Abstract:
A method of printing an IR-absorbing dye onto a substrate whilst minimizing visible coloration of the substrate. The method comprises: (i) preselecting the dye from a metal-cyanine of formula (I): Q1, Q2, Q3 and Q4 are the same or different and are independently selected from a C3-20 arylene group or a C3-20 heteroarylene group; M is selected from Si(A1)(A2), Ge(A1)(A2), Ga(A1), Al(A1), Mn(A1), Fe(A1), Sn(A1)(A2), Pb(A1)(A2); A1 and A2 may be the same or different and are axial ligands comprising a group for reducing {tilde over (□)}-□ interactions between adjacent dye molecules; and (ii) printing the dye onto the substrate.
