Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an ink receiving layer recordable by ink jet on one surface of a transparent substrate,
A pen plotter having a writing layer writable by a pen plotter on the other surface, a recording material for inkjet, and a pattern formed on both surfaces of the recording material by the inkjet and the pen plotter, The present invention relates to a recorded material in which each pattern can be seen through from each opposite surface of a recording material.

[0002]

2. Description of the Related Art In recent years, with the widespread use of computer technology, materials created by computers have been frequently printed out using a printer or the like. Printers used at this time include dot impact printers, laser printers, thermal printers, and inkjet printers.However, there is almost no mechanical noise at the time of printout, and the running cost associated with printout is low. Printers are often used. Normally, plain paper and coated paper are often used as the paper used when using this ink jet printer.However, an ink receiving layer made of a hydrophilic polymer substance is provided on the surface of a base film made of a plastic film. The provided recording film for inkjet is also used.

In such an ink jet recording film, the ink is absorbed into the ink receiving layer when recording by the ink jet method. Therefore, when the recorded image is partially corrected, the ink receiving layer is usually removed together with the ink receiving layer. Alternatively, a method of decoloring the ink absorbed in the ink receiving layer has been adopted.

[0004] However, when the ink receiving layer is removed, the substrate surface is exposed, and the removed portion is noticeable due to the difference in reflectance between the removed portion and the other ink receiving layer.
The appearance is inevitable. In recent years, there has been an increasing demand for rewriting after correction. However, in the conventional inkjet recording film, it is difficult to apply ink to the removed portion, so that the corrected image cannot be added to the removed portion with high accuracy. There were drawbacks.

[0005] On the other hand, when creating a development drawing or a design drawing, a work of recording on a recording material with a pen or an ink-jet plotter and then performing color coding is often performed. Have been doing it. 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. However, in a conventional ink jet recording material, after recording a color-coded pattern by an ink jet method, when recording necessary information with a pen plotter, blurring or breakage of an image particularly occurs, and the necessary information of the pen plotter is generated. It was often difficult to record.

On the other hand, a conventional ink jet recording film has an ink receiving layer made of a water-soluble or hydrophilic polymer in order to receive an aqueous ink as quickly as possible. The curl is generated due to the difference in the expansion coefficient of the layer, and when the curl occurs, the transportability in the printer is reduced, and the winding is smoothly performed by the apparatus that winds the recording film around the drum and records. This is disadvantageous in that recording is not possible.

[0007]

SUMMARY OF THE INVENTION Under such circumstances, according to the present invention, after printing or drawing by the ink jet method, correction and necessary information can be added by a pen plotter, and curling can be suppressed. A recording material that can be formed, and a recording material in which a pattern is formed on each surface of the recording material by an ink jet and a pen plotter so that the pattern can be seen through from each opposite surface. is there.

Is provided.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The transparent substrate used in the pen plotter and the recording material for ink jet of the present invention is not particularly limited, and those conventionally used as a substrate for a recording material, for example, polyethylene terephthalate, Any one of films such as polyethylene, polypropylene and polyamide can be selected and used, and among them, polyethylene terephthalate film is particularly preferable. The thickness of the substrate is usually 25 to
It is in the range of 250 μm, preferably 50-100 μm.

In the recording material of the present invention, an ink-receiving layer recordable by ink jet is provided as a layer (A) on one surface of the transparent substrate, and the adhesion between the ink-receiving layer and the substrate is improved. For improvement, an undercoat layer may be provided between the substrate 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 thickness of the undercoat layer is usually in the range of 0.5 to 1.5 μm.

Next, as the ink receiving layer of the layer (A),
As long as it can be recorded by inkjet,
There is no particular limitation, and examples thereof include those using a hydrophilic resin or a water-soluble resin as a binder, which is conventionally used for an ink receiving layer of a recording material for ink jet recording, and is excellent in ink absorbency, drying property and water resistance. In view of the above, a layer containing (a) polyvinylpyrrolidone, (b) polyvinyl alcohol or polyvinyl acetal or both, and (c) a particulate material as a main component is preferable.

The polyvinylpyrrolidone of the above-mentioned component (a) has a molecular weight of usually 40,000 or more, preferably 600 or more.
Those having a range of 000 to 2800000 are used. When the molecular weight is less than 40,000, the ink absorption rate and receptivity become insufficient, and as a result, the drying property of the ink decreases.

