ABSTRACT:
A novel lottery ticket comprising a blush-type coating which coating is characterized by susceptibility to a change in appearance when exposed to either (a) any of a wide spectrum of organic solvents or (b) an elevated temperature. Such susceptibility reveals that solvent or thermal techniques have been used in tampering with the ticket or a pouch package in which the ticket is held. Such tampering is often the result of an illicit attempt to obtain information about the indicia printed on the ticket.
