Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an image transfer material formed on any medium 1 such as cloth or paper.

[Prior Art] Conventionally, a method is known in which an image copied from an original image by an electrophotographic method is transferred onto an arbitrary medium such as cloth, wood, or a plastic board. In this method, an image is first formed on a surface-treated sheet using an electrophotographic method. Next, the image-bearing surface of the sheet and the thermoplastic resin surface of the heat-sealable outer sheet in which a thermoplastic resin is supported on release paper are superimposed and bonded together by hot pressing with a heat roller, hot press, or the like. Thereafter, only the surface-treated sheet is peeled off, and only the image is transferred to the heat-adhesive sheet. Part 1, te...
The image surface of the heat-fusible sheet and any medium are superimposed and bonded together by hot pressing, and only the release paper is peeled off. An image transfer material formed by such a method carries an image layer and a thermoplastic resin layer on a medium.

"In the series of methods, the transfer formation of images from electrophotography was described, but thermal transfer, thermal sublimation,
Transfer formation can be similarly performed using each inkjet method.

In addition, a photosensitive pressure-sensitive medium whose surface layer is supported by microcapsules mainly containing a dye precursor, a photocurable resin, and a photopolymerization initiator reacts with the dye precursor contained in the microcapsules to develop color. A method is also known in which a copied image is transferred to an arbitrary medium using a developer medium having a color developer supported on its surface (Cykara one method: The Mead Corporation, USA). (registered trademark). The method involves irradiating the surface of a photosensitive pressure-sensitive medium with light based on image information to selectively harden the microcapsules encapsulating a photocurable resin, and then applying a color developer to the surface of the photosensitive pressure-sensitive medium. By overlapping the media and applying pressure, the uncured microcapsules are destroyed, causing the dye precursor inside and the color developer to react, forming a color image on the developer-supporting surface. . This type of device is known, for example, from Japanese Patent Laid-Open No. 173981/1981. Then, the developer-supporting surface of the developer medium on which the image has been formed and the thermoplastic resin-supporting surface of the heat-fusible sheet, in which a thermoplastic resin is supported on the sheet base material, are superimposed and hot-pressed, and then cooled. After peeling off the support of the color developer medium and transferring only the color developer layer (image layer) of the color developer medium to a heat-fusible sheet, transfer to any medium such as paper, cloth, plastic film, etc.
This method involves adhering a heat-fusible sheet onto which a color developer layer has been transferred, and then peeling off the sheet base material of the heat-fusible sheet. This method is
The adhesion force between the sheet base material of the heat-fusible sheet, the thermoplastic resin, the support of the color developer medium, the color developer layer, and the image-forming object is taken into consideration. '147805
No., Patent Application No. 63-250549, Utility Application No. 849-849
No. 14 and Utility Model Application No. 63-84915, which are clearly stated in the specifications and drawings attached to each application.

[Problems to be Solved by the Invention] However, when an image is transferred onto a medium such as cloth using the above method, although the copied image itself can be transferred,
No further decoration occurs. In addition, when a three-dimensional object such as embroidery, glass beads, or plastic beads is used as a manuscript, it cannot be reproduced by two sets of electrophotography or one-shot Cykara copying, and it lacks realism and decoration, resulting in a decrease in commercial value. There was a problem.

The present invention has been made to solve the above-mentioned problems, and aims to provide an image transfer material that can express three-dimensional objects, is highly decorative, and has high commercial value. Another object of the present invention is to provide an image transfer material that not only faithfully reproduces the original, but also allows additional decorations to be added.

[Means for Solving the Problems] In order to achieve this object, the image transfer material of the present invention is one in which an image carried on a support is transferred to an arbitrary medium, and the image and the medium are It is characterized by forming an intermediate layer with three-dimensional properties between the two.

[Function] According to the present invention having the configuration as described above, a three-dimensional intermediate layer is formed between an image and an arbitrary medium, so that a highly decorative image transfer product is formed.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

First, with reference to FIG. 1, the structure of the image transfer material 1 produced according to this embodiment will be explained.

This image transfer material 1 is constructed by laminating a thermoplastic resin 12b, an image layer 2a, an intermediate layer 22b, and a heat-sensitive adhesive 23 on an arbitrary medium 32. For the image layer 2a, an image outputted by an electrophotographic method, a thermal transfer method, a thermal sublimation method, an inkjet method, a Cykara one-way method, etc. is used, but in this embodiment, an image formed by a Cykara one-way method is used, Below, the process of constructing the image transfer material 1 will be explained step by step.