On the other hand, the polyvinyl alcohol used as the component (b) usually has a degree of polymerization of at least 1,000,
Preferably, those having a range of 1000 to 3000 are used. When the degree of polymerization is less than 1,000, the ink drying property (ink absorption property) and the water resistance of the film become insufficient. The polyvinyl alcohol has a degree of saponification of 7
A partially saponified or completely saponified polyvinyl acetate of 5 mol% or more is preferred, and a partially saponified product having a saponification degree of 75 to 90 mol% is particularly preferred. When the degree of saponification is less than 75 mol%, the ink absorption speed becomes low. Further, polyvinyl acetal is obtained by a reaction between polyvinyl alcohol and aldehyde, and usually has a degree of acetalization of 2
２０20 mol%, preferably 5 to 15 mol% is used. If the degree of acetalization is less than 2 mol%, sufficient water resistance cannot be obtained, and if it exceeds 20 mol%, although the water resistance is good, the ink drying property and the crosslinkability deteriorate.

In the present invention, as the component (b), the above-mentioned polyvinyl alcohol may be used, or a polyvinyl acetal or a mixture thereof with polyvinyl alcohol may be used. These polyvinyl alcohols and polyvinyl acetal are preferably cross-linked with a cellulose-reactive cross-linking agent or urea in order to further improve the water resistance. The cellulose-reactive cross-linking agent is a cross-linking agent having reactivity to hydroxyl groups of cellulose, such as dimethylol ethylene urea, dimethylol propylene urea, dimethylol alkyl triazone, methylated Cyclic or heterocyclic urea derivatives such as dimethyloluron and dimethylolglyoxal monourein; These react with functional groups in polyvinyl alcohol or polyvinyl acetal in the presence of a catalyst such as ammonium chloride, ammonium nitrate, ammonium sulfate or the like to form a three-dimensional structure. The cellulose-reactive crosslinking agent or urea is usually used in an amount of 4 to 12 parts by weight per 100 parts by weight of polyvinyl alcohol or polyvinyl acetal.
It is used in a proportion of 5 parts by weight, preferably 5 to 10 parts by weight. If the amount is less than 4 parts by weight, the effect of improving water resistance will not be sufficiently exhibited, and if it exceeds 12 parts by weight, the ink absorbency will decrease. The catalyst used in combination therewith is usually used in a proportion of 20 to 100% by weight based on the amount of the fibrin-reaction type crosslinking agent.

Further, the particulate matter used as the component (c) may be either inorganic or organic. Examples of the inorganic fine particles include powders of silica, zirconia, clay, kaolin, alumina, titania, zeolite, calcium carbonate, barium sulfate, magnesium hydroxide, calcium phosphate, and glass. Preferred among these are synthetic silica powder and calcium carbonate powder, which do not impair the dot shape and have excellent ink absorbency. Examples of the organic fine particles include powders of synthetic resins such as acrylic resins, urethane resins, vinyl chloride resins, benzoguanamine resins, and benzoguanamine / melamine / formaldehyde condensates. These particulate matter
Each may be used alone, or two or more kinds may be used in combination. In particular, it is preferable to use the synthetic silica powder and the calcium carbonate powder at a weight ratio of about 1: 1 because the ink drying property and the ink absorbing property are improved.

The fine particles of the component (c) preferably have an average particle diameter of 0.5 to 15 μm, preferably 0.8 to 9 μm. This average particle diameter is 0.5 μm
If it is less than 15 μm, the ink drying property is inferior.

Regarding the content ratio of the components (a), (b) and (c), the weight ratio of the components (a) and (b) is 1: 9 to 6: 4, preferably 2: 8. To 4: 6. If the amount of the component (a) is more than this range, the water resistance will be reduced, causing stickiness. If the amount of the component (b) is more than this range, the ink drying property (ink absorption) will be reduced. The component (c) is
30 to 1 based on the total weight of component (a) and component (b)
It is desirably in the range of 00% by weight, preferably 40-80% by weight. If the amount is less than 30% by weight, the ink drying property is poor, and if it exceeds 100% by weight, the water resistance of the coating film is reduced. The type and amount of the component (c) are preferably selected so that the ink receiving layer has transparency.

In the recording material of the present invention, (a)
The component, the component (b) and the component (c) are dissolved or dispersed in an aqueous medium at a predetermined ratio, respectively, to obtain a solid content of 10 to 10.
After preparing a coating liquid of about 15% by weight, the ink receiving layer as the (A) layer is provided by applying and drying according to a conventional method on a transparent substrate or an 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 in the range of 5 to 30 μm, preferably 10 to 20 μm.

