Abstract
Radiation curable coating compositions are disclosed. In some embodiments, the coating compositions are used to coat substrates such as packaging materials and the like for the storage of food and beverages. The coating compositions may have a (meth)acrylate functional polyether polyol prepared by reacting an epoxidized vegetable oil in the presence of a phosphoric acid compound to form an epoxy phosphate, and reacting the epoxy phosphate with a hydroxyl functional (meth)acrylatein the presence of an acid catalyst to form the(meth)acrylate functional polyether polyol.
