Patent number: 9221989Abstract: A tamper evident document, a process of preparing the tamper evident document, and a tamper evident ink. The tamper evident document includes a paper substrate having a face for providing information, and a tamper evident ink applied on the face of the paper substrate. The tamper evident ink includes (i) microcapsules having a cross-linked polymer shell and a core surrounded by the shell; and (ii) developer particles. The cores of the microcapsules include at least one color former dissolved in a carrier oil. If information on the tamper evident document is altered by force or pressure (e.g., by scraping with a knife), the microcapsules rupture and the color former reacts with the developer particles to provide a visual indication of tampering (e.g., appearance of color or color change) on the face of the document.Type: GrantFiled: August 28, 2013Date of Patent: December 29, 2015Assignee: P.H. Glatfelter CompanyInventors: John W. Stolarz, Jr., William N. Justice, James Gregory Lovensheimer

Patent number: 8673398Abstract: A method for treating a substrate is described. In accordance with one aspect, the method includes applying a polymer coating to a substrate, and bringing the polymer coating into contact with a heated surface in a pressure nip while the coating is still in a wet state. Optionally the polymer coating may include a crosslinkable material, and a crosslinking agent may be used to promote crosslinking. The polymer coating replicates the heated surface. A product produced in accordance with the described method is also disclosed. The product is characterized by having subsurface voids within the coating.Type: GrantFiled: May 29, 2008Date of Patent: March 18, 2014Assignee: MeadWestvaco CorporationInventors: Gary P. Fugitt, Scott E. Ginther, John W. Stolarz, Robert W. Carlson, Stanley H. McGrew, Jr., Steven P. Metzler, Terrell J. Green
