ABSTRACT:
Provided is an ink jet ink capable of achieving both high colorability and excellent bleeding resistance of an image. The ink jet ink includes at least a pigment and a star polymer in which at least three copolymer chains of α,β-ethylenically unsaturated monomers are bonded to a central skeleton, in which the copolymer chains of the α,β-ethylenically unsaturated monomers are copolymers of at least one first monomer selected from the group consisting of aromatic (meth)acrylates and aromatic (meth)acrylamides and at least one second monomer selected from the group consisting of acid monomers and salts of the acid monomers.
