摘要

A compound of Formula (1) or a salt thereof, wherein: J is a group of the Formula (1a) wherein: R<4> and R<5> each independently is H, alkyl or alkoxy; and R<6> is H, -COOH, -SO3H or optionally substituted alkyl, aryl, alkylcarbonyl, alkylsulphonyl, alkoxycarbonyl, alkoxysulphonyl, arylcarbonyl or arylsulphonyl; A is optionally substituted phenylene or optionally substituted naphthylene; Y is naphthylene of Formula (1b) or phenylene of Formula (1c) wherein: R<2> and R<3> each independently is H, -COOH or -SO3H; Z<1> and Z<5> each independently is H, optionally substituted alkyl, optionally substituted alkoxy or -NZ<3>Z<4>; Z<2> is H, halo, -COOH, -SO3H, -OH, optionally substituted alkyl, optionally substituted alkoxy, or optionally substituted alkylthio; Z<3> is H or optionally substituted alkyl; Z<4> is H, optionally substituted alkyl or acyl; R<1> is H, optionally substituted alkyl, alkylcarbonyl, alkylsulphonyl, alkoxycarbonyl, alkoxysulphonyl, arylcarbonyl or arylsulphonyl; T and T<1> each independently is H or -SO3H; R is H, optionally substituted alkyl, optionally substituted aryl, or a group -B-NQ<1>Q<2>; B is optionally substituted C2-6-alkylene; and Q<1> and Q<2> each independently is H, optionally substituted C1-4-alkyl or Q<1> and Q<2> together with the N atom to which they are attached form an optionally substituted 5- or 6-membered ring. The compounds are useful as black colorants for ink jet printing inks.
