ANTHRAPYRIDONE SULPHONIC ACID COMPOUNDS, PREPARATION AND USE THEREOF

摘要

Disclosed are compounds having the structure (I) or their salts having the structure (II). In the structures (I)-(II), the substituted groups (A)p and (SO3H)n on the phenyl may be attached at ortho, meta or para positions of the phenyl ring, n is 0-2, p is 0-3; M is selected from Li+, Na+, K+, NH4 + or organic ammonium salt N+R1R2R3R4, in which R1, R2, R3 and R4 are the same or different and selected from H, C1-18alkyl, cyclohexyl, CH2CH2OH, CH(CH3)CH2OH or benzyl;when p>0,A is the same or different and selected from the following groups: H, CN, NO2, NH2, F, Cl, Br, C1-18alkyl, cyclohexyl, phenyl, benzyl, phenoxyl, C1-18alkoxyl, C1-18alkylthiol, SO2CH=CH2, SO2CH2CH2A1, NR6COR5 or NR6SO2R5. The compounds of structures (I)-(II) having excellent lightfastness, ozone resistance and at the same time excellent solubility and stability in aqueous system or aqueous organic solvent system can be used as Fuchsine.
