2. Description of the Related Art Conventionally, when a development drawing, a design drawing, or the like is created, an operation of recording the recording material on a recording material with a pen or an ink jet plotter, and then performing color classification is performed. For example, in the case of a development map, this color coding is used to make the current situation and the future forecast map easy to understand, and in the case of a map, etc., it is performed to make it easy to understand by color coding addresses, sections, etc. It is. This operation has been performed manually after recording with a pen plotter, an ink jet plotter, or the like, and the workability and productivity have been extremely low.

Therefore, in recent years, this color classification work has been performed using a computer. In this computer-based color-coding work, first create a place to be color-coded with a computer, record the information color-coded by an output device, for example, an inkjet printer or an inkjet plotter, based on the information, and then use a pen plotter to Record information. As a result, work efficiency and productivity are dramatically improved as compared with the conventional manual operation. As a recording material used at this time, a recording material in which an ink receiving layer composed of a hydrophilic polymer substance and a roughening forming agent is provided on a base film is used (JP-A-7-195894).

[0004] However, in the conventional recording material, after recording a color-coded pattern by an ink jet system, if a pen plotter is used to record necessary information,
In particular, blurring or discontinuity of the image occurred, and it was extremely difficult to record necessary information with a pen plotter. In addition, when improvement in writing performance by a pen plotter is required, it is inevitable that the reproducibility and coloring of a pattern recorded by the ink jet method are reduced.

[0005]

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The substrate film used in the aqueous ink recording film of the present invention is not particularly limited, and those conventionally used as substrates in conventional recording films, for example, polyethylene terephthalate, polyethylene, polypropylene, It can be appropriately selected from polyamides and the like according to applications, and among them, polyethylene terephthalate is preferred. In particular, when used for an overhead projector, a transparent one is preferable. The thickness of the base film is usually 2
It is in the range of 5-250 μm, preferably 50-150 μm.

In the water-based ink recording film of the present invention, an ink receiving layer is provided as a layer (A) of the recording layer on one side of the base film. In order to improve the adhesion, an undercoat layer may be provided between the base film and the ink receiving layer, if desired. As the undercoat layer, a saturated polyester resin, a urethane resin, or the like is usually used, but a urethane resin is particularly preferable because of good adhesion to the ink receiving layer. The coating amount of the undercoat layer is usually 3
１５15 g / m ² .

The ink receiving layer of the layer (A) comprises (a) polyvinyl alcohol, (b) polyvinyl pyrrolidone,
(C) a layer mainly composed of an inorganic roughening forming agent and (d) a cross-linking agent, and the polyvinyl alcohol as the component (a) has a polymerization degree of usually 1,000 or more, preferably 1,000 to 1,000.
Those having a range of 3000 are used. When the degree of polymerization is 10
If less than 00, ink drying property of the film (ink absorption)
And water resistance may be insufficient. The polyvinyl alcohol is preferably a partially saponified or completely saponified polyvinyl acetate having a saponification degree of 75 mol% or more, particularly preferably a partially saponified compound having a saponification degree of 75 to 90 mol%. If the degree of saponification is less than 75 mol%, the ink absorption rate is undesirably low.

The polyvinyl pyrrolidone as the component (b) generally has a molecular weight of 40,000 or more, preferably 60 or more.
Those having a range of 0000 to 2800000 are used.
When the molecular weight is less than 40,000, the absorption rate and receptivity of the aqueous ink become insufficient, and as a result, the drying property of the ink decreases.

The content ratio of component (a) to component (b) is preferably in the range of 9: 1 to 4: 6 by weight.
If the content of the component (a) is more than this range, the drying property of the ink may be reduced. If the content is less than this range, the water resistance of the film may be reduced and stickiness may be caused. From the viewpoints of ink drying property and water resistance of the film, the preferable content ratio of the component (a) and the component (b) is in the range of 7: 3 to 5: 5 by weight.

Next, as the inorganic roughening forming agent of the component (c), a synthetic silica powder having an average particle diameter of about 2 to 6 μm and a calcium carbonate powder having an average particle diameter of about 0.8 to 1.8 μm are used. Combinations are used. Examples of such a combination include a combination of a synthetic silica powder having an average particle diameter of about 3.5 μm and a calcium carbonate powder having an average particle diameter of about 1.4 μm, and a synthetic silica powder having an average particle diameter of about 6 μm and about 3.5 μm. A combination of the mixture with a calcium carbonate powder having an average particle size of about 1.4 μm is exemplified.

