Abstract
Quaternary compounds of the formula [(K.sup..sym..sub.m --X--).sub.n R]m.multidot.n.multidot.An.sup..crclbar. wherein K.sup..sym. denotes a cationic organic radical, X denotes a linking member, R denotes the radical of a heterocyclic reactive group, m denotes the numbers 1 or 2, n denotes the numbers 1 or 2 and An.sup..crclbar. denotes an anion, can be used for increasing the affinity of anionic dyestuffs for natural or synthetic fibre materials containing nitrogen or hydroxyl groups.
