ABSTRACT:
An ink composition, suitable for use in jet printing, comprises a dye in a solvent consisting of water and lower alkylene glycol which is highly soluble in both water and the lower alkylene glycol, which is chemically stable for long periods in the solvent, has high tinctorial power and is resistant to fading by light. The ink composition is characterized by its ability to reduce the evolution of gases from solution at reduced pressure. The ink composition is further characterized by an adjusted pH of about 3 to about 6. In addition, the ink composition may contain preservatives to prevent fungus and bacteria growth.
