Patent number: 9529294Abstract: In accordance with various embodiments of the invention, a method of forming an ultraviolet security toner for use in printing hardware originally designed to use chemically prepared toner includes melt-blending binder resin particles and optionally a charge-control agent, a colorant and a releasing agent. The fluorescent pigment is then admixed to the melt-blended particles to form a fluorescent pre-toner. A first inorganic material is then blended with the fluorescent pre-toner, coating the particles of the fluorescent pre-toner with the first inorganic material. A second inorganic material is then blended with the coated pre-toner, adding another layer of coating to the fluorescent pre-toner. The first inorganic material has an average particle diameter size that is less than the average particle diameter size of the fluorescent pigment particles and the second inorganic material has an average particle diameter size less than that of the first inorganic material.Type: GrantFiled: September 17, 2015Date of Patent: December 27, 2016Assignee: TROY GROUP, INC.Inventors: Kevin L. Heilman, Michael R. Riley

Patent number: 9442402Abstract: 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.Type: GrantFiled: May 26, 2015Date of Patent: September 13, 2016Assignee: TROY GROUP, INC.Inventors: Carrie Gilson, Kevin L. Heilman, Michael R. Riley

Patent number: 9141009Abstract: A coating composition, system, and method for printing documents that are difficult to chemically or physically forge and that are easy to visually verify are disclosed. The system includes a substrate, a toner, including a colorant and a dye, a primary migration-enhancing coating applied using an offset printing process and optionally a secondary migration-enhancing coating applied using an offset printing process. An image formed using the toner of the invention is readily verified by comparing a colorant-formed image and a dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.Type: GrantFiled: August 18, 2009Date of Patent: September 22, 2015Assignee: TROY GROUP, INC.Inventors: Eugene Hoefs, Michael R. Riley, Kevin L. Heilman

Patent number: 8747997Abstract: A coating composition, system, and method for printing documents that are difficult to chemically or physically forge and that are easy to visually verify are disclosed. The system includes a substrate, a toner, including a colorant and a dye, a coating including fluorescent material, e.g., a primary migration-enhancing coating, applied using an offset printing process and optionally a secondary migration-enhancing coating applied using an offset printing process. An image formed using the toner of the invention is readily verified by comparing a colorant-formed image and a dye-formed image and/or to a reverse negative imaged formed by the dye quenching the fluorescent material. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.Type: GrantFiled: October 18, 2010Date of Patent: June 10, 2014Assignee: Troy Group, Inc.Inventors: Kevin L.

Patent number: 7842445Abstract: A toner for printing documents that are difficult to chemically or physically forge and that are readily easy to visually verify and methods of using and forming the toner are disclosed. The toner includes a colorant for printing an image on a surface of a document, a fluorescent pigment that under normal lighting is masked by the colorant but creates a visible image on the first surface of the a substrate when irradiated by black or ultra-violet light, and a dye for forming a latent version of the image underneath a surface of a substrate. An image formed using the toner of the invention is readily verified by comparing the colorant-formed image and the dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.Type: GrantFiled: April 26, 2007Date of Patent: November 30, 2010Assignee: Troy Group, Inc.Inventors: Michael R.
