Disclosed is an organic phase change carrier and a method for forming same, and a phase change ink including same. The organic phase change carrier comprises a colloidal dispersion of nanoparticles exhibiting a substantially uniform distribution of said nanoparticles discretely distributed therewithin, at least one curable monomer; a phase change inducing component, and an initiator. The organic phase change carrier exhibits a substantially uniform distribution of the nanoparticles so that they are discretely distributed therewithin, and are substantially resistant to the aggregation of the nanoparticles distributed therewithin.
