ABSTRACT:
The present invention provides an ink-jet recording sheet which is excellent in water resistance, capable of providing excellent ink-drying property and image quality, substantially free from blurring, and suitable for use as OHP sheets of which a high transparency is necessitated. The present process for producing an ink-jet recording sheet comprises applying to a base sheet, an aqueous solution of a water-soluble resin having no radically polymerizable double bond in the molecule and selected from the group consisting of polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylamide, polyacryloyl morpholine, water-soluble polyvinyl acetal, poly-N-vinyl acetamide, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl methyl cellulose, gelatin, casein and derivatives of them, irradiating the resultant coating layer with electron beam before the coating layer is dried, to form a hydrogel, and drying the hydrogel. In the present invention, the water-soluble resin is usable in combination with a polyalkylene oxide compatible with the water-soluble resin.
