ABSTRACT:
The present invention provides an ink-jet recording sheet having a coloring agent accepting layer which contains a dispersion containing a cationic polymer with an average molecular weight of 60,000 or lower and having a sulfate ion concentration of 1.5% by mass or lower to the cationic polymer together with a water-soluble resin; an particle dispersion obtained by further granulating a pre-dispersion obtained by pre-dispersing a solution containing at least fine particles and a cationic polymer and the pre-dispersion and/or the particle dispersion is heated at room temperature for 5 hours or longer after pre-dispersion and/or after granulating; and a coating solution for coloring agent accepting layer obtained by adding a water-soluble resin to the particle dispersion.
