Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an intermediate transfer recording medium having a transfer portion comprising at least a receiving layer provided on a base film so that a thermal transfer image is formed on the transfer portion. The present invention relates to a print obtained by retransferring the transfer portion to a transfer target.

[0002]

2. Description of the Related Art Conventionally, a thermal transfer method has been widely used as a simple printing method. The thermal transfer method is such that a thermal transfer sheet having a color material layer provided on one surface of a base material sheet and a thermal transfer image receiving sheet having an image receiving layer provided as necessary are superimposed, and the thermal transfer sheet is heated by a heating means such as a thermal head. Is heated imagewise to selectively transfer the colorant contained in the colorant layer to form an image on the thermal transfer image receiving sheet.

[0003] Thermal transfer methods are classified into a melt transfer method and a sublimation transfer method. The melt transfer method uses a thermal transfer sheet in which a hot-melt ink layer in which a coloring material such as a pigment is dispersed in a binder such as a hot-melt wax or a resin is supported on a base sheet such as a PET film, and a thermal head or the like is used. This is an image forming method in which energy is applied to the means in accordance with image information, and a color material is transferred together with a binder onto a thermal transfer image receiving sheet such as paper or a plastic sheet. An image formed by the fusion transfer method has high density and excellent sharpness, and is suitable for recording a binary image such as a character.

On the other hand, the sublimation transfer system mainly uses a thermal transfer sheet in which a dye layer in which a dye that transfers heat by sublimation is dissolved or dispersed in a resin binder is supported on a base sheet such as a PET film. This is an image forming method in which energy corresponding to image information is applied to a heating means, and only dye is transferred to a thermal transfer image receiving sheet provided with a dye receiving layer on a base sheet such as paper or plastic as required. In the sublimation transfer method, since the transfer amount of the dye can be controlled in accordance with the amount of energy applied, a gradation image in which the image density is controlled for each dot of the thermal head can be formed. Further, since the coloring material to be used is a dye, the formed image has transparency and excellent reproducibility of an intermediate color when dyes of different colors are superposed. Therefore, when thermal transfer sheets of different colors such as yellow, magenta, cyan, and black are used and each color dye is transferred onto the thermal transfer image receiving sheet in a superimposed manner, a high-quality photographic full-color image excellent in reproducibility of intermediate colors can be obtained. Formation is possible.

The specific application of the thermal transfer image-receiving sheet by such a thermal transfer method is wide-ranging. Typical examples are print proofs, image output, CAD /
Design and output of CAM, etc., various medical analysis equipment such as CT scan and endoscope camera, output use of measurement equipment and as an alternative to instant photography, as well as identification cards, ID cards, credit cards, other cards It can be used to output a face photo to a kind, a synthetic photo in an amusement facility such as an amusement park, a game center, a museum, an aquarium, and a use as a commemorative photo. With the diversification of applications as described above, the demand for forming a thermal transfer image on an arbitrary object has increased, and as one of the measures, as an intermediate transfer recording medium in which a receiving layer is provided on a base material in a releasable manner. By using a thermal transfer sheet having a dye layer or a heat-fusible ink layer on the receiving layer, a colorant such as a dye or a pigment is transferred to form an image, and then the intermediate transfer recording medium is heated to form a receiving layer. Has been proposed for transferring the image on a transfer target. (Japanese Unexamined Patent Publication No. 62-238791, etc.)

In addition, the use of the above-mentioned intermediate transfer recording medium allows the transfer of the receiving layer to the object to be transferred.
It is preferably used for a transferred body in which a color material is not easily transferred and a high-quality image cannot be directly formed, a transferred body which is easily fused to a color material layer during thermal transfer, and the like. For this reason, the intermediate transfer recording medium is preferably used for producing identification cards such as passports and prints such as credit cards and ID cards.

