(57) [Problem] To provide a urethane resin composition which does not bleed from a blended base resin for a long period of time and can reduce deterioration of a coating film surface and the like. SOLUTION: A modified polyisocyanate having an isocyanate group at a molecular terminal and modified by a binding unit substantially free of urethane bond, which is derived by a reaction of the isocyanate group, and a monopoly as an active hydrogen component Provided is a urethane resin composition having an isocyanate group content of 0.5% or less, which is obtained by reacting with an all. The obtained urethane resin composition can be suitably used as a plasticizer, does not bleed for a long period of time even when blended with the base resin, and can maintain a good plasticizing effect of the base resin. |
