    Abstract: An improved scratch card instant lottery ticket includes micro-encapsulated chemical reactants which, when released, irreversibly form one of a visual color change or a fluorescence signature at a location of the card. Both the visual color change and fluorescence signature indicate that the location has been played. Scratch cards are also marked to indicate that they have been read. Cards are marked by either automatically activating chemical reactants to form a visual color and a fluorescence signature, heating a thermofluorescent material to alter a fluorescence signature, or applying a heat-responsive material to the scratch card in such that when the identification code is read, an altered material is detected. Also taught are a method and apparatus for evaluating the scratch card to determine which locations on the card have been played. The evaluation method includes the steps of: (A) directing over at least two angles a beam of light emitted from a light source to impinge on a location of the card; (B) detecting for each of the at least two angles a component of the beam of light as it leaves the location; (C) measuring scattering angles for the location from the components detected leaving the location over the at least two angles; and (D) comparing the scattering angles of the location to a predetermined threshold, and when the angles exceed the threshold identifying the location as unplayed.

    Abstract: There is disclosed a method for the time-delayed defacement of all or part of a printed work, such as a time-dependent coupon. Such method comprises applying opaque print onto a substrate and applying an opacity-labile composition of lesser nascent opacity than the visible print onto the substrate in such a manner that a change in the opacity of the opacity-labile composition causes a time-delayed defacement of the printed substrate.

    Abstract: An original document includes alphanumeric characters defined by an overprinted reflective layer formed on a complex patterned region, and having graphic or font size, shape and type coordinated to the particular patterns in the patterned region. The coordination of the overprinted reflective layer with the patterned region is such that if the document is electronically scanned or duplicated by xerographic photocopying, the pattern will at least partially obscure the alphanumeric characters so that they can only be read with difficulty, thereby camouflaging the text.
