ABSTRACT:
The present invention provides an IR-absorbing dye of formula (I) or (II):whereinQ1, Q2, Q3and Q4are the same or different and are independently selected from a C3-20heteroarylene group comprising at least one N atom;M is selected from Si(A1)(A2), Ge(A1)(A2), Ga(A1), Mg, Al(A1), TiO, Ti(A1)(A2), ZrO, Zr(A1)(A2), VO, V(A1)(A2), Mn, Mn(A1), Fe, Fe(A1), Co, Ni, Cu, Zn, Sn, Sn(A1)(A2), Pb, Pb(A1)(A2), Pd and Pt;A1and A2are axial ligands, which may be the same or different, and are selected from —OH, halogen, —OR3, a hydrophilic ligand and/or a ligand suitable for reducing cofacial interactions;R3is a selected from C1-12alkyl, C5-12aryl, C5-12arylalkyl or Si(Rx)(Ry)(Rz); andRx, Ryand Rzmay be the same or different and are selected from C1-12alkyl, C5-12aryl, C5-12arylalkyl, C1-12alkoxy, C5-12aryloxy or C5-12arylalkoxy.Dyes of this type are especially suitable for use in netpage and Hyperlabel systems.
