Abstract
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, and a method of forming and using the toner are described. The phosphorescent toner has a particle size in the range of about 15-40 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.
Claims22
A phosphorescent toner for producing an image on a substrate, the phosphorescent toner comprising:
- an uncoated phosphorescent pigment for forming a luminescent image on the substrate, wherein the uncoated phosphorescent pigment has an average particle size in the range of about 15 μm to about 55 μm.
A method of forming a toner, the method comprising the steps of:
- melt-blending binder resin particles;
- and
- admixing a colorant, and uncoated phosphorescent pigment, having an average particle diameter size in the range of about 15 μm to 55 μm to the binder resin particles.
A toner for producing a phosphorescent image on a substrate, the toner comprising:
- a colorant for forming an image on a surface of a substrate;
- and
- an uncoated phosphorescent pigment having an average particle size in the range of about 15 μm to about 55 μm for forming the phosphorescent image on the substrate.
