  • Patent number: 8314175
    Abstract: The present invention provides an aqueous composition for recording medium in a form of aqueous dispersion solution comprising a polyvinyl alcohol-based resin (A) having an average saponification degree of 80-89 mol % and an average polymerization degree of 1700-3500, and containing a polyvinyl alcohol having 1,2-diol structural unit on a side chain thereof, represented by a general formula (1); an inorganic microparticle (B); and a boron compound (C). The aqueous composition of the present invention is not likely to become gel and therefore exhibit excellent preservation stability. Furthermore, the aqueous composition provides a recording layer serving as an ink receiving layer/glossy layer satisfied with gloss, ink absorbency, and water resistance. Accordingly, the present invention may also provide an ink-jet recording medium satisfying surface gloss by forming a coating layer of the inventive aqueous composition on a substrate, even when the substrate has water resistance.
