FIELD: chemistry.
SUBSTANCE: invention relates to radiation curable coating compositions. Radiation-curable coating composition comprises a polyether-polyol with methacrylate functional groups. Method for producing a coating composition comprises reacting an epoxidised vegetable oil with a phosphoric acid compound to produce an epoxy-phosphate. Reaction is then carried out between epoxy-phosphate and methacrylate with hydroxyl functional groups in the presence of an acid catalyst to produce a polyether-polyol with methacrylate functional groups.
EFFECT: improved adhesion, flexibility and mouldability.
