PROBLEM TO BE SOLVED: To provide a polyol composition capable of bonding a non-ferrous metal such as aluminum into sufficient strength in the case of using it as an adhesive composition and giving a good working environment, and the adhesive composition by using the same. SOLUTION: This polyol composition contains a castor oil-based polyol and a≥12 total carbon number acidic phosphoric acid ester compound. Also, the adhesive composition contains the castor oil-based polyol and the≥12 total carbon number acidic phosphoric acid ester compound and a polyisocyanate (crude MDI, etc.). As the acidic phosphoric acid ester compound, compounds obtained by performing the reaction of an epoxidized animal or plant oil and their esters (epoxidized soybean oil methyl, etc.) with phosphoric acids (ortho-phosphoric acid, etc.) are preferable. Further, it is preferable to contain terpenephenols in the polyol composition and the adhesive composition. COPYRIGHT: (C)2005,JPO&NCIPI
