PROBLEM TO BE SOLVED: To provide a binder for a publication-grade gravure printing ink, usable as a homogeneous solution of an alicyclic organic solvent, and exhibiting balanced binder performance such as transferability of ink, and drying performance and gloss of ink layer. SOLUTION: The binder for the publication-grade gravure printing ink is produced by using a resin composition obtained by salt-forming reaction of a rosin (A) containing 5-34 wt.% of a polymerized rosin (a1), a fatty acid (B), an amine (C) containing a monoamine having a 10-20C alkyl group and/or a monoamine having a 10-20C alkenyl group and a metal compound (D) in the alicyclic organic solvent (E).
