The present invention relates to chromophoric compositions, in particular to compositions containing as chromophore an IR absorbing compound and specific stabilizing compounds which prevent the oxidative degradation of the chromophore. Further aspects of the invention are a printing ink containing an IR absorbing chromophore and said specific stabilizing compounds, a security document comprising a substrate and the hardened printing ink and the use of the specific compounds as stabilizers for chromophores in an oxidative environment.
