Abstract

A substrate having an IR-absorbing dye disposed thereon. The IR-absorbing dye is a metal phthalocyanine dye having branched axial ligands. The branched axial ligands minimize interaction between π systems of adjacent dye molecules, and assist in reducing absorption of visible wavelengths.
