The present invention relates to a process for producing an opaque, transparent or translucent transaction card having multiple features, such as a holographic foil, integrated circuit chip, silver magnetic stripe with text on the magnetic stripe, opacity gradient, an invisible optically recognizable compound, a translucent signature field such that the signature on back of the card is visible from the front of the card and an active thru date on the front of the card. The invisible optically recognizable compound is preferably an infrared ink comprising an infrared phthalocyanine dye, an infrared phosphor, and a quantum dot energy transfer compound. The infrared ink can be detected by a sensor found in an ATM or card assembly line.

1. An article comprising: a thermoplastic body adapted to substantially transmit visible light;said thermoplastic body comprising a machine recognizable compound containing infrared blocking materials associated with said thermoplastic body, said infrared blocking materials comprising a mixture of a phosphor compound, and a quantum dot compound. 2. The article of claim 1, further comprising an IR-absorbing compound. 3. The article of claim 2, wherein the IR-absorbing compound comprises phthalocyanine dye. 4. The article of claim 3, wherein said IR-absorbing phthalocyanine dye is a metal core complex having halogen functional groups. 5. The article of claim 2, wherein said IR-absorbing compound is present in an amount between about 0.0001 wt. % and about 1 wt. %. 6. The article of claim 1, wherein said machine recognizable compound comprises a mixture of at least two IR-absorbing phthalocyanine dyes. 7. The article of claim 1, wherein said phosphor is selected from the group consisting of Gd203, Er203, Y203, YF3, and mixtures thereof. 8. The article of claim 1, wherein said phosphor is present in an amount between about 0.01 wt. % and about 5.0 wt. %. 9. The article of claim 1 wherein said quantum dot material contains between about C9 and about C27 ligands. 10. The article of claim 1 wherein said quantum dot material is present in an amount between about 0.0002 wt. % and about 7 wt. %. 11. The article of claim 1 wherein said machine recognizable compound is an ink printed onto at least one substrate layer. 12. The article of claim 1 wherein said machine recognizable compound further comprises a resin binder. 13. The article of claim 12 wherein said resin binder is present in an amount between about 8 wt. % to about 35 wt. %. 14. A method of making an article comprising the steps of: printing an ink over at least a portion of at least one surface of a first thermoplastic sheet, said ink comprising an IR-absorbing compound, a phosphorescent compound, a quantum dot compound, and a resin binder; andlaminating said first sheet with at least a second substantially transparent thermoplastic sheet to form a substantially transparent laminated sheet. 15. The method of claim 14 wherein said IR-absorbing compound is an IR-absorbing phthalocyanine dye. 16. The method of claim 15 wherein said IR-absorbing phthalocyanine dye is a metal core complex having halogen functional groups. 17. The method of claim 14 wherein said IR-absorbing compound is present in said ink in an amount of between about 0.0001 wt. % and about 1 wt. %. 18. The method of claim 14 wherein said ink comprises a mixture of at least two IR-absorbing phthalocyanine dyes. 19. The method of claim 14 wherein said phosphorescent compound is selected from the group consisting of Gd203, Er203, Y203, YF3, and mixtures thereof. 20. The method of claim 14 wherein said quantum dot compound contains between about C9 and about C27 ligands.
