Patent ID: 7427429

Claim:
A continuous, in-line process for making an ink-jet recording medium comprising the steps of: a) applying a radiation-curable coating to a surface of a substrate material; b) irradiating the radiation-curable coating to form a freshly irradiated coating that undergoes a curing process; and c) applying an ink-receptive coating over the freshly irradiated coating to form an ink-jet recording medium, wherein the ink-receptive layer contains at least one water soluble resin selected from the group consisting of: carboxyl-modified polyvinyl alcohols; sulfonic-modified polyvinyl alcohols; acrylamide-modified polyvinyl alcohols; cationic-modified polyvinyl alcohols; long chain alkyl-modified-polyvinyl alcohols; silicone-modified polyvinyl alcohols; maleic acid-modified polyvinyl alcohols; itaconic acid-modified polyvinyl alcohols; vinyl pyrrolidone copolymers; poly(ethylene glycol); poly(acrylic acids); starch; oxidized starch; cationic starch; hydroxypropyl starch; hydroxyethyl starch; cellulose; oxidized cellulose; cellulose ethers; cellulose esters; hydroxyethyl cellulose; carboxymethyl-cellulose; benzyl cellulose; phenyl cellulose; hydroxypropyl cellulose; ethyl hydroxyethyl cellulose; hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, hydroxy butylmethyl cellulose, dihydroxypropyl cellulose; hydroxypropyl hydroxyethyl cellulose; chlorodeoxycellulose; aminodeoxycellulose; diethylammonium chloride hydroxyethyl cellulose; hydroxypropyl trimethyl ammonium chloride hydroxyethyl cellulose; sodium cellulose sulfate; sodium carboxymethylhydroxyethyl cellulose; alginates; water-soluble gums; dextrans; carrageenan; xanthan; chitin; proteins; gelatins; agar; and mixtures thereof.
