PROBLEM TO BE SOLVED: To obtain the subject compound having a strong absorption peak in the near infrared region of electromagnetic spectrum and useful for various electronic devices. SOLUTION: This phthalocyanine compound is expressed by the formula I (Mk Pc is a phthalocyanine nucleus of the formula II (M is a metal, a halogeno- metal group, an oxy-metal group or H; (k) is the reciprocal of a half of the atomic valence of M; R is a 1,2-arylene; Y is O or S; R<1> is a hydrocarbyl; Z is a halogen or H; A is H, a metal or ammonium; (x) is 1-8; (y) is 0-14; (m) is 0-14; (n) is 0-32; etc.). The compound of the formula I can be produced by reacting a properly substituted phthalonitrile with a metal or a metal salt at a high temperature in the presence or absence of an inert solvent and/or a catalyst and optionally sulfonating the reaction product. The compound can be used in printed currency, check, ink-jet print, laser thermal print, flash fusion of toner, storage of optical data and charge-generation substance for laser thermal print. |
