Abstract:
1. A method for preparing an ink-jet recording sheet, comprising the steps of: (a) coating on, a substrate, an aqueous coating composition containing a hydrophilic binder and inorganic particles to form a porous layer having a surface; (b) drying the porous layer over a period, wherein the period comprises at least a constant drying rate period defined by a drying period over which the surface of the porous layer has a temperature that remains constant and a falling drying rate period defined by a drying period over which the surface of the porous layer has a temperature which rises; and (c) incorporating a solution containing an additive selected from the group consisting of a surface active agent, a hardener for the hydrophilic binder, an image stabilizer, a water-soluble polyvalent metal compound, a pH moderator and a cationic fixing agent, into the porous layer after the completion of the constant drying rate period in the same coating line used for coating the aqueous coating composition to form the porous layer.
