Abstract:
A method of producing a print medium to reduce problems associated with the gradual dye-fade and color-shift of inks over time, and to provide improved resistance to physical handling is provided Specifically, a method can comprise steps of coating a media substrate with a porous coating composition of semi-metal oxide or metal oxide particulates to form a porous ink receiving layer, coating the porous ink-receiving layer with a latex layer configured to allow an ink-jet ink to be received at the porous ink-receiving layer, printing ink-jet ink on at least a portion of the latex layer to form ink-associated latex regions exclusive of non-printed latex regions, and heating the latex layer. The ink-jet ink can include an ink vehicle, a colorant, and a film promoting additive that lowers the film forming temperature of the latex particulates in the ink-associated latex regions. Upon heating, the ink-associated latex regions form a continuous film, and non-printed latex regions do not form a continuous film. Associated systems and ink-jet prints are also provided.
