The invention concerns the use of water-soluble or water-dispersible compounds containing polyalkylene oxide chains and nitrogen, prepared by reacting compounds of general formula (I), in which R is a z-valent alkoxy residue, AO is 1-100 alkylene oxide units composed of 0-100 C2?H4?O units, 0-50 C3?H6?O units and 0-30 C4?H8?O units, Hal represents chlorine and/or bromine atoms, p is a whole number between 0 and 3 and q is 0 or 1, provided that p + q is not equal to 0, and z is a whole number from 1 to 10, with ammonia, C1-22?-alkylamines and/or aliphatic di- and/or polyamines, to remove printing ink from recycled printed paper and/or paper processing water. L'invention concerne l'utilisation de composés contenant des chaînes d'oxydes de polyalkylènes et de l'azote solubles ou dispersibles dans l'eau, préparés par transformation de composés de formule générale (I), où R désigne un résidu alcoxy de valence z, AO 1 à 100 unités d'oxydes d'alkylène, qui se décomposent en 0 à 100 unités de C2H4O, 0 à 50 unités de C3H6O et 0 à 30 unités de C4H8O, Hal désigne des atomes de chlore et/ou de brome, p un nombre entier entre 0 et 3 et q 0 ou 1, à la condition que la somme p + q ne soit pas égale à 0, et z un nombre entier de 1 à 10, avec de l'ammoniac, des alkylamines avec 1 à 22 atomes de C et/ou des diamines et/ou des polyamines aliphatiques, pour éliminer les encres d'imprimerie sur les vieux papiers imprimés et/ou dans les eaux de recyclage du papier.
