Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inkjet recording medium having an ink receiving layer, an inkjet recording medium, and a method for producing an inkjet recording medium. These recording media and recording materials are posters and
Used for stickers, labels, displays, cut letters, etc.

[0002]

2. Description of the Related Art Ink jet recording is a system in which minute droplets of ink are ejected and adhered to a recording medium such as paper by various operating principles to record images and characters.

Since this ink jet recording system is characterized by high-speed printing, low-noise printing, easy multicolor printing, and no need for development / fixing, it is used as an output device for characters, figures, color images, etc. It is rapidly spreading in applications. Further, an image formed by the multicolor inkjet recording system can obtain a recorded image comparable to that of the multicolor printing by the plate making system or the printing by the color photographic system. In addition, since it can be manufactured at a lower cost than the case where a photographic technique is used in applications where the number of copies to be manufactured is small, it is widely applied to the field of full-color image recording.

By the way, conventionally, when a pasting member such as a poster, a sticker, a label, a display, a cut letter, etc. is pasted on an adherend such as a bulletin board or a window glass for display, the pasting member or the pasting member is pasted. A strong adhesive is applied and attached to the place to be attached, or it is attached using an attaching member to which an adhesive adhesive is applied in advance.

Since the conventional pasting members were not considered for peeling after use, when the pasting members were peeled off after use, traces of the adhesive remained on the pasting surface of the adherend, or peeling did not occur. Since it is difficult, the adherend may be damaged. In addition, it was almost impossible to reuse the adhesive member after peeling.

In order to solve the above problems, a foam resin layer (adsorption layer) is provided on the base material of the pasting member, and the base material is directly printed or adhered to the surface of the base material on which the foam resin layer is not provided. Methods such as pasting printed vinyl chloride sheets through the layers are used. By these methods, even when the adhesive member is attached to an adherend such as a bulletin board or window glass, it can be easily peeled off from the adherend after use, and the adhered member can be repeatedly used.

The above-mentioned products have already been provided.
For example, Retekker (registered trademark, manufactured by Eiho Co., Ltd.) forms a foamed resin layer (adsorption layer) on the base material by applying a special acrylic synthetic resin to the nonwoven fabric of the base material and foaming it. Has been done. In addition, PAPIRAL (registered trademark, manufactured by Dainippon Ink and Chemicals, Inc.) is a base material P
A foamed resin layer (adsorption layer) is formed on the ET film.

On the other hand, with the diversification of needs, recording media which can be printed by the ink jet recording system are increasingly used for label applications such as price display labels, bar code labels and advertisement labels. There is. The barcode label utilizes the high sharpness characteristic of the inkjet recording system. In addition, since the label for advertisement has excellent sharpness and color, it is possible to obtain a good image, and thus the advertising effect is great. Labels are used in many fields because they adhere well to various adherends and are easy to apply.
Label applications combining the feature of the ink jet recording system that a good image can be easily obtained are expanding.

Conventionally, in the method of manufacturing an ink jet recording medium for achieving such a label specification, an adhesive layer is directly formed on the back surface of the ink jet recording medium obtained by the existing technique, and the adhesive layer is released. The inkjet recording medium for labels has been produced by laminating a flexible sheet and then punching the inkjet recording medium into a predetermined label shape.

However, in the ink-jet recording medium for labels produced by the above method, the adhesive layer is formed directly on the back surface of the ink-jet recording medium. The sharpness and chromaticity of the image deteriorated with the enlargement, and the image reproducibility was poor. If the high sharpness and image reproducibility, which are the characteristics of the inkjet recording system, deteriorate, the value as an inkjet recording medium for a label is low.

In order to solve the problem of "ink blurring" caused by such an adhesive layer, a back coat (barrier layer) is provided on the back surface of the ink jet recording medium, or an adhesive sheet is used as a means for forming the adhesive layer. There are known methods, such as ripping.

[0012]

However, as a first problem, the above conventional products have the following drawbacks.

(A) In the method of directly printing on the surface of the base material on which the foamed resin layer (adsorption layer) is not provided, a poster
The production cost is high because printing cannot be performed unless a block copy such as stickers, labels, POPs, and cut letters is created, and the unit price cannot be reduced unless a large number of designs are produced.

(B) In the method of sticking a printing sheet (printed vinyl chloride sheet, art paper, etc.) on the surface of the base material on which the foamed resin layer (adsorption layer) is not provided, with an adhesive layer, Warpage occurs in the laminated body including the base material and the printing sheet due to the difference in humidity and humidity. Furthermore, the printed sheet may peel off from the base material.

(C) A print sheet is attached to the surface of the base material on which the foamed resin layer (adsorption layer) is not provided, with an adhesive layer, and then the surface on which the foamed resin layer is provided has substantially the same size as the print sheet. In addition to the same drawbacks as in (b), in the method of sticking the printing sheet of No. 1 with the adsorption margin left and sticking it to a transparent adherend such as a show window or window glass and displaying from both inside and outside the store, Since the thickness of the printing sheet is as thick as 0.3 to 0.5 mm, there is a drawback that the attaching member is easily peeled off from the adherend (see FIG. 15).

