Abstract: An ink composition includes an acrylic resin including a polymerization product of a first monomer having a hydroxyl group, a second monomer having an epoxy group, a third monomer having an acrylate group, and a fourth monomer having a substituted or unsubstituted phenyl group, a first curing agent having an isocyanate group, and a second curing agent having an amine group. Durability and abrasion resistance of a window may be improved.

Abstract: A window module including a window, a first print layer, an ink layer, and a protective layer covering the ink layer. The protective layer includes a polymer resin polymerized from monomers including a first monomer which is an acrylic monomer substituted with a hydroxy group, a second monomer having an epoxy group, and at least one of a third monomer having a substituted or unsubstituted phenyl group or a fourth monomer which is an acrylic monomer having a substituted or unsubstituted bicyclic alkyl group, and thus, has excellent durability, chemical resistance, and abrasion resistance.