As the inorganic surface roughening agent, a synthetic silica powder and a calcium carbonate powder are preferably used in a weight ratio of 8: 2 in view of improving ink drying property, ink absorption property, coloring property and writing property. To 4: 6, preferably 7: 3 to 5: 5, particularly preferably about 6: 4. It is preferable to use an inorganic roughening agent having a large surface area if the particle diameter is the same. By using a material having a large surface area, ink absorbability and writing properties can be improved. For example, a synthetic silica powder has a surface area of 500 to 800 m ² /
g of calcium carbonate powder, and the surface area of the calcium carbonate powder is preferably 15,000 to 30,000 m ² / g. In addition, by using particles having different particle diameters, the dot shape in the ink jet method can be made close to a perfect circle, and the writing property with a pen plotter, especially the reproducibility of a fine image can be improved. .

The content of the inorganic roughening agent (C) in the ink receiving layer is preferably in the range of 30 to 150% by weight based on the total weight of the components (A) and (B). . If the amount is less than 30% by weight, the reproducibility of fine lines and water resistance with a pen plotter will decrease, and if it exceeds 150% by weight, clogging and blurring of the pen plotter will easily occur, and furthermore, dot bleeding with an ink jet plotter will occur. Occurs. From the viewpoints of reproducibility and writability of fine lines with a pen plotter, image forming properties with an ink jet plotter, and water resistance, the preferred content of the component (c) is
50 to 1 based on the total weight of component (a) and component (b)
It is in the range of 20% by weight, especially in the range of 70 to 100% by weight.

On the other hand, a urea resin is preferable as the crosslinking agent of the component (d) in the ink receiving layer. By using this urea resin, an appropriate amount of a crosslinking agent can be easily added to the polyvinyl alcohol as the component (a), and desired water resistance can be obtained. The crosslinking agent of the component (d) is preferably used in a proportion of 5 to 12% by weight based on the component (a). If the amount is less than 5% by weight, the water resistance and writing properties will not be sufficiently improved, and if it exceeds 12% by weight, the ink absorbency will decrease. From the viewpoints of water resistance, writing properties and ink absorbability, it is advantageous to use the crosslinking agent of component (d) in a proportion of 6 to 8% by weight based on component (a).

In the present invention, a catalyst can be used together with the crosslinking agent of component (d), if desired. Examples of the catalyst include ammonium chloride, ammonium nitrate, and ammonium sulfate.
This catalyst is generally used in an amount of 1 to the crosslinking agent (d).
It is used in a ratio of 0 to 20% by weight. If the amount of the catalyst deviates from this range, the writing property and the image reproducibility with a pen plotter and an ink jet plotter cannot be sufficiently improved.

In the present invention, the component (A)
The component (b), the component (c) and the component (d) are dissolved or dispersed in an aqueous medium at a predetermined ratio, respectively, to prepare a coating solution having a solid content of about 10 to 15% by weight. The ink receiving layer as the layer (A) is provided by coating and drying according to a conventional method on the film or the undercoat layer provided as required. At this time, conventionally used various additives such as a surfactant, a lubricant, a stabilizer, and a coloring agent can be added to the coating liquid. The thickness of the ink receiving layer is usually 5 to 20 μm, preferably 6 to 1 μm.
The range is 5 μm.

In the present invention, a layer containing a dot shape adjusting agent is provided as a layer (B) on the ink receiving layer which is the layer (A) thus provided, and the layers (A) and (B) are provided. To form a recording layer. As the dot shape adjusting agent used in the layer (B), a quaternary ammonium salt type acrylic resin is used. Examples of the quaternary ammonium salt type acrylic resin include a copolymer salt of an alkyl acrylate or an alkyl methacrylate with a dialkylaminoalkyl acrylate or a dialkylaminoalkyl methacrylate. Such quaternary ammonium salt type acrylic resins are known. For example, a quaternary salt of a copolymer of butyl methacrylate and dimethylaminoethyl methacrylate having a molar ratio of 1: 1 is available as a commercial product.

In order to form the dot shape adjusting agent-containing layer (B), the dot shape adjusting agent is dissolved in an appropriate solvent, for example, alcohol or a mixture of alcohol and water, and this solution is used for forming the ink receiving layer. After applying on the top, it may be dried. At this time, the dot shape adjusting agent may be formed in a layer on the ink receiving layer, or may be partially dissolved or impregnated in the ink receiving layer.

