2. Description of the Related Art In recent years, a thermal transfer recording system using a thermal transfer ribbon such as a melt thermal transfer ribbon or a sublimation thermal transfer ribbon and a thermal head has become widespread, and this system is suitable for printing a small number of copies. Furthermore, multi-color recording is performed using an ink ribbon of any color, or three colors of YMC of yellow (Y), magenta (M), and cyan (C),
YMCB with black (Bk) added as necessary
Full color recording can also be performed by subtractive color mixing using k4 colors.

When printing with a metallic luster in these thermal transfer recording systems, a thermal transfer ribbon in which an ink layer contains a metallic luster pigment has been used. It is also possible to transfer a pigment having a metallic luster of an arbitrary color by including a pigment or dye of an arbitrary color in the ink layer having the metallic luster pigment.

[0004]

However, in order to obtain a multi-color or full-color recorded product having metallic luster by using these conventional metallic luster thermal transfer ribbons, for example, each dye of YMC is contained in the ink layer. YMC
Even if recording is performed using the transfer ribbon of, since the ink layer containing the metallic luster pigment, which is printed later, overlaps the previously printed color, the underlying color is completely hidden. However, full color cannot be reproduced as it is, and a desired expected color cannot be expressed.

Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a metallic luster thermal transfer recording material suitable for recording a color image having metallic luster such as multi-color or full color, and a metallic luster due to the thermal luster It is an object of the present invention to provide a method for recording a color-expressable recorded matter, and a color-expressable recorded matter obtained as a result.

[0006]

In order to solve the above-mentioned problems and achieve the object, the metallic luster thermal transfer recording material, the recording method and the recorded material of the present invention are, as the recording method, a thermal transfer ribbon having metallic luster. First, a transfer section having a metallic gloss layer is formed, and then a recording layer of a desired color is formed on the transfer section by a printing method such as thermal transfer using a thermal transfer ribbon. A color record was obtained. Then, by appropriately selecting at least one color of three colors of YMC or four colors of YMCBk as a color to be printed, a full-color metallic (metallic luster) tone recorded matter is obtained.

The metallic luster thermal transfer recording material of the present invention, which can be used in this recording method, has at least a metallic luster layer formed by dispersing a metallic luster pigment in a resin on one surface of a substrate, An ink receiving layer is provided between the layer and the metallic luster layer.

BEST MODE FOR CARRYING OUT THE INVENTION The layers constituting the metallic luster thermal transfer recording material of the present invention will be sequentially described in detail below, and then the recording method and recorded matter of the present invention will be described in detail. FIG. 1 is a vertical sectional view of an embodiment of the metallic luster thermal transfer recording material of the present invention. In the metallic luster thermal transfer recording material 1 of the present invention shown in FIG. 1, a back surface layer 7 is formed on the back surface side of a base material 2, and on the front surface side of the base material 2,
The peeling layer 3, the ink receiving layer 4, the metallic luster layer 5, and the adhesive layer 6 are sequentially formed. The back surface layer 7, the peeling layer 3 and the adhesive layer 6 may be omitted depending on circumstances. Then, when this metallic luster thermal transfer recording material is thermally transferred, a transfer portion having a structure in which the ink receiving layer covers the metallic luster layer is obtained.

One of the features of the metallic luster thermal transfer recording material of the present invention is that the transferred transfer layer (transfer portion) has ink receptivity. For the purpose of merely forming a transfer layer having a metallic luster, the metallic luster thermal transfer ribbon is composed of a coating liquid in which a metal powder such as aminium, copper or copper alloy is dispersed in wax or resin. If the composition is applied on the film, the object can be sufficiently achieved. In order to obtain a full-color or multi-color recorded product having a metallic luster tone, it is possible to use the ribbon having the above structure. That is, full-color or multi-color printing is further performed on the transferred portion having the transferred metallic luster.

