Provided by the present invention is an ink jet receiver sheet comprised of a substrate and a coating containing a modified polyvinyl alcohol. The substrate is preferably paper based, and the modified polyvinyl alcohol is preferably carboxylated, acetoacetylated or modified with sulfonic acid. The use of modified polyvinyl alcohols in accordance with the present invention work very well with the class of ink jet inks that contain a cosolvent comprised of a polyol of at least three hydroxy groups or an amido functional cosolvent such as pyrrolidone. With the modified polyvinyl alcohol, the ink is found to spread upon contact with the surface and provide good print quality and good dry times.
