Ink composition, ink set and inkjet recording method

摘要

An ink composition includes: first particles (A) which are insoluble and dispersed in an aqueous dispersion medium, a polarity of the first particles (A) being one of positive and negative; and second particles (B) which are insoluble and dispersed in the aqueous dispersion medium, the second particles (B) including both a cationic group and an anionic group, the second particles (B) having a zeta potential that changes along with a change in pH of the aqueous dispersion medium, percentage of a water-soluble component in the second particles (B) being not higher than 5 % by mass.
