【表】DETAILED DESCRIPTION OF THE INVENTION The present invention uses an inkjet recording method in which characters and images are formed by flying minute droplets of ink, and records images with excellent color reproducibility, water resistance, gloss, etc. on a recording medium. The present invention relates to a method of forming In recent years, the inkjet recording method has been characterized by its high speed, high resolution, low noise, ease of multicolor printing, and great flexibility in recording patterns. It is rapidly becoming popular in many applications. In particular, it is attracting attention as a means of obtaining color hard copies for computer terminals, etc., by taking advantage of the fact that various ink liquids can be used and the recording pattern is highly flexible. Furthermore, the images formed by the multicolor inkjet method are comparable to those produced by normal multicolor printing, and when the number of copies to be produced is small, it is cheaper than the normal plate making method. Attempts are being made to apply it to the field of color photographic printing. In general, inkjet recording methods include a charge amount control method, a pressure vibration type such as an electric field control method, an electrostatic acceleration type in which ink is ejected electrostatically accelerated by a voltage between a counter electrode, and a pressure pulse method. There are on-demand pressure pulse type methods that push ink out, and ink mist methods that generate mist using ultrasonic vibrations, but in either case, a recorded image is obtained by attaching liquid ink droplets to a recording medium. It is. High-quality paper and coated paper used for general printing, baryta paper and resin coated paper used as the base for photographic printing paper, and transparent polymer films used as light-transmissive recording media for overhead projectors, etc. Because ink absorption is extremely poor, when used for inkjet recording, the ink may remain on the surface for a long time and may come into contact with parts of the device, be touched by the operator, or sheets ejected in succession may overlap. If the recording surface is rubbed, the residual ink may stain or bleed the image, making it difficult to obtain a clear image. Therefore, it has been practically impossible to make clear ink jet recordings on these recording media using conventional water-based inks. If a highly volatile oil-based ink is used, the image dries quickly, so the above-mentioned disadvantages do not occur, but it is not preferable in terms of odor, toxicity, etc. Therefore, when recording using the inkjet recording method, ink, especially water-based ink, has good absorbency, and ink droplets adhering to the recording medium are quickly absorbed into the ink receiving layer, resulting in an apparently dry state. Furthermore, the recording medium is required to ensure that the diameter of the absorbed ink dots does not become larger than necessary. Furthermore, as printers and plotters for computer terminals began to produce various color hard copies, inkjet images could be obtained on transparent films that could also be used as recording media for optical projection types such as overhead projectors, and photographic prints became available. There has been a demand for inkjet recording media with glossy surfaces, such as multicolor printing on paper or coated paper. In general, an ink-absorbing ink-receiving layer needs to have many voids to absorb and retain ink, so an ink-receiving layer with many voids naturally has many interfaces with air and has a surface with microscopic irregularities. It reflects light diffusely and prevents it from passing through, making it less glossy and opaque. Furthermore, since it becomes difficult for light to reach the ink that has penetrated into the voids, the colors of the image become whitish and the color reproducibility and color density decrease. The present invention was achieved as a result of various studies on methods for creating clear inkjet recorded images on transparent or opaque recording media. A highly absorbent receiving layer is provided, ink is jetted by an inkjet device to form a recorded image on the ink receiving surface, and then a solvent for the thermoplastic organic polymer is applied to the ink receiving layer. The present invention provides a method for processing a recording medium that eliminates voids in an ink-receiving layer and forms a transparent film in which ink is trapped in the layer. The present invention will be explained in detail below. Supports used in the present invention include polyester, polysulfone, polyvinyl chloride, polycarbonate, polystyrene, polymethyl methacrylate,
Transparent films such as cellulose acetate, polyethylene, and polypropylene, or white films filled with white pigment or finely foamed, as well as opaque sheets such as general paper, coated paper, baryta paper, resin-coated paper, and metal foil. A similar substance is used. Examples of white pigments filled in the paper layer or film layer include titanium oxide,
Calcium sulfate, calcium carbonate, silica, clay, talc, and many other materials that are commonly used as fillers, pigments for paints, and kneading can be used. There are no particular limitations on the thickness of these supports, but those of 10 μm to 300 μm are usually used. In order to improve the adhesion between the film and the ink-receiving layer, it is also possible to apply general treatments to improve adhesion such as corona discharge treatment and flame treatment, or to provide a subbing layer. In this case, a resin layer such as gelatin or nitrocellulose is usually used as the subbing layer. The ink-receiving layer provided on the support is easily obtained by coating and drying a layer containing a thermoplastic organic polymer in the form of fine particles as a main material and adding an appropriate amount of adhesive in order to provide ink-absorbing ability. The composition of the fine particulate thermoplastic organic polymer includes, for example, polymonovinylidene aromatics such as polystyrene, polymethylstyrene, polymethoxystyrene, and polychlorostyrene, polyvinyl chloride, polyvinyl-cyclohexane, polyethylene, polypropylene, and polyvinylidene chloride. α of polyolefins and polyhaloolefins such as polymethacrylate, polychloroacrylate, polymethyl methacrylate, etc.