[0007]

However, when the receiving layer is transferred to the transfer-receiving member using the above-mentioned intermediate transfer recording medium, the transfer is performed in a simple shape such as a square or a round shape and a solid shape over the entire surface. When doing, it does not matter much, but when providing a hollow part in the transfer part, or when the shape of the outer edge is complicated, the edge of the receiving layer transferred to the transfer object is not sharp, There is a problem that the transferability of the receiving layer is unstable because a portion not to be transferred is transferred or a portion to be transferred is not transferred. In particular, when the above-mentioned portion of the receiving layer that should not be transferred is, for example, a column for entering an address or a name, or a sealing column of a writer or issuer, the receiving layer is transferred to that portion at all. In such a case, the written contents and the seal are unclear, which is a major problem that the contents cannot be read.

[0008] With respect to the above-mentioned instability of transferability of the receiving layer, the receiving layer is once transferred in a simple shape such as a square or a circle, and then a layer dedicated for writing or stamping is added thereto, and printing is performed. To be provided. However, in this case, there is a problem that it takes time and effort to add the dedicated layer, and the manufacturing cost becomes extremely high. Therefore, the present invention solves the above-mentioned problems, and forms a thermal transfer image on the transfer portion by using an intermediate transfer recording medium provided with a transfer portion comprising at least a receiving layer so as to be peelable on a base film. However, when the transfer portion is re-transferred to the transfer object, a portion that is not partially transferred to the transfer object can be formed accurately and stably, and the production cost does not increase to obtain a final print. The purpose is to provide prints.

[0009]

According to the present invention, in order to achieve the above object, an image is formed by using an intermediate transfer recording medium provided with a transfer portion comprising at least a receiving layer so as to be peelable on a base film. The printed material is characterized in that at least one surface of the printed material is provided with a portion where the transfer portion is not retransferred. This is a design part such as a sign panel, an IC chip, and a magnetic stripe of a printed matter, a logo pre-printed on an object to be transferred, and a design part such as a hologram in a transfer part of the intermediate transfer recording medium, and there is no transfer part. With the configuration (blank portion), the portion excluding the blank portion is retransferred to the transfer receiving body, and a print is obtained. Signed panels, IC chips,
In a portion such as a magnetic stripe, a decrease in performance in post-processing of the portion can be prevented. Further, in a design design portion such as a logo and a hologram, when the transfer portion is transferred, transparency is impaired (opacity is increased), and quality is deteriorated. The above-mentioned sign panel portion is a portion which is handwritten with a writing instrument such as a ball-point pen, numbered with stamp ink, or stamped with vermilion or stamp ink. Further, the printed matter of the present invention can be separated from an arbitrary position of the transfer part in a printed matter formed on an intermediate transfer recording medium provided with at least a transfer part comprising a receiving layer so as to be peelable on a base film. When the masking layer is transferred to the transfer member, and then the transfer portion of the intermediate transfer recording medium is re-transferred onto the transfer member, only the transferred portion of the mask layer is not transferred to the transfer member. In this method, a masking layer is thermally transferred to a transfer portion of an intermediate transfer recording medium by using a heat transfer sheet having a masking layer on a base film, and the transferred portion of the masking layer is used to transfer the transfer portion to a transfer object. When re-transferring to a transfer layer, it has a function of absorbing or blocking heat at the time of re-transfer, so that a portion of the receiving layer to which the transfer is not easily performed is formed easily and surely.

[0010] In the present invention, in a printed matter on which an image is formed using an intermediate transfer recording medium having a portion on which a release layer and / or a receiving layer is not provided on a base film, the receiving layer is not transferred to the printed matter. It has a region. This is to form a portion where at least one of the release layer and the receiving layer is not provided on the intermediate transfer recording medium provided with the receiving layer via the release layer as necessary on the base film. When the image is transferred to the object to be transferred including the portion, the portion forms a region where the receiving layer is not transferred. Further, in a printed matter image formed using an intermediate transfer recording medium provided with at least a transfer portion comprising a receiving layer so as to be peelable on a base film, a masking layer is formed in or on the layer of the transfer portion. A feature of the present invention is that a portion that is not partially transferred to the transfer medium is formed when the image is re-transferred to the transfer medium using the provided intermediate transfer recording medium. This is because, in an intermediate transfer recording medium in which a transfer portion is provided on a base film, a masking layer is provided in or on the layer of the transfer portion, and when the transfer portion is re-transferred to an object to be transferred, the masking is performed. By absorbing or blocking the heat during retransfer, the layer portion can form a portion where the receptor layer is not partially retransferred to the object to be transferred.

