Abstract

An inkjet ink comprising an IR-absorbing dye of formula (A):

wherein

• M is selected from the group consisting of: 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;
• A¹ and A² are axial ligands, which may be the same or different, and are selected from the group consisting of: —OH, halogen and —OR³;
• R¹ and R² may be the same or different and are selected from the group consisting of: hydrogen, hydroxyl, C_1-12 alkyl, C_1-12 alkoxy, amino, C_1-12 alkylamino, di(C_1-12 alkyl)amino, halogen, cyano, thiol, C_1-12 alkylthio, nitro, carboxy, C_1-12 alkylcarbonyl, C_1-12 alkoxycarbonyl, C_1-12 alkylcarbonyloxy and C_1-12 alkylcarbonylamino;
• R³ is a selected from the group consisting of: C_1-12 alkyl, C_5-12 aryl, C_5-12 arylalkyl and Si(R^x)(R^y)(R^z);
• R^x, R^y and R^z may be the same or different and are selected from C_1-12 alkyl, C_5-12 aryl, C_5-12 arylalkyl, C_1-12 alkoxy, C_5-12 aryloxy or C_5-12 arylalkoxy;
• W is —SO₃H or a water-soluble salt thereof; and
• each m is independent selected from 0, 1 or 2.
