Abstract
Provided are a compound represented by Formula 1, a tautomer of the compound or a salt of the compound or the tautomer, a coloring composition and a dyed article containing the compound represented by Formula 1, the tautomer of the compound, or the salt of the compound or the tautomer, and a dyeing method using the compound represented by Formula 1, the tautomer of the compound, or the salt of the compound or the tautomer. In Formula 1, X, R, Ar, n, and m1 are as defined in the specification.
Claims15
A compound represented by Formula 1, a tautomer of the compound, or a salt of the compound or the tautomer,
- in Formula 1, X— represents R1O—, R2aR2bN—, or R3S—, R1, R2a, and R2b each independently represent a hydrogen atom or an alkyl group, R3 represents an alkyl group, in a case where X— is R2aR2bN—, R2a and R2b may be the same or different from each other and R2a and R2b may be bonded to each other to form a nitrogen-containing hetero ring, R's each independently represent a substituent, n represents 0, 1, 2, or 3, in a case where n represents 2 or 3, R's may be the same or different from each other, Ar represents an aromatic hydrocarbon group or a heterocyclic group, m1 represents 1, 2, or 3, and in a case where m1 represents 2 or 3, Ar's may be the same or different from each other, provided that at least one of Ar's is a heterocyclic group.
