Dyes are an important component of drop‐on‐demand ink‐jet inks and are commonly used in desktop printers. While they offer bright, vivid colour, these dyes exhibit poor light and water fastness. To combat this, researchers have started using pigmented ink‐jet inks instead of dye‐based inks to improve light and water fastness, but the pigments are insoluble in ink vehicles. To use pigments, dispersants must be applied; however, this is a delicate process because the properties of the dispersant substantially affect how the pigmented mill base must be prepared. In this study, polymeric dispersants are synthesised based on the properties and ratios of monomers and the molecular weights of polymers. In total, 14 types of polymeric dispersants are synthesised and examined, with special attention paid to the dispersing properties of particle size reduction and the stability of the pigmented mill base used to prepare drop‐on‐demand ink‐jet inks. This study describes the synthesis of the dispersants in terms of their suitability for commercial application.

合成聚合物分散剂，以应用于用于喷墨油墨的炭黑颜料研磨料

染料是按需喷墨墨水的重要组成部分，通常在台式打印机中使用。尽管它们提供明亮，鲜艳的色彩，但它们的耐光性和耐水性却很差。为了解决这个问题，研究人员已开始使用有色喷墨油墨代替基于染料的油墨，以提高耐光性和耐水性，但该颜料不溶于油墨载体。要使用颜料，必须使用分散剂。但是，这是一个微妙的过程，因为分散剂的性质会显着影响必须制备有色研磨基料的方式。在这项研究中，基于单体的性质和比例以及聚合物的分子量合成了聚合物分散剂。总共合成并检查了14种类型的聚合物分散剂，特别注意降低粒度的分散性和用于制备按需滴注喷墨油墨的着色磨粉机的稳定性。这项研究从分散剂的商业适用性方面描述了它们的合成。
