As one type of image forming method capable of maximizing visual effects, including recording of a color image, a method of recording characters and labels having metal gloss has been developed in various applications.

Among them, a method using a paper having metallic luster such as a metal foil typified by aluminum foil is typical. However, when an image is printed on a metal foil itself by a thermal printer, the fixability of the dye is insufficient and an image can not be formed. To solve this problem, a high gloss paper as disclosed in the following documents has been developed.

Japanese Laid-Open Patent Publication No. 11-327442 discloses a metallic glossy recording paper comprising an adhesive resin layer, a metal foil layer, and a recording layer sequentially laminated on one side of a base film, Japanese Patent Application Laid-Open No. 2001-270234 Discloses a recording paper on which a recording layer containing a pearl pigment is formed on a support on which a matte metal surface is formed.

In these documents, a recording paper having the same effect as that recorded directly on a metal foil has been proposed. However, when a metal foil is used as a recording paper, a metal foil is placed on the entire surface of the printed material, It is hard to swallow.

Japanese Unexamined Patent Application Publication No. 2003-266956 discloses a thermal transfer sheet in which a resin releasing layer and a metal foil layer are laminated in order on one surface of a base film. A color image and a protective layer are formed on the body in advance, And the resin peeling layer and the metal foil layer of the thermal transfer sheet are transferred to form a metallic image.

In the above document, a thermal transfer sheet showing a noticeable effect by transferring a metallic image onto a transferred body on which a color image is formed is proposed. However, in the case of selecting a metal pigment to be applied to the metal foil layer and selecting a dye to be added to the resin release layer The color representation of the metallic image formed on the printed material is limited.

Japanese Unexamined Patent Application Publication No. 4-144790 discloses a method of forming a metal luster film by continuously forming an intermediate layer which is divided into a colored region and a colorless region on one side of a base film and laminating a metal thin film and a hot- And Japanese Unexamined Patent Application Publication No. 63-297090 discloses that a metal vapor deposition layer, a heat-fusible adhesive layer or a thermally-transferable coloring layer is formed in order on one surface of a base film through an intermediate layer Thermal transfer recording material.

In these documents, a thermal transfer recording material capable of forming a metallic image of a desired color tone on a transfer subject has been proposed. However, the thermal transfer recording material suggested in Japanese Patent Application Laid-Open No. 4-144790 is a dye And the thermal transfer recording material proposed in Japanese Patent Application Laid-Open No. 63-297090 is capable of expressing various colors of a metallic image. In production, however, an intermediate layer of a transparent color is formed in the adhesive layer There is still a problem in that it is difficult to correspond the thermally transferable coloring layer and the heat-fusible adhesive layer by separating the metal deposition layer after deposition of the vapor deposition layer. In addition, in order to form a metallic image of high quality, it is necessary to match the surface characteristics of the transferred body, the printing method, the printing conditions, and the like.

Hereinafter, preferred embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention.

FIG. 1 is a structural view of a recording material according to a first embodiment of the present invention, and FIG. 2 is a structural view of an ink ribbon according to a first embodiment of the present invention.

1, the printing method for forming a metallic image according to the first embodiment of the present invention and the recording medium used in the printing method include a redistribution film 1, an ink ribbon 2 and a metal foil ribbon 3 The specific configuration is as follows.

<Re-transfer film>

The redistribution film 1 according to the first preferred embodiment of the present invention comprises a first base film 11 and a dye receiving layer 12 formed on one surface of the first base film 11. [

The first base film 11 included in the redistribution film 1 serves to support the dye receiving layer 12 formed on one surface of the first base film 11, Mechanical stability and smoothness enough to withstand the heat applied in the step of forming the dye receiving layer 12, the step of transferring the metal foil layer 32, or the step of transferring the dye receiving layer 12 to the recording material.

The first base film 11 is preferably made of at least one selected from the group consisting of polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyamide, polyethylene and polypropylene, more preferably polyethylene terephthalate .