However, in the conventional transfer foil, it is not taken into consideration that the ink is further stacked on the transfer layer. Therefore, when full-color or multi-color recording is performed on the transfer portion obtained from the metallic glossy thermal transfer recording material having such a configuration, there is no particular problem when performing overprinting with the resin-type melt thermal transfer ink, When performing overprinting with melted thermal transfer ink containing wax as the main component, the wax component is difficult to be compatible with the resins forming the outermost layer of the transfer layer, resulting in insufficient transfer and insufficient sensitivity, Problems such as the wax flowing and uneven printing occur. Further, even when the sublimation heat transfer ink is used for overprinting, recording cannot be performed if the outermost layer of the transfer layer does not have dye acceptability, or the sublimation heat transfer ribbon and the transfer layer are thermally fused during printing. Problems such as storage will also occur.

Therefore, in the present invention, as shown in FIG. 1, as a metallic glossy thermal transfer recording material capable of obtaining a transfer portion whose outermost layer has ink receptivity, insufficient sensitivity or printing with the above-mentioned molten thermal transfer ink is carried out. The problems of unevenness and dye fixing property with sublimation heat transfer ink and releasability of recording material were solved. When the melt heat transfer ink is used, the ink acceptability with good compatibility with the melt heat transfer ink is obtained, and when the sublimation heat transfer ink is used, the dye acceptability with respect to the sublimation dye used in the sublimation heat transfer ink is excellent. It has ink receptivity. When transferring a metal film layer such as a metal deposition layer as a metallic gloss layer, it is possible to impart the above-mentioned ink receptivity by using an appropriate resin for the ink receiving layer which is the outermost layer of the transfer layer. I chose

By using the metallic luster thermal transfer recording material having the above-described structure, it becomes possible to perform extremely good melt thermal transfer or sublimation thermal transfer recording on the transfer printed portion, and full color or multicolor It is possible to obtain a recorded matter having a good metallic luster.

Further, the color ink used for an ordinary ink ribbon for mono-color printing has low transparency of ink, and if this is directly printed on the transfer portion of the metallic luster thermal transfer recording material, it is transparent or metallic luster. It is difficult to get a good feeling. Therefore, in the recording method of the present invention and the recorded matter obtained as a result thereof, in order to solve this point, the transparency of the recording layer formed by transferring the ink is specified.

Hereinafter, returning to FIG. 1, the material of each layer will be described in detail.

Next, the material of each layer will be described. First, as the base material 2 of the metallic luster color thermal transfer recording material 1 of the present invention,
The material is not particularly limited as long as it is a material that can withstand heating of the thermal head during thermal transfer recording and has desired heat conductivity, mechanical strength, etc., and known materials used for conventional thermal transfer ribbons and the like can be used. For example, there are plastic films such as polyester, polypropylene, polystyrene, cellophane, cellulose acetate, polycarbonate, polyvinyl chloride, polyvinylidene chloride, polyimide, etc., condenser paper, papers such as paraffin paper, non-woven fabrics and the like. It may be what you did.

The thickness of the substrate is appropriately adjusted in view of its mechanical strength and thermal conductivity, but it is usually preferably about 2 to 25 μm. Base material 2 as in one embodiment of FIG.
A heat-resistant back surface layer 7 for preventing thermal fusion with the thermal head may be provided on the back surface of the. In addition to the heat resistance, the back surface layer 7 may be provided with a sliding function for improving the sliding property.

For the purpose of heat resistance, a known thermosetting resin such as a melamine resin or a thermoplastic resin such as a silicone resin or a fluorine resin is used as the back layer. Used, and to obtain lubricity, a filler,
Additives such as lubricants and antistatic agents are added. The thickness of the back surface layer is sufficient as long as it can prevent fusion and smoothness, and is usually about 0.1 to 3 μm.

The peeling layer 3 is a layer forming the outermost surface of the recorded matter by transferring and transferring from the metallic luster thermal transfer recording material to the transferred material side in the thickness direction in whole or in part by cohesive failure during transfer recording. . In the case of partial transfer or full transfer, it is preferable that the cohesive force at the time of recording is low so that the print may be cut off. Alternatively, it may be a layer that does not transfer at all. In short, the peeling layer is a layer that allows the metallic luster thermal transfer recording material to peel off on the layer or on the surface adjacent to the layer, thereby allowing the substrate to be separated from other layers.

