Zusammenfassung:	To provide a polyol composition for forming hard polyurethane foam that uses a compatibilizer in a polyol mixture and yet achieves improved physical properties, and a hard polyurethane foam including the composition.SOLUTION: A polyol composition for forming hard polyurethane foam contains a polyol, a catalyst, a foam stabilizer, a foaming agent, and a compatibilizer. As the foaming agent, water and cyclopentane are used in combination therewith, and as the compatibilizer, chlorinated paraffin with an average number of carbon atoms of less than 18 is included.SELECTED DRAWING: None 【課題】ポリオール混合物に相溶化剤を用いつつ、物性を向上することができる、硬質ポリウレタンフォーム形成用ポリオール組成物、および該組成物を用いた硬質ポリウレタンフォームを提供すること【解決手段】ポリオール、触媒、整泡剤、発泡剤、および相溶化剤を含む硬質ポリウレタンフォーム形成用ポリオール組成物であって、発泡剤として水とシクロペンタンを併用し、相溶化剤として平均炭素数が１８未満である、塩素化パラフィンを含むことを特徴とする、硬質ポリウレタンフォーム形成用ポリオール組成物により解決する。【選択図】なし
