ABSTRACT:
The present invention comprises a blend of two polyamide resins (first and second). The first resin comprises dibasic derivatives of fatty acids, monobasic acid and organic polyamines. The second resin comprises isophthalic acid, dibasic derivatives of fatty acids and organic polyamines. The combination of the first and second resins in proportional amounts results in a water dispersible polyamide blend which exhibits good blocking and release properties as well as improved water dispersibility and pigment wetting. This blend is useful in flexographic ink compositions as well as Cold Seal Release Lacquer formulations.
