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.
本发明涉及由下式(1)表示的卟吩
着色剂或其盐:
[其中,环 A 至 D 独立地为苯环或含氮杂芳环,含氮杂芳环的数目大于 0.00 且小于 1.00 为平均值,其余为苯环,E 为亚烷基,X 和 Y 为磺取代
苯胺基等,b 为 0.00 或以上且小于 3.90 为平均值,c 为 0.10 或以上且小于 4.00 为平均值,b 和 c 之和大于 3.00 且小于 4.00 为平均值]。含有本发明的卟吩着色物质或其盐的墨
水组合物是一种墨
水组合物,其色调更接近青色墨
水的标准色,在各种牢度,特别是
臭氧牢度方面表现出色,并能提供具有高印刷密度的记录图像,从而具有良好的平衡性,此外,它还适用于喷墨记录。
