The present invention relates to a porphyrazine coloring matter represented by the following formula (1):(wherein, A, B, C and D independently represent a 6-membered ring having aromaticity, at least one or more of them are benzene rings and at least one or more of them contain nitrogen-containing heteroaromatic rings; E represents alkylene, X is a substituted anilino group and have at least one or more of sulfo group, carboxy group and phosphono group as a substituent, Y represents a hydroxy group or an amino group, b is respectively 0 to 2.9, c is 0.1 to 3, and the sum of b and c is 1 to 3) in free acid form, which is suitable for inkjet recording because it has good hue as a cyan ink, is excellent in light fastness, ozone fastness and moisture fastness, and does not cause bronzing phenomenon.

Disclosed are an ink composition containing at least one of a porphyrazine compound or a salt thereof and an aromatic compound having a sulfo group or a salt thereof, an ink jet recording method using the ink composition and a recorded material recorded by the recording method.

Provided is a porphyrazine dye suitable for use in ink-jet recording, the porphyrazine dye giving a cyan ink with a satisfactory hue, having various excellent fastness properties, in particular, ozone resistance, and attaining a high color density. Also provided is an ink composition containing the dye. The porphyrazine dye is a porphyrazine dye represented by formula (1) or a salt thereof. In formula (1), rings A to D each independently represents a benzene ring, a nitrogenous heteroaromatic ring, etc.; E represents an alkylene; X represents sulfoanilino, etc.; R represents a hydrogen atom, sulfo, carboxy, etc.; group F represents phenyl, a nitrogenous heteroaromatic ring, etc.; a is an integer of 1-6; b is 0.00-3.90, excluding 3.90, on average; c is 0.10-4.00, excluding 4.00, on average; and the sum of b and c is 1.00-4.00, excluding 4.00, on average.

A porphyrazine dye represented by formula (1), and a dye dispersing composition containing the same. [In formula (1): M represents a metal atom, a metal oxide, a metal hydroxide, a metal halide, or a hydrogen atom; rings A, B, C and D each independently represent formulas (2)-(8) (except where A, B, and C are all (8)); X represents a lower alkyl group, a lower alkoxy group, an amino group, a nitro group, a halogen group, a hydroxy group, a carboxy group, a sulfonic acid group, or a sulfonamide group; Y represents a divalent crosslinking group; Z represents a sulfonic acid group, a carboxy group, a residue from which at least one hydrogen above a nitrogen atom on a primary-secondary amino group has been removed, or a residue from which at least one hydrogen above a nitrogen atom in a heterocyclic ring containing nitrogen has been removed; a and b are each average values; a and b are each 0-12; and the sum of a and b is 0-12].

The present invention relates to a porphyrazine coloring matter or a salt thereof represented by the following formula (1):[wherein, the rings A to D are independently a benzene ring or a nitrogen-containing heteroaromatic ring, the number of the nitrogen-containing heteroaromatic ring is more than 0.00 and less than 1.00 as an average value, the rest are benzene rings, E is alkylene, X and Y are a sulfo-substituted anilino group and the like, b is 0.00 or more and less than 3.90 as an average value, c is 0.10 or more and less than 4.00 as an average value, and the sum of b and c is more than 3.00 and less than 4.00 as an average value]. The ink composition containing the porphyrazine coloring matter of the present invention or a salt thereof is an ink composition which has a hue closer to the standard color as a cyan ink, is excellent in various fastnesses, particularly in ozone fastness, and can provide recorded images having a high print density and thus having a good balance, and further it is suitable for inkjet recording.
