摘要： A process and apparatus collects pigment nanoparticles by forming a vapor of a pigment that is solid at room temperature, the vapor of the pigment being provided in an inert gaseous carrying medium. At least some of the pigment is solidified within the gaseous stream. The gaseous stream and pigment material is moved in a gaseous carrying environment into or through a dry mechanical pumping system. While the particles are within the dry mechanical pumping system or after the nanoparticles have moved through the dry pumping system, the pigment material and nanoparticles are contacted with an inert liquid collecting medium.

摘要： A process and apparatus prepares and collects metal nanoparticles by forming a vapor of aluminum or copper metal that is solid at room temperature, the vapor of the metal being provided in an inert gaseous carrying medium. At least some of the metal is solidified within the gaseous stream. The gaseous stream and metal material is moved in a gaseous carrying environment into or through a dry mechanical pumping system. While the particles are within the dry mechanical pumping system or after the nanoparticles have moved through the dry pumping system, the vaporized metal material and nanoparticles are contacted with an inert liquid collecting medium.

摘要： The present invention describes a novel method for the formation of optically variant pigments by the coating of layers onto a substrate and the fracturing of the coated material into pigment particles after the coating operation and novel pigments produced thereby. Coating techniques such as slot die coating (especially multiple slot die coating), spin coating, meniscus coating, curtain coating, and the like have proven successful. It is preferred that multiple die slots are used to coat multiple layers in a single pass so that manufacturing costs are minimized. The use of these coating techniques, and especially multiple die slot coating, allows for many layers to be coated, with from three to fifty layers being readily possible. This offers a relatively inexpensive way of coating out a wide variety of layers, and especially the pigment materials needed for optically variable pigments, quickly and with high quality. The coating materials may be sols, polymers, composites, reactive mixtures and the like, including combinations of these materials. The properties of the optically variable pigment are determined by the composition, properties and thickness of the coated layers.
摘要翻译：本发明描述了一种通过将涂层涂覆到基材上并在涂布操作之后将涂层材料压裂成颜料颗粒形成光学变体颜料的新方法和由此制备的新型颜料。诸如槽模涂布（特别是多槽模涂布），旋涂，弯液面涂布，幕涂等涂层技术已被证明是成功的。优选地，使用多个模槽来单次涂覆多层，使得制造成本最小化。使用这些涂覆技术，特别是多个模具槽涂层，允许涂覆许多层，其中三至五十层是容易实现的。这提供了相对便宜的方式，可以快速且高质量地涂覆各种各样的层，特别是光学可变颜料所需的颜料。涂层材料可以是溶胶，聚合物，复合材料，反应性混合物等，包括这些材料的组合。光可变颜料的性质由涂层的组成，性质和厚度决定。

摘要： The present invention provides a process for adhering a liquid to a particulate substrate. The process comprises the steps of:a) providing an apparatus which can create an oscillating magnetic field within a chamber,b) providing particulate magnetic material within the chamber of said apparatus while said oscillating field is active,c) having in the chamber within the oscillating magnetic field a liquid coating material and a particulate substrate to be coated with said liquid,d) and having said magnetic field form a fluidized bed of at least said particulate magnetic material, said liquid coating material coating the surface of the particulate substrate, ande) optionally continuously collecting the coated particulate substrate.The particulate magnetic material may be added to the chamber before or after the magnetic field has been activated to oscillate. The field may be active when the magnetic particles are added, and the field may be activated only after the magnetic particles are present as a non-fluidized sedentary bed. The liquid may likewise be added at any time. The liquid coating material may be added before the field is activated, or after the field is activated. The liquid may be added before the magnetic particles are added, at the same time or after the magnetic particles are added. The magnetic particles may provide the only particulate surface onto which the liquid is to be coated, or separate particulates may be used along with the magnetic particulate materials. The magnetic particulates may be included along with the non-magnetic particulates in the final desired product, or the coated magnetic particles may be easily separated from the non-magnetic particles by magnetic filtering or screening. This process provides a significant benefit in a liquid coating process by reducing the potential for waste and allowing easy recycling of coating material.
