Definitions
- the present invention relates to a method of forming a film near the surface of a recording material, such as an electrophotographic method, a thermal transfer method, an ink jet method using a hot melt ink, and a printing method.
- a recording material that is recorded by an image recording method that forms an image in the form of an image removes the image forming substance from the recording material that is no longer needed, and reproduces the recording material in a reusable state Related to the playback device.
- the method and apparatus for reproducing a recording material according to the present invention are applicable to various fields for removing foreign matter on the surface of a member, such as an electronic blackboard capable of automatically erasing an image. It can be applied.
- Japanese Patent Application Laid-Open No. 110157/77 discloses an image forming material on an image forming support.
- Japanese Patent Application Laid-Open No. 1-2972974 discloses that an image forming support is made of a material such as plastic, metal, paper having poor liquid permeability, or rubber or sock. Using the formed one, the image formed on the support is heated with a hot-melt release member interposed, and the image is released from the support. The method of disclosure is disclosed. However, this method requires the use of special paper whose surface has been released.
- the applicant of the present application has disclosed in Japanese Patent Application No. 5-202557 that at least a part is composed of a paper layer mainly composed of cellulose fiber.
- the recording material is impregnated with a liquid containing water, and the adhesion between the paper layer and the ink is weakened.
- the applicant of the present invention has proposed in Japanese Patent Application No. 5-96661 / 19 an apparatus configuration for realizing the reproduction method proposed in Japanese Patent Application No. 5-205257. .
- the recording material was not necessarily made of cellulose fiber as a main component, but at least near the surface where the image was formed. If the recording material has a layer that expands with a liquid containing water, the method according to Japanese Patent Application No. 5-205225 is effective. As a result, the present applicant has already proposed a recording medium, a reproducing method and a reproducing apparatus relating to the technology.
- FIG. 1 shows an example of an apparatus configuration for implementing the conventional method of the present applicant. Guide plate from paper feed tray 1 to paper feed roller 2
- the recording material conveyed from the conveyance port 4 is impregnated with the image removal accelerating liquid 7.
- the recording material, which has been coated and impregnated with the image removal accelerating liquid 7 and is in contact with the peeling member roller 5, is heated and pressed by the heating roller 8, and then is separated from the peeling member by the separating claw 9.
- the recording material is separated from the recording material.
- the separated image forming substance on the peeling member is cleaned from the surface of the peeling member roller 5 at the cleaning portion 1F, and is again returned to the peeling member roller.
- the image removal accelerating liquid is applied to the surface of 5.
- the recording material separated by the separation claw 9 is guided to the drying belt 1B by the conveyance port — line 1A, and dried.
- the dried recording material is conveyed.
- the sheet is ejected to the ejection tray 1C by the mouth line 1A.
- the discharged recording material is a recyclable recording material from which the image forming substance on its surface has been removed.
- the concentration (humidity) of the liquid components around the regenerating device rises abnormally, or the liquid components (water) condense in the regenerating device and cause electrical circuit trouble.
- the application state of the image removal accelerating liquid is not uniform.
- the recording medium may be curled or wavy deformed, resulting in defective conveyance of the recording medium in the reproducing apparatus. And reliable playback was not always possible.
- An object of the present invention is to solve the above-described problems and disadvantages of the conventional technology. That is, one of the objects of the present invention is to use an electronic photography method, a thermal transfer method, an ink jet method using hot melt in, a printing method, and the like. A film-like image is formed on the surface of the recording material It is an object of the present invention to provide a method and an apparatus for efficiently reproducing a recording material recorded by the used image recording method without background contamination.
- Another object of the present invention is to provide a method for reproducing a recording material according to Japanese Patent Application No. 5-202557, which was proposed by the present applicant, and Japanese Patent Application No. Hei.

By returning the recording material, the re-recording characteristics of the reproduced recording material, which is accumulated in the recording material and is reproduced, This may make it difficult to dry the recording material after removing the image.
