Abstract (en)

Ink jet ink receptive recording media are provided that contain a substrate having an ink receptive coating thereon. The coatings used to prepare the media contain a cellulose ether and an aluminum oxide particulate. Preferably, the coating compositions contain about 50% to about 95% of the cellulose ether on a weight/weight basis, based on the amount of solids in the coating composition, and preferably the cellulose ether has a hydroxyalkyl content of 0% to about 32% and a methoxy content of about 16% to about 32%. The aluminum oxide particulate utilized preferably possesses an average dispersed particle size of about 10 nanometers to about 200 nanometers, (more preferably of about 30 nanometers to about 170 nanometers), a pH that falls within the acidic to neutral pH range (more preferably from about pH 3 (acidic) up to about pH 7 (neutral)). The provided ink jet ink receptive recording media possess the combined properties of (i) a low level of ink cracking, (ii) good optical density, and (iii) a good dry time, when printed in an ink jet printing process.