The receiving layer 2 is retransferred. At this time, since the masking layer 10 of the intermediate transfer recording medium 11 has a function of absorbing or blocking heat at the time of retransfer of the receiving layer 2, the transferred portion of the masking layer 10 is The transfer layer is not retransferred, and a non-retransferred portion 15 of the receiving layer is formed on the transfer object 5.

The intermediate transfer recording medium 11 shown in the drawing has a transfer portion comprising a release layer 16 and a receiving layer 2 on a base film 6, and a masking layer 10 is provided between the release layer 16 and the receiving layer 2. This is a configuration in which a masking layer 10 is provided in the layer of the transfer portion. However, the masking layer is not limited to the illustrated one, and it is also possible to provide a masking layer on the layer of the transfer portion of the intermediate transfer recording medium (on the receiving layer) or between the base film and the release layer. Further, in the print 1 shown in FIG. 4, only the receiving layer 2 is transferred as the transfer portion 3 onto the transfer target body 5, but is not limited thereto. Such a multilayer may be re-transferred onto the transfer object as a transfer portion.

Hereinafter, the intermediate transfer recording medium used to obtain the print of the present invention will be described first. (Base Film) As the base film 6 used in the intermediate transfer recording medium, the same base film as used in the conventional intermediate transfer recording medium can be used as it is, and there is no particular limitation. Specific examples of preferred base film include thin paper such as glassine paper, condenser paper or paraffin paper, or heat resistance such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polyphenylene sulfide, polyether ketone or polyether sulfone. And stretched or unstretched films of plastics such as polyester, polypropylene, polycarbonate, cellulose acetate, polyethylene derivatives, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyamide, polyimide, polymethylpentene, and ionomer. A composite film in which two or more of these materials are laminated can also be used. The thickness of the substrate film can be appropriately selected depending on the material so that the strength and heat resistance thereof are appropriate, but usually, the thickness of about 1 to 100 μm is preferably used.

(Receiving Layer) The receiving layer 2 is a main part of the transfer portion constituting the intermediate transfer recording medium. On this receptor layer, an image is formed by thermal transfer from a thermal transfer sheet having a color material layer by thermal transfer. Then, the transfer portion of the intermediate transfer recording medium on which the image is formed is transferred to the transfer target, and as a result, a print is formed. For this reason, as a material for forming the receiving layer, a conventionally known resin material which easily accepts a heat-transferring coloring material such as a sublimable dye or a hot-melt ink can be used. For example, polyolefin resins such as polypropylene, halogenated resins such as polyvinyl chloride or polyvinylidene chloride, polyvinyl acetate, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer or polyacrylic acid ester Vinyl resin, polyester resin such as polyethylene terephthalate or polybutylene terephthalate,
Polystyrene resins, polyamide resins, copolymer resins of olefins such as ethylene or propylene and other vinyl polymers, cellulose resins such as ionomers or cellulose diastase, polycarbonates, and the like.In particular, vinyl chloride resins, acrylic -Styrene resins or polyester resins are preferred.

When the receiving layer is transferred to the transfer object via the adhesive layer, the adhesiveness of the receiving layer itself is not always required. However, when the receiving layer is transferred to the transfer receiving member without the interposition of the adhesive layer, it is preferable to form the receiving layer using a resin material having an adhesive property such as a vinyl chloride-vinyl acetate copolymer. The receiving layer is formed by adding one or more materials selected from the above-mentioned materials and various additives as necessary, dissolving or dispersing in a suitable solvent such as water or an organic solvent, and coating the receiving layer. A solution can be prepared by preparing a solution, applying the solution by a gravure printing method, a screen printing method, a reverse coating method using a gravure plate, or the like, followed by drying. Its thickness is 1 when dry
About 10 g / m ² .

