PROBLEM TO BE SOLVED: To provide a new phthalocyanine compound, an ink used for ink jet recording and giving an image excellent in color hue and having high fastnesses to light and ozone gas, an ink jet recording method, colored compositions used for an ink sheet for thermal recording, a color toner for electrophotography and a color filter for an image pickup device, and a method for enhancing the resistance of an image to an oxidizing environment such as an atmosphere of ozone. SOLUTION: The phthalocyanine compound is represented by general formula 1 (wherein R1 to R8 are each H, halogen or the like; and W1 to W4 are each any one of R1 to R8 , or a sulfonylsulfamoyl group, or an acylsulfamoyl group, provided that one or more of W1 to W4 comprise groups having both an electron attracting group with a Hammett substituent constant of 0.20 or higher and one or more ionic hydrophilic groups) and has an association material absorption stronger than a monomer absorption on the spectral absorption curve. The colored compositions contain the phthalocyanine compound. |
