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.

Battery separator structures

A method for producing a printing ink containing microcapsules which is suitable for application from an offset printing tower which comprises preparing a capsule slurry containing at least 45% by weight total solids and mixing the slurry under high shear with a printing ink vehicle containing not more than 15% by weight oil.
