Claim:
A porphyrazine coloring matter represented by the following formula (1) or a salt thereof, wherein, rings A to D represented by dotted lines each independently represent a benzene ring or a six-membered nitrogen-containing heteroaromatic ring that has been ring condensed to a porphyrazine ring; and the number of nitrogen-containing heteroaromatic rings is more than 0.00 and no more than 3.00 in terms of mean value, and the rest represents a benzene ring; E represents a C2-C12 alkylene; X represents a sulfoanilino group, a carboxyanilino group, a phosphonoanilino group, a sulfonaphthylamino group, a carboxynaphthylamino group or a phosphononaphthylamino group which may have one or at least two types of substituent(s) selected from the group consisting of a sulfo group, a carboxy group, a phosphorate group, a sulfamoyl group, a carbamoyl group, a hydroxy group, a C1-C6 alkoxy group, an amino group, a mono-C1-C4 alkylamino group, a di-C1-C4 alkylamino group, a mono-C6-C10 arylamino group, a di-C6-C10 arylamino group, a C1-C3 alkylcarbonylamino group, an ureido group, a C1-C6 alkyl group, a nitro group, a cyano group, a halogen atom, a C1-C6 alkylsulfonyl group, and a C1-C6 alkylthio group; R represents a hydrogen atom, a sulfo group, a carboxy group, a phosphorate group, a sulfamoyl group, a carbamoyl group, a hydroxy group, a C1-C6 alkoxy group, an amino group, a mono-C1-C6 alkylamino group, a di-C1-C6 alkylamino group, a mono-C6-C10 arylamino group, a di-C6-C10 arylamino group, a C1-C3 alkylcarbonylamino group, an ureido group, a C1-C6 alkyl group, a nitro group, a cyano group, a halogen atom, a C1-C6 alkylsulfonyl group, or an alkylthio group; group F represents a phenyl group, or a six-membered nitrogen-containing heteroaromatic ring group; a represents an integer of 1 to 6, b is at least 0.00 and less than 3.90 in terms of mean value, c is at least 0.10 and less than 4.00 in terms of mean value, and the sum of b and c is at least 1.00 and less than 4.00 in terms of mean value.
