TONER COMPOSITIONS. The present invention relates to phosphorescent coated pigments being provided which may be used in toner compositions. In embodiments, the phosphorescent pigment may be coated by a spray coating process. Large pigment particles can be combined dried with dried resin latex particles, whereby coating the pigment surface, followed by heating and shearing in a rotary kiln or extruder to fuse the toner resin and fuse it to the pigment surface. The resulting coated particles may be used with other toners in color toner embodiments to provide phosphorescent images. |
