Abstract
An ink composition including an epoxy resin, and an amine curing agent. The epoxy resin is formed by reacting a bifunctional epoxy monomer, an adipic acid, and a polyisocyanate. The ink composition is formed by mixing the epoxy resin and the amine curing agent. The preparing of the epoxy resin includes mixing an epoxy functional monomer and an adipic acid to form an epoxy intermediate, and mixing the epoxy intermediate with a polyisocyanate to form the epoxy resin.
