Abstract
The invention relates to aqueous dyestuff formulations which contain at least one telomer of the formula I ##STR1## or a salt thereof, in addition to at least one anionic dispersant and optionally further ingredients. In formula I the symbols have the following meanings: X is hydrogen or ##STR2## Y is hydrogen, --SO.sub.4 H or ##STR3## each of R.sub.1 and R.sub.2 independently of the other is hydrogen, C.sub.1 -C.sub.4 alkyl which is unsubstituted or substituted by a carboxyl group or is carboxyl; and the sum of n+m is an integer from 2 to 350. These compositions have good storage stability and redispersibility and are particularly suitable for use in the continuous dyeing process.
