'This should be the mechanical noise at the time of electricity: output, and,' Leaving a few devices, because there is almost no printing low, so most of the operating cost meter when the spray brush wheel is used. It is a relatively low-cost ^ 17 meter. Because this inkjet type is also used to make full-color printing for the manufacture of personal louvres, it has always been due to black-sprayed images, or advertising and Kanban is a dye-based ink, so ^ ^ The ink used in the meter will fade, or due to moisture and: = Kanban: At the time, the ink has the disadvantage of the so-called unrecognizable image. Losing images, describing such shortcomings, therefore, the system proposes: f: In order to improve the ink used in inkjet printers. Because the color: ink is used as a financial and weather-resistant material, even the image printed on the inkjet printer will have Yes, the image will not be caused by fading and indoor humidity.

However, as mentioned above, with the improvement of the water resistance and weather resistance of inks, especially for applications such as advertisements and signboards, the weather resistance of inkjet recording materials is also required. Therefore, a recording material is used. The film is used as printing paper, and the recording film is provided on the surface of a substrate film composed of a plastic film with the ink receiving layer composed of a hydrophilic polymer substance. Up to now, it has been proposed that at least two layers be provided on a support composed of polyvinyl alcohol and polyvinyl chloralidone (Japanese Patent Publication No. 6-427). The ink-receiving layer of the ink-receiving layer uses a polyethylene resin layer, and the ink-receiving layer of the lower layer uses a water-soluble resin (Japanese Patent Laid-Open No. 5-2620 28). Bulletin), etc., as the ink receiving layer provided on the aforementioned base film. Although the ink-receiving layers described above have relatively good ink drying properties, printing characteristics, such as image reproducibility and color development properties, when the ink is a dye-based ink, the ink is a pigment. In the state of the ink, the so-called dryness of the ink is relatively low, and the ink cannot be fixed on the ink receiving layer. At the same time, when it comes into contact with the image surface, the image will peel off, and the ink will be lost. It has the disadvantage of ink penetration. In order to overcome these disadvantages, a recording film (Japanese Patent Laid-Open Publication No. 10-5 2 9 6 9) having a light transmittance of 50% or less has been proposed, and the light transmittance is 50 A recording film of% or less is attached to a substrate, and (A) a water-soluble tree is added in a specific ratio.

Crosslinking agent, and %% ^ " Ink-linking layer, is the crosslinking agent of the component), as the component. It should be used as the aforementioned (. There is no any; Limit: Crosslinking the component (A) of the adhesive "Urea and epoxy resin P" can also use known cross-linking agents. For example, lipids, B-amplified /, melamine resin, under the tree with a block of isocyanate group is best Use urea aldehydes, etc .; in the state where the adhesive is polyvinyl alcohol, it is compared with the oil black, then the above is described as follows: (Γ // eight of the adhesive component in the joint layer of the eight, the most cup is Yushi J Cheng The cross-linking agent of the knife is usually 3 ~ 20 weight " r ^ Xj X® FH ^ Ip * agent. It is (c) into the proportion of ~ 5 parts by weight in the ink. In the cross-linked state, the weight of the two-layered layer ′ in the ink-receiving layer is less than 1 part by 5 parts by weight, and the phase is sufficient to prevent the ink-receiving layer from the base film 531500.

V. Description of the invention (ίο) It was peeled off, and it was not able to exert an anvil force of 77 to exert the so-called water resistance rising effect and the crack prevention effect. It is said that the amount of ink receiving layer If it exceeds 15 parts by weight, it will result in a decrease in oil absorption of the double ink 丨 ^^ a ^ f77 〒. In the ink-receiving layer, the catalyst that is used as an essential component of the hafnium component can promote the reaction of the aforementioned cross-linking agent, and also according to the type of cross-linking agent used, by Xi Tian Among the known catalysts in the Zhizhixianke technology, the catalyst is appropriately selected and used. For example, ammonium chloride is suitable in the state of the crosslinking agent urea. The catalyst is usually used in the proportion of 20 to 100% by weight relative to the crosslinking agent.

In addition, when the catalyst as described above is added to the aforementioned bonding layer, the catalyst will not be fused to the bonding layer and the ink receiving layer, so that the layer body between the bonding layer and the ink receiving layer will not be fused. The phenomenon of peeling is relatively easy to occur and the (c) component in the bonding layer reacts with the (E) component in the ink-receiving layer to form a cross-linking phenomenon in order to exert the desired effect. The bonding layer in the inkjet recording film of the present invention can dissolve or disperse the aforementioned (A) component, (B) component, and (C) component in an aqueous solvent at a certain ratio, In addition, after preparing a coating solution having a solid content concentration of about 5 to 10% by weight, according to a general method, the aforementioned coating solution is coated on a substrate film or a pull-down layer provided as required. Then, a drying process is performed so that the bonding layer in the inkjet recording film of the present invention is not disposed. In addition, the 'ink-receiving layer' can dissolve or separate the aforementioned (A) component, (D) component, (C) component, and (E) component in a certain ratio, respectively.

Description of the invention (11) Scattered in an aqueous solvent, and after preparing a coating solution having a solid content concentration of about 5 to 25% by weight, according to a general method, on top of the aforementioned bonding layer, The aforementioned coating liquid is applied, and then a drying process is performed to facilitate the installation of the ink receiving layer. At this time, various coating liquids for forming a bonding layer and forming an ink fork layer may be added with various additives conventionally used in general, such as surfactants, lubricants, stabilizers, and coloring. Agent. The thickness of the bonding agent is about 5 ~ 15, and the thickness of the ink fork layer is usually in the range of 20 ~ 50vm, but it is preferably in the range of 25 ~ 40 // m Within range. In addition, in the present invention, bonding is provided on one side of the base film.

In the state of the layer and the ink-receiving layer, the ink-receiving layer has an anti-curving layer on the opposite surface. Based on the adhesive properties of the adhesive and the transportability in the printer to facilitate the formation of the aforementioned curling prevention systems, such as thermoplastic resins, thermosets, if more specific, acid, vinegar, polyester, and vinyl chloride Matte roughening agent, can be listed clay, kaolin, alumina, barium dioxide, magnesium hydroxide, calcium phosphate, and resins, polyurethane resins, greases, and benzoguanitoic acid / trimer system It can be provided with a roll on the back surface of the base film [and] as required, and a matte roughening agent and a stop layer used for lifting according to the requirement; as the aforementioned adhesive, and a resin , And photo-curable resins. Examples of y include acrylic resins and polyurethane resins. In addition, the examples include inorganic powders such as silica, zirconia, titanized titanium, zeolite, calcium carbonate, sulfuric acid, glass, acrylic resins, vinyl resins, and cyanuric acid / formaldehyde condensate.
