Claim:
An ink jet recording sheet, comprising a substrate; a coating provided on the substrate, wherein the coating is formed by coating the substrate with a coating liquid containing a porous filler containing a first silica having an average diameter of 5 μm or less and a second silica having an average diameter of 10 μm or more, and a binder, the coating liquid having a pH of 4 or less, followed by drying the coating liquid; and a water-soluble cationic organic material impregnated into the coating, wherein the coating impregnated with the water-soluble cationic organic material forms an ink receiving layer, wherein the water-soluble cationic organic material is not present in the binder, wherein the water-soluble cationic organic material is impregnated in the ink receiving layer in an amount of 1.5 to 2.0% by weight, in terms of solid ratio of the ink receiving layer; and wherein the first filler and the second filler are contained in an amount of 40 to 80% by weight, in terms of solid ratio of the ink receiving layer.
