【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inkjet recording sheet, and in particular, to a support, in which a layer containing a water-resistant water-soluble polymer and a non-water-resistant water-soluble polymer is provided as an inkjet recording layer. The present invention relates to an inkjet recording layer that has high density and resolution, good color reproducibility in multicolor recording, and excellent water resistance of the recording layer. Inkjet recording is noiseless, can perform high-speed recording, and can use plain paper, so it has been adopted in terminal printers and has become rapidly popular in recent years. Furthermore, by using a large number of ink nozzles, it is easy to perform multicolor recording, and multicolor recording using various inkjet recording methods is being considered. The paper used for these inkjet recordings is high-quality paper, continuous slip paper, or paper that absorbs a little more ink than the above-mentioned paper, as in the case of single-color recording such as with a terminal printer, recording is made only once in the same place on the paper. It is sufficient to use paper with good properties, and inkjet recording can be performed without any particular problems. However, in the case of multicolor inkjet recording, ink is ejected from two or more inkjet nozzles, and two or more ink dots often overlap at one point on the paper surface, resulting in a large amount of ink used per unit area. When recording with multicolor inkjet on paper with added sizing agents such as high-quality paper, art paper, and pigment-coated paper such as coated paper, the ink may be damaged due to poor ink wetting and insufficient absorption capacity, that is, poor ink absorption. The ink flows out from the point where it collides with the paper surface, mixture of different color inks, stains on the white background area due to ink scattering, stains due to contact with the paper surface after recording, etc. occur. Therefore, papers with poor ink absorption properties, such as high-quality paper, art paper, and coated paper, are completely impractical for multicolor inkjet recording. To perform multicolor inkjet recording, first of all, a recording paper with good ink absorbency is required. Paper-like paper made to a low density without adding sizing agents,
Since the ink wets well and there are many voids in the paper layer, the ink absorbing capacity is large, and the ink absorbency is sufficient for multicolor inkjet recording.
However, with such paper, the ink spreads in the lateral direction and penetrates into the thickness direction. If the spread of the ink in the horizontal direction is large, the resolution will be low, and if the penetration in the thickness direction is large, the ink will exist deep in the paper layer, and the density will decrease due to scattering of light by the voids in the paper layer above. The color becomes low and whitish. Furthermore, when recording in four colors of cyan, magenta, yellow, and black, the previously ejected ink penetrates deeply into the paper layer, making it difficult to see the colors from above and resulting in poor color reproducibility. Therefore, such paper with good ink absorbency prevents ink from flowing out, mixing colors, and scattering even in multicolor inkjet recording, but has low density and resolution, and poor color reproducibility, making it difficult to perform multicolor inkjet recording. In particular, clear images cannot be obtained in halftone reproduction multicolor inkjet recording. JP-A No. 52-73012, JP-A No. 52-74340, and JP-A No. 53-49113 are all attempts to minimize ink spreading and penetration without reducing ink absorption as much as possible. However, reducing ink absorption and ink spreading and penetration are contradictory properties, and if the ink absorption is set to a range sufficient for multicolor inkjet recording, it is possible to avoid an increase in ink spread and penetration. Nakatsuta. Since the inkjet recording paper according to these inventions is based on the assumption that ink is absorbed into the paper layer, it is not possible to obtain clear images with high density and resolution and good color reproducibility. It could not be used for multicolor inkjet recording. In multicolor inkjet recording, in order to obtain images with high density, high resolution, and good color reproducibility, it is necessary to minimize the spread of ink in the lateral direction, to ensure that the ink exists as much as possible on the surface of the paper layer, and to prevent ink flow and color mixing. Inkjet recording paper is required to have the contradictory properties of not causing scattering. As described in JP-A-55-146786 and JP-A-56-80489, an inkjet recording sheet in which a water-soluble polymer layer is provided on a support is used to make the recording layer soluble in water by the jetted water-based ink. Polymers rapidly swell or dissolve, causing ink to flow, color mixing,
Splashing is prevented. In addition, swelling or dissolution of the water-soluble polymer suppresses the lateral spread of the water-based ink and its penetration into the thickness, resulting in
Images with high resolution and excellent color reproducibility in multicolor recording can be obtained. However, such inkjet recording sheets have the disadvantage that when exposed to water or immersed in water, the inkjet recording layer lacks water resistance, and the recording layer peels off, causing the image to disappear. It is possible to make the inkjet recording layer water resistant by making the water soluble polymer water resistant with a crosslinking agent or other water resistant agent. However, if the water-soluble polymer is made even slightly waterproof, the rate of swelling or dissolution of the water-soluble polymer coating layer by the water-based ink will be extremely reduced, causing ink to run out, color mixing, and scattering. A satisfactory record could not be obtained with multicolor recording. An object of the present invention is to obtain an inkjet recording layer which is free from ink flow, color mixing, and scattering, has high density and resolution, has excellent color reproducibility, and has excellent water resistance. By providing an inkjet recording layer containing a water-resistant polymer and a non-water-resistant water-soluble polymer on a support, the inventors have discovered that the flow of ink, color mixing, scattering, density, resolution, etc. To successfully obtain an inkjet recording sheet whose inkjet recording properties such as color reproducibility are as good as conventional inkjet recording sheets coated with a water-soluble polymer, and whose inkjet recording layer has excellent water resistance. A recording layer coated with only a water-soluble polymer has excellent inkjet recording properties, but the recording layer does not have water resistance. A recording layer coated with a water-resistant water-soluble polymer has excellent water resistance, but has poor inkjet recording properties, making it impossible to obtain a satisfactory image, especially in multicolor recording. However, in a recording layer containing a water-resistant polymer that has been made water-resistant and a water-soluble polymer that has not been made water-resistant, the water-soluble polymer that has not been made water-resistant is swollen or dissolved by the water-based ink.
