| titleOfInvention | Ink jet dyes based on two aliphatically linked [7-(ortho-carboxyarylazo)-8-hydroxydisulphonaphth-2-ylamino]-(dia/tria)zinyl units |
| abstract | Compounds of the Formula (1) and salts thereof: <EMI ID=1.1 HE=59 WI=124 LX=427 LY=525 TI=CF> <PC>wherein:<BR> <DL TSIZE=18> <DT>each A<DD>independently is N, C-Cl, C-CN or C-NO<SB>2</SB>; <DT>each Ar<DD>independently is a substituted aryl group carrying a -COOH group ortho to the azo (-N=N-) group; <DT>L<DD>is an aliphatic group carrying a -COOH, -SO<SB>3</SB>H or -PO<SB>3</SB>H<SB>2</SB> group; <DT>each Z<DD>independently is -SR<SP>2</SP>, -OR<SP>3</SP>, -NR<SP>4</SP>R<SP>5</SP> or a labile atom or group; <DT>each X<DD>independently is -S-, -O- or -NR<SP>1</SP>-; <DT>each R<SP>1</SP><DD>independently is H or optionally substituted alkyl; and <DT>R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP> and R<SP>5</SP><DD>are independently H, optionally substituted alkyl, optionally substituted aryl or optionally substituted aralkyl; or <DT>R<SP>4</SP> and R<SP>5</SP><DD>together with the nitrogen to which they are attached form an optionally substituted five or six membered ring, are magenta dyes that are highly soluble in aqueous media, have good light-fastness and may be incorporated into inks for ink jet printing. </DL> L may be interrupted by oxygen, sulphur, nitrogen, carbonyl (C=O) or a combination thereof. L may be optionally unsaturated and/or further substituted. When Z is a labile atom or group, it is preferably an atom or group which is displaceable by a hydroxyl group of cellulose under mildly alkaline aqueous conditions to form a covalent bond between the dye of Formula (1) and cellulose. Z may include halogen atoms, for example F or Cl; sulphonic acid groups; thiocyano groups; quaternary ammonium groups, for example trialkylammonium groups and optionally substituted pyridinium groups, for example 3- and 4-carboxy pyridinium groups. Also claimed are compositions and inks containing a compound of Formula (1), a process for ink jet printing using the inks and an ink jet printer cartridge containing the ink. |
