Zusammenfassung:PROBLEM TO BE SOLVED: To provide a polyurethane resin composition which suppresses lowering of flame retardancy after left at a high temperature (or can keep high flame retardancy even after left at high temperature), namely, is excellent in heat-resistant stability of the flame retardancy.SOLUTION: A polyurethane resin composition contains polyol (A) containing polymerized oil (A1) of castor oil (a1) and vegetable oil (a2), polyisocyanate (B), and a phosphate-based flame retardant (C).SELECTED DRAWING: None 【課題】高温放置後の難燃性の低下が抑制された(或いは高温放置後でも高い難燃性を維持できる)、すなわち難燃性の耐熱安定性に優れるポリウレタン樹脂組成物を提供すること。【解決手段】ヒマシ油(a1)と植物油(a2)との重合油(A1)を含有するポリオール(A)、ポリイソシアネート(B)、及びリン酸エステル系難燃剤(C)を含有する、ポリウレタン樹脂組成物。【選択図】なし
