Film-Printable UV-Curable Ink Composition, Method for Producing Bezel Pattern Using Same, Bezel Pattern Produced by Same, and Foldable Display Substrate Comprising Same

Abstract

A film-printable UV-curable ink composition, a method for forming a bezel pattern using the same, a bezel pattern, and a display substrate comprising the bezel pattern are disclosed herein. In some embodiments, the ink composition includes a black pigment, a dispersant, an alicyclic epoxy compound, an oxetane compound, an acrylic or silicone surfactant, an organic solvent having a boiling point of 200° C. or more, a photosensitizer, a photopolymerization initiator and an adhesion promoter, wherein a weight ratio of the epoxy compound to the oxetane compound is 1:3 to 1:5. The bezel pattern produced by the ink composition is thin and yet has excellent light-shielding properties so as to prevent a panel pattern of a foldable display, such as a mobile device, from being visible and light leakage from occurring.
