    Abstract: A polymerized rosin compound includes a rosin dimer component (A) including a bifunctional rosin dimer component (a1) represented by formula (1): ROOC—X—COOR. In this formula, X represents a rosin dimer residue derived from abietic acid, neoabietic acid, or palustric acid, which are resin acids having conjugated double bonds; and R represents hydrogen, an alkyl group of I to 5 carbon atoms, or a benzyl group. The rosin dimer component (A) contains a bifunctional rosin dimer component (a1) in the amount of 80% by weight or more and a rosin trimer or higher oligomer component (B) in the range from 1.5 to 3.7% by weight, wherein the rosin dimer component is free of a monofunctional rosin dimer component (a2) having one functional group represented by formula (2): ROOC—, wherein R represents hydrogen, an alkyl group of 1 to 5 carbon atoms, or a benzyl group, and free from functional group containing rosin dimer component (a3), wherein the functional group represented by formula (2): ROOC—, wherein R represents hydrogen, an alkyl group of 1 to 5 carbon atoms, or a benzyl group. The polymerized rosin compound contains a large amount of the bifunctional rosin dimer component that makes it possible to obtain linear polymer with a high molecular weight.
