Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming method for transferring and forming an image on an image forming body such as cloth, paper, wood and plastic.

[0002]

2. Description of the Related Art Conventionally, as a method for transferring and forming an image formed on a support by an output device onto an image forming body, for example, an image copied from an original image by an electrophotographic method is used as a cloth, wood, or plastic. A method of transfer-forming on an arbitrary medium such as a plate is known from JP-A-60-92897. In that method, first, an image is formed by an electrophotographic method on a sheet whose surface is treated so as to be easily peeled off. Next, the image surface of the sheet and the thermoplastic resin surface of the heat-fusible sheet carrying a transparent thermoplastic resin on the release paper are superposed and bonded by heating and pressing with a heat roller or hot press. After that, only the surface-treated sheet is peeled off and only the image is transferred to the heat-fusible sheet.
Then, the image surface of the heat-fusible sheet and an arbitrary medium are superposed and heated and pressed to bond them, and only the release paper is peeled off.

Although the above-mentioned method describes the transfer and formation of the image by the electrophotographic method, the transfer and the formation can be similarly performed by each method such as the thermal transfer method, the thermal sublimation method and the ink jet method.

Further, a photosensitive pressure-sensitive medium in which microcapsules containing a dye precursor, a photocurable resin and a photopolymerization initiator as main inclusions are carried on the surface layer, and a dye precursor which is an inclusion of the microcapsules reacts with each other. Also known is a method of transferring and forming an image formed using a substance that develops color, that is, a developer medium in which a so-called developer is carried on the surface layer, to an arbitrary medium. The method is to irradiate light on the surface of the light and pressure sensitive medium based on image information to selectively cure the microcapsules containing the photocurable resin, and then to develop the color developer on the surface of the light and pressure sensitive medium. By overlapping and pressurizing the medium, the uncured microcapsules are destroyed, thereby reacting the dye precursor inside and the developer to form a color image on the surface of the developer.

An apparatus of this kind is disclosed in, for example, Japanese Patent Laid-Open No. 63-18.
It is known from the 8070 publication. Then, the developer surface of the developer medium on which the image is formed and the thermoplastic resin-supported surface of the heat-fusible sheet in which the thermoplastic resin is carried on the sheet base material are superposed and heated and pressed, After cooling, the support of the developer medium is peeled off and only the developer layer (image layer) of the developer medium is transferred to the heat-fusible sheet, and then it is applied to any medium such as paper, cloth, plastic film, etc. A method of adhering a heat-fusible sheet onto which a developer layer has been transferred, and peeling the sheet base material of the heat-fusible sheet. This method takes into consideration the adhesive force between the sheet base material of the heat-fusible sheet, the thermoplastic resin, the support of the developer medium, the developer layer, and the image-forming material. It is specified in Japanese Patent Laid-Open No. 2-3390, Japanese Patent Laid-Open No. 2-97947, Japanese Utility Model Laid-Open No. 2-10062, and Japanese Utility Model Laid-Open No. 2-10063.

[0006]

However, for example, when characters such as an alphabet are listed in an image,
When an image formed on a support by the above output device is transferred and formed on the image forming body by the method of transferring and forming the image on the image forming body, the heat-fusible sheet on which the image is transferred is formed on the image forming body. The character portion of the heat-fusible sheet must be cut out before adhering to the body, which is troublesome and time consuming. In addition, it does not take a relatively long time to cut out a circle or a square around a character without cutting it out according to the shape of the character. As it is carried, the aesthetic appearance is impaired and the commercial value is reduced. Further, the image has to be formed on a special sheet which is surface-treated so as to be easily peeled off, which leads to an increase in cost.

The present invention has been made in order to solve the above-mentioned problems, and provides an image forming method for forming an image formed product which does not spoil the appearance in a short time even when the image is characters and figures. Especially.

[0008]

In order to achieve this object, the image forming method of the present invention is carried out by supporting a thermoplastic resin on a colored portion of an image formed on a support and superposing it on a sheet substrate. The thermoplastic resin and the image are transferred to the sheet base material by peeling the support after heating and pressurizing to adhere, and the image surface of the sheet base material and the image forming body are superposed and heated. The gist is to remove the sheet base material from the image forming body by applying pressure to adhere the thermoplastic resin to the colored portion of the image formed on the support. Place a screen sheet with the same image on the body, squeeze with a solution in which the thermoplastic resin is dispersed or dissolved in a solvent, remove the screen sheet and dry to form an image using an electrophotographic method. It And wherein the on the support is a method of supporting a thermoplastic resin. Further, in the image forming method, a heat-sensitive adhesive may be inserted when the image surface of the heat-fusible sheet and the image forming body are superposed and heated and pressed.

A developer medium 12 having a developer layer supported on a support is housed above the winding roll in the apparatus. A pressure roller pair 17 is arranged between the exposure table 18 and the take-up roll for pressure-developing the photosensitive pressure-sensitive medium 13 that has been subjected to the exposure process and the developer medium 12 in a superimposed manner. There is.

Color copying machine M constructed as described above
The light emitted from the light source 15 reflected by the original 14 is condensed by the lens 16 onto the photosensitive pressure-sensitive medium 13. Then, light is imaged on the surface of the photosensitive pressure-sensitive medium 13 and is exposed on the exposure table 18. Next, the capsule-carrying surface of the photosensitive pressure-sensitive medium 13 and the developer-carrying surface of the color-developing medium 12 are superposed by a transport system (not shown), and both are pressed through the pressure roller pair 17 to be cured. The microcapsules that were not present are destroyed, and the dye precursor that has flowed out thereby reacts with the developer. Then, a color image is formed on the developer layer of the developer medium 12.