Examples of the peeling layer 3 include carnauba wax, paraffin wax, microcrystalline wax, ester wax, Fischer Tropsch wax, various low molecular weight polyethylene, wood wax, beeswax, whale wax, ivowa wax, wool wax, shellac wax, Various waxes such as candelilla wax, petrolactam, partially modified wax, fatty acid ester and fatty acid amide can be used.

As the release layer 3, a resin other than the above wax can be used as long as the release property from the substrate is appropriate, and the resin may be only the resin or a mixture of the wax and the resin. Examples of such a resin include rubber-based resins such as polyisoprene rubber, styrene-butadiene rubber, and butadiene acrylonitrile rubber, acrylic ester-based resins, polyvinyl ether-based resins, polyvinyl acetate-based resins, vinyl chloride-vinyl acetate copolymers. Body resin, polystyrene resin, polyester resin, polyamide resin, polychlorinated olefin resin, polycarbonate,
Examples thereof include polyvinyl butyral resin. further,
If necessary, a softening agent, a filler and the like can be added to the release layer.

The thickness of the release layer 3 is generally 0.1 in terms of coating amount.
The range is from 10 to 10 g / m ² . When it is less than 0.1 g / m ^2, it does not function as a peeling layer, and when it exceeds 10 g / m ² , the print quality is deteriorated and gradation recording is not particularly good, and the foil retention is deteriorated. It may result in being unusable. The material of the release layer generally has good compatibility with the molten thermal transfer ink, so that these inks do not interfere when the ink is transferred to the ink receiving layer, but in the case of the sublimation thermal transfer ink, In particular, the wax-based release layer may hinder the transfer of the sublimation dye to the ink receiving layer or may be fused during transfer. For this reason,
For the purpose of sublimation thermal transfer, the release layer should be selected in consideration of this point.

The ink receiving layer 4 serves as the outermost layer of the transfer portion formed by transfer with the metallic luster thermal transfer recording material, and forms a recording layer having a good ink fixing property by receiving ink on or inside itself. It is a layer that helps. Therefore, it is desirable that the material of the ink receiving layer is appropriately selected from materials compatible with the ink used.

When a melt heat transfer ink is used as the ink, a resin having a good compatibility with the wax used in the melt heat transfer ink is selected to give good ink transferability.
Good melt thermal transfer ink receptivity is obtained. Resins having good receptivity to the melt heat transfer ink include thermoplastic resins, and particularly, polyalkylene such as polyethylene and polypropylene, ethylene-vinyl acetate copolymer, polyvinyl acetate, ionomer resin, ethylene-ethyl acrylate copolymer. , Ethylene-acrylic resin such as acrylic acid copolymer, polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polyvinyl ether, polyvinyl acetal, polyvinyl butyral, polyvinyl alcohol, polyvinylpyrrolidone, polyester, polyutalene, polyamide, ethyl cellulose, It is effective to use one type or a combination of two or more types of fiber type polymers such as nitrocellose and cellulose acetate, and rubber type polymers such as chlorinated rubber and natural rubber.

On the other hand, when a sublimation heat transfer ink is used as the ink, a resin having good dyeability with respect to the sublimable dye used provides good sublimation heat transfer ink receptivity. Examples of such a resin include polyester, polyacrylic acid ester, polycarbonate, polyvinyl acetate, styrene-acrylic acid ester copolymer, vinyltoluene-acrylic acid ester copolymer, polyurethane, polyamide, urea resin, polycaprolactone. Polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polyacrylonitrile and the like are effective. Further, either one or both of an ultraviolet absorber and a light stabilizer may be added to these resins for the purpose of enhancing the weather resistance of the dye transferred and transferred. Also,
For the purpose of improving the releasability from the sublimation heat transfer sheet at the time of recording, a new outermost layer covering the outermost ink receiving layer after transfer is provided between the release layer on the substrate and the ink receiving layer (transfer A release layer may be formed. Alternatively, a release agent may be contained in the ink receiving layer. As the release agent, solid waxes such as polyethylene wax, amide wax and Teflon powder, fluorine-based and phosphoric acid ester-based surfactants, and silicone oil are preferable.
When the release layer is formed, it becomes the outermost layer after transfer, so the thickness is made as thin as about 0.1 to 1 μm so as not to hinder the transfer of the dye.

