    • The present invention relates to a porphyrazine coloring matter represented by the following formula (1) or a salt thereof; wherein, each of the rings A to D independently represents a benzene ring or a 6-membered nitrogen-containing heteroaromatic ring, at least one or more thereof is a benzene ring, at least one of the rest is a nitrogen-containing heteroaromatic ring, E represents alkylene, X is an anilino group having a substituent and the like, Y represents an amino group; a hydroxy group; a mono- or di-alkylamino group or a nitrogen-containing heterocyclic group which may have a substituent, excepting for the combination in which Y is an amino group or a hydroxy group and X is a substituted anilino group, b is 0 to 2.9, c is 0.1 to 3, and the sum of b and c is 1 to 3. According to the present invention, a porphyrazine coloring matter suitable for inkjet recording which has a good hue as a cyan ink, is excellent in light fastness, ozone fastness and moisture fastness, and causes no bronze phenomenon can be provided.
