ABSTRACT:
The invention relates to a new lottery ticket paper for the manufacture of different kinds of lottery tickets, especially of the "instant lottery ticket" type, and a method of manufacturing said tickets. The lottery ticket paper is characterized in that it comprises a coloured, opaque base paper coated on both sides with a composition comprising at least one pigment, a filler, a binder solution, and optionally viscosity regulating agents and some kind of security element. The lottery ticket paper is protected against see-through and various kinds of forgery. It is an environmentally pleasing, nonexpensive and from the production-technical point of view suitable alternative to existing foil-laminated lottery ticket papers.
