ABSTRACT:
Cross-linkable nylon compositions used as coatings for nylon and polyester substrates are disclosed. These compositions comprise a water-soluble polyamide derived from select polyether diamines and select aliphatic dicarboxylic acids, a water-soluble formaldehyde-derived crosslinking agent, and optionally an acid catalyst. Processes for their application in coating substrates and various coated articles are also described.
