Abstract: A recording medium (or sheet) is prepared by forming a porous layer, for forming an image, on at least one side of a support, in which the porous layer comprises an alicyclic epoxy compound. The alicyclic epoxy compound may have a plurality of epoxy groups, and for example, may include an epoxycycloalkylalkyl-epoxycycloalkane carboxylate. The mean pore size of the porous layer is about 0.1 to 20 &mgr;m, and the porosity thereof is about 20 to 85%. A resin constituting the porous layer may comprise a cellulose-series resin or the like, and may have a microphase-separated structure. In the porous layer, the amount of the alicyclic epoxy compound is about 1 to 200 parts by weight relative to 100 parts by weight of the resin constituting the porous layer. The recording sheet ensures forming of a clear image, and improved scratch resistance.
