摘　　要：大多数喷墨打印墨水是阴离子型的,在涂料中需要加入阳离子固色剂来提高打印质量.本研究中直接采用阳离子型分散剂聚二烯丙基二甲基氯化铵(poly-DADMAC)分散颜料,提高了涂料的稳定性,改善了纸张对打印墨水的固色性,增加了打印颜色密度,扩大了颜色密度范围,同时也避免了传统阴离子分散剂与阳离子固色剂不能兼容而导致的结块现象.The most of ink-jet printing ink is anionic, cationic fixing agent should be added to improve the printing quality. Cationic disperser poly-DADMAC is studied in this research to increase the stability of coating color, increase the density of ink-jet printing, broaden the scope of the color, and the problem which caused by the incompatibility between the anionic disperser and cationic fixing agent can be avoided by first cationically dispersing the pigment with poly-DADMAC.
