An aqueous ink including: from 0.1 to 8 parts by weight of 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; from 10 to 25 parts by weight of a first solvent selected from one or more of the group consisting of ethylene glycol, propylene glycol, dipropylene glycol and triethylene glycol; from 2 to 10 parts by weight of a second solvent selected from one or more of the group consisting of 2-pyrrolidone, N-methyl-2-pyrrolidone, N-ethyl-2-pyrrolidone, N-cyclohexyl-2-pyrrolidone and N,N-dimethylacetamide; from 20 to 45 parts by weight of glycerol; from 4 to 12 parts by weight of a styrene butadiene latex binder and/or a polyurethane latex binder; from 0.1 to 2 parts by weight of an acetylenic surfactant; from 0 to 2 parts by weight of 1,2-benzisothiazolin-3-one; and the balance to 100 parts by weight water. Also ink-jet printing processes, printed materials, ink containers and ink-sets.

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.
