摘要:
An improved process for tanning leather by treating animal skins with a water-soluble melamine-formaldehyde resin in the presence of an acid catalyst towards the end is improved by using a melamine-formaldehyde resin which is at least partially etherified with a glycol ether, alkyl glycol ether, or both.
