Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproducible image support on which an image is formed by an electrophotographic system or a thermal transfer system.

[0002]

2. Description of the Related Art In recent years, global environmental problems have surfaced, and effective use of limited resources has been recognized. As part of measures to reduce the use of resources, once used plastics and the like are reprocessed without being discarded. Reuse has become a social demand. It is also required that the OHP film made of a plastic film used as an image recording support be reused. However,
OHP film is used for confidential documents, especially in companies, so there is also a problem such as data leakage.
Incinerated as disposable. This film is provided with an image receiving layer on the surface in order to strongly fix the image forming material and improve the color development. Even if the image on the film on which the image is formed is erased, the image receiving layer is disturbed, and the disturbed portion causes light scattering and lowers the light transmittance. Not available. Further, the image can be removed by dissolving the image receiving layer using an organic solvent. However, a film from which the image receiving layer has disappeared cannot be used as an OHP film. Even if an image could be fixed using an unprocessed film, it would take considerable effort to cleanly remove all the images.

In general, when a plastic film is used as an image recording medium, the surface of the recording medium is easily damaged because it is formed of an organic substance. The damaged part will appear as an image. In particular, since a transparent polyethylene terephthalate (PET) film or a laminated film usually has a smoothness of 300 seconds or more as measured by a Beck's smoothness meter, the surface is immediately damaged even by slight rubbing or the like. However, since it appears as a stain on the projection screen, there is a problem in its handling.

When an OHP film is reproduced using an organic solvent, a large amount of the organic solvent is required.
In addition, since the reproducing apparatus itself is large, complicated, and expensive, it is impossible for an individual to cope with it, and a certain number of companies must be requested. At the same time, if the separation, collection, transportation, accumulation and operation of the equipment are not performed efficiently, a large amount of energy will be consumed and the global warming phenomenon accompanying the increase in the amount of CO ₂ will be further promoted. It could be.

On the other hand, there are cases where it is required to easily transfer an image produced on an image support to another medium on the spot, and in such a case, an image transfer body having transferability is used. However, even if you try to copy a pattern that can be copied in sophisticated colors like a recent color copier on a medium other than paper or film as it is, such as a cloth product, at present it will not pass smoothly through the copier. Have difficulty.

As a method for solving the above-mentioned problems relating to the image support, there is known a method of erasing and reproducing an image on a recording support which has been used once.
Japanese Patent No. 55195 discloses an erasable printed material in which a plastic, metal, paper or ceramic having no liquid permeability is used as an image support, and a silicone sealant, that is, a release agent made of silicone rubber is applied to the surface of the image support. Have been. In this method, an image formed with a hot-melt ink on a support is heated and pressed with a hot-melt exfoliating body interposed therebetween, and after cooling, the image is peeled off from the support and erased. Since the agent is easily transferred, the agent adheres to a contact portion such as a paper passing / conveying roller in the apparatus, and causes paper jams, dust and paper stains due to adhesion of dust or toner floating in the apparatus. Therefore, if it is provided as a uniform thin layer in order to reduce the migration of the silicone sealant, unevenness and unevenness occur, making it impossible to uniformly and stably exist on the film, which hinders the projected image. Occur. Also, because of the portability as described above,
When the regenerating process is repeated, the advantage of the release agent is reduced, and there is a problem that the recording preservability is poor if the release agent is weakly bonded to the image support.

[0007] The following are examples of the image support provided with release properties. First, Japanese Patent Application Laid-Open No. Hei 5-216376 discloses a toner for forming an image by using a recording paper coated with a release agent on a recording surface at the time of erasing an image and pressing the recording paper against a medium made of a material which is easily offset. Methods for transfer and removal have been proposed. The release agent used in this method is a liquid, such as silicone oil, fluorinated oil, or other aliphatic oil, and is of such a degree that the recording paper exhibits transparency in order to obtain a sufficient toner release effect. The recording paper must be applied at a high density, resulting in a low-quality recording paper that impairs the image of plain paper. When a plastic film is used in place of the recording paper, the release agent oil does not penetrate, so it becomes sticky or has poor fixability. There is a problem that lacks. Further, since the release agent oil used has a migration property, the above-mentioned Japanese Patent Application Laid-Open No.
It also has the same problem as that of JP-A-55195.

