Systems and methods for producing permanent ink-jet images are provided.
In one embodiment, a system comprises a media substrate coated with a
porous media coating, wherein the porous media coating comprises
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 comprises 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 comprise 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.
