A polyurethane resin composition without handling trouble is obtained by a combination of a copolyether polyol obtained by copolymerization of tetrahydrofuran and a 3-alkyl tetrahydrofuran at a mixing molar ratio of 85/15-20/80, a polyisocyanate compound and an active hydrogen atom-containing compound. The 3-alkyl tetrahydrofuran is preferably 3-methyl tetrahydrofuran. |
