More Information
Summary: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.
