Abstract

1. A process for crosslinking casein films in leather finishing, wherein the casein is applied in layers together with a water-soluble condensate of melamine and/or urea with formaldehyde and, if appropriate, glyoxal and any methylol groups present may be etherified with a lower alcohol, drying is effected at from 20 to 80 degrees C after each application, and crosslinking is carried out by from one to three heat treatments in the absence of an acidic catalyst at from 140 to 200 degrees C for from 0.1 to 5 seconds in each case.
