The invention relates to reactive dyes for ink-jet printing. A series of reactive monoazo dyes derived from γ acid were synthesized, the printing quality of the inks made from the dyes were evaluated and compared with those of the commercial inks. The materials printed include photo papers, glossy papers, A4 papers and pretreated cotton. Based on the data of CIE Lab, it is found that inks made from the inventive dyes have smaller ΔE and better fastness against water and light. The printing quality of the inventive inks is better than those of the commercial inks. The inventive dyes can solve current problems such as complicate operation process and the treatment required for high polluted waster water produced associated with the conventional printing industry, such that not only the cost and time are saved, but also the demand of diversity required by customers can be satisfied.
本发明涉及用于喷墨打印的反应性染料。合成了一系列源自γ酸的反应性单偶氮染料,评估了由这些染料制成的墨水的打印质量,并与商业墨水进行了比较。打印材料包括相纸、光泽纸、A4纸和预处理的棉布。基于CIE Lab数据,发现由本发明染料制成的墨水具有更小的ΔE值,以及更好的耐水和耐光性。本发明墨水的打印质量优于商业墨水。本发明的染料可以解决传统印刷工业中的当前问题,例如操作过程复杂以及对产生的高污染废水进行处理的需求,从而不仅可以节省成本和时间,还可以满足客户对多样化的需求。
