Abstract (en)
[origin: WO2021130091A1] To provide a composition capable of forming a polyurethane foam having excellent filling properties, surface properties, and strength. A polyurethane resin composition containing a polyol component and a polyisocyanate component, in which the polyurethane resin composition contains a compound (A) as the polyol component or a component other than the polyol component, the compound (A) has a molecular weight of 220 or less, has two or more reactive groups capable of reacting with an isocyanate in one molecule, and has one reactive group with a reaction activity with an isocyanate group that is higher than the reaction activity with an isocyanate group of the other reactive groups of compound (A), and the ratio of the hydroxyl value of the compound (A) to the hydroxyl value of the polyol component is 1.2 or more, provided that when the compound (A) falls under the polyol component, the phrase "the hydroxyl value of the polyol component" refers to the hydroxyl value of the polyol component other than the compound (A).
