Abstract

PURPOSE:To easily transfer with a protective film layer on a surface to an arbitrary article by forming a fresh and rigid transfer image on an extremely thin transparent film, and sticking it to an article with the layer surface disposed inside. CONSTITUTION:An image layer is formed on a transfer having a water-soluble sheet as a base, the layer is stuck to an article, and the article is dipped in water to dissolve water-soluble base in the water, thereby transferring the layer to the article. As an image forming method to be used, any one of an electrophotographic method of fixing water-insoluble colorant on the paper base in a nonabsorption state, an electrostatic recording method, an ink jet method, a heat transferring method, etc., can be selected. If the base is coated as required according to the image forming method, if it is water-insoluble, it is transferred to the article integrally with the image layer. In order to stick the layer on the article, an arbitrary one which has high transparency or whiteness is selected by considering operability irrespective of the kind, adhesive or pressure-sensitive adhesive. As the water soluble-sheet, a sheet processed with carboxymethylcellulose is employed.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a transfer method and a transfer medium.

More specifically, the present invention relates to a transfer method and transfer medium for forming clear and strong transferred images on films, cloth materials, metals, glass, plastics, ceramics, wood, etc.

(Prior Art) Conventionally, the following method has been used to retransfer an image fixed onto a transfer body by electrophotography.

That is, a polyester film with a thickness of about 100 microns has been made matte by sandblasting or primer treatment, and a silicone resin is thinly coated on it to temporarily adhere the toner. This is a method in which the object to be transferred is bonded under heat and pressure with a binder sandwiched between them, and then the film is peeled off.

However, this method is very expensive because it uses a special film, it lacks sharpness because some of the toner remains on the film, and it requires high temperatures of about 170°C, so it is not suitable for transfer materials that do not have that tolerance. This method has problems such as being unusable and using a flat-pressure thermocompression bonding machine, making it unusable for three-dimensional objects.

(Problem to be Solved by the Invention) Therefore, an object of the present invention is to solve the problems of the prior art described above, and to provide a transfer method and transfer medium that can form a high-quality transferred image on any transfer target. It is about providing.

(Means for Solving the Problems) As a result of intensive studies, the present inventors bonded the image layer surface fixed on a transfer body based on water-soluble paper to a transfer target, and then attached the water-soluble paper base to It was discovered that by dissolving it in water, a clear and strong transferred image can be formed on the object to be transferred, and this led to the present invention.

That is, the present invention provides the following steps: (1) Forming an image layer on a transfer body based on at least water-soluble paper, laminating the image layer surface with the transfer target, and immersing this laminated body in water to transfer the water-soluble paper base. A transfer method characterized by transferring an image layer to a transfer target by dissolving it in water; (2) the image forming method is an electrophotographic method, an electrostatic recording method, an inkjet method, and/or a thermal transfer method; (3) The transfer method according to (1) above, characterized in that the object to be transferred is a film, cloth material, metal, glass, plastic, ceramic and/or wood.
and (2) the transfer method, and (4) a water-soluble paper used as a base for the transfer member in the transfer methods described in (1), (2), and (3) above.

(Function) Image forming methods that can be used in the present invention include electrophotographic methods, electrostatic recording methods, inkjet methods, thermal transfer methods, etc. in which water-insoluble coloring materials are fixed in a non-absorbing manner on a paper-based transfer member. You can choose which method.

If the necessary coating is applied to water-soluble paper depending on the image forming method, if it is non-water-soluble, it will be transferred to the transfer object as one with the image layer. does not reduce the effects of the present invention in the slightest.

In order to bond the image layer surface to the object to be transferred, any adhesive or pressure-sensitive adhesive can be selected in consideration of workability as long as it has high transparency or whiteness.

As water-soluble paper that can be used in the present invention, Disorbo (produced by Mishima Paper Co., Ltd.), which is made from carboxymethyl cellulose,

(Examples) Hereinafter, the present invention will be explained in more detail based on Examples.

In each of the following examples, an image-fixed transfer member prepared as described below was used.

Using a color copier Digital C-1 (electrophotographic method) manufactured by Matsushita Electric Co., Ltd., the water-soluble paper dissolbo (basis weight 60
A color image was formed on g/r+().

Example 1 A transparent adhesive film (thickness: 32 microns) manufactured by KOKUYO Co., Ltd. was laminated on the image layer surface of the image-fixed transfer body, and then the laminated body was immersed in water for 30 seconds.

Example 2 A laminate film (thickness: 32 microns) manufactured by Meiko Shokai Co., Ltd. was applied to the image layer surface of the image-fixed transfer body and laminated thereon, and then the laminated body was immersed in water for 30 seconds.

As a result, a film was obtained in which only the toner was clearly and firmly fixed.

Example 3 Between the image layer surface of a commercially available plywood board and an image-fixed transfer body (
A saturated polyester hot melt film (thickness 32 microns) manufactured by Toshi Co., Ltd. is sandwiched between the transfer body and the temperature is 130°C.
After bonding by ironing for 10 seconds, the bonded body was immersed in water for 30 seconds.

As a result, a plywood board on which only the toner was clearly and firmly fixed was obtained.

Example 4 Sumitomo 3M Co., Ltd. was applied to the image layer surface of the image-fixed transfer body.

After bonding with the material, the bonded body was immersed in water for 30 seconds.

As a result, a polyester cloth material in which only the toner was clearly and firmly fixed was obtained.

In addition, when commercially available release paper was applied to the image layer side of this polyester cloth material and ironed at 150'C for 15 seconds,
A polyester cloth material that is even more resistant to rubbing and rubbing was obtained.

(Effects of the Invention) According to the present invention, it is possible to form a clear and strong transferred image on an ultra-thin transparent film. It has now become possible to easily perform transfer with a protective film layer on the surface.

Furthermore, since the image layer of the transfer body can be easily and clearly fixed to the transfer target using a binder, it can be applied to any desired coating such as film, cloth, metal, glass, plastic, ceramic, wood, etc. It is now possible to use it by transferring it to a transfer material.
