The present invention relates to compounds of the formula (I′), especially compounds of formula (I), a process for their preparation and their use as almost colourless IR absorbers, for optical filter applications, especially for plasma display panels, or for laser welding of plastics. The compounds may be used in compositions for inks, paints and plastics, especially in a wide variety of printing systems and are particularly well-suited for security applications, or for brand protection; or as marker for liquid. Compounds of formula (I′), especially compounds of formula (I), represent almost colourless IR absorbers, which exhibit high resistance against chemicals and solvents as well as good light stability and good thermal stability. Due to their unique application properties they can be advantageously employed as IR absorbers for laser writing, heat shielding, security printing, the laser-welding of plastics and as marker for liquids.
