Presently described are energy-curable resins, compositions, thermosets, coatings, and methods thereof. The curable resins described herein are (meth)acrylated resins derived from distilled tall oil rosin acids, distilled tall oil fatty acids, or a combination thereof. The curable resins can also include derivatives from rosin acids and/or fatty acids, such as cycloaddition products. The curable compositions undergo fast curing using UV and/or EB and provide enhanced performance of coatings, films, and printing inks, especially adhesion, stability and flexibility.
