Abstract
Use as cellulose cross-linking agents of derivatives of alkanepolycarboxylic acids corresponding to general formula I: ##STR1## in which: n, m=0 or 1, PA0 R.sub.1, R.sub.3, R.sub.5 and R.sub.7 =H or COOH it being understood that at least two of the substituents from the said substituents R.sub.1, R.sub.3, R.sub.5 and R.sub.7 represent a carboxyl group, PA0 R.sub.2, R.sub.4, R.sub.6, R.sub.8 =H or PO(OH)(OR) where R=H or Alk C.sub.1 -C.sub.4, it being understood that only one substituent from the said substituents R.sub.2, R.sub.4, R.sub.6 and R.sub.8 represents said PO(OH)(OR) group, textile finishes containing said products of formula I and new derivatives of formula I.
