An infrared transmitting ink composition for inkjet, a method of forming a bezel pattern using the same, a bezel pattern manufactured thereby, and a display substrate comprising the same are disclosed. The ink composition may check alignment marks using an infrared camera and detect pressure marks by non-destructive inspection even after the bezel pattern thereof is printed on a display substrate, and also may improve the adhesion to the substrate and the performance of inkjet process. The infrared ray transmitting ink composition for ink jet comprises a lactam black pigment, a dispersant, an epoxy compound, a vinyl ether compound, an oxetane compound, a photopolymerization initiator and an organic solvent.