- the application of the image removal accelerating liquid to the recording material is preferably performed in a plurality of steps.
- the application of the image removal accelerating liquid to the recording medium in multiple stages may be divided into any number of stages according to the purpose, but usually the operation becomes complicated and the apparatus becomes complicated. However, since there is no significant difference in the effects described below even if it is further divided, it is most preferable to perform it in two stages.
- the first application of the image removal accelerating liquid allows M
- the surface of the recording material and the image-forming substance is easily wetted by the image removal accelerating liquid, and the image removal accelerating liquid uniformly penetrates into the relatively shallow part of the recording material.
- a good amount of image forming substances can be removed by applying a small amount.
- Ordinary paper is a non-uniform recording material in which cellulose fibers are entangled, so if the image removal accelerating liquid is applied in a single application, it may cause unevenness in wettability.
- the image removal accelerating liquid may permeate non-uniformly in the depth direction of the paper and deeply into the paper. It is the swelling of the recording material in the vicinity of the portion where the image forming material and the recording material come into contact with each other, which contributes to the decrease in the adhesive strength between the image forming material and the recording material.
- the amount of the image removal accelerating liquid to be applied is reduced by increasing the wettability of the image removal accelerating liquid to the recording material and the image forming substance by using the image removing accelerating liquid applied first. Therefore, if this effect can be sufficiently obtained with the first image removal accelerating solution, the surface tension of the second image removal accelerating solution is relatively high and the wettability is low. However, a sufficient penetration rate can be obtained. Therefore, the concentration of the surfactant in the image removal accelerating solution provided in the subsequent step can be reduced. Reducing the concentration of the surfactant in the image removal accelerating liquid, which is applied in a later process, was repeated because unnecessary surfactant was not applied to the recording material.
- the image removal accelerating liquid By applying the image removal accelerating liquid a plurality of times so that the surfactant concentration of the liquid becomes lower as the post-process is applied, the image is removed. It has been shown that good image-forming substance removal characteristics can be obtained even when the amount of the accelerating liquid applied is reduced. It is also effective to apply the image removal accelerating liquid to the same recording material three or more times while using the removal accelerating liquid and gradually changing it for each coating process. However, the present inventor has generally determined that a solution containing a high concentration of a surfactant and a solution containing a low concentration of a surfactant or containing no surfactant are usually used. It has been found that by using a combination of two liquids, it is sufficiently possible to remove the image-forming substances. Takano It is preferable to use only two kinds of liquids, ie, a liquid and a low-concentration water-soluble liquid, in that the liquid applying device becomes simple and the reproducing operation of the recording material becomes simple.
- the surfactant-containing concentration of the image-removal-enhancing liquid applied to the same recording material in a plurality of times will be applied in a later step.
- the surfactant is preferably contained at a high concentration of 5 to 100% by weight, and the interface in the high concentration liquid is preferably used.
- the concentration of the activator is 5% by weight or less, the effect of sufficiently sufficiently removing the image forming substance cannot be obtained even when a small amount of the image removal accelerating liquid is applied in the present invention. No.
- the particularly preferred concentration of the surfactant in the high-concentration liquid is 5 to 50% by weight.
- a low-concentration water-soluble liquid contains a surfactant at a concentration of 5% by weight or less or does not contain a surfactant, for example, a water-soluble polymer. It is preferable to use an aqueous solution containing only an antiseptic or fungicide, or a liquid containing only water. Low concentration aqueous solution When the concentration of the surfactant in the body is 5% by weight or more, there are some conditions under which the image forming substance can be peeled off, but the characteristics of the reproduced recording material change, and the writability deteriorates.
- the image quality at the time of re-copying deteriorates, and problems such as the occurrence of wobble at the time of re-copying and the reduction of the number of reproducible times occur. Since the image forming substance can be sufficiently removed sufficiently, and the quality of the reproduced recording material is good, the recording and reproducing can be repeatedly performed and used.
