Abstract
An ultraviolet curable black ink composition, a bezel pattern forming method using the same, a bezel pattern produced by the method, and a display substrate including the bezel pattern; are disclosed herein. In some embodiments, an ultraviolet curable ink composition includes a black pigment, a dispersant, an epoxy compound, an oxetane compound, a light diffusing agent, a photopolymerization initiator, and an organic solvent. The ultraviolet curable black ink composition is developed to be applied to a cover window film of a foldable display, has excellent light shielding properties and folding properties at a thin thickness, and as a light diffusing agent is applied to the ink, prevents surface wrinkles from generating due to a difference in the curing rate of the upper and power portions of a bezel, by means of UV curing alone without a pretreatment process.
