Abstract
An ink composition, including 20% or less pigment, 10% or less dispersant, between 50% and 75% acrylate with acrylate being a mixture of a trifunctional acrylate monomer, a tetrafunctional polyester acrylate oligomer, and an optional difunctional polyester acrylate oligomer, 12% or less photoinitiator, and wherein an effective amount of the trifunctional acrylate monomer in combination with the tetrafunctional polyester acrylate oligomer, and the optional difunctional polyester acrylate oligomer provides the ink composition with a near-zero shear viscosity between 2×10cP and 5×10cP at 25° C., and between 2.×10cP and 4.×10cP at 60° C., and a 60 second tack between 40 and 65 g-m at 25° C., and between 10 and 20 g-m at 60° C., and an energy of activation between 15 and 180 at kJ/mol at 1 rad/s, and between 40 and 120 at kJ/mol at 100 rad/s.
