| abstract | Compounds of Formula (6): wherein: L<SP>3</SP> is L<SP>1</SP> or a labile atom or group; L<SP>4</SP> is L<SP>2</SP> or a labile atom or group; A is N, C-CI, C-CN or C-NO 2 ; R<SP>1</SP> is H or optionally substituted alkyl; G is sulpho, carboxy, optionally substituted alkyl, optionally substituted alkoxy, -CF 3 or -PO 3 H 2 ; L<SP>1</SP> and L<SP>2</SP> are each independently -SR<SP>2</SP>, -OR<SP>3</SP> or -NR<SP>4</SP>R<SP>5</SP>; R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP> and R<SP>5</SP> are each independently H, optionally substituted alkyl or aryl optionally substituted by a group other than vinyl sulphone, sulphatoethylsulphonyl or phosphonooxyethylsulphonyl; or R<SP>4</SP> and R<SP>5</SP> together with the nitrogen to which they are attached form an optionally substituted five or six membered ring; provided that at least one of L<SP>3</SP> and L<SP>4</SP> contain one or more substituents selected from carboxy, sulpho and -PO 3 H 2 , may be formulated as an ink and used in an ink jet printer cartridge for use in printing. (57) continued overleaf (57) cont Dyes of formula (6) wherein L<SP>3</SP> is L<SP>1</SP> only and L<SP>4</SP> is L<SP>2</SP> only, but wherein the proviso for L<SP>3</SP> and L<SP>4</SP> still applies, are claimed as novel compounds. An ink preferably comprises: (a) from 0.01 to 30 parts of a compound of the Formula (6); and (b) from 70 to 99.99 parts of a medium comprising a mixture of water and an organic solvent, an organic solvent free from water, or a low melting point solid; wherein all parts are by weight and the number of parts of (a)+(b)=100: |