No ink flow, color mixing, or scattering, high density, high resolution, and good color reproducibility. In addition, the water-soluble polymers in the recording layer that have not been made water-resistant are embedded in a matrix of water-soluble polymers that have been made water-resistant, so they are not eluted by water and the recording layer has excellent water resistance. . The water-soluble polymers used in the inkjet recording sheet of the present invention include Japanese starch, potato starch, cornstarch, konjac, funori, agar, sodium alginate, molasses, gum tragacanth, gum arabic, locust bean gum, guar gum, Pectin, carrageenan, glue, gelatin, casein, soy protein, oxidized starch, dextrin, starch phosphate, carboxymethylated starch, hydroxyethylated starch, cyanoethylated starch, acrylic acid grafted starch, cationic starch, methylcellulose, hydroxyethylcellulose, Carboxymethyl cellulose, cellulose sulfate, cyanoethyl cellulose, polyvinyl alcohol, carboxylated polyvinyl alcohol, polyvinyl methyl ether, sodium polyacrylate, partially saponified polyacrylic ester, methyl vinyl ether-maleic anhydride copolymer,
Ethylene-maleic anhydride copolymer, styrene-

These water-soluble polymers are contained in the inkjet recording layer in a water-resistant or non-water-resistant form. It is desirable that the viscosity of the water-soluble polymer that is not made water resistant is high in terms of preventing ink from flowing out, but it is better not to be too high in terms of coating suitability. The preferred viscosity range is 5-5000 cps in a 5% aqueous solution. More preferably, it is 10 to 100 cps. Generally, it is desirable to coat a water-soluble polymer in combination with a pigment to impart properties such as ink water absorbency, anti-stickiness, and whiteness to the inkjet recording layer. Pigments to be applied in combination with water-soluble polymers include clay, talc, calcium carbonate, barium sulfate, zinc oxide, titanium white, synthetic silicate, silica, diatomaceous earth, polyethylene fine powder,
Polystyrene fine powder, urea resin fine powder, etc. are used. The appropriate mixing ratio of pigment to water-soluble polymer is 0 to 10 parts by weight per 1 part by weight of water-soluble polymer. Other additives to the coating solution that forms the inkjet recording layer include latex such as SBR to improve adhesive strength, and auxiliary agents to further improve wetting and water absorption of the water-soluble polymer coating layer by the water-based ink. Wetting and water-absorbing agents such as glycerin, polyethylene glycol, pyrrolidones, surfactants, water-absorbing gels such as polyacrylamide gel and starch gel, dyes for color adjustment such as blue tinting, pigments, fluorescent dyes, and the light resistance of ink. Ultraviolet absorbers, pigment dispersants, antifoaming agents, lubricants such as calcium stearate, antifungal agents, etc. can be used depending on the purpose. The method for providing an inkjet recording layer containing a water-resistant water-resistant polymer and a non-water-resistant water-soluble polymer on a support is not particularly limited, and for example, the following methods can be adopted. . (1) A method of coating a support with a coating liquid containing a water-soluble polymer, its water-resistant agent, and another water-soluble polymer that does not react with the water-resistant agent. (2) A method of coating a support with a coating liquid containing a water-soluble polymer having a crosslinking group that self-crosslinks without reacting with the water-soluble polymer. (3) A coating solution containing two or more water-soluble polymers is applied to a support, and one of the water-soluble polymers is made water-resistant, but the other water-soluble polymer is not made water-resistant. A method in which a curing agent is applied onto a water-soluble polymer layer. (4) After applying two or more types of water-soluble polymers,
One of these is caused by irradiation with ultraviolet rays, electron beams, etc.
