Abstract
An ink jet recording material capable of recording clear ink images having a high color density at a high speed without blotting the ink image and provided with a high surface strength has an ink receiving layer formed on a support, which may be a plastic film or a synthetic paper sheet, including synthetic amorphous silica particles and a binder, the surface of the ink receiving layer being characterized by exhibiting a peak area ratio (C.sub.1 s/Si.sub.2 p) of carbon electron 1s to silicon electron 2p of 6.0 to 35.0, determined by an X-ray photo-electron spectroscopy.
