A process for preparing an encapsulated pigment dispersion suitable for use in an ink jet printing ink comprising the following steps in the order I) followed by II):

Process, dispersions and use

A polymeric dispersant obtained or obtainable by copolymerizing a monomer composition comprising at least the components: i) benzyl (meth)acrylate; ii) propylene glycol (meth)acrylate; wherein the weight ratio of component i) to component ii) is greater than 10:1.

Polymeric dispersants, dispersions, processes for preparing dispersions and the use of polymeric dispersants

Ink compositions containing ethylene glycol monobutyl ether

An ink-jet printing process comprising the steps (a) and (b) in any order or simultaneously: (a) applying an ink to a substrate by means of an ink-jet printer to form an image on a substrate; and (b) applying to the substrate a fixing composition comprising a liquid medium and a polymer containing a plurality of monoguanide and/or biguanide groups by means of an ink jet printer; characterised in that in the fixing composition has a chloride concentration less than 400 ppm by weight.

Compositions and processes

A composition comprising water-dissipatable polyurethane, water, colorant, a water-miscible organic solvent and a water-immiscible organic solvent. The compositions are useful as inks for ink jet printers.

Composition based on water-dissipatable polyurethane

An ink-jet printing process including the steps (a) and (b) in any order or simultaneously: The process avoids the need for expensive special papers previously used for ink jet printing.

Ink-jet printing process

A composition comprising a dye of Formula (I) and a dye of Formula (II) or salts thereof, and use of the composition in ink jet printing

Dye composition

1,3,4,-thiadiazolylazo dyes and ink compositions containing the same

Pyridonazo dyes and inks containing them

An ink composition comprising water, a water-dissipatable polyester, a disperse dye or a solvent soluble dye or a mixture of such dyes, a water-immiscible organic solvent and a water miscible organic solvent. The inks are useful in ink jet printers.

Aqueous ink compositions

A process for preparing an optical filter comprising a colored cross-linked polymeric coating on a transparent substrate, which comprises applying to the substrate, by a printing process, a mixture comprising one or more polymer precursor(s), and one or more dye(s) having one or more heterocyclic NH group(s) or one or more substituent (s) capable of forming a covalent bond with the polymeric precursor, and thereafter using the mixture. The invention also provides formulations comprising one or more polymer precursors and dyes, optical filters, and a novel dye.

Printing ink composition

Dyes of the Formula (1) and tautomers thereof:

1. An ink comprising water, a water-dissipatable polymer and a dye, wherein the dye carries a group of the Formula (1):

An ink comprising water, a water-dissipatable polymer and a dye of the Formula (1):