(Release Layer) In the intermediate transfer recording medium used in the present invention, a receptor layer can be formed on a base film via a release layer 7. By having this release layer, the transfer layer mainly composed of the receiving layer can be reliably and easily re-transferred from the intermediate transfer recording medium to the transfer receiving body. The release layer is, for example, microcrystalline wax, carnauba wax, paraffin wax, Fischer-Tropsch wax, various low-molecular-weight polyethylene, wood wax, beeswax, whale wax, Ibota wax, wool wax, shellac wax, candelilla wax, petrolactam, and some Waxes such as denatured wax, fatty acid ester, fatty acid amide, silicone wax, silicone resin, fluororesin, acrylic resin, polyester resin, polyurethane resin, cellulose resin, vinyl chloride
It can be formed using a thermoplastic resin such as a vinyl acetate copolymer or a nitrified cotton.

The release layer can be formed from a binder resin and a release material. As the binder resin, thermoplastic resins such as polymethyl methacrylate, polyethyl methacrylate, acrylic resins such as polybutyl acrylate, polyvinyl acetate, vinyl chloride-vinyl acetate copolymer, polyvinyl alcohol, polyvinyl butyral, etc. Vinyl resin, ethyl cellulose, nitrocellulose,
Cellulose derivatives such as cellulose acetate, or unsaturated polyester resins, polyester resins, polyurethane resins, amino alkyd resins, etc., which are thermosetting resins can be used. Further, as the releasing material, waxes, silicone wax, silicone resin, melamine resin, fluorine resin, fine powder of talc or silica, surfactant, lubrication of metal soap and the like can be used. The release layer was prepared by dissolving or dispersing the above-mentioned necessary materials with a suitable solvent to prepare a release layer coating liquid, and using a gravure printing method, a screen printing method, or a gravure plate on the base film. It can be formed by applying and drying by means such as a reverse coating method. The thickness after drying is usually 0.1 to 10 g / m ² .

The intermediate transfer recording medium used in the present invention, if necessary, prevents fusion of the base film with a heating means such as a thermal head or a heat roll on the surface opposite to the side on which the receiving layer is provided. However, a back layer may be provided to improve the slidability.

(Detection mark) In the intermediate transfer recording medium, the position of the portion where the receiving layer is not provided or the portion where the masking layer is provided can be detected, or transferred to the transfer target on the base film. In order to specify the position of the transfer portion, a detection mark 9 synchronized with these positions can be formed. The form of the detection mark such as the shape and color is not limited as long as it can be detected by the detector.
Examples of the shape include a square shape, a round shape, a bar code, and a line shape from end to end in the width direction of the intermediate transfer recording medium. The color of the detection mark only needs to be detectable by the detector. For example, in the case of a light transmission type detector,
Examples include silver and black having high concealing properties. In the case of a light reflection type detector, a metallic luster color having high light reflection can be used.

A mark using a hologram or a diffraction grating can be used as the detection mark. As a method of forming the hologram mark, a conventionally known method of forming a hologram pattern can be used. For example, an original plate provided with an uneven pattern of interference fringes of a hologram is used to form fine unevenness by embossing. As a sensor for this hologram mark, a so-called hologram sensor can be used.
Light emitted from the light emitting element is irregularly reflected by the hologram mark, and emits diffracted light. The position of the hologram mark can be detected by detecting the diffracted light with the light receiving element.

The position where the detection mark is provided is not limited to the illustrated position. For example, if the film substrate has transparency, the surface of the film substrate opposite to the surface on which the receiving layer is provided is provided. In addition, a detection mark may be provided, or a detection mark may be provided between the film base material and the release layer as a transfer layer of the intermediate transfer recording medium, and the detection mark may be appropriately selected. The detection mark used in the intermediate transfer recording medium is usually formed at one location per screen in synchronization with a portion where the receiving layer is not provided or a portion where the masking layer is partially formed.

