Abstract

PROBLEM TO BE SOLVED: To prevent elongation of an image and crack of a toner in elongation of the image by a method wherein after superimposing a color toner image onto a surface of a material to be transferred, they are pressed by heating with a silicone rubber, the sheet-like base material is separated thereafter, and the color toner image and a thermoplastic resin layer are stuck by transferring onto the surface of the material to be transferred. SOLUTION: A color toner image 5 of a colored design pattern or the like is formed by reproduction with a color electrostatic copying machine on a surface of a thermoplastic resin layer 3. An organic solvent having weak body dissolving power of the degree in which the color toner is not liquified is applied to the color toner image 5, and the color toner image 5 is impregnated therewith. Thereafter, a surface of the inorganic solvent color toner image 5 is superimposed onto a surface of the material 7 to be transferred having a curved surface or the like. Thereafter, it is pressed by heating with a part of a silicone rubber 13 provided in a heating printer 10. Thereafter, both of the color toner image 5 near to a partition layer 2 and a transparent thermoplastic resin layer 3 are stuck by transferring onto the material 7 to be transferred by separating a sheet-like base material.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of laminating a release layer and a transparent thermoplastic resin layer on the surface of a sheet-like base material of various papers, and copying a color toner image on the surface of the thermoplastic resin layer. The present invention relates to a method of transferring a curved surface such as a color copy for transferring and printing this onto the surface of a material to be transferred having a curved surface.

2. Description of the Related Art When a color toner image is transferred onto a surface of a material to be transferred, such as a curved surface, in this type of curved surface transfer method such as color copying, pad printing is generally known. However, according to this method, it is necessary to produce a plate necessary for printing. Therefore, in the case of printing with a small lot, there is a disadvantage that the cost is very high.
In addition, it is necessary to print one color at a time, and in the case of multicolor printing, it takes a great deal of time and effort, and printing of a large area is impossible, and it is used for personalizing small items such as lighters. There are drawbacks such as only

Further, as another method, a printing machine for printing on a curved surface by using silk printing and gravure printing has been seen in some places. If provided. Printing with a small lot has drawbacks such as an improper printing method in terms of economy and efficiency.

[0004]

In order to solve the above-mentioned drawbacks, it is necessary to compare multi-color originals in transfer printing by color copying on articles with a small number of lots in comparison with other methods. Transfer can be performed easily and easily without requiring special techniques. It is an object of the present invention to provide a method for printing on the surface of a material to be transferred having a curved surface or the like by utilizing such advantages of transfer.

[0005]

According to the present invention, in order to achieve the above object, a release layer and a transparent thermoplastic resin layer are laminated on a sheet-like substrate. After a color toner image is copied and formed on the surface of the thermoplastic resin layer, an organic solvent having a weak dissolving power not to form a solution of the color toner is applied to the surface of the color toner image, and the color toner image is impregnated.
Then, after the color toner image of the organic solvent is polymerized on the surface of the material to be transferred having a curved surface or the like, the sheet-shaped base material is peeled after being heated and pressed by the silicon rubber provided in the heating printer, and the color toner image and The thermoplastic resin layer is transferred and adhered to the surface of the material to be transferred. In addition, after a color toner image is formed on the surface of the thermoplastic resin layer by copying, a cotton cloth or the like is impregnated with an organic solvent that melts the thermoplastic resin layer without turning the color toner image into a solution, thereby wiping the surface of the color toner image. I do. Then, after removing the thermoplastic resin layer other than the color toner image, the color toner image is transferred and adhered to the surface of the material to be transferred.

[0006]

Next, the present invention is configured as described above, and when an image color-copied on a plane is transferred to a curved surface, image expansion occurs. For this reason, it is necessary to make the color copy toner flexible. First, a thermoplastic resin layer is coated on the surface of copy paper to be copied, and a color toner image is formed on the surface to prevent the toner image from cracking at the time of elongation. Can be prevented from tearing. In addition, by including an organic solvent in the color toner image, the toner can be made to be agglomerated, and flexibility can be imparted. This facilitates the transfer of the toner image along the curved surface without cracking even if the toner image is elongated.

Release layer: Silicon resin Thermoplastic resin layer: Polyurethane resin Color toner: Ricoh Retail 650 toner Organic solvent ..Isopropyl alcohol Transfer material: methacrylic resin semicircle Transfer temperature: 120 ° C. Press time: 3 seconds The printer to be heated and pressed is a heated silicon rubber with a thickness of about 2 to 10 mm. Silicon rubber has a heat resistance of about 300 ° C., and there are many types having different resilience depending on the application. Therefore, silicon rubber is most suitable for transferring a curved surface or the like.

[0010]

Since the present invention is constructed as described above, there is no need to make a special printing plate as in the case of printing an image on a conventional curved surface, and printing is performed one color at a time. This is effective in solving the drawback that it takes a great deal of trouble and a high cost in the case of multicolor printing. Further, it is suitable for large-volume printing like conventional curved surface printing, but is unsuitable for printing with a small number of lots, and has the effect of being efficient and economical to be used freely even with a small number of lots. . Since a color toner image is copied and formed on the surface of the release layer according to the present invention, on which the transparent thermoplastic resin layer is laminated, this occurs when the copied image is transferred to the surface of a transfer-receiving material having a curved surface. This has the effect of preventing the image from being stretched and preventing the toner from cracking at the time of stretching to prevent the image from becoming unclear. Further, the thermoplastic resin layer has the effects of coating and protecting the surface of the color toner image and also preventing cracking of copy paper or the like serving as a sheet-like base material. Furthermore, since the surface of the color toner image of the present invention is made to impregnate the organic solvent to make the color toner colloid and have flexibility, the toner image does not crack even when the toner image elongates.
There is an excellent effect that the image can be freely transferred along the curved surface.