- the concentration range of particularly preferred surfactant as a water-soluble liquid is 1% by weight or less o
- the amount of high-concentration liquid is less than 16 cm 2 (0.4 A lg per A4) and the amount of low-concentration water-soluble liquid or water applied is 16 // g Z cm 2 ( A4: 0.01)
- the image forming substance cannot be sufficiently removed.
- the amount of the high-concentration liquid applied is 6 mg / cm 2 (A4 size lg) or more, although the peeling of the image forming substance is good, the characteristics of the reproduced recording material are changed.
- the image is formed again on the recording material reproduced by a copy or the like, the image quality is deteriorated. Inconveniences such as a decrease in the number of times that can be prone to occur.
- the high concentration liquid is used.
- the phenomenon that occurs when a liquid is applied to the surface of the recording material that holds the image forming substance (image holding surface) will be briefly described with reference to FIG.
- surfactant molecules are shown in Figure 2.
- the image forming substance 203 is composed of a hydrophilic group 201 and a hydrophobic group (lipophilic group) 202. Therefore, when the concentration of the surfactant in the image removal promoting solution 20 is low, the image removal promoting solution 20 is used especially when the image removal promoting solution 20 is a solution mainly composed of water.
- the liquid in one application of the liquid, as shown in FIG. 3 (a), in the portion where the image forming material 203 does not exist, the inside of the recording material 10 is deepened. The liquid permeates to the surface of the image-forming substance 203, and the phenomenon that no liquid is present on the interface between the recording material 10 and the image-forming substance 203 occurs.
- the image removal accelerating liquid 20 is applied by a roller, the amount of the image removal accelerating liquid 20 adhering to the recording material 10 varies depending on the permeation speed.
- the background portion has a higher penetration rate than the image portion, and therefore does not contribute to a decrease in the adhesive strength between the image forming substance 203 and the recording material 10.
- a small amount of high-concentration liquid is applied to the image holding surface, as shown in Fig.
- the hydrophobic group of the surfactant adsorbs to the image forming substance,
- the liquid is evenly wetted by the recording material 10 and the image forming substance 203. It is presumed that the high-concentration liquid has a relatively high viscosity and relatively poor fluidity, which also contributes to the uniform application to the recording material 10. .
- the high-concentration liquid though slightly, has passed through the gap between the image forming substance 203 and reached the vicinity of the interface between the image forming substance 203 and the recording material 10. It is possible that It has been confirmed by microscopic observation and the like that even in the evening image (image with a large area), it has a structure with many holes inside.
- the image-forming substance 203 is also in advance. Since the high-concentration liquid is present, the low-concentration water-soluble liquid is not repelled, and is applied almost uniformly to the surface of the recording material 10 and the image forming substance 203. As described above, the factor contributing to the decrease in the adhesive strength between the recording material 10 and the image forming material 203 is penetrating into the vicinity of the interface between the recording material 10 and the image forming material 203. Water, but the liquid is impregnated into the entire recording material 10 by applying the liquid by the method according to the above action. Good peeling can be achieved even with a small amount of liquid.
- the method using two types of image removal accelerating liquids, a high-concentration liquid and a low-concentration water-soluble liquid is compared with the conventional method of applying only one image removal accelerating liquid.
- a large amount of the surfactant in the applied image removal accelerating liquid is distributed near the surface of the recording material.
- the type of surfactant used in the image removal accelerating liquid once the image forming substance is adhered and transferred to the release member by being pressed against the release member, it is necessary to perform the following steps.
- the effect of preventing the phenomenon (reattachment) of the image forming substance transferred to the peeling member side being transferred to the recording material again is exerted, and the effect is also reduced by the above-described image forming substance. It is presumed that this is one of the reasons for the effect of improving the removal characteristics.
- a liquid such as paper is permeable to the bulk (the liquid can penetrate from the front surface to the back surface or from the back surface to the surface).
