Abstract (en)

[origin: WO0165529A1] A security article, such as a promotional game mechanic, lottery ticket, event ticket or videocassette, comprises a first element bearing information applied in an initially colorless substance (2) contained in microcapsules, and a second element bearing a second substance (4). For example, the first substance (2) can comprise an initially colorless liquid color former dispersed into an ink, and the second substance (4) can comprise a dispersion of a developer for the color former. The first and second elements are placeable together so as to break the microcapsules and reveal the information by a reaction of the first and second substances (2, 4).