In this embodiment, as shown in FIG. 3, the developer medium 12 has a structure in which the support 12b and the developer layer 12a can be separated from each other. The support 12b includes

Next, the process of supporting the thermoplastic resin on the colored portion of the image formed on the developer medium 12 will be described.

First, a screen sheet 6 having a heat-sensitive resin layer 6e carried on a mesh 6d of nylon, polyester, stainless steel or the like, as shown in the enlarged portion of FIG. 5, is generally available on the market. According to the information of all colored parts of the image to be finally formed, the mesh 6
The heat-sensitive resin between d was melted to make a plate. In particular,
The image was read by a scanner, the colored portion of the image was determined using a computer, and the determined portion was plate-made on a screen sheet using a thermal printer. Therefore, holes are formed on the screen sheet 6 between the meshes of the portions 6a, 6b, 6c corresponding to the colored portions of the original image as shown in FIG.

Next, the screen-finished screen sheet 6 was superposed on the developer medium 12 while aligning the images, and the squeegee of the polyolefin resin serving as the thermoplastic resin 22 was squeezed. Then, the screen sheet 6 was separated and dried. In this way, the thermoplastic resin 22 is supported.

In this embodiment, as the thermoplastic resin 22, ethylene / vinyl acetate copolymer, rosin ester, vinyl alcohol / vinyl acetate copolymer, vinyl alkyl ether / maleic anhydride copolymer, polychlorinated resin are used. Vinyl, vinyl resin such as vinyl chloride / vinyl acetate copolymer, polyethyl acrylate, polybutyl methacrylate,
It can be used as a solution in which an acrylic resin such as methyl polycyanoacrylate, a styrene resin, a polyamide resin, a simple substance such as a wax and a mixture thereof are dispersed or dissolved in a solvent.

Developer medium 1 carrying a thermoplastic resin 22
The thermoplastic resin 22 side of No. 2 and the polyethylene terephthalate film which is the sheet base material 23 are overlapped 140
The heat-fusible sheet 22 and the developer medium 12 are fused to the sheet base material 23 by passing through a hot-pressing roller (not shown) heated to around 0 ° C. and thermocompression bonding. Then, after cooling to room temperature, the support 12b of the developer medium 12 is peeled off, and as shown in the perspective view of FIG. 6, an image of the thermoplastic resin 22 and the developer layer 12a is formed on the sheet base material 23. Only the part is transferred.

In this embodiment, the developer medium 12 having a structure in which the support 12b and the developer layer 12a are separable is used for the interface peeling, but the developer is not easily separable at the interface. By using the peeling device for image transfer described in Japanese Utility Model Laid-Open No. 2-2166, the support can be peeled from the developer medium by applying various physical properties and mechanical relations of the developer layer.

Next, in this embodiment, although not necessary depending on the composition of the developer layer and the member to be imaged, the sheet substrate 2 on which the thermoplastic resin 22 and the developer layer 12a are transferred.
The adhesive layer 32 is formed on the developer layer 12 a side of No. 3. This is formed in order to more firmly bond the developer layer 12a and the cloth 2. As a method for forming, a dispersion of a polyolefin resin is squeezed on the developer layer 12a using the screen sheet 6 as in the case where the developer medium 12 is loaded with the thermoplastic resin. Then, the screen sheet 6 was separated and dried.
In this way, a transfer sheet is produced in which the thermoplastic resin 22, the developer layer 12a which is an image, and the heat-sensitive adhesive 32 are formed on the sheet base material 23.

A cloth 2 as an image forming body is placed on a base (not shown) of a thermocompression bonding machine, and the transfer sheet is placed on the cloth 2 so that the heat-sensitive adhesive 32 faces the cloth 2.
Pressed for 20 seconds at 0 g / cm ² . After that, the sheet base material 23 was separated from the fabric 2. By doing so, the heat-sensitive adhesive 32 and the thermoplastic resin 22 are melted, and the developer layer 12a and the fabric 2 are bonded to each other.

The image-formed product 1 produced by the image-forming method of the present invention is completed as described above.

Although the output image of the color copying apparatus is used in the above embodiment, the image output by the printer may be used.

The same image transfer material as described above can be produced by the image forming method of the present invention from an image formed by an electrophotographic method, a thermal transfer method, a thermal sublimation method, an ink jet method or the like. Among them, the toner when the electrophotographic method is used and the ink when the thermal transfer method is used correspond to the heat-sensitive adhesive, and the heat-sensitive adhesive in the above-mentioned embodiment is not necessary.

In the above embodiment, squeegeeing was carried out using a screen sheet and a liquid resin as a method for supporting the thermoplastic resin on the developer medium, but as another method, a copying machine using an electrophotographic system is used. There is also a method of using a transparent toner to carry the toner. For example, if a digital copying machine is used, an original image is placed on an original table, and a copy is made on a developer medium using a toner made of a thermoplastic resin, the thermoplastic resin is carried only on a colored portion of the image. You can Further, in order to carry the heat-sensitive adhesive, a copy of a mirror image may be prepared on the image formed on the sheet base material by using the copying machine and the toner.
