An ink comprising: (a) from 0.5 to 5 parts of a self-dispersible pigment; (b) from 1 to 10 parts of a styrene acrylic latex binder and/or styrene butadiene latex; (c) from 0 to 5 parts of a glycol selected from the group consisting of ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol or triethylene glycol; (d) from 1 to 10 parts of 2-pyrrolidone; (e) from 1 to 15 parts of glycerol; (f) from 0.1 to 3 parts of an acetylenic surfactant; (g) from 0.001 to 5 parts of biocide; (h) from 0 to 10 parts of a viscosity modifier; and (i) the balance to 100 parts water. Also an ink-jet printing process, a printed substrate, an ink-jet printer ink container and an ink-jet printer with a re-circulating printer head.

Inks

A method for printing on a water-soluble material which comprises the following steps:

Method for printing on water-soluble material

A process for printing on a water-soluble material using a self-dispersible pigment which comprises a carboxy-functional dispersant crosslinked around a pigment core by a crosslinking agent having at least two groups selected from oxetane, carbodiimide, hydrazide, oxazoline, aziridine, isocyanate, N-methylol, keteneimine, isocyanurate and epoxy groups. Also inks, ink-sets, printed material and ink-jet printers.

Printing process

An ink composition comprising: a) 0.2 to 20 parts of one or more glycols selected from the group consisting of ethylene glycol, diethylene glycol, propylene glycol or dipropylene glycol; b) 30 to 50 parts of glycerol; c) 0.5 to 10 parts of 2-pyrrolidone; d) 0.5 to 9 parts of colorant; e) 30 to 70 parts of water; f) 0 to 3 parts of surfactant; g) 0 to 5 parts biocide; wherein all parts are by weight. Also ink-sets, printing processes and printed material.

Inks for ink-jet printing

An ink comprising an encapsulated particulate solid and a liquid vehicle wherein: I) the encapsulated particulate solid comprises a particulate solid encapsulated with a cross-linked dispersant shell; and II) the ink comprises the components: a. from 0.1 to 20 parts of the encapsulated particulate solid; b. from 20 to 40 parts of glycerol; c. from 1 to 30 parts of ethylene glycol; d. from 0 to 20 parts of 2-pyrrolidone; e. from 0.01 to 3 parts of surfactant; f. from 0 to 10 parts of water-soluble polymer; g. from 0 to 20 parts of polymer particles; h. from 0 to 2 parts of biocide; i. from 20 to 75 parts of water; wherein all the parts are by weight and the sum of the components a. to i. is 100 parts.

Ink and printing process

A process for printing a substrate comprising applying thereto an ink by means of an ink jet printer, wherein the ink comprises a latex binder, a liquid medium comprising water and organic solvent, and polymer-encapsulated pigment particles comprising a carboxy-functional dispersant crosslinked around a pigment core by a crosslinking agent, wherein the ink has a minimum film-forming temperature below 70&#xb0; C. Inks are also claimed. The process and inks are useful for printing temperature-sensitive substrates, e.g. foil balloons and wrapping materials for special occasions.

Inks and printing process

A process is provided for printing an image on a substrate, the process comprising applying to the substrate an ink composition which comprises a liquid medium and a compound of Formula (1): wherein:

Black azo dyes and their use in ink jet printing

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 compound of Formula (1) and salts thereof: wherein: Also compositions comprising these compounds, ink-jet inks, an ink jet process and an ink-jet cartridge.

Magenta dyes and their use in ink-jet printing

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 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.
