The present invention relates to the use of water-dispersible and/or water-emulsifiable amphiphilic co-oligomer of fatty crotonates and radical-copolymerizable hydrophilic ethylenically unsaturated acids and/or anhydrides thereof which may also contain small quantities of other copolymerizable comonomers, for the oiling and optionally waterproof finishing of leathers and skins.

Leather oiling preparations and their use

Leather oiling compositions and their use

Aqueous dispersions containing special aminopropionic acid derivatives and co-oligomers based on fatty crotonates are suitable for the oiling of leather. The leathers thus treated are distinguished by high resistance to washing and cleaning and by impermeability to water.

An aqueous dispersion of amphiphilic oligomers for oiling leather or skins wherein the dispersion contains anionically modified urethane fatty oligomers containing long-chain hydrocarbon fatty groups containing from 8 to 40 carbon atoms, together with salt-forming carboxylic acid groups, sulfonic acid groups and mixtures thereof, which form urethane fatty oligomers having an at least predominantly linear basic structure of the oligomer molecule.

The invention concerns a method of preparing preferably highly concentrated aluminum triformate solutions containing alkali metals and/or alkaline earth metals, by the neutralization of an alkaline aluminate solution containing alkali metals and/or alkaline earth metals by adding formic acid, and subsequently heating the solid precipitated to give a clear, stable aluminum triformate solution. The invention also concerns highly concentrated aluminum triformate solutions containing alkali metals and/or alkaline earth metals and the use of such solutions to impregnate textiles, in disinfectant and cleaning agents, as a coagulant for paints, or as a setting agent in leather processing.
