Document Type and Number:
WIPO Patent Application WO/2019/189211
Kind Code:
A1
Abstract:
The present invention relates to a compound which is represented by general formula (1).
(In formula (1), each of R1-R4 moieties independently represents -H, -SO3
-, -NO2 or the like, and adjacent moieties of the R1-R4 moieties may be combined with each other to form a ring; M represents a Cr atom or the like; X represents a non-chromophoric cation; k represents an integer of 1-8; Y represents -O- or the like; and Z represents a group that is represented by one of general formulae (2a)-(2k).) (In general formulae (2a)-(2k), each of R5-R47 moieties independently represents -H, -CN, -COOH, an optionally substituted linear or branched alkyl group having 1-20 carbon atoms, an optionally substituted aromatic hydrocarbon group having 6-30 carbon atoms, or the like; each of R48-R51 moieties independently represents -H or -SO3
-; A represents an oxygen atom or the like; *1 represents a bonding hand to be bonded with a nitrogen atom; and *2 represents a bonding hand to be bonded with an oxygen atom.)
