Abstract:
1. A method of initiating a requested action in a computer system via a printed substrate, said substrate having human-readable information and machine-readable coded data printed thereon, the coded data being indicative of a substrate identity and of a plurality of locations on the substrate, the method comprising the steps of: interacting with the substrate using an optically imaging sensing device; imaging at least some of the coded data; generating indicating data in the sensing device using the imaged coded data, said 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, thereby enabling the computer system to initiate the requested action, wherein the coded data is printed with an ink comprising an IR-absorbing naphthalocyanine dye of formula (I): wherein M is a metal group or is absent, R 1 and R 2 are independently selected from the group consisting of: hydrogen and C 1-12 alkoxy; X is selected from the group consisting of: O, S and ˜ N{tilde over (H)}; Ar 1 , Ar 2 , Ar 3 , Ar 4 , Ar 5 , Ar 6 , Ar 7 and Ar 8 are selected from the group consisting of: phenyl, naphthyl, pyridyl, furanyl, pyrollyl and thiophenyl, each of Ar 1 , Ar 2 , Ar 3 , Ar 4 , Ar 5 , Ar 6 , Ar 7 and Ar 8 being optionally substituted with 1, 2, 3, 4 or 5 groups, each group being independently selected from the group consisting of: C 1-13 alkyl, C 1-12 alkoxy, C 1-12 arylalkyl, C 1-12 arylalkoxy, ˜ (OCH 2 CH 2 ) d OR d , cyano, halogen, amino, hydroxyl, thiol, —SR v , —NR u R v , nitro, phenyl, phenoxy, ˜ CO 2 R v , ˜ C(O)R v , ˜ OCOR v , ˜ SO 2 R v , ˜ OSO 2 R v , ˜ NHC(O)R v , ˜ CONR u R v , ˜ CONR u R v , sulfonic acid, sulfonic acid salt and sulfonamide; d is an integer from 2 to 5000; R d is H, C 1-8 alkyl or C(O)C 1-8 alkyl; and R u and R v are independently selected from the group consisting of: hydrogen, C 1-12 alkyl, phenyl or phenyl-C 1-8 alkyl; and wherein at least one of Ar 1 , Ar 2 , Ar 3 , Ar 4 , Ar 5 , Ar 6 , Ar 7 and Ar 8 is substituted with a sulfonic acid or a sulfonic acid salt.