Here, the thickness of the first base film is preferably 5 to 20 탆. When the thickness of the first base film 11 is less than 5 탆, the step of forming an image on the dye receiving layer 12, the step of transferring the metal foil layer 32, or the step of transferring the dye receiving layer 12 to a recording material Wrinkles may occur in the redistribution transfer film 1 during transfer, whereas when the thickness exceeds 20 탆, heat transfer is not performed well, and when transferring the dye-receptive layer 12 to the transfer target body, The temperature of the heat generating device such as a head must be maintained at a high level.

The dye receiving layer 12 receives the dye transferred from the sublimable dye layer 22 and the metal foil transferred from the metal foil layer 32 to be finally transferred to the dye receiving layer 12, And adheres the metal foil to the surface of the recording material.

Here, the binder resin constituting the dye-receptive layer 12 is preferably a mixture of at least one selected from the group consisting of vinyl chloride-vinyl acetate copolymer, polyester, polyurethane, urea resin and polyamide.

In the step of forming an image composed of a sublimable dye by superimposing the sublimable dye layer 22 applied to one surface of the second base film 21 described later on the dye receiving layer 12 of the re-transfer film 11, In order to prevent fusion of the sublimable dye layer 22 and the dye receiving layer 12 of the re-transfer film 1, the dye receiving layer 12 may further include a releasing agent, 12, a separate release layer made of a releasing agent may be formed.

Here, the releasing agent is preferably a silicone type releasing agent, and the silicone type releasing agent may be an amino-modified silicone oil or an epoxy-modified silicone oil alone or in combination.

The dye-receptive layer 12 of the present invention may further include an additive such as an ultraviolet absorber or an antioxidant to improve the light resistance of the formed image.

The redistribution film 1 of the present invention may further comprise a first base film 11 and a second base film 11 in addition to the dye receiving layer 12 formed on one side of the first base film 11, Receiving layer 12 and / or a back layer formed on the opposite side of the first base film 11, as shown in FIG.

Here, the protective layer is transferred to the recording material together with the dye-receptive layer 12 to be positioned at the outermost portion of the final printed material, thereby protecting the final printed material. The backside layer serves to prevent the transfer of the dye-receptive layer 12 to the backside even when the re-transfer film 1 is exposed to a high temperature for a long period of time in a roll state, and the backside layer includes a binder resin and a release agent .

Here, in the case where the back surface layer is thick, heat transfer is impeded in the step of transferring the dye-receptive layer 12 of the redistribution film 1 to the recording material, so that the heating apparatus such as a heating roll or a thermal printing head is heated It is advantageous to make the thickness of the back layer as thin as possible.

The dye-receptive layer 12 may be obtained by applying a coating solution prepared by dissolving the binder resin and additives in an appropriate solvent to the first base film 11 and then drying the coating. The coating solution may be applied by a gravure coating method, A known coating method such as a micro gravure coating method or a bar coating method may be used.

Here, the thickness of the dye-receptive layer 12 is preferably 0.2 to 1.0 占 퐉 based on the dry state. If the thickness is less than 0.2 m, the dye transferred from the sublimable dye layer 22 can not be sufficiently accommodated. On the other hand, if the thickness exceeds 1.0 m, There is a problem that it is not adhered well to the surface of the recording material.

<Ink ribbon>

The ink ribbon 2 according to the first preferred embodiment of the present invention is used for printing images of various colors on the dye receiving layer 12 of the re-transferred film 1, And a sublimation dye layer 22 formed on one surface of the second base film 21.

Here, the ink ribbon 2 uses the principle of a sublimation type thermal transfer system, which is a type of thermal transfer recording system. In the sublimation type thermal transfer system, a thermal transfer ink ribbon Is also referred to as a dye diffusion type in which only the dye is transferred from the dye layer coated on one side of the substrate to the dye receiving layer to form an image.

The sublimation type thermal transfer method as described above has an advantage that the amount of dye transferred in proportion to the applied thermal energy can be adjusted, and thus it is easy to express a continuous change in color density in a transferred image. Therefore, the sublimation type thermal transfer method is widely used in fields of graphic design such as CAD and CAM, digital photo output, or an image which is electrically expressed from a color video camera to a color printer, because it can obtain very high quality images . In recent years, it has also been used in the production of identification cards and the like.