Therefore, a first object of the present invention is (i) an image can be formed without a plate and the manufacturing cost is low, (ii) warping or peeling of a sticking member does not easily occur, and (iii) a transparent adherend. Provided is an inkjet recording medium composed of a sticking member capable of being repeatedly stuck and peeled, which has any or all of these characteristics such that it is difficult to peel from a sticker even after sticking and performing double-sided display. It is to be. Another object of the present invention is to provide an inkjet recording material in which an image is formed on these inkjet recording media.

As a second problem, the conventional method for manufacturing an ink jet recording medium for labels has the following problems.

When a conventional ink jet recording medium is processed by slitting or punching in order to process it into a predetermined shape and size, the adhesive substance of the adhesive layer adheres to the blade edge and the sharpness of the blade remarkably deteriorates. The inkjet recording medium could not be cut or punched in time.

Further, it is necessary to remove the sticky substance from the cutting edge and to replace the cutting blade or the punching blade itself each time, which remarkably reduces the productivity of the inkjet recording medium for labels. In particular, since the punching process is performed in a continuous operation, if the timing of removing the sticky substance or exchanging the punching blade is incorrect, a defective product may be produced and the production yield of the inkjet recording medium for labels may be reduced.

Therefore, a second object of the present invention is to provide a method of manufacturing an ink jet recording medium in which an adhesive substance is not attached to a cutting blade, a punching blade or the like.

[0021]

Further, as the image-formed product (7) of the ink jet system, a mirror image of a desired image is formed on the ink receiving layer formed on one surface of the transparent resin layer, and this mirror image is further formed. The surface of the formed ink receiving layer side may be bonded to the support through an adhesive layer. For example, if a mirror image is formed as shown in FIG. 4 (A), it can be seen from the surface as an image of FIG. 4 (B). As a result, the image is provided with gloss or the like to form a good image, and the image is protected by the transparent resin, so that a clean image can be maintained for a long time.

Here is an example applied to.

As shown in FIG. 15, the conventional sticking member capable of double-sided display is repeatedly stuck.
Printed vinyl chloride sheets (20a, 29b) were attached to both sides of the peelable support (4). Such a sticking member has a drawback that it is easily peeled off from the glass window (15) which is the stuck object because the thickness of the printed vinyl chloride sheet is 0.3 to 0.5 mm. It was It has been found that the main cause thereof is the floating (21) of the adsorption portion generated around the printed vinyl chloride sheet (20b).

Therefore, in the present invention, an ink receiving layer is formed on a specific portion of the surface of the support (4) to be attached / peeled off,
An image was formed on this ink receiving layer. It can be attached to the wall surface of a glass window or the like due to the adsorptivity of the area where the ink receiving layer is not formed on the surface to be attached / peeled.

EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to these examples.

Example 1 A retainer (registered trademark, manufactured by Eiho Co., Ltd.) in which a foamed resin layer (3) was formed on a nonwoven fabric which was a base material A (2a),
A release paper was laminated as a release product (5). After this was cut to A4 size, an ink receiving layer (1) was formed on the base material A as shown in FIG. The foamed resin layer is formed by applying acrylic special synthetic resin to a non-woven fabric and foaming the same.

Alumina hydrate was used as a pigment for the coating solution for forming the ink receiving layer (1) (specific surface area of alumina hydrate: 200.2 m ² / g, pore volume: 0.
71 ml / g). The coating liquid was prepared as follows. The above alumina hydrate was dispersed in ion-exchanged water, and then polyvinyl alcohol (gohsenol NH-18,
An aqueous solution of ion-exchanged water in which Nippon Synthetic Chemical Industry Co., Ltd. was dissolved was added. At this time, the ratio of the solid content weight of alumina hydrate / the solid content weight of polyvinyl alcohol (pigment / binder = P / B) was set to 15/1. After the addition, the mixture was thoroughly mixed and stirred for dispersion treatment. The obtained coating liquid was dropped on the base material A (2a) and then uniformly coated with a roll bar. Then set in the oven for 10
Drying was performed at 0 ° C. for 10 minutes. The coating amount of the ink receiving layer (1) (100 ° C., absolute dry weight for 10 minutes)
Was set within the range of 21 to 50 g / m ² . The coating amount is suitably 4 to 100 g / m ² , and preferably 21 to 50 g / m ² .

As described above, the ink receiving layer (1) is formed on the base material A (2a) of the retainer (support (4)) which can be repeatedly attached and peeled by the foamed resin layer (3).
Was obtained, and the releasable product (5) was laminated on the foamed resin layer (3) to obtain the inkjet recording medium of the present invention.

