Disclosed are novel naphthalocyanine compounds which strongly absorb light of the near infrared region and which are chemically stable and highly soluble to an organic solvent. The naphthalocyanine compounds are represented by the following formula [1];
wherein X represents
( wherein R¹ and R² respectively represent a hydroxyl group, an alkyl group, an aryl group or an alkoxy group ) and M represents 2H, a metal atom, a metal oxide residue or a metal chloride residue. The present invention also provides a process for producing the naphthalocyanine compounds, intermediates thereof and a process for producing the intermediates.
