Abstract:
1. A radiation curable solid ink composition comprising: at least one curable wax that is curable by free radical polymerization, wherein the at least one curable wax is present in an amount of from about 1 to about 25% by weight based upon the total weight of the curable solid ink composition; at least one monomer, oligomer, or prepolymer, wherein the at least one monomer, oligomer, or prepolymer is present in an amount of from about 1 to about 80% by weight based on the total weight of the curable solid ink composition; wherein the at least one monomer, oligomer, or prepolymer has a melting point of from about 45 to about 80° C.; at least one non-curable wax, wherein the non-curable wax is present in an amount of from about 20 to about 50% by weight based upon the total weight of the curable solid ink composition; at least one free-radical photoinitiator, wherein the photoinitiator or photoinitiators are present in a total amount of from about 0.5 to about 15% by weight based upon the total weight of the curable solid ink composition; and a colorant; wherein the components form a curable ink composition that is a solid at a first temperature, wherein the first temperature is from about 20 to about 25° C.; wherein the components form a liquid composition at a second temperature, wherein the second temperature is greater than about 40° C.
