MIXTURES OF REACTION PRODUCTS BASED ON EPOXIDES, PRIMARY AMINES AND FATTY ACIDS AND OF AMINOPLAST PRECONDENSATES, THEIR PREPARATION AND THEIR USE AS LEATHER DRESSINGS

摘要

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) polymerised fatty acids, for example dimerised or trimerised 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-ether-ified melamine or urea, are useful as leather finishes and are preferably employed in the form of organic-aqueous emulsions.
