[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, in the image formation, a step of developing with a wet developer containing a colorant after forming a pattern of ions on a recording medium by a recording method of controlling an ion flow, The developed image is formed by transferring the developed image onto a secondary transfer member such as cloth, paper, film, or leather by thermal transfer. With the image recording method that controls the ion flow, in addition to the gradation control being possible for each recording dot, there is no worry of running cost increase due to large consumption of ink film as in the thermal sublimation recording method, so full-color images can be displayed. It is a recording method that can provide high image quality and low cost.

In the recording method of controlling the ion current, the ion current is controlled by forming a charge pattern on the recording medium by controlling the electric field of the ions generated by the discharge. Gradation control for each dot becomes possible by controlling the voltage applied between the electrode plates or the pulse width control that controls the time of the voltage pulse applied between the electrode plates. It is possible to form a gradation image that could not be obtained by the method of forming an image by electric means. Therefore, the recorded dots are modulated dot by dot by dot printing, and the gradation density control and gradation reproduction capability that simultaneously control the volume gradation and area gradation of each dot enable delicate reproduction of the edge part, etc. And increase the effective resolution. As a result, the size of the dot can be changed in a short time of several microseconds, so that halftone dot gravure tone expression is possible. In addition to these, the fact that the dots keep a sharp shape without the influence of the history even at the edge portion of the line drawing is more advantageous compared to the thermal sublimation recording method in which tailing or the like easily occurs due to the influence of the thermal history. Is a point. Further, it is possible to form an electrostatic pattern without using a mask pattern by using an electrostatic plotter or the like, but in this case, a binary image is generally used and gradation expression is limited. I will end up. Further, when the gradation of the gradation is expressed by performing image processing other than binary without restricting the printing speed, the gradation or resolution is also limited because the gradation is expressed.

The peeling layer is the outermost layer on the secondary transfer that is peeled off from the base sheet when it is transferred to the secondary transfer after the image is formed on it, so it has flexibility and abrasion resistance. It is preferable that the resin is composed of a synthetic resin having heat resistance and heat resistance in the transfer step, and water-soluble polyvinyl alcohol, gelatin, epoxy resin, melamine resin, phenol resin, fluorine resin, silicone.

When the thickness of the release layer is 0.1 g / m ² or less in dry weight, the function as the release layer cannot be exerted, and uneven coating is likely to occur during coating. If the thickness of the release layer exceeds 10 g / m ² on a dry weight basis, the original surface characteristics of the secondary transfer material will be impaired.

Further, the conductive layer 23 to the surface to form a release layer of the substrate sheet formed on the opposite side is available what is commonly known in the electrostatic recording paper or the like, 10 ¹¹
It is preferable that the surface resistance is Ω / □ or less. 10 ¹¹
If it is larger than Ω / □, the ion pattern is disturbed due to peeling discharge, or fogging occurs, which causes a problem in image quality. As such a conductive layer, one having ion conductivity or electron conductivity is used, and examples thereof include a conductive resin containing quaternary ammonium and a film-like material containing conductive fine particles of metal or metal oxide. . It may be mixed with a polymer electrolyte or a polymer binder and applied on a substrate, or a thin film may be formed and laminated on the substrate, or may be formed by vacuum deposition, sputtering or the like.

The transfer recording medium shown in FIG. 4B has a matting layer 24 provided on the peeling layer 22. The matting layer is formed in order to form irregularities on the surface layer of the transfer recording medium so that the movement of the transfer recording medium is not hindered even if the transfer recording medium is sucked into the slit during development. The matting layer can be formed by applying a dispersion of fine particles of an inorganic or organic substance using a synthetic resin as a binder.

The matted release layer is a combination of the release layer and the matting layer shown in FIG. 4 (B). The material used for forming the release layer is mixed with fine particles used for the matting layer to form a matte release layer. It can be formed in the same manner as the chemical conversion layer. Further, the matting layer may be formed as an intermediate layer of the laminate instead of being provided on the surface layer, and it can be formed in the same manner as when it is formed as the surface layer. Particles for the chemical conversion layer may be added, or a plate having irregularities on the surface may be pressed to form the substrate, and a substrate sheet having irregularities on the surface may be used. The preferred range for the matte layer or the unevenness provided on the surface varies depending on the developing device and the like, but the surface smoothness is about 10 to 1000 seconds in terms of Beckman smoothness, and the surface roughness Rz (10-point average roughness).
JIS-B06010) having a thickness of 100 nm to 10 μm is preferable.

Further, the surface of the transfer recording material is shown in FIG.
As shown in (D), an adhesive layer 28 for adhering to the secondary transfer member may be formed in advance. For the adhesive layer used for such a purpose, a resin or the like that does not exhibit adhesive or adhesive properties during image forming work can be used. For example, synthetic rubber such as styrene-butadiene rubber, acrylic resin, methacrylic resin, polyvinyl ether resin, vinyl acetate resin, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin, styrene resin, polyester resin, polyamide resin, A thermoplastic resin capable of satisfactorily heat-sealing an image to a secondary transfer member which does not exhibit tackiness after coating selected from polyvinyl butyral resin and the like is dissolved with an organic solvent or the like, and coated with an appropriate viscosity.

As shown in (F), it is possible to prevent the transfer product from peeling from the surroundings by forming the adhesion strengthening layer 29 having a high adhesive strength around the adhesive layer 28 and transferring the same to the secondary transfer member. As the adhesion-strengthening layer, the same material as the material for the adhesion layer, particularly one having excellent adhesion strength can be used.

