Abstract
The present invention provides one with a recording paper useful in ink jet recording processes. The recording paper is comprised of a substrate and a coating, with the coating comprising a pigment and a binder. The binder contains a water-soluble polymer, such as polyvinyl alcohol, and a curl behavior enhancing amount of a polyether, e.g., a polyalkylene glycol such as polyethylene glycol. Generally, the polyether has an average molecular weight of at least 400. The use of the present ink jet recording paper has been found to exhibit excellent imaging performance as well as superior curl behavior.
Claims21
A recording paper useful in ink jet recording comprised of a cellulose substrate and a coating, with the coating comprising a pigment and a binder, said binder being comprised of a water-soluble resin and a polyether, with the amount of polyether contained in the coating being at least 15 wt. % based on the total weight of the dry coating.
