摘要：The invention relates to a novel phthalocyanine compound absorbing in thenear infrared region of the spectrum with a high absorption coefficient which featureshigh solubility in solvents, good compatibility with resins and high aging resistance, thusfinding application as a near infrared ray absorbing material or a light-heat conversionmaterial with great advantage and to a process for producing the phthalocyaninecompound. The novel phthalocyanine compound has the following general formula:##STR1## wherein R represents alkyl or alkoxyalkyl; X represents halogen, alkylthio,phenylthio which may be substituted, or naphthylthio which may be substituted; Mrepresents a couple of hydrogen atoms, a divalent metal, or a trivalent or tetravalentmetal derivative. The near infrared ray absorbing and light- heat conversion materialscontaining the above phthalocyanine compound are also described.
