摘要： In order to provide grease, oil and wax resistance to a paper substrate, a coating containing a binder, a filler material and calcium carbonate is used. The coating of the invention is essentially free from fluorocarbons, which are considered harmful to human and animal populations, and surfactants and other chemicals which may alter the color of the coated paper. The coated paper has a GE brightness level between approximately 50 and approximately 90, while providing superior grease, oil and wax resistance.

摘要： A security stock material for use in lottery tickets or other instruments where prevention of the viewing of indicia on the lottery ticket is achieved despite tampering to make the stock material translucent by chemical or other means. A method of making the stock material by combining natural brown kraft linerboard with bleached fibers on one side and a black ink or black coating on the other side is also disclosed.
