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.
