An ink-jet printing dye-fixing agent comprises a quaternary cationic polymer having the main chain represented by general formula (1):
where R1, R2, R3, and R4 are independently an aliphatic alkyl group of 1 or 2 carbons; R is an aliphatic alkylene group of 1-6 carbons or a phenylene group; and n is an integer of from 3 to 300. A recording paper sheet employing the fixing agent has excellent ink dye fixability, and the agent makes ink coloring excellent and improves water resistance of printed matter.
一种喷墨印花固色剂包括具有通式(1)代表的主链的季阳离子聚合物:
其中 R1、R2、R3 和 R4 分别为 1 或 2 个碳原子的脂肪族烷基;R 为 1-6 个碳原子的脂肪族亚烷基或亚苯基;n 为 3 至 300 之间的整数。使用该固色剂的记录纸张具有极佳的油墨染料固色性,该固色剂还能使油墨着色极佳,并提高印刷品的耐水性。
