Abstract: The present invention relates to specific Ga-naphthalocyanine chromophores with short chain alkoxy axial substituents, 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.
