ABSTRACT:
Mixtures of (1) reaction products obtained from (a) epoxides, for example polyglycidyl ethers of bisphenol A, (b) primary amines having 2 to 8 carbon atoms and (c) polymerized fatty acids, for example dimerized or trimerized linoleic acids and linolenic acids, and optionally (d) difunctional compounds, for example epichlorohydrin, acrylic acid or acrylonitrile, and (2) aminoplast precondensates, for example methylolated and lower alkyl-etherified melamine or urea, are useful as leather finishes and are preferably employed in the form of organic-aqueous emulsions.
