    • 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活性染料。 合成了一系列由γ酸衍生的反应性单偶氮染料,评价了由染料制成的油墨的印刷质量,并与商业油墨进行了比较。 印刷的材料包括照片纸,光面纸,A4纸和预处理的棉花。 基于CIE Lab的数据,发现由本发明染料制成的油墨具有较小的DeltaE和对水和光的更好的牢度。 本发明油墨的印刷质量优于商业油墨的印刷质量。 本发明的染料可以解决目前的问题,例如复杂的操作过程和与常规印刷工业相关的高污染废水所需的处理,从而不仅节省了成本和时间,而且消除了客户所需的多样性需求 满意。
