PURPOSE:To obtain a high-performance recording sheet capable of speedily absorbing an ink and free from blotting of inks or mixing of a black ink, by constituting an ink-receiving surface of a porous resin, in a recording sheet used for ink jet recording or the like. CONSTITUTION:A porous resin layer 1 is produced, for example, by a method wherein a resin is kneaded with a substance capable of foaming under heat or light, is molded, and the molded article is heated or is irradiated with light, or by a method wherein a resin with particulates of a water-soluble inorganic salt dispersed therein is molded, and the molded article is immersed in water to dissolve the inorganic salt. The porous resin layer is used as an ink-receiving layer for a recording sheet, which may consists solely of the porous resin layer 1, may comprise the resin layer 1 and another resin layer 2 consisting of the same resin material as that used for the layer 1, or may comprise the porous resin layer 1 adhered onto a base 3 such as a paper. The recording sheets are selected in accordance with the purpose of recording or use. |
