  • Patent number: 7297365
    Abstract: A method of manufacturing a recorded matter having an ink-receiving layer of a porous structure. The ink-receiving layer has an image region where an image is formed with a coloring material. The method includes the steps of (i) applying an ink to the ink-receiving layer to obtain an image region where an image is formed with a coloring material contained in the ink, (ii) applying a liquid comprising a non-volatile liquid not dissolving the coloring material to the ink-receiving layer, and (iii) forming a portion in which all or substantially all of the coloring material distributed in a thickness direction of the ink-receiving layer is embedded in the non-volatile liquid by rubbing the non-volatile liquid after it is applied. The non-volatile liquid contains an ester of a saturated fatty acid and an alcohol.
