<P>PROBLEM TO BE SOLVED: To provide ink for inkjet recording giving a high image density, having excellent storage stability, improving the problem of clogging in an inkjet head, and showing excellent storage stability of a pigment dispersion liquid, and to provide an ink cartridge, an inkjet recording method, an inkjet recording device and an ink recorded material. <P>SOLUTION: The ink for inkjet recording comprises: a pigment dispersion liquid (A) containing at least carbon black, a dispersant, and water; and a self-dispersion type pigment dispersion liquid (B) containing carbon black having surface functional groups. The mass ratio (A<SB>c</SB>:B<SB>c</SB>) of the carbon black amount (A<SB>c</SB>) in the pigment dispersion liquid (A) to the carbon black amount (B<SB>c</SB>) having surface functional groups in the self-dispersion type pigment dispersion liquid (B) ranges from 98:2 to 50:50. <P>COPYRIGHT: (C)2009,JPO&INPIT |
