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.

Abstract: An ink composition includes a base resin including an acrylic resin, a multifunctional curing agent having four or more functional groups, a pigment dispersed in the base resin, and a matting agent having a median particle size in a range of about 1.0 μm to about 2.0 μm and dispersed in the base resin. Accordingly, a single-layered printed layer formed from the ink composition may have improved light-shielding properties, surface hardness, durability, and adhesion strength.
