Patent

CA 2141982

A lottery ticket, for example of the "instant" scratch-off kind, comprises a non-opaque base paper and a coating layer or layers positioned between the base paper and win-or-lose indicia carried by the ticket. The coating is not self- supporting, so that it is not itself susceptible to fraudulent delamination, and is opaque with respect to transmitted light. Thus even if the base paper is delaminated, the win-or-lose indicia are still not discernible on viewing the ticket against a high intensity light source, since the opaque coating is still between the indicia and the light source. The desired opacity of the coating is achieved by the use of opaque pigments such as carbon black or aluminium powder or flake. The opaque coating can carry a light-coloured topcoat for enhanced printability, or a lustrous topcoat giving an attractive decorative effect.
