Embodiment 1

[0081] A coated paper sheet as a substrate was prepared as follows. Prepared by mixing 100 parts by weight of granular barium sulfate with an average particle size of 0.6 μm obtained by reacting barium sulfate and barium chloride, 10 parts by weight of gelatin, 3 parts by weight of polyethylene glycol, and 0.4 parts by weight of chromium alum Coating liquid. Apply the coating liquid to a basis weight of 130 g / m 2 On a substrate sheet with a Bekk smoothness of 340 seconds, a dry thickness of 20 μm was obtained. The coated sheet was supercalendered to give a substrate with a surface smoothness of 400 seconds.

[0082] By mixing 100 parts by weight of vinyl chloride-vinyl acetate-acrylic acid copolymer (minimum film-forming temperature: 130° C., average particle size: 0.75 μm), and 10 parts by weight of styrene-acrylate copolymer (Movinyl 752, trade name, Hoechst Gosei K.K.; minimum film forming temperature: 30° C., average particle diameter: 0.1 μm) was mixed, and then the so...

Embodiment 2

[0103] The recording medium of the present invention was prepared in the same manner as in Example 1, except that acrylic acid-modified colloidal silica (Movinyl 8030, trade name, Hoechst Gosei K.K.; minimum film-forming temperature: 30° C., average particle size: 0.06 μm) was used instead Styrene-acrylate copolymer.

[0104] The porous layer thus obtained was observed by SEM, and it was confirmed to have partial fusion of the water-dispersible resin particles.

[0105] For this recording medium, printed matter was prepared and evaluated in the same manner as in Example 1. Table 1 presents the results.

Embodiment 3

[0107] A recording medium of the present invention was prepared in the same manner as in Example 1, except that a vinyl acetate-acrylic acid copolymer (Movinyl 630, trade name, Hoechst Gosei K.K.; minimum film-forming temperature: 19° C., average particle size: 0.15 μm) was used instead Styrene-acrylate copolymer.

[0108] The porous layer thus obtained was observed by SEM, and it was confirmed to have partial fusion of the water-dispersible resin particles.

[0109] For this recording medium, printed matter was prepared and evaluated in the same manner as in Example 1. Table 1 presents the results.

Abstract

An ink-jet recording medium having, on a base material, a porous resin layer containing water-dispersible resin particles B having a minimum film-forming temperature of not lower than 0 DEG C, and water-dispersible resin particles A having a minimum film-forming temperature higher than the film-forming temperature of the water-dispersible resin particles B and having an average particle size larger than the average particle size of the water-dispersible resin particles B.

Description

technical field [0001] The present invention relates to a recording medium suitable for inkjet recording. Background technique [0002] The inkjet recording system is performed by ejecting ink droplets using various ink ejection methods or the like, in which electrostatic suction is used, mechanical vibration of the ink is generated by a piezoelectric element, or alternately, ink bubbling is generated by heating, so that the entire or part of the The jetted ink is deposited onto a recording medium such as a paper sheet, and a plastic film having an ink-receiving layer thereon. Ink-jet recording systems are attracting attention due to lower noise generation, high printing speed, and suitability for multi-color printing. Inkjet recording systems are being developed to be widely used as printers, copiers, word processors, facsimile machines, plotters, and other information machines. [0003] In recent years, high-performance digital cameras, digital televisions, and scanners ...
