<p>PURPOSE: To obtain the subject stable composition, containing a reactive dye represented by a specific formula, having a high dye concentration without causing a rise in viscosity and crystal deposition even by preservation for a long period and useful for fibers. CONSTITUTION: This composition contains (A) at least one of a reactive dye of the formula [M is Li, Na or K), preferably further water and (B) a hydrophilic organic solvent and (C) 1-30wt.% urea and/orε-caprolactam and is obtained by regulating the inorganic salt concentration to <=1wt.%, e.g. <=0.1wt.%. Furthermore, the component (B), e.g. polyethylene glycol is preferably contained in an amount of 5-25wt.% based on the total amount of the ink composition.</p> |