- a recording material When using a recording material, apply a high-concentration liquid to the image holding surface of the recording material, and then apply a low-concentration water-soluble liquid from the opposite surface (non-image holding surface). It has been found that the effective peeling can be performed by applying the heat treatment.
- the amount of the image forming substance attached is large, and the image forming substance is completely in the form of a film, and it is difficult for the image removal accelerating liquid to permeate through the image forming substance.
- the high-concentration liquid contains a surfactant in a high concentration of 5 to 100% by weight.
- concentration of the surfactant in the high-concentration liquid is 5% by weight or less, it is possible to sufficiently remove the image-forming substance by applying a small amount of the image-removal promoting liquid. Not available. It is possible to remove good image-forming substances, obtain proper physical properties by applying liquid to the recording material, and form images using the same recording material. The number of repetitions of regeneration due to removal of the image-forming substance can be increased many times. Is 5 to 50% by weight.
- the low-concentration water-soluble liquid it is preferable to use a highly permeable water-soluble liquid containing 0.05 to 2% by weight of a surfactant in a concentration. No. If the concentration of the surfactant in the low-concentration water-soluble liquid is set to 0.05% by weight or less, it becomes difficult to remove a good image-forming substance, and the concentration of the surfactant in the low-concentration water-soluble liquid becomes low. When the content is more than 2% by weight, the exfoliation of the image forming substance is good, but the characteristics of the reproduced recording material are changed, the writability is reduced, and the image at the time of recopying is reduced.
- the particularly preferred concentration range of the surfactant as a low-concentration aqueous solution is 0.2 to 1% by weight.
- the appropriate amount of the high-concentration liquid and the low-concentration water-soluble liquid to be applied in this method is 16 g / cm2 to l. 6 mg Z cm ”(A 4 and a half!! 0.11 to g per liter).
- the concentration of low-concentration aqueous solution is 16 // g Z cm 2
- At least two kinds of image removal accelerating liquids of a high concentration liquid and a low concentration water-soluble liquid are used, and the low concentration liquid is applied from the back surface of the recording material.
- the addition of a wetting agent to the formulation of a high-concentration liquid is effective in improving the removal characteristics of the image-forming substance and in reducing the required amount of the image-removal promoting liquid.
- the wetting agent means a compound having excellent compatibility with water and having a lower vapor pressure than water.
- a compound include ethylene glycol, diethyl alcohol, triethylene glycol, and tereethylene glycol.
- One- and two-way teleports, one- and two-way teleports, one-way and one-way teleports Multivalent alcohol ethers such as ethyl ether, propylene glycol monoether ether, etc., N-methyl alcohol 2-Heterocyclic compounds such as pyrrolidone, 13, -dimethyl imidazolidinone, ⁇ -force program, etc Amines, such as MIN, JET-NO-REANO, MIN-TRI-ETHANOL, AMI, etc., are mentioned. Further, the above-mentioned wetting agent can be used as one kind or as a mixture of two or more kinds.
- the recording material and the peeling member are pressed against each other in a state in which an image removal accelerating liquid is applied to the recording material to weaken the adhesive force between the recording material and the image forming substance.
- the adhesive force with the peeling member is given while the image forming substance is heated as described above, and It is preferable that the recording material and the peeling member are separated in a state where the image forming material is heated.
- the reproduction of the recording material using the method of applying the image removal accelerating liquid for applying the low-concentration water-soluble liquid is performed.
- the recording material and the peeling member are pressed against each other to bond and transfer the image forming substance to the recording material, and the image forming substance is peeled off from the recording material.
- the temperature of the image holding surface side of the recording material is lower than the temperature of the non-image holding surface side. It was found that by heating the recording material in such a way that the recording material became dark, good peeling characteristics could be obtained. This is because, by setting the temperature on the non-image holding surface side of the recording material to be high, the temperature of the image removal accelerating liquid existing near the non-image holding surface side of the recording material is reduced. This is based on the effect that water moves to the lower recording surface side due to evaporation, thereby increasing the moisture density on the recording surface side. It is estimated to be .