First, a procedure for forming an image on the color developer medium 2 using the color image forming apparatus M shown in FIG. 4 will be described.

The photosensitive pressure sensitive medium 3 has microcapsules containing a dye precursor and a photosensitive material supported on its surface layer. The photosensitive and pressure sensitive medium 3 is mounted in a roll shape by a supply roll with the microcapsule-carrying surface facing outward in the lower part of the main body of the apparatus M, and is fed toward a take-up roll located to the right in the figure. Between the supply roll and the take-up roll,
An exposure table 8 is arranged below the photosensitive pressure sensitive medium 3.

A light source 5 that illuminates the surface of the document table 4 is provided above the exposure table 8 . Further, a lens 6 is provided between the exposure table 8 and the light source 5 to form an image of the light reflected from the original 4 onto the pressure medium surface of the photosensitive portion 6 . These light source 5, lens 6, and exposure table 8 constitute a means for performing a predetermined exposure process on the photosensitive pressure sensitive medium 3. Further, a color developer medium 2 in which a color developer layer 2a is supported on a support 2b is housed in the device above the winding roll. A pressure roller 7 is disposed between the exposure table 8 and the take-up roll for overlapping the exposed photosensitive pressure-sensitive medium 3 and the color developer medium 2 and developing them under pressure. .

In the color image forming apparatus M configured as described above, the irradiation light from the light source 5 reflected by the original 4 is focused onto the photosensitive pressure sensitive medium 3 by the lens 6. Then, light is imaged on the surface of the photosensitive pressure sensitive medium 3 and exposed on the exposure table 8. Next, by a transport system (not shown), the capsule-carrying surface of the photosensitive pressure-sensitive medium 3 and the developer-carrying surface of the color developer medium 2 are overlapped, and both are pressurized through the pressure roller 7, so that they are not cured. The microcapsules are destroyed, and the dye precursor and developer that flow out react with each other. Then, the color developer layer (image layer) 2a of the color developer medium 2
A color image is formed.

In this embodiment, as shown in FIG. 2, the developer medium 2 used has a structure that can be separated into a support 2b and a developer layer 2a. For the support 2b, a material with relatively good mold releasability, such as glassine paper, polyester film, polyethylene film, or polypropylene film, is selected. In addition, in the color developer layer 2a, a phenolic compound such as p-phenyl-phenol, an aromatic carboxylic acid compound such as salicylic acid, gallic acid, propyltannic acid, etc., is appropriately added to a thermoplastic binder to an extent that does not interfere with color development. Select a mixture of

Next, a process of transferring and forming an image onto the heat-fusible sheet 12 from the color developer medium 2 on which the image has already been formed will be described.

As shown in FIG. 3, the heat-fusible sheet 12 is constructed by supporting a transparent thermoplastic resin 12b on a sheet base material 12a, and the adhesive horn between the sheet base material 12a and the thermoplastic resin 12b is , the support 2 of the developer medium 2 shown in FIG.
Although the adhesion force between the color developer layer 2a and the color developer layer 2a is adjusted to be stronger than that of the adhesive force between the color developer layer 2a and the color developer layer 2a, it has a structure that causes interfacial peeling.

In addition, the sheet profit 12 of the heat-fusible sheet 12 of this example
For a, any type of plastic film or paper can be used as long as it is not deformed by the hot pressure roll described below, but glassine paper coated with a silicone-based mold release agent is particularly preferred. Further, as the thermoplastic resin 12b, ethylene/vinyl acetate copolymer, Ronne ester, vinyl alcohol/vinyl acetate copolymer, vinyl alkyl ether/maleic anhydride copolymer, polyvinyl chloride, vinyl chloride/vinyl acetate Vinyl resins such as copolymers, acrylic resins such as polyethyl acrylate, polybutyl methacrylate, and methyl polycyanoacrylate, styrene resins, polyamide resins, waxes, etc. can be used alone or as a mixture.

