(A) Industrial Application Field The present invention relates to a recording medium recorded using ink, and in particular, a recording medium that has high density of images and characters recorded on the medium, and has excellent absorbency and storage stability of recorded images. This invention relates to an inkjet recording medium. (B) Prior art and its problems The inkjet recording method uses various operating principles to fly minute droplets of ink and make them adhere to a recording medium such as paper, thereby recording images, characters, etc. , high speed, low noise, easy multicolor printing, great flexibility in recording patterns, and no need for development or fixing, making it suitable for a variety of uses as a recording device for various shapes and color images, including kanji. It is rapidly becoming popular. Furthermore, images formed using the multicolor inkjet method can produce records that are comparable to multicolor printing using the plate making method or printing using the color photographic method, making it ideal for applications that require fewer copies to be produced. Since it is cheaper than photographic technology, it is being widely applied to the field of full-color image recording. Efforts have been made in terms of equipment and ink composition to use high-quality paper or coated paper used for ordinary printing and writing as the recording medium used in this inkjet recording method. However, as the performance of inkjet recording devices has improved and their applications have expanded, such as higher speeds, higher definitions, and full-color inkjet recording devices, more sophisticated characteristics have come to be required of recording media. In other words, the recording medium must have high ink dot density, bright and colorful tones, ink absorption is fast and the ink will not run out or smudge even when ink dots overlap, and the ink dots must be The horizontal diffusion of the image should not be larger than necessary, and the surrounding area should be smooth and not blurry. Furthermore, it is required that the resistance of the dye when the recorded image is exposed to ultraviolet rays, oxygen in the air, or water be not reduced, but preferably increased. Several proposals have been made to solve these problems. For example, JP-A-52-
No. 53012 describes inkjet recording paper, which is made by moistening a low-size base paper with a coating for surface treatment.
Further, JP-A-53-49113 discloses an inkjet recording paper in which a sheet containing urea-formalin resin powder is impregnated with a water-soluble polymer. Although these general paper type inkjet recording papers absorb ink quickly, they have the disadvantage that the periphery of dots tends to become blurred and the dot density is low. Further, JP-A No. 55-5830 discloses an inkjet recording paper having an ink-absorbing coating layer on the surface of the support, and JP-A No. 55-51583 discloses a non-colloidal pigment as a pigment in the coating layer. An example using silica powder is disclosed in JP-A-55-11829, and an example of smear paper using a two-layer structure with different ink absorption speeds is disclosed. These coated paper-type inkjet recording papers are improved over general paper-type inkjet recording papers in terms of dot diameter, dot shape, dot density, and color tone reproducibility, but there are Many inks are water-based inks that use water-soluble dyes, and if the image formed on the recording medium is exposed to water, the dye may dissolve again and ooze out, significantly reducing the value of the recorded material. There is a problem. Therefore, in order to improve this drawback, for example, JP-A-55-53591 discloses an example in which a water-soluble metal salt is applied to the recording surface, and JP-A-56-84992 discloses a method in which a polycationic polymer electrolyte is applied. An example of a recording medium containing on the surface is disclosed in JP-A-55-150396, and a method of applying a water-resistant agent that forms a lake with the dye in the ink after inkjet recording, and JP-A-55-150396 describes No. 56-58869 discloses a method for making a recording sheet coated with a water-soluble polymer waterproof by insolubilizing the water-soluble polymer after inkjet recording. However, with these methods, the effect of water resistance may be weak, or the water resistance agent may cause some kind of reaction with the dye, reducing the shelf life of the dye, making it difficult to achieve both sufficient water resistance and light resistance. It was quite difficult. (C) Purpose of the Invention The present inventors have intensively studied methods for improving the water resistance and light resistance of inkjet recording paper on which characters and images are recorded with water-based ink using water-soluble dyes, and have developed methods for improving the water resistance and light resistance of the images. Achieved the purpose.
That is, an object of the present invention is to provide a recording paper suitable for inkjet recording that improves water resistance without reducing the light resistance of images recorded using water-soluble dyes. (D) Structure and operation of the invention In other words, the present invention provides an inkjet recording paper that obtains a recorded image by using a water-based ink containing a water-soluble dye on a recording paper made mainly of pulp fibers. This is an inkjet recording paper characterized by containing a soluble magnesium compound. The cationic resin referred to in the present invention refers to a monomer, oligomer, or polymer that dissociates and exhibits cationic properties when dissolved in water, preferably having a quaternary ammonium group, and particularly preferably one of the following () to ().

Among these many water-soluble organic solvents, polyhydric alcohols such as diethylene glycol and lower alkyl ethers of polyhydric alcohols such as triethylene glycol monomethyl ether and triethylene glycol monoethyl ether are preferred. Examples of other additives include PH regulators, sequestrants, antifungal agents, viscosity regulators, surface tension regulators, wetting agents, surfactants, and rust preventives. Ink jet suitability was measured by the following method. Light resistance was measured using a xenon fade meter (Suga Test Instruments Co., Ltd.) for the image area obtained by solid printing with C, M, Y, and Bk inks using a Canon inkjet printer (A-1210). Manufactured by FML−
25X-HCL type) at 40℃, 60%, illuminance 41w/ m2
The color density before and after irradiation was measured using a Macbeth densitometer RD514, and the percentage of the color density after irradiation divided by the color density before irradiation was expressed as light resistance (residual rate). Water resistance was determined by using the same Canon inkjet printer to print solid images using C, M, Y, and Bk inks, immersing them in running water at 30°C for 3 minutes, and measuring the density before and after immersion using Macbeth density. The water resistance value was determined by dividing the concentration after immersion by the concentration before immersion. The higher the value, the better the water resistance. The ink absorption speed is measured immediately after solid red printing (magenta + yellow) (about 1 second) using a Sharp or Canon inkjet printer.
The paper was fed to the paper, and the paper was brought into contact with a paper presser roll or a finger, and judgment was made based on whether dirt appeared or not.
