摘要

Azo dyes of Formula (1) have utility as dyes for ink-jet printing which comprises any suitable form of the compound: such as salt, stereoisomer, zwitterion, polymorph, complex, isotopic form, combinations thereof in the same species and mixtures thereof; where: p represents from 1 to 7 inclusive; the naphthyl moiety may be optionally substituted; R<1> comprises at least one of the following substituents, optionally substituted: H, C1-4-alkyl, NHCOC1-4 alkyl, C1-4 alkoxy, NHCOaryl, NHSO2C1-4 alkyl, NHSO2aryl, NHCONR<3>R<4> where R<3> and R<4> each independently comprises H, C1-4alkyl or aryl; R<2> comprises H, C1-4 alkyl or C1-4 alkoxy; L<1> and L<2> each independently comprises at least one of the following substituents, optionally substituted: -NH2, -NHC1-4 alkyleneOH, -SC1-4alkylene -SO3H, -NHC1-4alkyleneN(C1-4alkyl)2, -N(C1-4alkyleneOH)2, -NHC1-4alkyleneSO3H, -NHC1-4alkylene(CO2H)n where n is 1, 2 or 3, -SC1-4alkylene(CO2H)m where m is 1, 2 or 3, a moiety of Formula (2) where X represents NHC1-4alkylene or a direct link and Y represents O or NH; a moiety of Formula (3), where q represents from 1 to 7 inclusive; the naphthyl moiety may be optionally substituted; and R<5> and R<6> each independently comprises at least one of the following substituents, optionally substituted: H, C1-4-alkyl, NHCOC1-4 alkyl, C1-4 alkoxy, NHCOaryl, NHSO2C1-4 alkyl, NHSO2aryl and NHCONR<7>R<8> where R<7> and R<8> each independently comprises H, C1-4alkyl, aryl; and any other suitable labile or non-labile substituent not mentioned above; where the optional substituents herein comprise: C1-4alkyl (optionally substituted with at least one halo), C1-4alkoxy (optionally substituted with at least one halo), carboxy, sulpho, hydroxy, amino, mercapto, cyano, nitro and halo.