If a resin having good receptivity to the sublimation heat transfer ink and a resin having good receptivity to the melt heat transfer ink are used, a resin having good sublimation heat transfer ink receptivity and good melt heat transfer ink receptivity is obtained. It can also be used.

The thickness of the ink receiving layer is 0.1-2.
The coating is formed in the range of 0 g / m ² . If the amount is less than 0.1 g / m ² , a sufficient fixing effect of waxes of the melt heat transfer ink and dyes of the sublimation heat transfer ink cannot be obtained. On the other hand, 20g
If it exceeds / m ² , the printing sensitivity (transfer sensitivity) is significantly reduced.

The metallic luster layer 5 is formed of a layer in which a metallic luster pigment such as metal powder is dispersed in a resin. As the metallic luster pigment, aluminum powder, bronze powder, copper powder, tin powder,
A metal powder such as lead powder or zinc powder or a pigment having a metallic luster such as a pearl pigment is used. As the resin, a thermoplastic resin, for example, a conventionally known resin such as an ethylene resin, a styrene-butadiene copolymer, an acrylonitrile-butadiene copolymer, an acrylic resin or a polyester resin can be used. The thickness of the metallic luster layer is 0.1 to 20 g /
A range of m ² is preferred. If it is less than 0.1 g / m ² , sufficient glossy feeling cannot be obtained, and if it exceeds 20 g / m ² , the sensitivity is remarkably lowered.

An adhesive layer 6 can be further provided on the metallic luster layer. In this case, the adhesive layer 6 includes, as a wax component, waxes such as microcrystalline wax, carnauba wax, paraffin wax and the like, which are mentioned as the materials that can be used for the release layer, and thermoplastic resins such as eletin-vinyl acetate copolymer. A single type or a suitable mixture of these can be used. The thickness of the adhesive layer is 0.1 to 10 g / m
² If it is less than 0.1 g / m ² , sufficient adhesive force cannot be obtained and sensitivity is insufficient. If it exceeds 10 g / m ² , excessive energy is required to melt the adhesive layer, and
Foil breakage also decreases, which is not preferable. It should be noted that, for example, by adding the waxes described above to the resin component forming the metallic luster layer or using a resin having adhesiveness with the transfer target such as acrylic resin or ethylene resin, The layers can be omitted.

Further, a release layer, an ink receiving layer, and
To form a metallic luster layer, adhesive layer, or back layer,
As a coating liquid in which the constituent material of the layer is dissolved or dispersed in a solvent such as an organic solvent, it can be formed by conventionally known gravure coating, gravure reverse coating, roll coating, knife coating, and many other known coating means. Also,
When the layer is mainly composed of wax, coating means such as hot melt coating and hot lacquer coating can be used.

The metallic luster thermal transfer recording material of the present invention constructed as described above is used only by itself and is printed by a thermal head of a thermal transfer printer used for a conventionally known thermal transfer ribbon. It can also be used as a thermal transfer ribbon for recording, etc., but its feature is that the metallic gloss layer is transferred by this thermal transfer recording material and further ink (especially,
This is a case of obtaining a recorded matter in which a recording layer is formed by sublimation heat transfer ink or melt heat transfer ink. Then, by using a plurality of inks of different colors, a multi-colored printed matter having a metallic luster or a full-colored printed matter can be obtained. In addition,
The metallic luster thermal transfer recording material may be in the form of a sheet as well as a ribbon.

Next, the recording method of the present invention for obtaining a recorded matter having a metallic luster by using the above metallic luster thermal transfer recording material will be described. In the recording method of the present invention, first, the metallic glossy thermal transfer recording material is used to transfer the metallic glossy layer to form a transfer portion, and then a recording layer is formed on the transfer portion having the metallic glossy layer with ink. However, it is necessary that the recording layer has such a degree of transparency that it does not hide the underlying metallic gloss layer.
Regarding the surface relationship between the transfer portion and the recording layer, the recording layer may be formed on the entire surface or a part of the transfer portion, and if necessary, the recording layer may be formed on the surface other than the transfer portion.

