A poly(oxyalkylene) substituted xanthene colorant is provided having the following structure :
where Y is a poly(oxyalkylene) substituent having a straight or branched polymer chain of from 3 to 400 monomer units selected from ethylene oxide, propylene oxide, butylene oxide and glycidol ;
R1 and R2 are independently selected from H, C1-C8 alkyl, aryl and Y, provided that if either R1 or R2 are Y, the other is not H ;
R3 and R4 are independently selected from H, C1-C4 alkyl, C1-C4 alkoxy, Cl, Br and I;
X is selected from H, S03-, CO2- and COOR5, where R5 is C1-C4 alkyl or aryl ; and
each Z is independently selected from S03-, CO2-, COORs, Cl, and OH, where R6 is C1-C4 alkyl or aryl, and n is 0, 1, 2 or 3.
The colorant is synthesized using a novel poly(oxyalkylene) substituted aminophenol intermediate.
一种聚(氧烷基)取代的氧杂蒽着色剂具有如下结构 :
其中 Y 是聚氧亚烷基取代基,具有 3 至 400 个单体单元的直链或支链聚合物 链,这些单体单元选自环氧乙烷、环氧丙烷、环氧丁烷和缩水甘油;
R1 和 R2 独立选自 H、C1-C8 烷基、芳基和 Y,但如果 R1 或 R2 是 Y,则另一个不是 H;
R3 和 R4 独立选自 H、C1-C4 烷基、C1-C4 烷氧基、Cl、Br 和 I;
X 选自 H、S03-、CO2- 和 COOR5,其中 R5 为 C1-C4 烷基或芳基;以及
每个 Z 独立选自 S03-、CO2-、COORs、Cl 和 OH,其中 R6 是 C1-C4 烷基或芳基,n 是 0、1、2 或 3。
该着色剂是利用新型聚(氧烷基)取代氨基苯酚中间体合成的。