A method for making various types of water-soluble polymers water-resistant. If necessary, a sensitivity improver for crosslinking agent irradiation may be added to the coating liquid. (5) A coating liquid containing a water-soluble polymer that does not become water-resistant when heated and a volatile acid or alkali to form a salt, and the water-soluble polymer that becomes water-resistant when the acid or alkali evaporates when heated is applied to the support. Method. As a water-resistant agent that makes water-soluble polymers insoluble,
Various types of polymers that react with water-soluble polymers through salt bonds, coordinate bonds, covalent bonds, hydrogen bonds, etc. to become insolubilized can be used. For water-soluble polymers with anionic dissociative groups such as carboxyl groups and sulfonic groups, water-soluble metal salts such as aluminum chloride, aluminum sulfate, calcium chloride, calcium acetate, zinc chloride, and zirconium acetate, and cationic surfactants are recommended. agent,
Cationic polyelectrolytes can be used. For water-soluble polymers with cationic dissociative groups such as amino groups and quaternary ammonium groups, low-molecular anionic substances such as fatty acids, tannic acid, tartarite, anionic surfactants, and anionic polymers are recommended. Molecular electrolytes can be used. For water-soluble polymers having amino groups and hydroxyl groups, formalin, glyoxal, glutaraldehyde, melamine resin, urea resin, epoxy compound, isocyanate, cyanuric chloride, polyethyleneimine, polyamide-polyamine-epichlorohydrin resin, dialdehyde starch, Epoxy compounds can be used for water-soluble polymers having free carboxyl groups, and polycarboxylic acids can be used for polyvinylpyrrolidone and polyethylene oxide. The combination of a water-resistant agent and a water-soluble polymer takes advantage of the difference in reaction mechanism and reaction rate between the water-resistant agent and the water-soluble polymer, and makes sure that at least one type of water-soluble polymer becomes water-resistant. , it is necessary to select at least one type of water-soluble polymer so as not to make it waterproof. The ratio of water-soluble polymeric substances that have been made water-resistant and water-soluble polymeric substances that have not been made water-resistant varies depending on the characteristics of the substances used, such as the degree of water solubility, etc.
Generally, a suitable ratio of the former to the latter is in the range of about 10:1 to about 1:2. Examples of self-crosslinking water-soluble polymers in which the water-soluble polymer itself has a water-resistant function include methylol starch, methylolated polyacrylamide, dialdehyde starch, polyethyleneimine, polyamide-polyamine-epichlorohydrin resin, and epichlorohydrinated polydimethylaminoethyl. Methacrylate, etc. can be used. Examples of water-soluble polymers that become water-resistant by volatilizing acids or bases when heated include ammonium salts of casein, ammonium salts of styrene-maleic anhydride copolymers, ammonium salts of isobutylene-maleic anhydride copolymers, and vinyl acetate. - Ammonium salt of crotonic acid copolymer, acetate of polydimethylaminoethyl methacrylate, etc. can be used. Paper, paper,
Cloth, plastic film, metal plates, wood plates, glass plates, etc. can be used. The paper used for the support of the present invention is mainly made of wood pulp, but if necessary, synthetic fibers, synthetic pulp, inorganic fibers, etc. may be mixed therein. Additives include rosin, alkyl ketene timer, sizing agents such as alkenyl succinic acid, fillers such as clay, talc, calcium carbonate, polyacrylamide,
A paper strength agent such as starch, a fixing agent such as sulfate, a cationic polymer, a wet strength improver such as a melamine resin, a polyamide-polyamine-epichlorohydrin resin, a dye, a fluorescent dye, etc. may be internally added. During paper making, water-soluble polymers such as starch and polyvinyl alcohol are
A sizing agent such as sodium salt of styrene-maleic anhydride copolymer alkyl ester may be applied. The coating amount of the water-soluble polymer coating layer is suitably 0.5 to 10 g/m 2 on one side, particularly 2 to 5 g/m 2 in terms of the solid content of the water-soluble polymer. If the viscosity of the water-soluble polymer that is not made water resistant is low, it is necessary to increase the amount of coating, and if the viscosity is high, the amount of coating can be reduced. In general, if the coating amount is small, the viscosity of the aqueous ink will not increase sufficiently, causing ink to flow, color mixing, and scattering, resulting in a low density. As the coating device used for coating the water-soluble polymer, air knife coaters, blade coaters, bar coaters, gravure coaters, curtain coaters, size presses, roll coaters, etc., which are generally used for coating paper, can be used. After the water-soluble polymer coating solution is applied and dried, it is desirable to smooth the coated surface using a machine calender, gloss calender, super calender, or the like. Ink used for inkjet recording is often aqueous ink, and the inkjet recording sheet of the present invention is also used for inkjet recording using aqueous ink. The water-based ink that can be used in the inkjet recording sheet of the present invention is, for example, JP-A No. 47-12105
