摘要:
The present invention relates to a porphyrazine coloring matter represented by the following formula (1) or a salt thereof [wherein, the rings A, B, C and D shown by broken lines each independently represent a 6-membered ring having aromaticity, at least 1.0 of said rings A to D is a benzene ring and at least 0.5 of them is a nitrogen-containing heteroaromatic ring, when shown as an average value; E represents an alkylene group; X and Y are each independently an anilino group having 1 to 3 carboxy groups; and b is 0 to 3.4, c is 0.1 to 3.5, and the sum of b and c is 1.0 to 3.5, when shown as an average value]. The present invention can provide a porphyrazine coloring matter suitable for inkjet recording, which has characteristics of having a good hue as cyan ink, excellent fastnesses, in particular, extremely excellent water fastness when printed on plain paper, and high solubility in water or a water-soluble organic solvent.
