Claims4
A bis-azo/hydrazone pigment of the formula (III)
- wherein:
- A is a substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl radical;
- R′ is hydrogen, alkyl, aralkyl, aryl or heteroaryl;
- Z is hydrogen, CO—X—B, CN or COCH3;
- B is an aliphatic, carbocyclic or heterocyclic radical, an aryl radical or a heteroaryl radical;
- Q is a divalent aliphatic, carbocyclic or heterocyclic radical, a substituted or unsubstituted aryl radical, a divalent substituted or unsubstituted biphenyl radical or a divalent substituted or unsubstituted heteroaryl radical, where the substituent may be halogen, alkyl or alkoxy;
- and
- X is a divalent O or NH radical.