Japanese Patent Application Laid-Open No. Hei 6-219068 discloses a heat transfer recording paper obtained by applying or impregnating a heat-transferable recording material with a heat-modified material, for example, a fluorine-containing acrylate material, which reduces the adhesion to the image forming material by heating. A reproducible recording paper is disclosed. However, the recording paper used is a thermal transfer paper, which has higher smoothness and lower fixability than plain paper, and those materials have poor adhesion to the thermal transfer recording paper base material. Since the paper is easily transferred, the paper feed roller and the recording paper are likely to slide in the copying machine, and a printing failure may occur due to a recording paper jam or misalignment. As a solution to this problem, it has been proposed to provide a region on the thermal transfer recording paper that is not coated or impregnated with a heat-denaturing material. However, this method complicates the manufacturing process and makes the recording paper easier. There is a problem that the production cost increases because the production cannot be performed and labor is required.

[0009]

In order to improve the prior art as described above, a recording layer containing a curable silicon compound chemically bonded to the surface of a substrate is first provided on a substrate made of a plastic film. (Japanese Patent Application No. 8-187214). However, depending on the type of the image forming material, the image support may have reduced image fixing properties. Therefore, the recording layer was provided by mixing different types of modified silicone oils.
When used as an OHP film, when there is no compatibility between the oils to be mixed, there is a problem that the light transmittance of the transparent film is reduced.

[0010] Accordingly, the present invention has been made in view of the above-mentioned circumstances, and has an object to improve the prior art.

That is, an object of the present invention is to provide an image support which can be easily reproduced after being used for recording an image. More specifically, the present invention aims at effective recycling of resources to facilitate reproduction. An image support that provides an OHP film with good light transmittance, can be easily transferred from these image supports to other media, and can be reproduced without damaging the support surface while transferring the image forming material. Is to provide the body. Still another object of the present invention is to provide an excellent image support in which a material having a releasability does not migrate and can smoothly pass through an image forming apparatus.

[0012]

The present inventors have conducted intensive studies on the above-described image support, and as a result, a thin film having good releasability and an image forming material are provided on the surface of the image support by directly reacting the same. This makes it possible to form an image in which the image forming material is fixed without damaging the surface of the image support, and to peel off and transfer the image. The present inventors have found that an image support that can be easily reproduced even when printed on a sheet is obtained, and the present invention has been completed.

That is, the image support of the present invention is a reproducible one and comprises a cured product of a curable silicone compound and a modified silicone oil having two or more functional groups in a molecule on a substrate. In which a recording layer is provided.
The substrate in the image support of the present invention is preferably a transparent plastic film. The recording layer can fix the image forming material by heat and remove the fixed image forming material by heat.

The curable silicon compound is preferably at least one selected from an isocyanate silane compound, an alkoxysilane compound, a silane coupling agent and a silane compound having a SiH group. Also,
As the modified silicone oil having two or more kinds of functional groups in a molecule, a modified silicone oil having two or more kinds of functional groups selected from an amino group, an alkoxy group, an epoxy group, a polyether group and a carboxyl group is used.

The reproducible image support of the present invention is obtained by coating or impregnating a liquid composition containing a curable silicone compound and a modified silicone oil having two or more functional groups in a molecule on a substrate, It can be manufactured by drying and curing to form a recording layer.

In the image support of the present invention, a liquid composition containing a curable silicone compound and a modified silicone oil having two or more different functional groups in a molecule is coated on a substrate and dried. Then, a recording layer bonded to the surface of the base by a chemical reaction is formed, and the recording surface has a good releasability from the image forming material. The modified silicone oil having two kinds of functional groups in the molecule used in the present invention does not make the recording layer opaque when the substrate is transparent, and has a fixing property and a releasing property to the image forming material. However, it does not separate from the substrate. That is, there is no transferability to others. Therefore, although the formed recording layer has a small thickness, it not only facilitates peeling of the image forming material, but also does not impair its effect semipermanently.
Also, the scratch resistance of the surface is improved.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the image support of the present invention will be described in detail. In the present invention, as the substrate of the image support, any known plastic film conventionally used as an image recording medium can be used, and in particular, a plastic film having a light-transmitting property that can be used for OHP. It is preferred to use The use of the light-transmitting plastic film also has the advantage that the peeled state of the image during transfer can be confirmed from the back surface of the base. Examples of such a film include an acetate film, a cellulose triacetate film, a nylon film, a polyester film, a polycarbonate film, a polystyrene film, a polyphenylene sulfide film, a polypropylene film, a polyimide film, and cellophane. ,
In consideration of electrical, physical, chemical properties, processability, and the like, it is preferable to use a polyester film, and particularly preferable to use a biaxially stretched polyethylene terephthalate film. Also, paper and the like can be used.

