    摘要： A process for purifying a composition comprising: i) an encapsulated pigment comprising a pigment and an encapsulant material comprising a cross-linked dispersant; ii) a liquid medium; and iii) free dispersant; said process comprising removal of at least some free dispersant from the composition using a membrane having a molecular weight cut-off of 3 to 30 times the weight average molecular weight of the dispersant prior to cross-linking, with the proviso that all of conditions a), b) and c) are met: a) the pigment is not silicon dioxide; b) the cross-linked dispersant is not cross-linked polyethyleneimine; and c) the cross-linked dispersant is not a dispersant which has been cross-linked with bis-ethene,1,1′-[methylene bis(sulfonyl)].

    摘要： A process for manufacturing an ink, or pigment formulation (e.g. a concentrate) for use in inks, comprising filtration of a composition comprising a particulate pigment and a liquid medium through an inorganic filter having pores of a uniform size below 10 microns. The process accurately removes oversized particles that could cause problems in inkjet printers without wasting non-problematic under-sized pigment. High flow rates are achieved even with low trans-filter pressure differences. In one embodiment, high flow rates are maintained by selection of pH and/or ionic strength. The filters are more robust than conventional polymeric filters and withstand cleaning with aggressive cleaning agents.

    摘要翻译： 用于制造用于油墨的油墨或颜料制剂（例如浓缩物）的方法包括通过具有均匀尺寸低于10微米的孔的无机过滤器过滤含有颗粒状颜料和液体介质的组合物。 该过程精确地去除了可能在喷墨打印机中引起问题的超大颗粒，而不浪费无问题的小尺寸颜料。 即使使用低的反滤器压力差也可获得高流量。 在一个实施方案中，通过选择pH和/或离子强度来维持高流速。 过滤器比传统的聚合物过滤器更坚固，并且可以耐腐蚀性清洁剂进行清洁。

    摘要： A process for preparing an encapsulated particulate solid using an epoxy functional cross-linking agent and a carboxylic acid functional dispersant characterized in that the crosslinking is performed in the presence of a borate compound. The resultant solids are useful in, for example, ink jet printing inks where high optical density prints may be obtained.