The transfer recording medium shown in FIGS. 4A to 4F uses a synthetic resin sheet such as polyethylene terephthalate as the base sheet, and has a conductive layer on one side of the base sheet and the other side. Is provided with an image forming surface. Then, the transfer recording material is attached to the ion image forming apparatus to form a conductive connection between the conductive layer and the apparatus side. Further, in order to maintain the mechanical strength of the transfer recording medium and facilitate handling, the base sheet has a relatively large thickness. Therefore, when the image based on the ion image is formed, the base sheet of the insulator acts as a dielectric, so that a high voltage may be charged between the conductive layer and the surface layer to cause discharge. .

Such a discharge problem can be prevented by disposing the conductive layer on the same side of the base sheet as the side on which the ion image is formed. This can also be prevented by using as the conductive layer a base sheet having conductivity. Further, it is also possible to use a conductive paper or a paper known as an electrostatic recording paper in which a dielectric layer is formed on the conductive paper. Such a conductive base sheet can be produced by a method similar to the method of forming the conductive layer on the base sheet. In addition, the conductive paper includes inorganic salts such as sodium chloride, cationic polyelectrolytes such as polyvinylbenzyltrimethylammonium chloride, anionic polyelectrolytes, surfactants, zinc oxide, or zinc oxide subjected to electroconductivity treatment. Paper having a surface resistance of 10 ⁵ to 10 ¹¹ Ω impregnated or coated with a metal oxide semiconductor such as the above can be used.

The conductive connection between the conductive layer and the ion image forming apparatus can be performed by providing an end surface of the conductive layer or a portion of the conductive layer that does not affect image formation with a portion on which no other layer is formed.

As shown in FIG. 4H, a matting layer 24 may be provided on the release layer, and the arrangement of the conductive layer and the release layer in FIG. A conductive layer may be provided and a matting layer may be formed thereon. FIG.
As shown in (I), a matted release layer 25 in which a release layer and a matting layer are integrated may be provided. The matt layer and the matt release layer can be formed in the same manner as shown in FIG. 4 (B) or FIG. 4 (C). Further, a transfer recording medium having an adhesive layer 28 on the surface thereof as shown in FIG. 4 (J) can be manufactured in the same manner as in FIG. 4 (D).

Further, as shown in FIG. 4 (K), an adhesive layer is provided only on the periphery, or as shown in FIG. 4 (L),
An adhesion reinforcing layer 29 may be provided around the periphery. In the case where the release layer is arranged on the side of the base sheet, when the image is formed and then transferred to the secondary transfer member, the conductive layer is transferred to the secondary transfer member together with the release layer. Those having high transparency are preferable.

Further, as shown in FIGS. 4 (G) to 4 (L),
When the release layer and the conductive layer are provided on one surface of the base sheet, a release layer may be provided prior to the formation of the release layer, and any layer such as the release layer, the release layer, or the adhesive layer may be matted. It may also serve as a matting layer, and any layer can be used as a matting layer. In addition, the conductive layer may be any layer other than the surface layer on which an image is formed, or may be a release layer, a release layer, a matting layer, or two or more layers may also serve as the conductive layer. Can be

In FIG. 5, in the step (A), in the ion printer, the conductive layer 23 is provided on one surface of the base sheet, and the release layer 22 is provided on the other surface. The image 26 is formed. In the step (B), the ion image is developed with a developing solution for image formation to give a colored image 2
7 is formed. The step (A) and the step (B) are C,
A color image can be formed by repeatedly forming and developing an ion image of three colors or four colors of M, Y or C, M, Y, Bk.

Next, in step (C), an adhesive layer 28 is formed on the colored image. The adhesive layer is the secondary transfer member 30.

The thickness of the adhesive layer to 1 dry weight was 30 g / m ^2, preferably from 3 to 15 g / m ^2. The thickness of the adhesive layer is 1g / m ²
Below, sufficient adhesion cannot be obtained. If it exceeds 30 g / m ² , the original surface characteristics of the secondary transfer material are impaired. Next, in step (D1), the secondary transfer member 30 is laminated on the adhesive layer 28, and in the heat roll step (E), the recording transfer member and the secondary transfer member are heat-fused and integrated with each other by a heat roll. .

Further, without passing through the step (C) of forming the adhesive layer, in the step (D2), the material on which the adhesive layer 28 is formed in advance is laminated on the surface to be transferred on the secondary transfer member 30, and the heat roll is applied. In step (E), the recording transfer member and the secondary transfer member are heat-sealed by a heat roll. The method of heat fusion can be appropriately set according to the characteristics of the recording transfer member and the secondary transfer member to be used, but the temperature is 100 to 2
In the range of 00 ° C, preferably 120 to 180 ° C, the linear pressure is 3 to 30 kg / cm, preferably 5 to 15 kg / c.
m, the feed rate of the heat roll is 20 m / min or less, preferably 5 to 15 m / min. Transfer temperature is 100 ℃
If it is lower, the adhesiveness between the adhesive layer and the secondary transfer material or between the adhesive layer and the image forming surface of the transferred image recording material cannot be sufficiently obtained, and uniform transfer cannot be performed. If the temperature exceeds 200 ° C, the base sheet or the secondary transfer material may be deformed or deteriorated.

Next, in the peeling step (F), the recording transfer member and the secondary transfer member are peeled off in the peeling layer to obtain a transfer material 31 on which an image is transferred. In the heat fusion in the above heat roll step, when the adhesive strength to the secondary transfer member is not sufficient, the transferred material after peeling is further heated under heat by a heat press using a heating plate. It may be pressed to increase the adhesive strength. Further, the transfer recording material of the present invention can obtain an excellent secondary transfer material by being used in a method of forming an image by an ion flow, but an image forming method by an electrostatic printer using a multi-stylus head is used. It can also be used for an image forming method using an electrophotographic method.
