    摘要: There is provided an IR-absorbing naphthalocyanine dye of formula (I): wherein M is Ga(A1); A1 is an axial ligand selected from -OH, halogen, -OR3, -OC(O)R4 or -O(CH2CH2O)OR6 wherein e is an integer from 2 to 10 and R6 is H, C1-8 aIkyI or C(O)C1-8 alkyl; R1 and R2 may be the some or different and are selected from hydrogen or C1-12 alkoxy; R3 is selected from C1-12 alkyl, C5-12 aryl, C5-12 arylalkyl or Si(Rx)(RY)(RZ); R4 is selected from C1-12 alkyl, C5-12 aryl or C5-12 arylalkyl; 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-I2 aryloxy or C5-12 arylakoxy, and each B is independently selected from a base, wherein BH+ has a pKa of between 4 and 9. The dye is particularly suitable for use in IR-absorbing inkjet inks, providing compatibility with known CMYK inks together with an optimally red-shifted λmax.