(Masking Layer) The masking layer 10 used in the intermediate transfer recording medium is provided in or on the layer of the transfer section of the intermediate transfer recording medium. The layer absorbs or blocks heat at the time of transfer, so that the transfer portion is not transferred to the transfer object. The masking layer is formed by coating the required portion of the intermediate transfer recording medium, or formed by thermally transferring the masking layer from a separate thermal transfer sheet provided with a releasable masking layer on the substrate. be able to. Binder resins used for the masking layer include acrylic resins, acrylic cellulose resins, cellulose resins, polystyrene resins, polyurethane resins, polyester resins, polycarbonate resins, polyamide resins, polysulfone resins, and polychlorinated resins. Vinyl resin, polyvinyl acetate resin, vinyl chloride-vinyl acetate copolymer resin, polyvinyl acetal resin, polyvinyl butyral resin, polyvinyl alcohol resin, epoxy resin, ethylene-vinyl acetate copolymer resin, polyethylene resin, polypropylene resin, etc. Among these resins, those having active hydrogen can be further used as a binder with their crosslinked isocyanates.

A filler can be contained in the masking layer. As the filler, for example, silica,
Inorganic fillers such as alumina, clay, talc, calcium carbonate, barium sulfate, etc., white pigments such as titanium oxide, zinc oxide, acrylic resin, epoxy resin, polyurethane resin,
Resin particles (plastic pigment) such as phenolic resin, melamine resin, benzoguanamine resin, fluororesin, and silicone resin or polyethylene wax, paraffin wax, carnauba wax, microcrystalline wax, wood wax, beeswax, whale wax, ibota wax, wool wax, can Various known wax particles such as delila wax, partially modified wax, and fatty acid amide are exemplified. When the above-mentioned masking layer contains bubbles or a foaming agent or a filler, it is added in an amount of about 0.01 to 200% by weight based on the binder resin of the masking layer.

Further, a porous masking layer having the following sea-island structure can be provided. As a porous manufacturing method,
A wet coagulation method is generally used, in which two or more types of porous forming resin components having greatly different solubility parameters are dissolved in a solvent,
After being applied to the base film, the solvent can be mixed with the solvent, but is passed through a solvent that does not dissolve the resin component, thereby performing solvent replacement. As a result, under the substituted solvent, the solubility parameter of the porous forming resin component is significantly different, so that two or more resins form a sea-island structure. Thereafter, by passing through a heat bath, the island portion of the sea-island structure is further thermally contracted, and porosity progresses. At this time, the island portions become organic fine particles. Then, it is desorbed and dried to obtain a porous masking layer. In the case of this porous masking layer, it is necessary to adjust the size and density of the island portion and the thickness of the non-transfer layer in order to obtain a heat insulating effect. The above masking layer is
By a known coating means such as a gravure coat, a gravure reverse coat, and a roll coat, 0.05 to 5.
It is formed on a substrate at a thickness of about 0 g / m ² as a thermal transfer sheet dedicated to a required portion of an intermediate transfer recording medium or a masking layer.

(Release Layer) In the intermediate transfer recording medium of the present invention, a release layer 16 can be provided in order to improve the releasability of the receiving layer from the substrate film at the time of re-transfer to the object to be transferred. . The release layer is provided when the releasability at the time of thermal transfer of the receiving layer to the transfer receiving body is not sufficient due to the combination of the materials of the base film and the receiving layer. Such a release layer can be formed by using a release agent such as a wax, a silicone wax, a silicone resin, or the like, or a hydrophilic resin described in JP-A-4-142988 or various curable resins. A resin or the like can be appropriately selected and used according to the characteristics of the base film and the non-transfer layer, and is not particularly limited. The release layer is formed by applying an ink prepared by dissolving or dispersing the above-described release agent to a suitable solvent in an appropriate solvent, applying the ink on a base film by a known means, and drying the ink. The thickness can be reduced to 0.1 when dry.
