Abstract:
1. A method of producing ink-jet printed images on plastic surfaces, comprising the steps of: a. providing a plastic object; b. coating at least part of the surface of the plastic object with a mixture containing a chemically cross-linkable system; c. evaporating off the volatile part of the mixture, thus depositing a solid hydrophilic layer on the surface of the plastic object without causing the coating to cross-link; d. providing an ink-jet ink comprising a non-reactive colorant and aqueous carrier; e. jetting the ink by means of an ink-jet system onto the surface of the coating on the plastic object so that it is absorbed into the coating; f. providing energy in sufficient quantity to the printed surface to cross-link the entire surface coating including the absorbed ink-jet inks to form a non-smearable print.