In this embodiment, the sheet base material 12a of the heat-fusible sheet 12 is
Using glassine paper treated with silicon as a mold release agent,
Thermoplastic resin 12b contains 8 parts of a 41% emulsion of styrene/acrylic copolymer and 1 part of a 40% emulsion of ethylene/vinyl acetate copolymer.
After coating the thermoplastic resin 12b on the sheet base TR412a with a #12 bar coater (not shown) using a mixture of
(not shown) for 60 seconds with hot air. Then, as shown in FIG. 3, one end of the heat-fusible sheet 12 is bent and bonded so that the thermoplastic resin 12b is on the inside, so that the bonded portion 13 does not become adhesive even when heated. .

This will be a part to be held by hand when peeling off the support 2b of the color developer medium 2 later.

The surface of the color developer layer 2a of the color developer medium 2 on which an image is formed and the thermoplastic resin 12b of the heat-fusible sheet 12 are superimposed, and a heat pressure roller (not shown) heated to around 140°C is used. ) to fuse the color developer medium 2 and the heat-fusible sheet 12 together.

After cooling to room temperature, the support 2b of the color developer medium 2 is
is peeled off, and only the color developer layer 2a is transferred to the thermoplastic resin 12b side of the heat-fusible sheet 12.

In this example, as the developer medium 2, one having a structure in which the support 2b0 and the developer layer 2a can be separated was used for interfacial peeling. However, attached to the application form of Jitsugan No. 63-79364,
By using the image transfer peeling device described in the specification and drawings, the support can be peeled off by applying the physical properties and mechanical relationships of the color developer layer.

Next, the formation of the intermediate layer 22b on the developer layer 2a side of the heat-fusible sheet 12 to which the developer layer 2a has been transferred will be described.

In this example, as shown in FIG.
An intermediate layer sheet 22 supported on the substrate was used.

The sheet base material 22a is made of kraft paper coated with a silicone-based mold release agent, a styrene-modified ethylene/vinyl acetate copolymer is used as a heat-sensitive adhesive, and vinylidene chloride and acrylonitrile are used as blowing agents. Thermal expandable microspheres with a copolymer shell and isobutane encapsulated as an expansion agent were used.

In this embodiment, since only the triangles and hollow squares that are part of the image are to be made into a three-dimensional image, the intermediate layer sheet 22 having the above-mentioned shape is made into a quasi-6i1i. And developer layer (image layer) 2
The developer layer 2a side of the heat-fusible sheet 12 to which a has been transferred,
The intermediate layer 22b side of the intermediate layer sheet 22 is overlapped, and 14
The heat-fusible sheet 12 and the intermediate layer sheet 22 are fused together by being hot-pressed by passing between heat-pressing rollers (not shown) heated to around 0°C. After cooling to room temperature, the sheet base material 22a of the intermediate layer sheet 22 is peeled off, and the intermediate layer 22b is supported on the heat-fusible sheet 12. Moreover, the intermediate layer 22b
In order to impart adhesion to the image portions to which the adhesive is not fused, the entire image is supported with a heat-sensitive adhesive 23 that does not use the heat-expandable microspheres of the intermediate layer 22b described above.

Then, the heat-sensitive adhesive 23 side of the heat-fusible sheet 12 and cloth, which is an arbitrary medium 32, are brought together and hot-pressed. Then, the heat-fusible sheet 12 and any medium 32 are bonded together by the heat-sensitive adhesive 23, and the heat-expandable microspheres expand to form a three-dimensional image. After that, the sheet profit 12a of the heat-fusible sheet 12 is removed, and the image transfer material 1 is removed.
is completed.

The present invention is not limited to the embodiments described in detail below, and various changes can be made without departing from the spirit thereof. For example, if the intermediate layer is used over the entire image, a three-dimensional image transfer product is produced. Additionally, a mixture of heat-sensitive adhesive and glass beads may be used as the intermediate layer on a sheet base material coated with a silicone mold release agent, or a plastic plate or plastic powder may be used instead of glass beads. May be used. Furthermore, although a heat-sensitive adhesive was used in the above embodiments, pressure-sensitive, photosensitive, anaerobic, or other adhesives may be used.

Furthermore, when an intermediate layer having three-dimensional properties that hides the base of any medium is used, a light-colored image can be formed even on a dark-colored medium.

Moreover, the intermediate layer 3- does not need to have an adhesive component as long as it has adhesive properties to a foaming agent, plastic, or any other medium.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, it is possible to provide an image transfer material that can express three-dimensional objects, is highly decorative, and has high commercial value. In addition to faithfully reproducing images, it is also possible to provide image transfers to which further decorations can be added, which is an excellent industrial effect.
