Method of making a phosphorescent toner

摘要

A method of making a toner composition including at least one phosphorescent pigment that absorbs energy released by natural or artificial light, and is able to be seen in a dark environment through luminescence of a certain color created by the energy released as light, is described. The phosphorescent toner has a particle size in the range of about 15 to 40 microns, which allows the toner to have the ability to absorb and then release the needed amount of light energy to be noticeable in a dark environment.

1. A method of forming a toner, the method comprising the steps of:
melt-blending binder resin particles; and admixing a total amount of uncoated phosphorescent pigment having an average particle diameter size in the range of about 16 μm to 55 μm to a total amount of the binder resin particles such that the total amount of the uncoated phosphorescent pigment and the total amount of the binder resin particles are melt-blended together.
