A system and process for direct printing onto textiles utilizes an aqueous ink having a non-aqueous dispersed liquid phase; a continuous aqueous phase; a thermal initiator; and a colorant. The continuous aqueous phase is comprised of water, a water miscible organic solvent, and a surfactant. The non-aqueous liquid phase, dispersed in the continuous aqueous phase, includes a prepolymer liquid wherein the state of the prepolymer liquid irreversibly changes from a liquid to a solid in response to irradiation of electron beams and/or application of heat.

The disclosure provides a structural colored ink and its preparation and use. The ink comprises 10 to 15 wt. % of a pigment, 20 to 40 wt. % of a resin, 50 to 65 wt. % of a solvent, and 2 to 5 wt. % of an auxiliary. The pigment comprises an optically variable pigment and a pearlescent pigment. The resin is at least one selected from a polyurethane resin, an acrylic resin, and a nitrocellulose solution. The solvent is an alcohol, an ester, or a mixed solvent thereof. The ink is alcohol-soluble and environmentally friendly, and has excellent anti-sediment property and stability. Prints made from the ink can have a high color purity, a mild color changing effect, and a color changing and sparkling effect when the viewing angle is changed. So, the ink can have a potential application prospect in screen printing for medium- and high-end packaging products.
