Abstract (en)
[origin: US5501707A] PCT No. PCT/EP92/01938 Sec. 371 Date May 3, 1994 Sec. 102(e) Date Mar. 3, 1994 PCT Filed Aug. 24, 1992 PCT Pub. No. WO93/05188 PCT Pub. Date Mar. 18, 1993.The invention is a process for oiling of leather and skins which imparts washing and dry-cleaning resistance to the treated leather and skins and a composition useful in the process. The washing and dry-cleaning resistance of leather is improved by impregnating the leather with an aqueous dispersion of a co-oligomer containing residues of a partial ester of maleic acid and acrylic acid and/or methacrylic acid and optionally up to 45% by weight of residues of ether hydmphilic and oleophilic monomers. The composition can contain semiesters of sulfosuccinic acid as additional oiling agents.
