Dyeing of cellulosic substrates with reactive dyes in the presence of at least 20 g/l of sodium chloride, employing auxiliaries (E) of levelling activity, which are methylene-bridge-containing and sulpho-group-containing aromatic compounds, obtainable by condensation of defined sulphonation products with formaldehyde resp. formaldehyde-yielding compounds and optionally salt formation; (E)-contaning compositions that further contain at least one hydrotrope (H) and/or at least one sequestering agent (Q); and novel condensation products.

Dyeing process and auxiliary

(A) oligohydroxy-C.sub.3-8 -alkanes containing at least 3 hydroxy groups and (B) KOH, that contain at least 5% by weight of K.sup.+ and at least one alcoholic hydroxy group are eminently suitable as oxyalkylation catalysts, in particular for the oxyalkylation of ester group-containing substrates, before all of natural, vegetable or animal fats or oils or their modification products.

Condensates and their use as oxyalkylation adjuvants

Compounds of formula I ##STR1## in which R.sub.1 is isooctyl, nonyl or dodecyl, R.sub.2 is H or --SO.sub.3 R.sub.6, R.sub.3 (A--O).sub.m R.sub.5 where each A, independently, is --C.sub.2 H.sub.4 --, --C.sub.3 H.sub.6 -- or --C.sub.4 H.sub.8 --, R.sub.4 is (B--O).sub.n R.sub.5 where each B, independently, is --C.sub.2 H.sub.4 --, --C.sub.3 H.sub.6 -- or --C.sub.4 H.sub.8 --, R.sub.5 is H or --SO.sub.3 R.sub.6, provided that at least one R.sub.5 is --SO.sub.3 R.sub.6, R.sub.6 is H, an alkali metal, an equivalent of an alkaline earth metal or optionally substituted ammonium, m is 1, 2 or 3 and n is 0, 1 or 2, provided that m+n is at most 4, when n=0 then R.sub.5 is H and m=1, when only one group R.sub.5 is --SO.sub.3 R.sub.6 and n=1 or 2 then both R.sub.2 's are H, are useful as emulsifying and dispersing agents, especially as dyeing or printing assistants for dyeing or printing a substrate dyeable with anionic or disperse dyes.
