Abstract
An ink composition for ink jet recording is described comprising a pigment, a resin dispersant, a thermoplastic resin emulsion and water, wherein the weight ratio of the pigment to the resin dispersant is from 20:1 to 5:2. The foregoing ink composition is little susceptible to irregular bleeding on a recording medium, undergoes no change in physical properties and jettability and no precipitation of solid matter and exhibits an excellent redispersibility.
