Solvent-free UV-curable black ink composition applicable to pad printing process

摘要

The present invention is (A) a urethane acrylate oligomer; (B) a reactive monomer that is a mixture of two or more reactive monomers; (C) a photoreaction initiator; (D) black pigment; and (E) a solvent-free UV-curable black ink composition comprising an additive, a method of forming a bezel pattern using the same, a bezel pattern prepared thereby, and a display substrate including the same. The UV-curable black ink composition according to the present invention has excellent light-shielding properties even at a thin thickness, and has excellent light-shielding effect to a desired thin thickness on a substrate only by UV curing after pad printing, and it is possible to form patterns with excellent adhesion.
