Systems and methods for producing permanent ink-jet images are provided.
In one embodiment, a system includes a media substrate coated with a
porous media coating, wherein the porous media coating having inorganic
porous particulates, and wherein at least a portion of the inorganic
porous particulates have a first reactive group covalently attached
thereto. The system further includes an ink-jet ink containing a dye,
wherein the dye includes a second reactive group, and wherein the first
reactive group and the second reactive group are configured to react with
one another upon contact to form a covalent bond. In an alternative
embodiment, a method of producing permanent ink-jet images can includes
the steps of covalently bonding a first reactive group to an inorganic
porous particulate; coating the inorganic porous particulate onto a media
substrate to form a coated media substrate; ink-jetting a dye-containing
ink-jet ink composition onto the coated media substrate, wherein the dye
includes a second reactive group. The first reactive group and the second
reactive group, upon contact, can interact to form a covalent bond.
