Aqueous dispersions of solids, especially dyestuffs and pigments, containing, as dispersing agent, a compound of the formula:
wherein
R is an aryl or arylene group which is free from aliphatic substituents containing 6 or more carbon atoms;
Y is -0-, -CH20- or -CO.O-;
m + n is from 3 to 30;
p is from 1 to 3;
q is 1 or 2;
X is S04 and r is 2-p, or X is PO4 and r is 3-p; and
M is H, NH4, a substituted ammonium radical or an alkali metal.
The dispersions are suitable for the preparation of print pastes based upon synthetic or natural thickening agents. The dispersions containing disperse dyestuffs are also suitable for the continuous dyeing of cellulose/polyester blends in conjunction with vat or cellulose reactive dyestuffs.
固体,特别是染料和颜料的水性分散体,其中含有作为分散剂的式化合物:
其中
R 是不含 6 个或更多碳原子的脂肪族取代基的芳基或芳基烯基;
Y 是-0-、-CH20-或-CO.O-;
m + n 是 3 至 30;
p 是 1 至 3
q 是 1 或 2;
X 为 S04,r 为 2-p,或 X 为 PO4,r 为 3-p;以及
M 是 H、NH4、取代的铵基或碱金属。
分散体适用于制备基于合成或天然增稠剂的印花浆。含有分散染料的分散体还适用于纤维素/涤纶混合物与 还原染料或纤维素活性染料的连续染色。
