which consists of a chalcogenide and/or oxychalcogenide, preferably sulfides or oxysulfides. The coatings can be directly prepared by the precipitation of chalcogenides in liquid suspension onto the substrates. Preferably, metal oxides or mixed metal oxides are coated onto the substrate; the resulting precursor is transferred into a furnace and calcined under a sulfurizing gas flow to convert the oxides into oxysulfides and/or sulfides depending on the reaction parameters. The conversion to sulfides and/or oxysulfides is preferably carried out in a fluidized bed reactor. Angle-dependent optical pigments are thus produced, which are especially useful in paints, powder coatings, paper coatings, plastics, cosmetics, inks and security-enhancing features as well as ion decorative applications for foods and drugs.

    摘要翻译： 本发明涉及基于包含至少一个选择性光吸收层的基材的新型珠光颜料，其由硫族化物和/或氧化硫化物，优选硫化物或氧硫化物组成。 可以通过将液体悬浮液中的硫族化物沉淀到基底上来直接制备涂层。 优选地，将金属氧化物或混合金属氧化物涂覆在基材上; 将所得前体转移到炉中并在硫化气流下煅烧，以将氧化物转化为氧硫化物和/或硫化物，这取决于反应参数。 转化为硫化物和/或氧硫化物优选在流化床反应器中进行。 因此制造了依赖于角度的光学颜料，其特别适用于涂料，粉末涂料，纸张涂料，塑料，化妆品，油墨和安全性增强特征以及食品和药物的离子装饰应用。

    摘要： There is provided a process of packaging metal pigment in a substantially non-dusting manner. The process includes the step of dampening the metal pigment with a liquid which may be water or an organic solvent compatible with that pigment type. The dampened pigment is then placed into a porous container which is sealed prior to removal of the liquid. The porosity of the container is chosen to permit removal of the liquid (for example by evaporation and/or centrifugation) whilst retaining substantially all of the pigment. Suitable containers include paper bags (such as autoclave bags), woven fiber materials (optionally calendered or coated) and polymer materials. The substantially dry metal pigment can be conveniently stored or transported within the container and is in a convenient form to use in a powder coating process.
