Patent number: 6258746Abstract: A thermally imagable business record, such as a form, label, tag, or the like is provided which may be activated to form human and/or machine readable images as well as different colored images. The record comprises a substrate having a thermally imagable coating on substantially its entire surface which forms a first color when activated, and having a desensitized area on at least one area of its surface which may be overcoated with a thermally imagable coating capable of forming a different color upon activation than the first thermally imagable coating. The first thermally imagable coating provides images which are of machine readable quality, while the additional thermally imagable coatings provide images of a different color to designate selected areas on the form or label to a user.Type: GrantFiled: December 8, 1999Date of Patent: July 10, 2001Assignee: The Standard Register CompanyInventors: Rajendra Mehta, Gary Doll, Mark Dotson, A. Dale Lakes, Rick L. Shields

Patent number: 6019022Abstract: A combination screwdriver, scraper and prybar has a handle with an elongated shank terminating in a multi-function blade. The blade has opposed, flat, planar blade faces converging toward and joined by a distal planar end surface which intersects and is perpendicular to the longitudinal axis of the shank. The blade faces are respectfully inclined to the axis at substantially three degrees and substantially seven degrees. The shank may be square or circular in transverse cross-section and, if square, opposed sides of the shank lie in planes perpendicular to the blade faces.Type: GrantFiled: January 15, 1999Date of Patent: February 1, 2000Assignee: Snap-on Tools CompanyInventor: Mark A. Dotson

Patent number: 5984363Abstract: A thermally imagable business record such as a form, tag, label or the like is provided in which selected areas of the record may be activated to form an image upon exposure to heat. In one embodiment, at least one selected area of a substrate surface contains a thermally imagable coating of initially colorless color formers and color developers while the remaining areas of the substrate are left uncoated. The substrate may be pre-coated to provide a smooth, non-porous base coat for the thermally imagable coating, and may also include a protective coating layer to protect the subsequently printed thermal image.Type: GrantFiled: April 29, 1994Date of Patent: November 16, 1999Assignee: The Standard Register CompanyInventors: Mark Dotson, Rajendra Mehta, A. Dale Lakes

Patent number: 5912205Abstract: A security document is provided containing a color-forming composition having an insulating material therein which allows the document to be passed through heated printing devices such as laser printers without the problem of premature color development. The color-forming composition includes a mixture of a color former, a color developer, and an insulating material. In a preferred embodiment, a toner adhesion-enhancing composition containing an insulating material is applied over the color-forming composition. The security document may be used to provide an authentication feature and/or an indication of attempted alterations from the use of solvents, heat or abrasion.Type: GrantFiled: January 30, 1997Date of Patent: June 15, 1999Assignee: The Standard Register CompanyInventors: A. Dale Lakes, Mark Dotson, Rajendra Mehta

Patent number: 5888283Abstract: A direct thermal ink composition is provided which is formed from an aqueous dispersion of an initially colorless color former and an initially colorless color developer in particulate form. The direct thermal ink composition also includes a sensitizer, where the particles of the sensitizer at least partially surround the particles of the color developer, which prevents premature color development of the ink. The thermal ink preferably has a solids content of between about 40 to 60% by weight, and is substantially free of pigments and fillers.Type: GrantFiled: November 5, 1996Date of Patent: March 30, 1999Assignee: The Standard Register CompanyInventors: Rajendra Mehta, Rick L. Shields, Mark Dotson

Patent number: 5840657Abstract: A linerless continuous series of pressure sensitive adhesive labels is provided which have on one or more selected portions thereof a series of imagable coatings which may be activated to form colored images or areas. The series of labels include a web having first and second surfaces, with a series of imagable coatings of color formers and color developers on the first surface of the web. A coating of a release material overlies the imagable coatings on the first surface of the substrate, and a coating of a pressure sensitive adhesive is positioned on the second surface of the web. The series of labels are wound or stacked so that the coating of pressure sensitive adhesive contacts the release material to permit individual labels to be dispensed.Type: GrantFiled: January 31, 1997Date of Patent: November 24, 1998Assignee: The Standard Register CompanyInventors: Rajendra Mehta, David F. Laurash, Mark Dotson, A. Dale Lakes, Lawrence W. Arway

Patent number: 5698296Abstract: A security coating for business documents printed using noncontact as well as impact printing devices is provided which enhances the adhesion of toner particles and/or ink to a document substrate. Other security features may be also be added to the coating to provide a dual-function coating which also provides visible evidence of tampering, either by the application of solvents, mechanical abrasion, heat, or when pressure is applied.Type: GrantFiled: December 12, 1995Date of Patent: December 16, 1997Assignee: The Standard Register CompanyInventors: Mark Dotson, Rajendra Mehta, William F. Pinell, William M. Saluke

Patent number: 5058925Abstract: An initially colorless, chemically sensitive protective ink which can be readily printed or applied onto a document substrate and which reacts upon contact with an oxidizing agent to form a noticeable color change is provided. The protective ink, when printed onto a document, resists leaching by water for an extended period of time, both before and after contact with oxidizing agents, and provides visible evidence of any attempted tampering. The leach-resistant ink includes a colorless material which becomes colored upon contact with an oxidizing agent and a complexing agent which reacts to form a complex with the colorless material. A fixing agent which promotes insolubilization and fixing of the complex to the document substrate is also provided.Type: GrantFiled: December 13, 1989Date of Patent: October 22, 1991Assignee: The Standard Register CompanyInventor: Mark Dotson

Patent number: 5029901Abstract: A confidential information bearing article comprising a cover sheet adhered to a base sheet is provided which is capable of providing hidden confidential information to a recipient. Through the use of camouflage, obscuring, and opacifying and reflectivity increasing coatings, the paper used for the mailer becomes effectively opaque, and information printed on the inside of the article is substantially unreadable from the outside. The article includes an adhesive for securing the base sheet and cover sheet and perforations along the edges to assist the recipient in opening the article.Type: GrantFiled: February 7, 1990Date of Patent: July 9, 1991Assignee: The Standard Register CompanyInventors: Mark Dotson, William H. Mowry, William M. Saluke, A. Dale Lakes
