Abstract: New ball point pen ink compositions are utilized to enhance the performance and very substantially extend the service life of ball pen ink cartridges by preventing the formation of an ink flow-blocking mass at the entrance to the brass or bronze nib or a mass which prevents the movement of the follower plug in a copper alloy cartridge. This is accomplished by dispersing in the ink proper one or more additives effective to prevent oxygen and moisture, which enter the cartridge and pass into the ink, from reacting with the metal constituents of the cartridge assembly to form metallic ions which react with ingredients of the ink proper in the formation of a flow-blocking mass.
