Abstract
Abstract A recording medium for recording with aqueous ink without direct contact of recording means therewith comprises an under layer and an upper layer provided thereon. The upper layer is formed of substantially water-resistant resin and is sufficiently thin to provide immediate water and air permeability and the under layer is more hydrophilic than the upper layer. There is also provided a recording process employing aqueous ink droplets and a recording medium as mentioned above.
