The invention relates to a novel phthalocyanine compound absorbing in the near infrared region of the spectrum with a high absorption coefficient which features high solubility in solvents, good compatibility with resins and high aging resistance, thus finding application as a near infrared ray absorbing material or a light-heat conversion material with great advantage and to a process for producing the phthalocyanine compound.
The novel phthalocyanine compound has the following general formula:
wherein R represents alkyl or alkoxyalkyl; X represents halogen, alkylthio, phenylthio which may be substituted, or naphthylthio which may be substituted; M represents a couple of hydrogen atoms, a divalent metal, or a trivalent or tetravalent metal derivative.
The near infrared ray absorbing and light-heat conversion materials containing the above phthalocyanine compound are also described.
