PROBLEM TO BE SOLVED: To provide a seal having both good heat resistance and weather resistance of acrylic polyol and good workability (low viscosity and low temperature sensitivity) and flexibility of polyoxyalkylene polyol. Provided is a polyol composition for materials. SOLUTION: Each terminal has at least one hydroxyl group, The (meth) acrylic copolymer (a) and the polyoxyalkylene polyol (b) composed of monomers containing a (meth) acrylic acid ester monomer as essential components are used as essential components, The system copolymer (a) Hydroxyl value is 15 mgKOH / g or more, 40 mgKOH / g g and a number average molecular weight (Mn) of 3,000 or more, 2,000 or less, and the weight ratio of (a) and (b) ((a) / (B)) is greater than 1/3 and less than 3/1. |
