ABSTRACT:
The present invention provides an IR-absorbing dye of formula (I) or (II)whereinR10, R13, R20, R23, R30, R33, R40and R43are independently selected from a C1-12alkyl group bearing a hydrophilic or hydrophilizable group;R11, R12, R21, R22, R31, R32, R41and R42are independently selected from H or a C1-30hydrocarbyl group, or each of R11/R12, R21/R22, R31/R32, and R41/R42are together joined to form a C3-30hydrocarbylene group;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 intermolecular 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.