In the recording material of the present invention, a dot shape adjusting agent-containing layer can be provided, if desired, on the ink receiving layer thus provided. The dot shape adjusting agent contained in this layer is preferably a quaternary ammonium salt type acrylic resin, a copolymer salt of alkyl acrylate or alkyl methacrylate with dialkyl amino acrylate or dialkyl amino alkyl methacrylate, or the like. Such quaternary ammonium salt type acrylic resins are known, for example, a molar ratio of butyl methacrylate to dimethylaminoethyl methacrylate of 1: 1.
The quaternary salt of the copolymer is commercially available.

In order to form the dot shape adjusting agent-containing layer, the dot shape adjusting agent was dissolved in a suitable solvent, for example, alcohol or a mixture of alcohol and water, and the solution was applied on the ink receiving layer. Then, it may be dried. At this time, the dot shape adjusting agent may be formed on the ink receiving layer, or may be partially dissolved or impregnated in the ink receiving layer.

The coating amount of this dot shape adjusting agent is 3 to 10
The range of g / m ² is appropriate. If the coating amount is less than 3 g / m ² , the sharpness (image resolution) of the image is insufficient,
If it exceeds 10 g / m ² , the ink absorbency and the ink drying property tend to be reduced. The dot shape adjusting agent-containing layer has an effect of forming the dot shape to be more perfect circle and further preventing the ink from bleeding.

In the recording material of the present invention, a writing layer which can be written by a pen plotter is provided as a layer (B) on the transparent substrate surface opposite to the ink receiving layer. The writing layer is not particularly limited as long as it can be written with a pen plotter, and is preferably matted with a binder and a roughening agent from the viewpoint of preventing curling. Examples of the binder include a thermoplastic resin, a thermosetting resin, a photocurable resin, and the like.Specifically, a resin used for the ink receiving layer, an acrylic resin, a urethane resin, a polyester resin, and a vinyl chloride resin are used. Each resin is mentioned. Further, as a roughening agent, for example, silica, zirconia, clay, kaolin,
Alumina, titania, zeolite, calcium carbonate, barium sulfate, magnesium hydroxide, calcium phosphate,
Examples thereof include inorganic powders such as glass, and synthetic resin powders such as acrylic resin, urethane resin, vinyl chloride resin, benzoguanamine resin, and benzoguanamine / melamine / formaldehyde condensate. The average particle diameter of the roughening agent is selected in the range of 0.1 to 20 μm, preferably 2 to 10 μm. Further, it is preferable to select the type and amount of the roughening agent so that the writing layer has transparency.

The thickness of the writing layer is advantageously in the range of 1 to 10 μm, preferably 3 to 7 μm, from the viewpoint that curl prevention and good writing can be obtained. Further, the writing layer may contain a conventionally used additive such as a surfactant, a lubricant, a stabilizer, and a colorant.

This writing layer is prepared by dissolving or dispersing the binder, the surface roughening agent and other additives in an appropriate solvent to prepare a coating solution, and then forming a coating liquid opposite to the ink receiving layer of the transparent substrate. It can be formed by coating and drying on the side surface according to a conventional method. At this time, in order to improve the adhesion between the base material and the writing layer, an appropriate undercoat layer may be provided on the base material, and the writing layer may be formed thereon, if desired.

In the present invention, a dot shape adjusting agent-containing layer can be provided on the writing layer thus provided, if desired. This dot shape adjusting agent-containing layer is as described in the above-described dot shape adjusting agent-containing layer provided on the ink receiving layer as desired.

FIG. 1 is an enlarged sectional view showing the structure of an example of a recording material. An undercoating layer 2, an ink receiving layer 3 recordable by ink jet, and dot shape adjustment are provided on the surface of a transparent substrate 1. Agent-containing layers 4 are sequentially laminated, and further, a mat layer 5 is provided on the surface of the transparent substrate 1 opposite to the ink receiving layer. The recording material of the present invention is provided with a writing layer that can be written by a pen plotter, instead of the mat layer 5.

In the recording material of the present invention having such a configuration, after printing is performed on the ink receiving layer by the ink jet method, if there is a correction portion, the ink receiving layer in that portion is removed by a chemical or physical method. Then, by rewriting on the writing layer corresponding to this portion with a pen plotter, correction and retouching can be easily performed. In addition, after forming an image by an ink jet method on the ink receiving layer of the recording material, necessary information is recorded by a pen plotter on the writing layer, so that color-coding work such as development drawings and design drawings can be easily performed. It can be carried out.

The recorded matter of the present invention is characterized in that (A)
A pattern formed by ink-jet on the layer and a pattern formed by a pen plotter on the layer (B) are respectively supported, and the pattern supported on the layer (B) from the layer (A) side However, each of the patterns carried on the layer (A) from the layer (B) side has a structure that can be seen through.
