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.

Polyamide of dimer acids, alkylene diamine and polyalkylene polyamine

Thermoplastic core-shell compositions having a rigid core, a rubbery acrylic shell and transition layer intermediate between the core and shell layers and formed of the core and shell monomer components have excellent elastomeric properties. Although the rigid and rubbery components include interreactive functional monomers, the resulting elastomers remain thermally processable in extrusion and injection molding equipment.
