1. A polyurethane composition comprising
(A) a urethane compound prepared by reacting 100 parts by weight of a polyol with a polyisocyanate such that the NCO/OH equivalent weight ratio is greater than 0.5 but less than 15, and
(B) a dimer of a linear olefin compound having 6 to 30 carbon atoms,
wherein the content of said compound (B) per 100 parts by weight of said polyol is greater than 5 parts by weight but less than 400 parts by weight.
