A process for printing an image on a substrate including applying thereto a composition including a liquid medium and a compound of Formula (1) A-N&#x2550;N-L-N&#x2550;N-A wherein: each A independently is optionally substituted aryl or heteroaryl; and L is an optionally substituted, optionally metallised 1,8-dihydroxynaphthylene group; provided that: (i) at most one of the groups represented by A has a hydroxy substituent ortho to the &#x2014;N&#x2550;N&#x2014; groups shown in Formula (1); and (ii) Formula (1) is not: Also claimed are compositions for printing, compounds and processes for making the compounds.

Compositions and inks containing disazo dyes

A metal chelate of Formula (1) or salt thereof. Formula (1) wherein: Rand Rare each independently H or an organic group; M is a metal; p is 1 to 4; Y is an optionally substituted heterocyclic ring with a nitrogen ortho to the azo bridge; G is a substituent; and n is 0 to 5. Also inkjet inks, cartridges and processes 

Magenta metal chelate dyes and their use in ink-jet printers

A process for printing an image on a substrate comprising applying thereto a composition comprising a liquid medium and a compound of Formula (1):T-Q-N&#x2550;N-L-T&#x2003;&#x2003;Formula (1)wherein:

Printing process using specified AZO compounds

A process for coloration of a substrate comprising applying thereto means of an ink jet printer a composition comprising a medium and a compound of Formula (1):wherein:

Azo dyes containing a barbituric acid moiety, ink-jet printing inks and processes

A water-dissipatable polymer having colorant attached thereto through a covalent &mdash;O-link and an ink comprising the water-dissipatable polymer and a liquid medium.

Ink-jet ink compositions

The invention relates to polyurethanes, inks comprising polyurethanes and their use in ink jet printing where the polyurethane comprises a colored water-dissipatable polyurethane obtainable from the reaction of a polyisocyanate, a compound providing water-dispersing groups and a colorant having at least two functional groups.

Colored polyurethanes

The invention relates to polyurethanes, inks comprising polyurethanes and their use in ink jet printing where the polyurethane comprises a colored water-dissipatable polyurethane obtainable by chain-terminating a polyurethane prepolymer with a colorant.

Multicolor ink jet printing method

Phthalocyanine compounds substituted by from 1 to 8 substituents of formula (&mdash;O&mdash;R&mdash;O&mdash;) wherein R is a 1,2-arylene group are provided. Preferably, the phthalocyanine compounds are substituted by catechol. Additional substituents which may be present include hydrocarlyloxy, hydrocarbylthio, halogen and sulphonic acid or a salt thereof.

Phthalocyanines

A process for producing an image on a substrate comprising printing an ink onto the substrate, characterized in that the ink contains a reactive dye, the substrate is an acid paper and the printing is performed by an ink jet printer. Also claimed is an acid paper printed by means of the process.
