Zusammenfassung:1. Process for re-tanning mineral-tanned leathers, characterised in that sulphonic acids, and salts thereof, of the general formula see diagramm : EP0024014,P5,F5 wherein R represents the radical see diagramm : EP0024014,P5,F6 see diagramm : EP0024014,P5,F7 see diagramm : EP0024014,P5,F8 R1 represents hydrogen or methyl, X represents hydrogen, an alkali metal ion, in particular a sodium or potassium ion, or an ammonium ion and n represents a number from 1-4, and wherein SO3 X is bonded to phenyl, are used as the re-tanning agents.
