Patent ID: 8293148

Claim:
An azo pigment represented by the following general formula (2), a tautomer, salt, or hydrate thereof: wherein G 2 represents a hydrogen atom, an aliphatic group, an aryl group, or a heterocyclic group, R 21 represents an aryl amino group containing a total of from 6 to 14 carbon atoms, a saturated or unsaturated heterocyclic amino group containing a total of from 2 to 12 carbon atoms, an aliphatic oxy group, an aliphatic group, an aryl group, or a heterocyclic group, R 22 represents a substituent, and A 2 represents any one of the following general formulae (A-1) to (A-34), m represents an integer of from 0 to 5, n represents an integer of from 1 to 4 and, when n=2, the general formula (2) represents a dimer formed through R 21 , R 22 , G 2 , or A 2 and, when n=3, the general formula represents a trimer formed through R 21 , R 22 , G 2 , or A 2 and, when n=4, the general formula represents a tetramer formed through R 21 , R 22 , G 2 , or A 2 : wherein R 51 to R 58 each represents a hydrogen atom or a substituent, adjacent substituents may be connected to each other to form a 5- or 6-membered ring, and * shows the point of attachment to the azo group in the general formula (2).
