PROBLEM TO BE SOLVED: To obtain a resin for offset printing ink excellent in gloss and flowability without spoiling antimisting properties in printing. SOLUTION: This rosin-modified phenol resin is produced by using 100 pts. mass component (A) obtained by reacting a rosin (1), a dimer acid (2), a resol type phenol resin (3) and a polyhydric alcohol(4) and 1-20 pts.mass component (B) comprising≤10 pts.mass monomer acid component,≥70 pts.mass dimer acid component and≤20 pts.mass trimer acid component.