As a method of forming a recording layer of ink on the transfer portion, since the transfer portion is ink-receptive, if the obtained recording layer has appropriate transparency, offset, gravure, silk screen, etc. Conventionally known various printing means may be used, but since the metallic luster thermal transfer recording material of the present invention takes into consideration sublimation thermal transfer ink and melt thermal transfer ink, sublimation transfer or melt thermal transfer by a known thermal transfer printer using a thermal head is performed. The thermal transfer printing method is good. If a printer is used, a different image can be easily formed for each recorded material as compared with the printing means.

The color of the recording layer is not particularly limited to a chromatic color, and may be any color such as black single color or two colors, and is not limited to full color expression. In any case, the advantages of the metallic luster layer and the ink receiving layer, which are one of the features of the recording method of the present invention using the metallic luster thermal transfer recording material, are fully exhibited. If a conventional metallic luster transfer material is used as a material to be printed with an ink to obtain a recorded matter having a metallic luster tone, it is usually difficult to expect favorable ink receptivity, but according to the present metallic luster thermal transfer recording material. There is an advantage that a desired material such as paper can be prepared as a material having a metallic luster and having ink-receptive property. However, the recording method of the present invention exerts an advantage that has not been obtained in the past in multi-color and full-color expression using a plurality of color inks.

In the ink layer of the conventional metallic luster thermal transfer material,
Process colors such as yellow, magenta, cyan, and black are prepared, and if the density gradation of each color can be expressed by the size of halftone dots, it has a metallic luster in the same way as a general printing method such as offset. It seems that the recorded material can be expressed in full color. However, in this case, when another color is laminated on the previously printed color, the lower color is blocked by the metal vapor deposition layer that is formed at the same time when the upper color is formed and becomes invisible. Does not occur, and ink full-color expression is not possible.

However, in the recording method of the present invention, since the metallic glossy layer is first transferred in a batch at a required place and then the inks of respective colors are arranged, the above-mentioned formation is performed first. It is possible to perform full-color expression using process colors and multi-color expression using arbitrary colors without blocking the formed color during the subsequent color formation. Therefore, the four process colors of yellow, magenta, and cyan, which are the three primary colors of subtractive color mixture, which are used in conventional thermal transfer recording materials, and black, if necessary, are used in the same manner as the full-color expression by conventionally known printing. By the method of
A full color expression of metallic luster is obtained.

Further, it is desirable that the recording layer of the color ink has such a transparency that the metallic luster layer formed thereunder does not impair the metallic luster. In this respect, the transparency of the recording layer, and in particular, when the recording layer is used to obtain a full-color recorded product of subtractive primary colors YMC or YMCBk, the transparency of each color may be set as follows. In the case of yellow, the transparency is 70% or more in the range of 550 to 780 nm, and in the case of magenta, the transparency is 3
70% or more in the range of 80 to 450 nm and 600 to 780 nm, and the transparency is 380 to 550 in the case of cyan.
It is preferably 70% or more in the range of nm.
If the transparency of each color is less than 70%, the recorded matter will be cloudy with impaired glossiness, and good subtractive color mixing will not be possible, resulting in a narrow color reproduction range. The transparency when the recording layer is black is 30% to 50% when it is particularly necessary to reproduce glossy black.
%) Is required, but in the case of aiming at full-color reproduction, sufficient reproduction can be obtained without a glossy feeling, so that even if the transparency is 0%, there is no problem. If the transparency is 0%, the lower metallic luster layer is invisible because it is invisible, and is unnecessary and may be omitted.

For the purpose of expressing a perfect natural color,
The above YMCBk ink is preferable, but it is not limited to these colors for the purpose of obtaining a color recorded matter having another color effect or the like.

The color recorded matter having the metallic luster of the present invention can be obtained as described above. The recorded material has a structure in which a recording layer made of ink, an ink receiving layer, a metallic gloss layer, and an adhesive layer are laminated on a transfer target such as paper from at least the front side in the recorded portion. Depending on the presence or absence of the release layer of the thermal transfer recording material or the release mode of the release layer, part or all of the release layer in the thickness direction is interposed between the ink receiving layer and the ink recording layer.
