| 20090266877 | Method Of Enabling Data Entry Using Substrate Comprising IR-Absorbing Dye - A method of enabling entry of data into a computer system via a printed substrate. The substrate has a surface containing human-readable information and machine-readable coded data. The coded data is indicative of an identity of the substrate and of a plurality of reference points on the surface. The method includes the steps of: operatively positioning a sensing device relative to the surface and sensing the coded data; generating indicating data using the sensed coded data; and sending the indicating data to a computer system. The coded data comprises an IR-absorbing dye having a nitrogen-substituted phthalocyanine. | 10-29-2009 |
| 20090284809 | Method Of Initiating Requested Action Via Substrate Printed With Naphthalocyanine Dye - A method of initiating a requested action in a computer system via a printed substrate. The substrate has human-readable information and machine-readable coded data printed thereon. The coded data is indicative of a substrate identity and of a plurality of locations on the substrate. The method comprises the steps of: (a) interacting with the substrate using an optically imaging sensing device; (b) imaging the coded data; (c) generating indicating data in the sensing device using the imaged coded data, the indicating data identifying the substrate identity and a position of the sensing device relative to the substrate; and communicating the indicating data to the computer system so that the computer system can initiate the requested action. The coded data is printed with an ink comprising an IR-absorbing naphthalocyanine dye. | 11-19-2009 |
| 20100003470 | INKJET DYES EXHIBITING REDUCED KOGATION - A salt of a sulfonated dye comprising an ammonium cation as a counterion. The ammonium cation comprises at least 3 hydroxyl groups.
