Abstract
One aspect of the present invention relates to the use of a polyamide as a binder for printing inks, wherein the polyamide is a reaction product (P) of (1) one or more compounds which are chosen from the group of primary and/or secondary monoamines and polyamines with (2) a dimer fatty acid and (3) a carboxylic monoacid, with the proviso that the dimer fatty acid (2) building block of (P) contains at least 30% by weight of monomer fatty acid.
Claims18
A method of binding a printer ink to a substrate, the method comprising using a polyamide as a binder for a printing ink, wherein the polyamide is a reaction product (P) of
- (1) one or more amines selected from the group consisting of primary and secondary monoamines and polyamines,
- (2) a dimer fatty acid, and
- (3) a carboxylic monoacid, with the proviso that the dimer fatty acid contains at least about 30% by weight of a monomer fatty acid.
A laminating ink composition for laminated packaging applications, the ink comprising:
- (i) a polyamide, wherein the polyamide is a reaction product (P) of
- (1) one or more amines selected from the group consisting of primary and secondary monoamines and polyamines
- (2) a dimer fatty acid and
- (3) a carboxylic monoacid,
- with the proviso that the dimer fatty acid contains at least 30% by weight of a monomer fatty acid,
- (ii) a colorant;
- and
- (iii) an organic solvent.
