WATER-BASED GRAVURE INK

The present invention relates to an aqueous gravure ink containing pigment particles A, polymer particles B and water, the aqueous gravure ink being capable of satisfying at least one of the following requirements 1 and 2: Requirement 1: an average particle size of whole particles in the aqueous gravure ink is not less than 150 nm and not more than 500 nm, and a polydispersity index in a particle size distribution of the whole particles is not less than 0.10 and not more than 0.30; and Requirement 2: an average particle size of the pigment particles A is not less than 140 nm and not more than 550 nm, and a polydispersity index in a particle size distribution of the pigment particles A is not less than 0.08 and not more than 0.32, and an average particle size of the polymer particles B is not less than 30 nm and not more than 220 nm, and a polydispersity index in a particle size distribution of the polymer particles B is not less than 0.08 and not more than 0.32. The aqueous gravure ink of the present invention is excellent in storage stability and is capable of providing a printed material that is excellent in rub fastness and adhesion properties.
