Abstract
A UV curable ink composition that comprises a ultraviolet light curable ink composition comprising at least one acrylated oligomer, a pigment, and a photoinitiator is provided. The ink composition of the present invention has a viscosity from about 300 centipoise at 25° C. to about 10000 centipoise at 25° C. In one variation the at least one acrylated oligomer includes an aliphatic acrylated urethane oligomer and an epoxy oligomer. In another variation the ink composition includes an acrylic oligomer.