These are esters of β-ethylenically unsaturated acids and copolymers thereof. The particulate thermoplastic organic polymer used in the present invention is preferably a so-called slurry-like plastic pigment prepared by emulsion polymerization from one or more vinyl monomers, a dried product thereof, and a solid plastic pigment. It can be obtained as a fine powder or a powder formed into fine particles by pulverizing it by various means. The size of these thermoplastic organic polymer fine particles is usually 0.01 μm to 50 μm in diameter, preferably 0.05 μm to 30 μm, so that voids necessary for absorbing ink can be formed in the ink receiving layer. In the present invention, these organic fine particles are used as the main pigment, and 2 parts to 30 parts, preferably 5 parts to the normal pigment.
The mixture is mixed with about 20 parts to 20 parts of adhesive, dispersed in water or a suitable solvent, applied as a coating material onto the support, and dried to form an ink-receiving layer. Adhesives used in the ink receiving layer include:
For example, starches such as oxidized starch, etherified starch, esterified starch, and dextrin, cellulose derivatives such as carboxymethyl cellulose and hydroxyethyl cellulose, casein, gelatin, soybean protein, polyvinyl alcohol and its derivatives, maleic anhydride resin, and ordinary styrene. Conjugated diene polymer latex such as butadiene copolymer, methyl methacrylate-butadiene copolymer, acrylic polymer latex such as polymer or copolymer of acrylic acid ester and methacrylic acid ester, ethylene vinyl acetate copolymer, etc. Vinyl polymer latexes, functional group-modified polymer latexes made from monomers containing functional groups such as carboxyl groups of these various polymers, and thermosetting synthetic resin adhesives such as melamine resins and urea resins are used. It will be done. It is also possible to use cationically modified starch, polyvinyl alcohol, and various nitrogen-containing cationic resins in combination. Furthermore, if necessary, pigment dispersants, thickeners, flow modifiers, antifoaming agents, foam inhibitors, mold release agents, coloring agents, etc. may be appropriately blended without any problem. Coating machines include blade coaters, air knife coaters, roll coaters, brush coaters, curtain coaters, chamber coaters, bar coaters, gravure coaters, etc. that are generally used in the production of pigment-coated paper. can also be applied. After coating, the coating layer is dried by various conventional drying methods such as gas heater, electric heater, steam heating heater, hot air heating, etc. to form a coating layer. In this case, it is necessary that the temperature applied to the coating layer be below the melting point of the thermoplastic organic polymer fine particles used. If the coating layer is dried to a temperature higher than the melting point of the organic pigment, the organic pigment will fuse and form a film, which will reduce the ink absorbency, which is an important element of the ink-receiving layer. The coating layer may be applied in the required amount at one time, or it is possible to obtain the necessary suitability by overcoating it two or more times. Various methods have been developed for the method of applying ink into the ink-receiving layer in the present invention, that is, as inkjet recording devices, such as pressure vibration type, electrostatic acceleration type, and pressure pulse type. If it is possible to make the particles fly as minute droplets or mist and attach them to a predetermined position on the recording medium, that method is applicable.
There are no particular restrictions on the type of ink liquid. However, as the coloring dye in the ink liquid used, water-soluble direct dyes, acid dyes, basic dyes, etc. are generally suitable for use. When an ink-receiving layer of thermoplastic organic polymer fine particles is provided on a support and characters or images are recorded on the ink-receiving layer with an inkjet recording device, the ink-receiving layer has many voids. The image is white and opaque. In the present invention, a solvent for the thermoplastic organic polymer is applied to the ink-receiving layer having the inkjet recorded image, thereby dissolving and welding the thermoplastic organic polymer fine particles to form a film and changing it into a transparent layer. A process is necessary. As a method of applying a solvent to the ink receiving layer,
After inkjet recording, the ink-receiving layer can be directly coated with a solvent, applied by spraying, immersed in a solvent bath, or sprayed with a solvent from a specially provided nozzle during or after inkjet recording to adhere the ink. There is a method of attaching a solvent to the ink-receiving surface that has not been used or to the part where the ink is attached. The thermoplastic organic polymer fine particles in the ink-receiving layer to which the solvent is applied dissolve, forming a transparent film while trapping the inkjet recorded image. The film is then preferably fixed by removing the solvent. The solvent can be removed by vaporizing the solvent or by absorbing it into a support. At this time, it is effective to use auxiliary means such as heating, depressurization, and blowing air to reach the goal more quickly. Furthermore, it is also possible to give the surface of the molten resin a desired gloss or unevenness by pressing it against a surface or roll carved with a mirror, rough, or special pattern, or by applying light pressure. Furthermore, it is recommended that the ink-receiving layer contain ultraviolet absorbers, antioxidants, mold