Abstract (en)
[origin: WO2017103777A1] A scratch-off lottery ticket and associated production method are provided wherein a primer material is applied as a dried layer to a front face of a ticket substrate, Game play indicia is printed on the primer layer in a designated game play area, and a scratch-off layer is applied over the game play indicia. The primer layer includes a particulate luminescent material homogeneously dispersed throughout, wherein the particulate luminescent material has a particle size and additive amount relative to the primer layer such that the particulate luminescent material does not add processing or material drying time to application of the primer layer. Fraudulent attempts to remove the scratch-off layer to reveal the underlying play indicia are rendered optically apparent by luminescence of the particulate luminescent material upon subsequent excitation of the play area with an excitation source.
