摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.
