Abstract

A method of initiating a requested action in a computer system via a printed substrate. The substrate contains human-readable information and machine-readable coded data. The method includes the steps of: positioning a sensing device in an operative position relative to the substrate; sensing the coded data; generating indicating data in the sensing device using the sensed coded data; and sending the indicating data to the computer system. The coded data comprises a phthalocyanine salt comprising one or more sulfonate groups. A counterion of at least one sulfonate group is an ammonium cation comprising at least 20 carbon atoms.

Claims

1. A method of initiating a requested action in a computer system via a printed substrate, the substrate containing human-readable information and machine-readable coded data, the method including the steps of:

positioning a sensing device in an operative position relative to the substrate;

sensing at least some of the coded data;

generating indicating data in the sensing device using at least some of the sensed coded data, said indicating data enabling the computer to identify the requested action; and

sending the indicating data to the computer system,

wherein said coded data comprises a phthalocyanine salt comprising one or more sulfonate groups, wherein a counterion of at least one sulfonate group is an ammonium cation comprising at least 20 carbon atoms.

2. The method of claim 1, wherein said coded data is printed with a solvent-based or oil-based ink comprising the phthalocyanine salt defined in claim 1.

3. The method of claim 1, wherein said substrate is printed by an analog printing process.

4. The method of claim 1, wherein said substrate is a printed page.

5. The method of claim 1, wherein said substrate is a label or packaging for a product item.

6. The method of claim 1, wherein said ammonium cation comprises at least one group C_6-30 alkyl group or at least one C_6-30 benzylalkyl group.

7. The method of claim 1, wherein said phthalocyanine salt comprises a plurality of sulfonate groups.

8. The method of claim 1, wherein said phthalocyanine salt is IR-absorbing phthalocyanine.

9. The method of claim 1, wherein said phthalocyanine salt is a naphthalocyanine salt.

10. The method of claim 1, wherein said ammonium cation is of formula:

N(R^m)(Rⁿ)(R^s)(R^t), wherein;

each of R^m, Rⁿ, R^s and R^t is independently selected from the group consisting of;

C_1-30 alkyl, C_5-12 aryl and C_5-30 arylalkyl;

or

R^m and Rⁿ are together joined to form a C_5-10 heterocycloalkyl group, with R^s and R^t being independently selected from the group consisting of;

C_1-30 alkyl, C_5-12 aryl and C_5-30 arylalkyl;

or

R^m, Rⁿ and R^s are together joined to form a C_5-10 heteroaryl group, with R^t being independently selected from the group consisting of;

C_1-30 alkyl, C_5-12 aryl and C_5-30 arylalkyl.

11. The method of claim 10, wherein at least one of R^m, Rⁿ, R^s and R^t comprises 10 or more carbon atoms.

12. The method of claim 10, wherein at least two of R^m, Rⁿ, R^s and R^t comprise 6 or more carbon atoms.

14. The method of claim 10, wherein each of R^m, Rⁿ, R^s and R^t is independently selected from C_1-30 alkyl.

15. The method of claim 10, wherein said ammonium cation is of formula:

16. The method of claim 1, wherein said phthalocyanine salt is of formula (Ia):

17. The method of claim 1, wherein said phthalocyanine salt is of formula (I):

13. The phthalocyanine salt of claim 0, wherein at least three of R^m, Rⁿ, R^s and R^t comprise 6 or more carbon atoms.
