Abstract:
An ink jet recording material formed by a process which comprises the following steps:coating a base material with a first ink-receptive layer comprising a high valence metallic halide which is capable of reacting with an alginate; and coating the surface of said first ink-receptive layer with a second ink-receptive layer comprising an alginate so as to generate a gel layer at the interface between said first ink-receptive layer and said second ink-receptive layer; wherein said first ink-receptive layer comprises: (a) polyvinylpyrrolidone of 0.5 to 5 percent by weight, said polyvinylpyrrolidone having a molecular weight of about 8*103 to 2.9*106; (b) polyvinyl alcohol of 1 to 15 percent by weight, said polyvinylpyrrolidone having a molecular weight of about 1*104 to 1*105; and (c) hydroxyethyl cellulose of 1 to 10 percent by weight.
