摘要：
Disclosed are an aqueous pigment dispersion and an ink composition which can realize high print density. The aqueous pigment dispersion comprises at least water and a surface-modified carbon black, the surface-modified carbon black being dispersible and/or dissolvable in water without any dispersant and having a hydrophilic functional group content/specific surface area value of 5 to 30 µmol/m 2 .
