Polyamide resins useful as binders in flexographic/gravure inks are provided which are essentially free of polyeric fat acids. These polyamide resins exhibit improved water solubility, yet still retain the other many desirable properties of polyamide resins based on polymeric fat acids. The resins are acid terminated having acid values greater than 30 and are prepared from medium chain (12-26 carbons) dicarboxylic acids such as the C. sub. 21 acid, 2-n-hexyl-5-(7-carboxyl-n-heptyl)-cyclohex-3-ene carboxylic acid, and aliphatic diamines having from 2-12 carbon atoms.

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.

A flexible packaging printing ink is formulated from a resin binder (e. g. an alcohol soluble polyamide or a water-dispersible polyacrylate), pigment, solvent (e. g. a lower alkanol or water), and an alkyl polyglycoside surfactant. Related methods, compositions and articles are also provided. A method of preparing a polyamide resin by condensing a dibasic acid mixture with a diamine mixture and melt blending the resin with an alkyl polyglycoside is also provided. These polymers are particularly useful as the binder for a flexible packaging laminating ink composition.

Water soluble polyamide resins are produced from an excess aromatic dicarboxylic acid and a diamine. The resin can be used in inks.

Polymeric fat acid polyamides are disclosed useful in the flexographic ink industry, to provide products which will comply with environmental protection standards. The improvement lies in the use of acid termination with acid values of 8-20 and a sufficient amount of unsaturated monomeric fatty acids to provide a molecular weight product which will permit relatively high solids levels and reduced solvent emission while maintaining good ink varnish properties.