release agents, stabilizers, etc., which are usually used in thermoplastic resins, or that they be added together with solvents, which will improve the formed thermoplastic resin. It is desirable to prevent deterioration of the molecular film and to improve the weather resistance of dyes in inkjet images. The term "solvent" used in the present invention refers to an organic solvent that has the effect of dissolving the water-insoluble thermoplastic organic polymer fine particles used in the present invention, making at least their surfaces fluid, and adhering them to each other, thereby reducing the interface between them. . Typical examples include aliphatic hydrocarbons such as gasoline, benzine, and petroleum naphtha, aromatic hydrocarbons such as benzene, toluene, and xylene, trichlorethylene, perchlorethylene, chloroform, carbon tetrachloride, ethylene trichloride, Halogenated hydrocarbons such as benzene monobromide and benzene dichloride,
amyl alcohol, isopropyl alcohol, 2
- Alcohols such as ethylhexyl alcohol, cyclohexanol, methyl amyl alcohol, benzyl alcohol, butyl alcohol, acetone, acetonylacetone, diisobutyl ketone,
Ketones such as diethyl ketone, methyl amyl ketone, methyl butyl ketone, methyl cyclohexanone, methyl ethyl ketone, methyl isobutyl ketone, methyl propyl ketone, medicyl oxide, acetate esters, butyrate esters, propionate esters, formate esters, butyl lactate,
Alcohol esters such as isopropyl lactate, ethyl lactate, ethyl oxypropionate, diethyl maleate, ketone esters such as ethyl acetoacetate and ethyl pyruvate, isopropyl ether, ethyl ether, diethyl carbitol,
Ethers such as diethyl cellosolve and butyl ether, ketone alcohols such as acetonylmethanol, diacetone alcohol, dihydroxylacetone, pyruvyl alcohol, isopropyl cellosolve, carbitol, glycidol, cellosolve, glycol ether, benzyl cellosolve, butyl carbitol, Ether alcohols such as butyl cellosolve, methyl carbitol, methyl cellosolve, triethylene glycol monoethyl ether, ketone ethers such as acetal ethyl ether, acetonylmethanol ethyl ether, methyl ethoxyethyl ether, butyl carbitol acetate, butyl cellosolve acetate, Examples include ester ethers such as carbitol acetate, cellosolve acetate, 3-methoxybutyl acetate, tylcarbitol acetate, and methyl cellosolve acetate. Alternatively, a mixture of these can be used as a solvent,
It is also effective to use a mixture when it is necessary to adjust the drying speed, etc. After inkjet recording on the ink-receiving layer made of thermoplastic organic polymer fine particles and adhesive formed on the support, a solvent is applied to the recording medium, which is then subjected to dissolution treatment. A transparent and glossy inkjet image medium with excellent color reproducibility and color density, excellent water resistance and light resistance can be obtained. In the present invention, when a transparent polymer film is used as a support, an inkjet image is obtained as a completely transparent film-like recording medium, which is excellent as an original for an overhead projector. In addition, when coated paper coated with white pigment, opaque synthetic paper, high-quality printing paper such as Paraiter paper or resin-coated paper, or photographic support is used as a support, the inkjet image will appear glossy on the opaque support. It is obtained as a film and is excellent as a recording medium that provides a highly glossy image with excellent color reproducibility, color density, and resolution. Furthermore, if you use a support that has a silky, fine-grained surface, etc. known in the photographic industry, you can obtain a surface equivalent to that, and when forming the ink-receiving layer into a film, you can also use a patterned surface. If the ink jet is pressed against the ink jet, it is possible to obtain an inkjet recorded image with a corresponding patterned surface. The present invention will be described below with reference to examples, but it is not limited to these examples. Note that parts and percentages shown in the examples mean parts by weight and percentages by weight. Example 1 A corona-treated 75 μm polyester film was coated with 5 parts of polyvinyl alcohol (PVA117 manufactured by Kuraray Co., Ltd.) as an adhesive, 50 parts of L-8801 (polystyrene plastic pigment manufactured by Asahi Dow) as thermoplastic organic polymer fine particles, and water. A paint consisting of 95 parts was applied to a solids content of 15 g/m 2 and dried.
This was used as a recording medium to record an image using an inkjet device, and then m-xylene was sprayed onto it and air-dried. The ink receiving layer became a transparent film. The inkjet image formed on the transparent film was clear and had high resolution, and was sufficiently satisfactory as a manuscript for an overhead projector. Example 2 A photographic support with a transparent polyethylene layer on the back side of base paper and a titanium-containing polyethylene layer on the front side was coated with 2 parts of styrene-butadiene copolymer latex as an adhesive and thermoplastic organic polymer fine particles. A paint consisting of 50 parts of LYTRON RX-1259 (polystyrene plastic pigment manufactured by Monsanto) and 98 parts of water was applied to a solid content of 20 g/m 2 and dried in a hot air dryer at 105°C. This was used as a recording medium to record an image using an inkjet device, and then immersed in a toluene bath for 3 seconds, taken out and air-dried. The inkjet images formed on the support were sharp and of high resolution, resulting in a recording medium similar to glossy photographic paper, with high color density and a highly glossy surface.
