摘要： 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.

摘要： Disclosed is a porphyrazine dye represented by the formula (1) below which is suitable for inkjet recording. The porphyrazine dye has good hue as a cyan ink, while being excellent in light resistance, ozone resistance and moisture resistance. In addition, the porphyrazine dye does not cause bronzing. (1) [In the formula, A, B, C and D independently represent a six-membered aromatic ring, with at least one of them being a benzene ring and at least one of them being a nitrogen-containing heterocyclic aromatic ring; E represents an alkylene; X and Y independently represent a substituted or unsubstituted anilino group or a substituted or unsubstituted naphthylamino group; and b represents a number from 0 to 2.9, c represents a number from 0.1 to 3 with the sum of b and c being from 1 to 3.]
