PURPOSE:To obtain a transmissive light observing printed matter excellent in transparency and capable of obtaining a clear multicolor image, by a method wherein an image is recorded by ink jet recording on a recording material consisting of a transparent base and an ink-absorbing layer made to be transparent by heating, and the recording material is subjected to a heating treatment. CONSTITUTION:A coated layer of a thermoplastic resin obtained by adding a dispersant to a thermoplastic resin made to be transparent by heating is provided on the transparent base consisting of a film of a plastic such as a polyester or a diacetate, a glass plate or the like, and the dispersant is removed by eluation with a solvent, or other similar process is carried out to provide a porous ink-absorbing layer, thereby obtaining a recording material. Ink jet recording is conducted on the recording material, and after the ink is fixed, the material is subjected to a heat treatment at 70-200 deg.C for about 0.5-30min, thereby melting the thermoplastic resin and changing it into a uniform transparent structure. Accordingly, a transmissive light observing printed matter having a linear transmittance sufficient for use on an optical apparatus or the like is obtained. |
