LOW MELT COLOR TONERS WITH FLUORESCENCE AGENTS
First Claim
1. A toner comprised of toner particles comprising at least one amorphous polyester comprised of an alkoxylated bisphenol based polyester, a crystalline polyester derived from the reaction of an aliphatic dicarboxylic acid or aromatic dicarboxylic acid with an aliphatic diol, at least one colorant and at least one fluorescence agent.

Abstract
A low melt or ultra low melt toner includes at least one amorphous polyester of an alkoxylated bisphenol based polyester, a crystalline polyester derived from the reaction of an aliphatic dicarboxylic acid or aromatic dicarboxylic acid with an aliphatic diol, at least one colorant and at least one fluorescence agent. Methods of authentication of the toner, of authentication of documents formed from the toner, of embedding information in documents, and the like are also set forth.

14. A method for authentication of a toner, comprising
forming a toner comprised of toner particles comprising at least one amorphous polyester, at least one crystalline polyester, at least one colorant and at least one fluorescence agent, wherein the color exhibited by the at least one fluorescence agent upon exposure to activating energy to which the at least one fluorescence agent is sensitive such that is fluoresces is known, exposing the toner to the activating energy to which the at least one fluorescence agent is sensitive such that is fluoresces, and determining if the toner exhibits the known color of the at least one fluorescence agent during exposure by comparing the exhibited color to the known color.

16. A method of forming an image, comprising:
-
with a toner set comprised of a plurality of toners, a first toner of the toner set comprised of toner particles comprising at least one amorphous polyester, at least one crystalline polyester, at least one colorant and at least one fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the at least one toner, forming a latent image of a first pattern on a photoreceptor, developing the first pattern with the first toner, and subsequently transferring the developed first pattern to a recording medium, and forming a latent image of a second pattern on a photoreceptor, developing the second pattern with an additional toner different from the first toner, and subsequently transferring the developed second pattern to the recording medium. - View Dependent Claims (17, 18, 19, 20)
