Radiation curable ink compositions and coating compositions contain an aliphatic (meth)acrylate functional macromonomer, a reactive acrylate monomer, and a photoinitiator. Ink compositions also contain an effective amount of a colorant or pigment. These inks, when cured by exposure to actinic radiation, have excellent durability, weatherability, and adhesion to acrylate substrates such as polymethylmethacrylate.