The coating amount of the dot shape adjusting agent for the layer (B) is suitably in the range of 3 to 10 g / m ² . When the coating amount of the dot shape adjusting agent of the layer (B) is less than 3 g / m ² , the image clarity (image resolution) becomes insufficient, and the coating amount of the dot shape adjusting agent of the layer (B) is insufficient. If it exceeds 10 g / m ² , the ink absorbency and the ink drying property decrease. This (B) layer has the effect of forming the dot shape to a more perfect circle and further preventing the ink from bleeding.

In the water-based ink recording film of the present invention, it is necessary that the surface roughness of the recording layer thus formed is in the range of 0.8 to 1.5 μm. When the surface roughness is less than 0.8 μm, the writing property with a pen plotter is reduced, especially the density of the image is reduced, or the color developability of the image by the inkjet method is reduced, and
If it exceeds m, clogging of the pen tip and a decrease in writability, particularly blurring of image lines may occur, and reproducibility of an image in an ink jet system may decrease. From the viewpoints of writability with a pen plotter, color development and reproducibility of an image by an ink jet method, a particularly preferable range of the surface roughness is 1.0 to 1.5 μm.
It is. The surface roughness of a 2 × 5 cm sample was measured using a three-dimensional surface roughness profile analysis system Surfcom 570A-
Using 3DF (manufactured by Tokyo Seimitsu Co., Ltd.), the center line average roughness (R
The value of a) was measured five times, and the average value was shown.

The recording layer needs to have a standard number of wiping times of the surface of 150 to 1000 times. If the standard number of wipings is less than 150 times, part of the surface coating tends to penetrate the pen tip, causing clogging of the pen tip and blurring of the image. It becomes difficult to do. The standard number of times of wiping is particularly preferably in the range of 170 to 800 times in terms of pen writing properties and image forming properties. The standard number of wipes was determined by fixing a sufficiently moistened gauze to a peeling / slipping scratch tester (manufactured by HEIDON, trade name: HEIDON14) and applying a load of 323 g and a speed of 4000 mm / min to the recording layer surface. Is reciprocated, and peeling of the recording layer of 1 mm ² or more
This is the value obtained by measuring the number of times that the number of locations can be confirmed.

In the water-based ink recording film of the present invention, the back surface of the base film (the surface opposite to the recording layer)
If desired, an anti-curl layer can be provided. The anti-curl layer is formed of only a binder or a binder and a matting agent. Examples of the binder include a thermoplastic resin, a thermosetting resin, a photocurable resin, and the like. Resin, polyester resin and vinyl chloride resin. As the matting agent, for example, silica, zirconia, clay, kaolin, alumina, titania, zeolite, calcium carbonate, barium sulfate, magnesium hydroxide, calcium phosphate, inorganic powders such as glass, acrylic resin, urethane resin, Vinyl chloride resin, benzoguanamine resin,
Synthetic resin powders such as benzoguanamine / melamine / formaldehyde condensate are exemplified. The average particle size of the matting agent is in the range of 0.1 to 20 μm, preferably 2 to 10 μm. Further, when the ink receiving layer is also formed on the back surface of the base film, the same one as provided on the front surface of the base film may be provided, or the other, for example, does not contain a matting agent, Alternatively, a transparent ink receiving layer containing a very small amount may be provided.

By using the resin used for the recording layer, ie, the component (a) and the component (b), as the resin used for the curl prevention layer, the curl prevention effect is further improved. The thickness of the anti-curl layer is 1 to 10 μm,
Preferably, the range of 3 to 7 μm is advantageous. Further, the anti-curl layer may contain additives conventionally used as additives, for example, a surfactant, a lubricant, a stabilizer, and a colorant.

Next, the recording method of the present invention uses the aqueous ink recording film thus obtained, and first forms an image on the recording layer by using an aqueous ink by an ink jet method. Then use a pen plotter to add water

In this case, any of an inkjet printer system and an inkjet plotter system may be used.

Next, after forming an image on the aqueous ink recording film by the ink jet method in this way, necessary information is written by a pen plotter using the aqueous ink . The writing of this information can also be performed by, for example, creating an image in advance by a computer and outputting the information on the image formed by the ink jet method with a pen plotter through the computer.
