    • A water absorbent cross-linked, carboxyalkylated cellulose-containing material is produced by impregnating a cellulose-containing material with an aqueous reaction solution including a carboxyalkylating agent, an alkali metal hydroxide, and a cross-linking agent dissolved in water in an initial content of 50 to 90% by weight, the molar ratio of the carboxylating agent to glucose groups of cellulose being 0.7 to 2.0; adjusting the water content of the aqueous reaction solution impregnated in the cellulose-containing material to 20 to 60% by weight and of at least 5% by weight below the initial water content by evaporating a portion of water; and subjecting the water content-adjusted cellulose-containing material to a simultaneous cross-linking and carboxylating reaction procedure at 50.degree. to 110.degree. C., while maintaining the water content at 20 to 60% and of at least 5% by weight below the initial water content.

    • 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.
