Abstract
An energy curable inkjet ink includes a nitroxy inhibitor, a compound having an ethylenic unsaturated bond, a photoinitiator, a coloring agent, and a stray light resistance index of at least 7. A method of preparing an energy curable inkjet ink with stray light resistance includes providing a nitroxy inhibitor; providing a mixture of a compound having an ethylenic unsaturated bond, and a photoinitiator, and a coloring agent; combining the nitroxy inhibitor and the mixture to obtain the energy curable inkjet ink and thereby to increase a stray light resistance index of the energy curable inkjet ink to at least 7.
