Abstract
A printed medium having a metallic luster includes an ink-receiving layer on a substrate and a layer of metal oxide particles disposed on the ink-receiving layer. A portion of the ink-receiving layer corresponding to at least one feature includes a non-particulate, light-absorbing colorant dispersed in the ink-receiving layer. An amount of the non-particulate, light-absorbing colorant in the ink-receiving layer portion is sufficient to render a predetermined hue to the metallic luster of the at least one feature. The metal oxide particles have an average diameter of about 3 nm to about 300 nm. The ink-receiving layer has pores that are smaller than the average diameter of the metal oxide particles.
Claims20
A printed medium comprising:
- a substrate having an ink-receiving layer, a portion of the ink-receiving layer corresponding to at least one feature having a metallic luster, the at least one feature comprising a non-particulate, light-absorbing colorant dispersed in the ink-receiving layer, an amount by weight of the non-particulate, light-absorbing colorant being about 0.001% to about 2% to render a predetermined hue to the metallic luster of the at least one feature;
- and
- a layer of metal oxide particles disposed on the ink-receiving layer at the at least one feature, the metal oxide particles having an average diameter of about 3 nm to about 300 nm, wherein the ink-receiving layer has pores that are smaller than the average diameter of the metal oxide particles.
A method for controlling a hue of an ink composition having a gold luster when applied to a print medium, the method comprising:
- providing a combination consisting essentially of an aqueous ink vehicle, iron oxide particles having an average diameter of about 3 nm to about 300 nm, and a non-particulate, light-absorbing colorant, wherein an amount of the non-particulate, light-absorbing colorant in the ink vehicle is about 0.001% to about 2% to render a predetermined hue to the gold luster of the ink composition, and
- applying the combination to a print medium to form at least one feature, wherein the print medium has an ink-receiving layer that has a pore size that is smaller than the average diameter of the iron oxide particles, the non-particulate, light-absorbing colorant being dispersed in the ink-receiving layer adjacent to the at least one feature.
