Abstract

Provided is an azo pigment having excellent coloring characteristics such as high tinctorial strength and hue and having excellent durability such as high resistance to light and ozone, a pigment dispersion containing the azo pigment, and a coloring composition. An azo pigment represented by the following general formula (1), a tautomer of the azo pigment, and a salt or a hydrate thereof: (In the general formula (1), G0 and G1 each independently represents a non-metal atomic group which can form a 5- or 6-membered heterocyclic ring wherein each heterocyclic ring may be unsubstituted or may have a substituent; each heterocyclic ring may be a monocyclic ring or a condensed ring; X represents a hetero atom; n represents an integer of 1 to 4; when n=2, the compound of formula (1) represents a dimer formed via A or a heterocyclic group represented by G0 or G1; when n=3, the compound of formula (1) represents a trimer formed via A and/or a heterocyclic group represented by G0 or G1; when n=4, the compound of formula (1) represents a tetramer formed via A and/or a heterocyclic group represented by G0 or G1; A represents any one selected from the group of the specific substituents.)

Dependent claims

An azo pigment represented by the following general formula (1), a tautomer of the azo pigment, and a salt or a hydrate thereof:

(In the general formula (1), G0 and G1 each independently represents a non-metal atomic group which can form a 5- or 6-membered heterocyclic ring wherein each heterocyclic ring may be unsubstituted or may have a substituent;
each heterocyclic ring may be a monocyclic ring or a condensed ring;
X represents a hetero atom;
n represents an integer of 1 to 4;
when n=2, the compound of formula (1) represents a dimer formed via A or a heterocyclic group represented by G0 or G1;
when n=3, the compound of formula (1) represents a trimer formed via A and/or a heterocyclic group represented by G0 or G1;
when n=4, the compound of formula (1) represents a tetramer formed via A and/or a heterocyclic group represented by G0 or G1;
A represents any one selected from the group of substituents represented by (A-1) to (A-44) in the following general formula (2);
* represents the binding site to the N atom in the general formula (1).)
(In the group of substituents (A-1) to (A-44) represented by the general formula (2), R11 to R112 each independently represents a hydrogen atom or a substituent;
Q1 in (A-12), Q2 in (A-41), Q3 in (A-42) and Q4 in (A-43) each represents a non-metal atomic group necessary for forming a 5- to 8-membered heterocyclic group with a hetero atom;
Q5 in (A-44) represents a non-metal atomic group necessary for forming a 5- to 8-membered hydrocarbon ring;
R represents a substituent;
r represents an integer of 0 to 4;
When substituent R is plural, each R may be the same as or different from every other R.)
