Abstract
Smear resistant ink jet ink images and methods for making such are disclosed and described. Generally, a smear resistant ink jet ink image includes an ink jet ink image upon a print substrate, and a water insoluble protective film having contact with the ink jet ink in the image. In one aspect, the film may include a combination of water soluble film forming polymers that become water insoluble upon interaction with one another. In another aspect, the water soluble film forming polymers may be interacted at the print substrate to form the water insoluble film.
