Abstract

Procedure for stabilizing halogenotriazine reactive dye preparations, or mixtures of such dyes, containing a triazin-2-ylamino group substituted by at least one halogen atom in the triazinyl ring, characterized in that the dyes or mixtures of dyes before or during its preparation or after isolation of the reaction mixture as a buffer agent, a carboxylic acid buffer is added, which maintains a pH between 5.0 and 8.0 in the aqueous solution.
