Abstract
An ink set including at least two inks. A first ink includes an optional colorant, a first multi-functional monomer, a second multi-functional monomer that is different from the first multi-functional monomer, and a peroxide initiator comprising a thermal free radical initiator. A second ink includes an optional colorant, a first multi-functional monomer, a second multi-functional monomer that is different from the first multi-functional monomer, and an amine activator having a catalyst which catalyzes the homolytic cleavage of the thermal free-radical initiator at low temperatures into radicals. The first ink is free of the amine activator and the second ink is free of the peroxide initiator. The first multi-functional monomer and the second multi-functional monomer accelerate reaction kinetics through a Trommsdorff effect. The components are each present in an amount relative to the other that provides a) early onset of gelation that accelerates polymerization, and b) an ink viscosity that is suitable for jetting from an ink jet printer.
