PROBLEM TO BE SOLVED: To provide an ink jet recording sheet which shows high surface gloss, excellent ink absorption and color development properties and further superb scratch-resistance. SOLUTION: This ink jet recording sheet has an ink receiving layer consisting of a pseudoboehmite-like alumina hydrate, formed on a support. This ink receiving layer has a protecting layer containing pearl necklace-like silica particles, formed on the layer. The particle diameter of the spherical primary particles of the pearl necklace-like silica is 5-100 nm, preferably 8-60 nm. The particle diameter of the pearl necklace-like silica particles is 30-800 nm, preferably 80-500 nm and in the case of the latter, especially satisfactory results are obtained. |
