ABSTRACT:
A polyamide resin adapted for use in thermographic inks prepared from certain dimer acids and monomeric acids and a mixture of a diamine and a polyamine. The alkylene diamines and triamines, such as ethylene diamine and diethylene triamine, are preferred. With oleic acid dimer the monomeric acids are preferably stearic or isostearic acids and mixtures thereof. With the dimer of polyunsaturated acids the monomeric acid may also be the monomer residue from dimerized oleic acid.
