摘要:
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.
