<P>PROBLEM TO BE SOLVED: To provide an ink for an inkjet-recording, improved in image density while sufficiently securing viscosity stability on preserving it at high temperatures, a method of inkjet-recording by using the ink and an ink cartridge housing the ink in a container. <P>SOLUTION: This ink for the inkjet-recording is provided by containing at least a pigment, an alcohol alkoxylate-based surfactant, a water-soluble organic solvent and water, dispersing the pigment by using a dispersant expressed by general formula (1) [wherein, R<SP POS="POST">1</SP>is 1-4C alkyl or allyl, or 1-8C aralkyl; (L) is an integer of 0 to 7; and (n) is an integer of 20 to 80] and having ≤36 mN/m dynamic surface tension in the case that foam life at 25°C measured by a maximum bubble pressure method is 15 msec. <P>COPYRIGHT: (C)2012,JPO&INPIT |
