On the other hand, when the hydroxyl value exceeds 150, the pot life when mixed with polyisocyanate (II) becomes short, which poses a practical problem. The hydroxyl value of the copolymer (1) can be adjusted by the type and amount of the monoethylenically unsaturated monomer having a hydroxyl group, which is the component (B).