The recording layer in the image support of the present invention comprises:
In order to facilitate the reproduction of the image support, a curable silicon compound which is bonded to a substrate such as the plastic film by a chemical reaction is used. As a result, in the present invention, the curable silicone compound of the recording layer does not migrate from the substrate to the image forming material, but does not separate, while having the releasability from the image forming material. In addition, even if the recording layer is a thin film, the image forming material can be easily peeled off to be reproducible, and its effectiveness is not semipermanently impaired. Further, the image support of the present invention,
Since the above-described treatment is performed, the scratch resistance of the surface is improved, and both the release property and the scratch resistance can be achieved.

In the present invention, a modified silicone oil having two or more functional groups in a molecule contained in a liquid composition for forming a recording layer (hereinafter, referred to as a “modified silicone oil having different functional groups”). Are modified silicone oils with amino and alkoxy groups, modified silicone oils with amino and polyether groups, modified silicone oils with epoxy and polyether groups, and modified silicone oils with carboxyl and polyether groups And silicone oil. In addition, other modified silicone oils having different functional groups can be sufficiently used as long as they have no problem of coloring or discoloration. Further, the viscosity of the modified silicone oil having different functional groups is determined in consideration of the combination with the curable silicone compound, but is determined to be 5 to 20,000 centistokes (cSt).
Are preferred. The addition ratio of the modified silicone oil having a different functional group to the curable silicone compound can be arbitrarily changed according to the purpose. However, the addition ratio is preferably such that the blending amount of the modified silicone oil having different functional groups is in the range of 10 to 200 parts by weight with respect to 100 parts by weight of the curable silicone compound. If the amount of the modified silicone oil having a different functional group is too small, it is difficult to remove the fixed image forming material, and if the amount is too large, the surface of the substrate becomes sticky.

When the recording layer contains a modified silicone oil having the above-mentioned different functional groups, the interaction between the modified silicone oil and the curable silicone compound improves the releasability of the image forming material of the film. Durability is improved. Although the detailed mechanism is unknown, the silicone oil chain is intricately entangled with the curable silicone compound, and as a result, the organic distribution of various organic groups present on the surface, in particular, the polar group and the microscopic distribution of ionic bonding are controlled. It is considered that an optimum surface structure for peeling the image forming material is formed.
In addition, these selected compounds are entangled between molecules, thereby further improving the durability.

The liquid composition for forming the recording layer on the substrate surface contains, in addition to the curable silicone compound and the modified silicone oil described above, other additives within a range that does not impair the effectiveness of the release property and the scratch resistance. It can be contained. For example, an aluminum compound, a titanium compound, a zirconium compound, and a fluorine compound can be contained,

It is also desirable to use a copolymer obtained by introducing a curing agent with a vinyl ether, specifically, ethyl vinyl ether, cyclohexyl vinyl ether, or the like. In addition, the formula: X-CF ₂ (OC ₂ F ₄ )

Examples include an alcohol-modified product represented by CF ₂ —CH ₂ [(OCH ₂ CH ₂ ) _n ] OH (n is an integer) and an ester-modified product represented by —COOR (R is an organic group). . Furthermore, as a conductive agent, in order to control the electrification due to static electricity generated when peeling the overlapping films,
You may mix metal oxides, such as stannic oxide and ITO, and anionic, cationic, and nonionic surfactant as a surfactant. The amounts of these additives can be appropriately set as long as the effectiveness of the releasability and the scratch resistance is not impaired, but are generally blended in a range of 50% by weight or less.

In the present invention, as a coating method or an impregnation method for forming a recording layer on a substrate surface such as a plastic film, a blade coating method, a wire bar coating method, a spray coating method, a dip coating method, a bead coating method, A commonly used method such as an air knife coating method, a curtain coating method, a rod bar coating method, and a roll coating method is employed.

The applied liquid composition is then dried and cured to form a recording layer. Drying by air drying may be used to form the cured product, but heat drying is preferred because releasability from the image forming material increases. It is presumed that the reason for this is that components reacting with the surface of the substrate such as plastic are arranged or oriented, but it is not clear. For this heating, a commonly used method such as putting into an oven, passing through an oven, or contacting with a heating roller is employed.