An image was formed on the ink jet recording medium of this example by using PixelJet (registered trademark, manufactured by Canon Inc.) with a photograph of "Autumn mountain" as an input image. As a result, it was possible to obtain an inkjet recording material on which an oil-painting-like image having a very good feeling was formed due to the texture of the nonwoven fabric.

The OD value (optical density) was measured by a color checker (manufactured by Macbeth). As a result, Y (yellow): 1.24, M (magenta): 1.46, C (cyan): 1.41, B (black): 1.61.

For the evaluation of water resistance, an ink jet recording material was dipped in tap water for 3 seconds and then naturally dried in a suspended state, and a drop of tap water was printed with a dropper. After dropping onto black letters (title or signature, etc.), a "drying water resistance against water" test was conducted in which it was naturally dried. As a result, the "water resistance of the dripping water" was very good and no bleeding occurred. With respect to "water resistance of immersion", only a slight amount of ink flow occurred in magenta, but the others had almost no effect.

The release material (5) was removed from the ink jet recording material of the present invention, and the surface on the foamed resin layer (3) side was attached to the door. The ink-jet recording material of the present invention can be repeatedly attached and removed on a smooth surface, and the attachment position can be freely changed according to the mood of the day. Moreover, since it does not require a frame, it can be safely attached to a door that is often opened and closed.

Example 2 As a release material (5) on a papillar (registered trademark, manufactured by Dainippon Ink and Chemicals, Inc.) in which a foamed resin layer (3) was formed on a PET film as a base material A (2a). Of the release sheets were laminated. After this was cut to A4 size, an ink receiving layer (1) was formed on the base material A as shown in FIG. A coating solution similar to that of Example 1 was used.
The ink receiving layer (1) was formed on the base material A by coating and drying in the same manner as in (1). However, the coating amount (100 ° C
The absolute dry weight for 10 minutes) was set within the range of 40 to 120 g / m ² . The coating amount is 21 to 200 g / m.
² is suitable, and preferably 40 to 120 g / m ² .

As described above, the ink receiving layer (1) is formed on the base material A (2a) of the papilla (support (4)) that can be repeatedly attached and peeled by the foamed resin layer (3). The inkjet recording medium of the present invention was obtained in which the release material (5) was laminated on the foamed resin layer (3).

Using a pixel jet, the four seasons of Japan were photographed on the ink jet recording medium of this example.
An image was formed by using one photo as an input image. As a result, since the PET film had good smoothness, a photographic image could be obtained for each.

The OD value was measured by a color checker (manufactured by Macbeth Co.), and Y, M, C and B were 1.21, 1.47, 1.60 and 1.64.

Regarding the water resistance, "water resistance of dripping water" did not cause much bleeding, and the ink receiving layer was only slightly deformed. In "water resistance of immersion", Y, M, C, and B generated some ink flow, but had almost no effect.

The ink jet recording material of this example was applied to a calendar (see FIG. 5). Twelve sheets of inkjet recording material (9) were attached to the printing surface of each month of the calendar, which is the printed material (8) coated with the resin or the cast coat, to give a calendar illustration. After one month, we decided to remove the recording material (9), store it in a file case, and use it again in the next year.
By storing it in a file case, you can use it as a calendar illustration any number of times.

Example 3 An inkjet recording material having the structure shown in FIG. 2 was produced.
As base material B (2b), A4 size DX diamond white <90K> with very good air permeability of 56.0
(Registered trademark, Mitsubishi Paper Mills Ltd.) was used.

A coating solution similar to that in Example 1 was applied and dried in the same manner as in Example 1 and then ferro-applied to form an ink receiving layer (1) on the base material B (2b). did.
However, coating amount (100 ° C, absolute dry weight for 10 minutes)
Was set within the range of 10 to 40 g / m ² . The coating amount is suitably 4 to 55 g / m ² , and preferably 1
It is 0 to 40 g / m ² .

Next, an adhesive layer (6) is interposed between the surface of the base material B (2b) on which the ink receiving layer is not provided and the base material A (2a) of the retainer on which the release material is laminated. Both of these members were joined and then trimmed to obtain an inkjet recording medium of the present invention.

Using the pixel jet, an image was formed on the ink jet recording medium of this example by using a photograph of "autumn leaves" as an input image. As a result, it was possible to obtain an inkjet recording material on which a very pleasant photographic image was formed due to the texture of the paper.

As a result of measuring the OD value by a color checker, Y, M, C and B were 1.62 and 1.6, respectively.
It was 5, 1.51, 1.67.

As a result of the water resistance test, almost no bleeding was observed in the printed portion in the "water resistance of the dripping water". In the "water resistance of immersion", ink flow occurred in Y, M, C, and B, but it was not so remarkable that color mixing occurred.

Example 4 An inkjet recording material having the structure shown in FIG. 2 was produced.
A metal film coating film was used as the base material B (2b).

The same coating liquid as in Example 1 was applied and dried in the same manner as in Example 1 to form an ink receiving layer (1) on the base material B (2b). However, coating amount (100 ° C
