    Abstract: A mat type recording medium for ink jet printing is provided which exhibits optimum printability no matter which of dye ink and pigment ink may be used in printing. The recording medium, which is for recording with use of water-based ink containing an ink colorant, comprises a paper base and an ink receptive layer formed on a surface of the paper base, the ink receptive layer comprising a porous layer containing an inorganic pigment and also containing a substance reactive with the ink colorant. The recording medium is characterized in that a droplet of 4 µl distilled water dropped onto a surface of the ink receptive layer is absorbed in a first absorbing stage of absorbing the droplet at a first absorbing speed V1 (µl/sec) within one second after the dropping, a second absorbing stage of absorbing the droplet at a second absorbing speed V2 (µl/sec) after the first absorbing stage, and a third absorbing stage of absorbing the droplet at a third absorbing speed V3 (µl/sec) after the second absorbing stage, the droplet absorption in the first to third absorbing stages satisfying the relationships of 0

    Abstract: A recording medium includes a substrate and two or more ink receiving layers on each of a first surface and a second surface of the substrate. The ink receiving layers each contain a pigment and a binder. A 1 , A 2 , B 1 , and B 2 (nm) satisfy the relationships (1), (2), and (3), where A 1 is the peak of the pore radius distribution of the outermost ink receiving layer (2) on the first surface side, A 2 is the peak of the pore radius distribution of the ink receiving layer (3), B 1 is the peak of the pore radius distribution of the outermost ink receiving layer (4) on the second surface side, and B 2 is the peak of the pore radius distribution of the ink receiving layer (5). The arithmetic average roughness Ra specified in JIS B 0601 of each of the outermost ink receiving layers (2, 4) is 0.50 µm or more.

    Abstract: The invention provides a recording medium capable of inhibiting occurrence of undertrapping, lowering the visibility of scratches on the outermost surface of the recording medium and inhibiting occurrence of a mottled pattern when recording is conducted. The recording medium has a substrate and an ink receiving layer provided on the substrate, wherein the arithmetic average roughness Ra of the outermost surface of the recording medium as prescribed by JIS B 0601:2001 is 1.1 µm or more and 2.5 µm or less, and the skewness Rsk of a roughness curve of the outermost surface of the recording medium as prescribed by JIS B 0601:2001 is 0.1 or less.

    Abstract: Image-recorded article having coating layer on part of image formed is formed by providing liquid composition having polymer, providing image-recorded article formed on recording medium using ink-jet recording method, and applying the liquid composition to part of an image of the recorded article. Formation of image-recorded article having coating layer on part of the image formed, comprises providing liquid composition having polymer, providing image-recorded article formed on recording medium using ink-jet recording method, and applying the liquid composition to part of an image of the recorded article to insolubilize the polymer on the surface of the image to form the coating layer at a position where liquid composition is applied. The recording medium has a surface that insolubilizes the polymer. Independent claims are also included for: (a) a liquid composition for forming coating layer on part of image-recorded article comprising aqueous medium, and polymer having the structure of formula -COOA; and (b) an ink-jet recording apparatus (61) comprising liquid holding part for holding liquid, and liquid ejecting part for ejecting the liquid fed from the liquid holding part. A : alkali metal, ammonium, or organic ammonium.
