ABSTRACT:
Polyamide resins are prepared from aromatic dicarboxylic acids and which are substantially free of dimeric or higher polymeric fat acids. The resins generally have improved alkaline water solubility or dispersibility having substantially lower solution viscosities than prior polyamide resins. The harder resins with their water solubility find particular utility as ink binders. The softer resins find utility as a film layer bonding two flexible substrates.
