Abstract:
An azo compound having the general formula [I]: wherein Y is â€”(CONH)n-X or an optionally esterified carboxyl group, Yâ€² is â€”(CONH)n-Xâ€² or an optionally esterified carboxyl group, (wherein X and Xâ€² are optionally substituted and/or branched saturated or unsaturated aliphatic hydrocarbon groups, optionally substituted aromatic groups, or optionally substituted heterocyclic groups having conjugated double bonds, n is an integer of 1 or 2, provided that when either Y or Yâ€² is a carboxylic group, said carboxylic group may optionally form an acceptable salt), R2 is a hydrogen atom, an optionally branched alkyl group having 1-6 carbon atoms, an acyl group having 1-6 carbon atoms or a phenyl alkyl group, Q is an optionally branched alkyl group having 1-6 carbon atoms, an optionally branched alkoxy group having 1-6 carbon atoms, a halogen atom, a sulfo group, a nitro group, a nitroso group, or an amino group, m is an integer of 0-3, provided that when m is 1, the Q may be combined with either of the two condensed rings, when m is 2 or 3, the Qs may be combined with either or both of the condensed rings, or may form a ring together with the two condensed rings, and Z is an optionally substituted monovalent aromatic group; provided that at least one of Y and Yâ€² represents a group wherein X or Xâ€² is an optionally substituted and/or branched unsaturated or saturated aliphatic hydrocarbon group.
