Alcohol-soluble polyamides and printing inks
First Claim
1. A polyamide, alcohol soluble at room temperature, prepared by the condensation of an acid component comprising(A) dimerized fatty acids having from 16 to 44 carbon atoms with(B1) at least one aliphatic linear monocarboxylic acid having 3 to 6 carbon atoms, and(B2) at least one aliphatic branched monocarboxylic acid having 4 to 9 carbon atoms, the equivalence ratio between components (A) and (B) ranging from 0.73:
- 0.27 to 0.6;
0.4, and each of the components (B1) and (B2) being present in an amount of at least 0.1 equivalent, based on unit total acid equivalent, and an amine component comprising(C) ethylenediamine and(D) hexamethylenediamine, the equivalence ratio between component (C) and (D) ranging from 0.7;
0.3 to 0.4;
0.6.

Abstract
Polyamides which are alcohol-soluble at room temperature, are useful in formulating printing inks, and which comprise dimerized fatty acids, at least one aliphatic unbranched monocarboxylic acid and at least one aliphatic branched monocarboxylic acid as the acid component, and ethylenediamine and hexamethylenediamine as the amine component, and printing inks formulated therefrom.
