PROBLEM TO BE SOLVED: To provide a polyester or poly (ester-urethane) graft-reaction product that exhibits properties of graft chains without degrading mechanical properties of a base resin. SOLUTION: This graft-reaction product has a polyester main chain, and a polymer from radical-polymerizable monomers as a side chain, the polymer from radical-polymerizable monomers satisfying requirement (1): the weight sum of an electron-accepting monomer having an e value of≥0.9 and an electron donating monomer having an e value of≤-0.6 is at least 50 wt.% of the total radical-polymerizable monomers in the polymer, and requirement (2): an aromatic, radical-polymerizable monomer is at least 10 wt.% of the total radical-polymerizable monomers in the polymer.
