Abstract
Ink for ink-jet dyeing purposes contains a disperse dye which is insoluble, or slightly soluble, in water, and a dispersing agent which can be represented by the following general formula (I). EQU M--(--OCH.sub.2 CH.sub.2 --).sub.n --X--(--CH.sub.2 CH.sub.2 O--).sub.n --M Here, X in this formula represents --A-- or --O--A--O-- (where A is represented by the formulae indicated below), and M is a hydrogen atom, --SO.sub.3 H, --SO.sub.3 NH.sub.4 or --SO.sub.3 Na, and n is an integer of value 5-20. ##STR1## According to the above ink, there is no blockage of the orifices by the ink and the ink can be discharged from the orifices in the form of very fine liquid droplets which are stable, and mixing of the inks which have be discharged on the surface of the said cloth proceeds smoothly, thereby enabling to obtain uniform and distinct images with no physical defects or color defects. Another aspect is directed to a method of forming mixing color on a material to be dyed. According to this method, the mixing color is obtained by mixing a first ink for ink-jet dyeing with a second ink for ink-jet dyeing having a color which is different from that of the first ink on the material to be dyed,…
