Abstract
Abstract A curable composition which provides a cured product which imparts improved drying properties to alkyd paints. An oxyalkylene polymer having reactive silicon group is combined with at least one other oxyalkylene polymer which is either one containing hydroxyl group and having a number average molecular weight of not less than 4,000 or one having essentially no hydroxyl group.
