摘要： Bleed control and fast dry times are achieved in pigment-based ink-jet ink compositions by formulating the ink compositions to include at least one appropriately modified pigment in a water-insoluble organic compound, which is microemulsified with an amphiphile and water. By employing a vehicle formulated in accordance with the invention, the present pigment-based ink-jet ink compositions are bleed-free and fast-drying and exhibit the inherent waterfastness of pigments. Moreover, the use of a modified pigment improves print quality by passivating the pigment particles to eliminate agglomerations between the particles and by providing pigment particles of substantially uniform size, thereby yielding more uniform thickness and coverage on a print medium. In short, pigment-based ink-jet ink compositions formulated in accordance with the invention offer the best qualities of pigments as colorants while reducing or eliminating the problems conventionally associated therewith.
摘要翻译： 通过配制油墨组合物以在水不溶性有机化合物中包含至少一种适当改性的颜料，其用两亲物和水进行微乳化，从而在颜料基喷墨油墨组合物中实现了渗色控制和快速干燥时间。 通过使用根据本发明配制的载体，本发明的颜料基喷墨油墨组合物是无渗透和快干的并且表现出颜料固有的耐水性。 此外，改性颜料的使用通过钝化颜料颗粒以消除颗粒之间的团聚并通过提供基本均匀尺寸的颜料颗粒来改善印刷质量，从而在印刷介质上产生更均匀的厚度和覆盖。 简而言之，根据本发明配制的颜料基喷墨油墨组合物提供颜料作为着色剂的最佳品质，同时减少或消除常规与之相关的问题。

摘要： An electrokinetic device is configured as a dynamic lens cover and/or filter for an imaging assembly, e.g., of a mobile device, to selectively allow electromagnetic radiation to pass through a lens of the imaging assembly when the dynamic lens cover is in a first operating state or to prevent electromagnetic radiation from reaching the lens of the imaging assembly when the dynamic lens cover is in a second operating state. The electrokinetic device includes transparent first and second substrates, and a compaction trench surrounding the lens of the imaging assembly. The compaction trench stores pigment when the dynamic lens cover is in the first operating state. In the second operating state pigment is dispersed within a carrier fluid between the first and second substrates.
