Embodiment 1

[0196] -Manufacturing of support body-

[0197] The symmetrical weight is 186g / m 2 Coated paper (OK Kinto; Oji Paper Co., Ltd.) was corona-discharge-treated, and then coated with high-density polyethylene with a melt extruder to a thickness of 19 μm to form a resin layer on a matte surface (hereinafter , referring to the resin layer as the "back"). Further corona discharge treatment was applied to the resin layer on the back side, and then, as an antistatic agent, aluminum oxide (ALMINA SOL 100, manufactured by Nissan Chemical Industry Co., Ltd.) and silica (SNOTAXO, manufactured by Nissan Chemical Industry Co., Ltd.) were coated. ) system) dispersed in water according to the ratio (mass ratio) of 1:2, so that the dry mass is 0.2g / m 2 .

[0198] Furthermore, after performing corona discharge treatment on the felt surface (surface) side of the side where the resin layer is not provided, melt-extrude an anatase-type titanium dioxide containing 10%, a trace amount of ultramari...

Abstract

The present invention provides a paper-like medium for inkjet recording in which a colorant-receiving layer is strong without cracks, has excellent print density and glossiness of an image, and has no image bleeding over time. It is an inkjet recording paper having a colorant-receiving layer on the surface of a support, wherein the colorant-receiving layer is a coating formed by coating a coating liquid containing inorganic fine particles, a water-soluble resin, and a boron compound. The layer obtained by cross-linking and curing of the cloth layer. The above-mentioned cross-linking and curing is carried out by applying a solution containing a metal compound with a pH of 8 or higher to the above-mentioned coating layer or coating film at any of the following times: (1) coating the above-mentioned coating While distributing the liquid, (2) during the drying process of the coating layer formed by applying the above coating liquid, and before the coating layer shows decelerated drying, or (3) drying the coating layer formed by applying the above coating liquid After the coating layer dries and forms a coating film.

Description

technical field [0001] The present invention relates to a recording material suitable for inkjet recording using liquid inks such as water-based inks and oil-based inks, or solid inks that are solid at room temperature and melted and liquefied for printing. Specifically, it relates to an ink A paper-like medium for inkjet recording with excellent receptivity. Background technique [0002] In recent years, with the rapid development of the information industry, various information processing systems have been developed, and recording methods and devices suitable for the information systems have also been developed and put into practical use. [0003] Among the recording methods described above, the inkjet recording method is widely used in offices and homes from the viewpoints of recording on various recording materials, relatively inexpensive hardware (device), miniaturization, and excellent quietness. [0004] In addition, in recent years, with the increase in the resoluti...
