PURPOSE: A radiation curable ink composition is provided to be the liquid of low viscosity in an uncured state, to form an image with resistance to cracking and fading, and to impart durability to the image. CONSTITUTION: A radiation curable ink composition comprises a radiation curable material, a polymeric dispersant, and a fluorescent nanoparticle composition. A method of forming an image comprises: melting a radiation curable phase change ink comprising a radiation curable material, a polymeric dispersant, an optional non-fluorescent colorant including pigment, dye, mixtures of dyes, mixtures of pigments, mixtures of dyes and pigments, and the like, and a fluorescent nanoparticle composition; jetting the radiation curable phase change ink onto an image receiving substrate, wherein the radiation curable phase change ink forms a gel state; exposing the radiation curable phase change ink on the image receiving substrate to ultraviolet light to cure the curable components of the radiation curable phase change ink.
