  • Publication number: 20180305863
    Abstract: A process for printing on a textile substrate comprising the steps of: (I) preparing an ink comprising the following components: (a) from 1 to 8 parts 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; (b) from 0 to 16 parts of a binder selected from one or more of an acrylic latex binder, a styrene acrylic latex binder and a styrene butadiene latex binder wherein the binder has a Tg in the range of from ?25° C. to 35° C.; (c) from 1 to 30 parts of one or more water-miscible organic solvents (d) from 0.1 to 3 parts of a surfactant; (e) from 0 to 5 parts of biocide; (f) from 0 to 10 parts of a viscosity modifier; (g) from 0 to 10 parts of a polyurethane latex binder with a Tg in the range of from ?25° C. to 35° C.
