(A) Industrial application field This explanation relates to recording paper that records using ink, and in particular, the density of images and characters recorded on the recording paper is high, and it has excellent absorbency and storage stability of recorded images. This paper relates to inkjet recording paper. (B) Prior art and its problems In the inkjet recording method, micro droplets of ink are ejected using various operating principles and attached to recording paper such as paper to record 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 spreading in the world. 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 paper 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 definition, and full-color inkjet recording devices, recording paper has come to be required to have even more sophisticated properties. In other words, the recording paper should have a high inkjet density, a bright and colorful color tone, the ink should be absorbed quickly and the ink should not run out or smudge even when ink dots overlap, and the ink dots should 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 an inkjet recording paper made by moistening a low-size base paper with a dye 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 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 paper gets wet with water, the dye will 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 paper containing a water-resistant material on the surface is also disclosed in Japanese Patent Application Laid-open No. 150396/1983, which describes a method of applying a waterproofing agent that forms a lake with the dye in the ink after inkjet recording. 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. Therefore, in order to improve the light resistance, for example, JP-A-54-68303, JP-A-54-85804 and JP-A-56-
No. 18151 discloses an example in which an ultraviolet absorber is added to an ink liquid. However, these ultraviolet absorbers have problems in that they reduce the jetting stability of the ink and have low solubility, so they cannot be added in large amounts and are less effective when added in small amounts. Another solution is to incorporate ultraviolet absorbers such as benzophenone and benzotriazole into the inkjet recording sheet.
No. 74192, No. 57-74193, and No. 57-87988, but these have poor solubility in water and are difficult to use in large amounts, or are ineffective in small amounts. When used in emulsified form, there are problems such as the influence of the emulsifier. (C) Object of the Invention The present invention is directed to improving the suitability for inkjet as described above and providing excellent water fastness and light fastness of water-based ink images, especially the light fastness and discoloration fastness of water-soluble black dyes or water-soluble magenta dyes. The purpose is to provide recording paper with improved performance. (D) Structure and operation of the invention That is, the present invention provides an inkjet recording paper for forming a recorded image using a water-based ink containing a water-soluble dye, wherein the recording paper has the following functional groups (). This is an inkjet recording paper containing a hydrazide compound. Here, R 1 and R 2 are hydrogen or a carbon number of 1 to 22
represents an alkyl group, a hydroxyalkyl group, a phenyl group, etc. Furthermore, R 1 and R 2 may be condensed to form a ring. In addition, the carbonyl side has 1 carbon number
-22 organic acids, polymers such as polyacrylic acid, and carbamic acids. The hydrazide compound referred to in the present invention is an ester of the corresponding carboxylic acid, an acid derivative such as an acid halide, or an ester or isocyanate, and a compound of the general formula

ンクジエツト適性を測定した結果を表１に示す。[Formula] etc. In the present invention, the recording paper containing the hydrazide compound is prepared by dissolving or dispersing the hydrazide compound using a size press device installed in the middle of disintegrating pulp fibers to form a slurry in a paper machine. A method of impregnating a coating solution by dipping or coating it, and further applying a coating solution containing a hydrazide compound to a suitable support using a conventional coating device to form an ink-receiving layer containing a hydrazide compound. There are methods such as providing a hydrazide-based compound dissolved or dispersed on an ink-receiving layer made of an ink-absorbing pigment, an adhesive, and the like. In this case, it is also possible to use commonly used fillers, pigments, adhesives and other additives. In addition, if it is necessary to impart water resistance to the image, it is possible to use a cationic resin in combination, and in the present invention, it is rather actively used in order to simultaneously improve water resistance and light resistance. It is desirable to do so. Examples of fillers or pigments that can be used in the present invention include light calcium carbonate, heavy calcium carbonate, kaolin, talc, calcium sulfate, barium sulfate, titanium oxide, zinc oxide, zinc sulfide, zinc carbonate, satin white, aluminum silicate, White pigments such as diatomaceous earth, calcium silicate, magnesium silicate, synthetic amorphous silica, aluminum hydroxide, alumina, lithopone, etc. and organic pigments include styrene plastic pigments, acrylic plastic pigments, microcapsules, urea resin pigments, etc. There is. Among these, synthetic amorphous silica and aluminum hydroxide are preferably used in the present invention. 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 the following () to (). A compound having a structure represented by the general formula. In the formula, R 1 , R 2 , R 3 are alkyl groups, m is 1 to 7,
n represents 2 to 20, and Y represents an acid group. In the formulas () to (), R 1 and R 2 are −CH 3 and −CH 2
-CH3 , -CH2 - CH2 -OH and Y represent acid groups. () Polyalkylene polyamine dicyandiamide ammonium salt condensate Examples of the compound represented by the general formula () include Nalpoly 607 (manufactured by Nalco Chemical Co., Ltd.) and Polyfix 601 (manufactured by Showa Kobunshi Co., Ltd.). The compounds represented by general formulas () to () are polydiallylamine derivatives, obtained by cyclopolymerization of diallylamine compounds, and Percoll 1697

