ABSTRACT:
A flexible packaging printing ink is formulated from a copolymer of polyethyleneneglycol methacrylate and a polyamide resin, pigment, solvent and cellulose acetate butyrate. The polyamide resin is prepared by condensing a dibasic acid mixture with a diamine mixture. The dibasic acid mixture comprises about 0.5 to 0.8 equivalents of a C.sub.20 -C.sub.44 dibasic acid mixture comprised of about 60 to 100% dimers, 0 to 40% trimers and 0 to 5% monomers, and about 0.2-0.7 equivalents of at least one C.sub.6 -C.sub.12 dibasic acid such as azelaic acid and adipic acid, while the diamine mixture comprises about 0.5-0.8 equivalents of piperazine or a substituted piperazine and the balance comprises at least one C.sub.2 -C.sub.12 alkyl diamine such as ethylene diamine.
