Provided is a urethane resin composition obtained by a method comprising: a step for melting and mixing isocyanate (B), antioxidant (C), release agent (D), and dispersant (E) to obtain a molten mixture; and a step for mixing the molten mixture and a polyol (A). The release agent (D) is a compound represented by general formula (1); R1- COOH, the dispersant (E) is a compound represented by general formula (2) having a weight-average molecular weight Mw of 16,000 or less; and the dispersant (E) content of the urethane resin composition is between 0.1 and 5.0 mass%. |
