ABSTRACT:
Disclosed herein is a process for bringing amino-type compounds such as amines, amides, imines and proteins, containing --NH.sub.2 and .dbd.NH groups, into liquid form, usually a solution, by reaction with glyoxals. The resulting liquids, which can dissolve further materials such as natural and synthetic fibres, are especially useful as hardeners for collageneous materials used in the preparation of films such as sausage casings. An especially preferred preparation for this purpose comprises an animal hide fibre composition and a precondensate formed from collagen scrap, e.g. waste skin casing or leather scraps, dissolved in a solution of glyoxal.