Corp), PAS (Nitto Boseki Co., Ltd.), Neo Fixtures
Examples include RPD (manufactured by NICCA Chemical Co., Ltd.). Furthermore, examples of the compound represented by the general formula () include Neofix RP-70 (manufactured by NICCA Chemical Co., Ltd.). The content of the cationic resin represented by these general formulas () to () is usually 0.1 to 4 g/m 2 , preferably 0.2 to 2 g/m 2 . Examples of adhesives that can be used in the present invention include:
Oxidized starch, etherified starch, cellulose derivatives such as carboxymethyl cellulose and hydroxyethyl cellulose, casein, gelatin, soy protein, polyvinyl alcohol and its derivatives, maleic anhydride resin, ordinary styrene-butadiene copolymer, methyl methacrylate-butadiene copolymer Conjugated diene polymer latex such as polymer, acrylic polymer latex such as polymer or copolymer of acrylic acid ester and methacrylic acid ester,
Heat curing of vinyl polymer latices such as ethylene-vinyl acetate copolymers, functional group-modified polymer latices with monomers containing functional groups such as carboxyl groups, melamine resins, urea resins, etc. of these various polymers. Water-based adhesives such as synthetic resins, and synthetic resin adhesives such as polymethyl methacrylate, polyurethane resins, unsaturated polyester resins, vinyl chloride-vinyl acetate copolymers, polyvinyl butyral, and alkyd resins are used alone or in combination. . These adhesives are used in an amount of 2 parts to 120 parts, preferably 5 parts to 50 parts, per 100 parts of the pigment, but the ratio is not particularly limited as long as the amount is sufficient to bind the pigment. However, if 120 parts or more of adhesive is used, the adhesive film formation reduces the void structure or makes the voids extremely small, which is not preferable. Other additives include pigment dispersants, thickeners,
Fluidity modifier, antifoaming agent, foam suppressor, mold release agent, foaming agent, penetrating agent, colored dye, colored pigment, optical brightener,
UV absorbers, antioxidants, preservatives, anti-bacterial agents,
A waterproofing agent and the like may also be added as appropriate. As the support, a sheet material such as paper or thermoplastic resin film is used. In the case of paper, it is paper with no sizing agent added or with appropriate sizing, and may or may not contain filler. In the case of thermoplastic films, transparent films such as polyester, polystyrene, polyvinyl chloride, polymethyl methacrylate, cellulose acetate, polyethylene, polycarbonate, etc., and white opaque films filled with white pigment or formed by fine foaming are used. Examples of white pigments to be filled include titanium oxide, calcium sulfate,
Calcium carbonate, silica, clay, talc, zinc oxide, and many others are used. It is also possible to use so-called laminated paper, which is produced by laminating these resin films on the surface of paper and processing it with molten resin. A subbing layer or corona discharge processing may be applied to improve the adhesion between the resin surface and the ink receiving layer. A sheet simply coated on a support can be used as it is as a recording sheet according to the present invention, but it is also possible to impart surface smoothness by passing it between roll nips under heat or pressure using, for example, a super calender or gloss calender. be. In this case, the degree of processing may be limited because excessive processing by supercalendering will reduce the ink absorbency due to the carefully formed voids between particles. The aqueous ink referred to in the present invention is a recording liquid comprising the following colorant, liquid medium, and other additives. As the coloring agent, water-soluble dyes such as direct dyes, acid dyes, basic dyes, reactive dyes, and food colorings are preferably used.

Alkyl alcohols having 1 to 4 carbon atoms such as sec-butyl alcohol, tret-butyl alcohol, and isobutyl alcohol; amides such as dimethylformamide and dimethylacetamide; ketones or ketone alcohols such as acetone and diacetone alcohol; tetrahydrofuran and dioxane Ethers such as polyethylene glycol, polypropylene glycol, etc.; polyalkylene glycols such as ethylene glycol, propylene glycol, butylene glycol, triethylene glycol, 1,2,6-hexanetriol, thiodiglycol, hexylene glycol, diethylene glycol, etc. Alkylene glycols having 2 to 6 alkylene groups; examples include lower alkyl ethers of polyhydric alcohols such as glycerin, ethylene glycol methyl ether, diethylene glycol methyl (or ethyl) ether, and triethylene glycol monomethyl ether. 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 monomethyl ether are preferred. Examples of other additives include PH regulators, sequestrants, antifungal agents, viscosity regulators, surface tension regulators, wetting agents, surfactants, and rust preventives. According to the present invention, when recording is performed using a water-based ink containing a water-soluble dye on a recording paper containing a hydrazide compound, the light resistance of the image is improved. The reason for this is not clear, but it is thought that fading or discoloration of dyes is caused by radicals generated on dye molecules by ultraviolet rays, etc., and hydrazide compounds trap and stabilize these generated radicals. , it is thought that the decomposition of the dye may be suppressed. 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 FAL-
25X-HCL type) at 40℃. 40 at 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). Further, discoloration and fading were determined by visual inspection of the degree of red change in the black printed area. 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.
