Process for making and detecting anti-counterfeit paper

Claim 1

A method of producing a radiation light source detectable, anti-counterfeit paper, wherein said method is comprised of the steps of: dissolving a soluble fluorescent dye in a solvent; dewatering wood fibers having lumens to a solids content of up to 50% solids; mixing said dissolved fluorescent dye with said dewatered wood fibers such that said fluorescent dye is loaded into said lumens of said fibers; cleaning said loaded wood fibers to substantially remove any excess fluorescent dye located on the outside of said wood fiber lumens; sealing said fluorescent dye substantially inside said lumens of said wood fibers; removing said fluorescent dye loaded wood fibers; drying said loaded wood fibers; incorporating said cleaned, lumen loaded wood fibers into a papermaking pulp furnish at a concentration of Z 2 of said total furnish, where Z 2 (ppm)=concentration of lumen loaded fibers in furnish= ##EQU3## where Z 1 =amount of lumen loaded fibers in furnish in lbs/ton of fiber wherein said cleaned, lumen loaded wood fibers are incorporated into said furnish at a concentration of between at least one parts per billion up to 25%; forming said lumen loaded furnish into an anti-counterfeit paper; and wherein said fluorescent dye in said lumen loaded fibers can be detected by employing a radiation light source.

Claim 2

A method of producing a radiation light source detectable, anti-counterfeit paper, wherein said method is comprised of the steps of: dissolving a soluble fluorescent dye in a solvent; dewatering wood fibers having lumens to a solids content of up to 50% solids; mixing said dissolved fluorescent dye with said dewatered wood fibers such that said fluorescent dye is loaded into said lumens of said fibers; cleaning said loaded wood fibers to substantially remove any excess fluorescent dye located on the outside of said wood fiber lumens; sealing said fluorescent dye substantially inside said lumens of said wood fibers; removing said fluorescent dye loaded wood fibers; drying said loaded wood fibers; incorporating said cleaned, lumen loaded wood fibers into a papermaking pulp furnish at a concentration of Z 2 of said total furnish, where Z 2 (ppm)=concentration of lumen loaded fibers in furnish= ##EQU3## where Z 1 =amount of lumen loaded fibers in furnish in lbs/ton of fiber wherein said cleaned, lumen loaded wood fibers are incorporated into said furnish at a concentration of between at least one parts per billion up to 25%; forming said lumen loaded furnish into an anti-counterfeit paper; and wherein said fluorescent dye in said lumen loaded fibers can be detected by employing a radiation light source.
