Abstract: Methods of making fluorescent metallic toners are provided which comprise forming one or more fluorescent latexes which comprise a fluorescent agent, a first type of amorphous resin, and a second type of amorphous resin, wherein the first and second types of amorphous resins are present at a ratio in a range of from 2:3 to 3:2; forming a mixture comprising the one or more fluorescent latexes; a dispersion comprising aluminum flakes and a surfactant; one or more emulsions which comprise a crystalline resin, the first type of amorphous resin, the second type of amorphous resin; and optionally, a wax dispersion; aggregating the mixture to form particles of a predetermined size; forming a shell over the particles of the predetermined size to form core-shell particles; and coalescing the core-shell particles to form a fluorescent metallic toner. Fluorescent metallic toners and methods of using such toners are also provided.
