An ink composition for ink-jet textile printing comprises (a) at least a reactive dye; (b) water; and (c) at least an organic solvent which is a C4-C6 polyhydric alcohol having one or less primary alcohol groups. The reactive dye may be selected from monochlorotriazinyl, sulfatoethylsulfone and vinylsulfone derivative dyes and the C4-C6 polyhydric alcohol may include hexylene glycol, 1,2-butanediol, 2,3-butanediol etc. The ink composition may also further include a buffer, a microbicide and a surfactant e.g acetylene glycol. A method of using the ink composition for dyeing and printing of materials containing cellulose fibres such as cotton is also disclosed. |