The principle of the sublimation thermal transfer recording system is that color images reproduced by an electrical signal are separated by color filters to separate into three images of red, green and blue, The branch images are transferred to the thermal elements of the thermal printer in the form of electrical signals.

On the other hand, when the thermal element of the thermal transfer printer applies heat energy to the opposite side of the sublimation dye layer to which the sublimation dye of the sublimation type thermal transfer ribbon is applied according to an electrical signal, the sublimation dye is transferred And an image is obtained.

For example, as shown in FIG. 2, the sublimation type thermal transfer ribbon has sublimation dyes of yellow, magenta, and cyan coated on one side of the second base film and the second base film, And the image is obtained by a combination of three dyes.

In the sublimation type thermal transfer recording system, since the image is formed with the dye having high light transmittance, it is possible to form a color by superimposing the dye. In this case, light is transmitted to the metal foil layer through the image layer, Is excellent in reproducibility.

In the present invention, the second base film 21 of the ink ribbon 2 serves to support the sublimable dye layer 22 formed on the second base film 21, Mechanical stability and smoothness enough to withstand the heat applied in the step of transferring the image onto the recording medium.

The second base film 21 is preferably made of at least one selected from the group consisting of polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyamide, polyethylene and polypropylene, more preferably polyethylene terephthalate .

On the other hand, since the second base film 21 generates high heat on the surface contacting the thermal head in the transfer step of the sublimable dye layer 22, the second base film 21 is prevented from being deformed into heat In order to improve the releasability between the thermal head and the second base film, a heat resistant layer may be formed on the opposite side of the second base film 22 on which the sublimable dye layer 22 is formed.

Receiving layer 12 of the redistribution film 1 in a state of being overlapped with the dye-receptive layer 12 applied to one side of the redistribution film 1 and transferring the dye to the dye- Type dye layer 22 is formed by applying ink in which a sublimable dye having a predetermined hue and a binder resin are mixed on one surface of the second base film 21 so as to be distinguished from each other in color.

Here, the sublimable dye may be selected from known dyes. Examples thereof include a methine type such as diarylmethane type, triarylmethane type, thiazole type, merocyanine and pyrazolone methine, indoaniline, acetophenone azomethine, pyrazoloazomethine, imidazoline, Aziridine series, benzeneazo series, pyridone azo series represented by azomethine series, xyanthene series, oxazine series, dicyanostyrene and tricyanostyrene, typified by azoamines and pyridone azomethines, Azo group, spiropyran group, indolinopyrapyran group, fluororan group, thiophene group, thiophene group, isothiazole group, pyrrole azo group, phthaloazo group, imidazole group, thiadiazole group, , Rhodamine lactam, naphthoquinone, and anthraquinone.

The binder resin is not particularly limited, and a known resin can be selected and used. Examples thereof include cellulose resins such as ethyl cellulose, cellulose acetate propionate, cellulose acetate butyrate, methyl cellulose, cellulose acetate and cellulose acetate butyrate, polyvinyl alcohol, polyvinyl acetate, polyvinyl butyral, polyvinyl acetal, poly Vinyl-based resins such as acrylamide, polyester-based resins, and phenoxy resins. Among these, polyvinyl acetal resin or polyvinyl butyral resin which is excellent in heat resistance and dye transferability is preferably used.

The sublimation dye layer 22 may further include additives such as an antioxidant, an ultraviolet absorber, a dye crystallization inhibitor, and a silicone release agent, depending on the intended use, in addition to the sublimable dye and the binder resin.

On the other hand, the sublimable dye layer 22 can be obtained by applying a coating solution prepared by dissolving the sublimable dye, binder resin and additives in an appropriate solvent to the second base film 21 and then drying the same. The coating solution may be a known coating method such as a gravure coating method, a micro gravure coating method or a bar coating method.
