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 composition comprising a compound of Formula (1) or a salt thereof and compound of Formula (2) or a salt thereof: wherein:

Colorant composition, ink, printing process

A non-aqueous, substantially solvent-free and photoinitiator-free, particle beam curable ink having a viscosity less than 30 m Pa&#xb7;s at 60&#xb0; C., comprising:  Said inks are especially useful as ink jet printing inks. The inks are especially suitable for food contact applications and when printed and cured demonstrate good fat resistance and low levels of leaching to foodstuffs.
