PAPER SUBSTRATES INCORPORATING COVERT MARKING PIGMENTS, AND PROCESSES FOR OBTAINING AND USING SAME

Paper substrates which incorporate covert marking pigments (CMPs) which are one or more infrared (IR) anti-Stokes pigments. Also, processes for incorporating such CMPs into a paper substrate other than by a printing technique, such as, for example, by using a size press or spraying, as well as proce...

Zusammenfassung:	Paper substrates which incorporate covert marking pigments (CMPs) which are one or more infrared (IR) anti-Stokes pigments. Also, processes for incorporating such CMPs into a paper substrate other than by a printing technique, such as, for example, by using a size press or spraying, as well as processes for identifying the presence of such CMPs incorporated into a paper substrate sheet with an infrared (IR) pigment sensor of, for example, a copier or printer for the purpose of adjusting the quantity of printer pigment deposited on a paper substrate sheet or to determine whether the paper substrate sheet is an authentic or counterfeit document. L'invention concerne des substrats de papier qui incorporent des pigments de marquage cachés (PMC) qui consistent en un ou plusieurs pigments infrarouges (IR) anti-Stokes. L'invention concerne également des procédés d'incorporation de tels PMC dans un substrat de papier, autrement que par une technique d'impression en utilisant, par exemple, une presse encolleuse ou une pulvérisation, ainsi que des procédés pour identifier la présence de telles PMC incorporées dans une feuille de substrat de papier avec le capteur de pigment infrarouge (IR), par exemple, d'un copieur ou d'une imprimante, dans le but d'ajuster la quantité de pigment d'impression déposée sur une feuille de substrat de papier ou de déterminer si la feuille de substrat de papier est un document authentique ou contrefait.
