    摘要: Disclosed are stable, concentrated, aqueous dyestuff preparations comprising water, an anionic dispersing agent and at least one cold-dyeing water soluble fibre reactive dye, said dye having an average particle diameter of less that 20 .mu., other optional constituents being one or more disperse dyes, acid, such as acetic acid, to adjust the pH of the preparation to a preferred value of 4 to 6, and organic solvents. The preparations are useful for the convenient production of dyebaths for dyeing substrates containing a fibre reactive dyeable component.
