摘要： The present invention provides an IR-absorbing naphthalocyanine dye of formula (I): wherein M is selected from Ga(A1); A1 is an axial ligand selected from OH, halogen (preferably Cl), OR3, a hydrophilic ligand and/or a ligand suitable for reducing cofacial interactions; R1 and R2 may be the same or different and are selected from hydrogen or C1-12 alkoxy (preferably C1-6 alkoxy); R3 is selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl or Si(Rx)(Ry)(Rz); and Rx, Ry and Rz may be the same or different and are selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl, C1-12 alkoxy, C5-12 aryloxy or C5-12 arylalkoxy; W is a hydrophilic group; n1 is 0, 1, 2 or 3; n2 is 0, 1, 2 or 3; n3 is 0, 1, 2 or 3; n4 is 0, 1, 2 or 3; provided that at least one of n1, n2, n3 or n4 is greater than 0. Dyes of this type are especially suitable for use in netpage and HyperlabelTM systems.

摘要： There is provided an aqueous formulation comprising an IR-absorbing naphthalocyanine dye of formula (II): or a salt form thereof, wherein: M is Ga(A1); A1 is an axial ligand selected from -OH, halogen, -OR3, -OC(O)R4 or -O(CH2CH2O)eR6 wherein e is an integer from 2 to 10 and R6 is H, C1-8 alkyl or C(O)C1-8 alkyl; R1 and R2 may be the same or different and are selected from hydrogen or C1-2 alkoxy; R3 is selected from C1-2 alkyl, C5-I2 aryl, C5-12 arylalkyl or Si(Rx)(Ry)(Rz); R4 is selected from C1-12 alkyl, C5-12 aryl or C5-12 arylalkyl; and Rx, Ry and Rz may be the same or different and are selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl, C1-12 alkoxy, C1-12 aryloxy or C5-12 arylalkoxy. The formulation has a pH in the range of 3,5 to 7 and is particularly suitable for use as an IR- absorbing inkjet ink, providing compatibility with known CMYK, inks together with an optimally red-shifted λmax
