Abstract
A composition and method of associating stabilizer functionalities with latex particulates is provided. The composition can comprise a latex particulate configured for inclusion in an ink-jet ink to provide improved humidfastness of an image printed by the ink-jet ink, wherein the latex particulate has a molecular weight from 10,000 Mw to 10,000,000 Mw, and has a particle size from 10 nm to 2 μm; and an image stabilizer configured for improving lightfastness of the image, wherein the image stabilizer is bound to the latex particulate. The method can comprise the steps of coupling a polymerizable monomer with a stabilizing agent reactive with the polymerizable monomer, thereby forming a precursor stabilizer-containing monomer; polymerizing the precursor stabilizer-containing monomer to form a latex particulate; and decoupling the stabilizing agent from the latex particulate.
