Abstract
Abstract PCT No. PCT/JP97/03637 Sec. 371 Date May 20, 1998 Sec. 102(e) Date May 20, 1998 PCT Filed Oct. 9, 1997 PCT Pub. No. WO98/16587 PCT Pub. Date Apr. 23, 1998A monoazo compound synthesized using 2-hydroxynaphthalene-3,6-dicarboxylic acid (or salt thereof), an amide, an ureide or an ester thereof as a coupler is novel, and is superior in water resistance, chemical resistance and solvent resistance. The present invention provides such a novel azo compound and a process for producing the same.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
237 words
An azo compound represented by the following general formula I: ##STR88## wherein Y represents --(CONH)n--X or --COR; Y' represents --(CONH)n--X' or --COR'; (X and X' may be the same or different and represent an optionally substituted aromatic group, or an optionally substituted heterocyclic group having a conjugated double bond); R and R' may be the same or different and represent a hydroxyl group, an optionally branched alkoxy group having 1 to 6 carbon atoms, a benzyloxy group, a phenyloxy group or a phenacyloxy group (provided that an acceptable salt may be formed when any one of R and R' is a hydroxyl group); n represents an integer of 1 or 2; R 2 represents a hydrogen atom, an optionally branched alkyl group having 1 to 6 carbon atoms, an acyl group having 1 to 6 carbon atoms, or a phenylalkyl group; Q represents an optionally branched alkyl group having 1 to 6 carbon atoms, an optionally branched alkoxyl group having 1 to 6 carbon atoms, a halogen atom, a nitro group or a nitroso group; m represents an integer of 0 to 3 (when m is 1, Q may be combined with any one of two condensed rings and, when m is 2 or 3, Q may be combined with one or both condensed rings or may be combined together with two condensed rings to form a ring); and Z represents an optionally substituted monovalent aromatic group.
