Abstract
Impulse ink jet compositions are provided which are suitable for printing clear, well-defined alphanumeric text or low spread, narrow bar width bar codes on porous substrates such as Kraft paper or corrugated cardboard. The inks may also contain an antioxidant that lowers the dissolved oxygen level in the ink, thereby enhancing the jetting performance of the printhead.
