Zusammenfassung:	An ink composition and an ink cartridge having the ink composition are provided. The ink composition includes a colorant and an aqueous carrier. The ink composition has a dissolved gas content of less than 3 ppm as measured on the basis of the amount of dissolved oxygen gas at 20° C. at 20° C., a static surface tension at 25° C. of greater than 34 dynes/cm, and an advancing contact angle relative to an ink receiving receiver of less than about 55° at room temperature. The ink container can be a collapsible bag.
