Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a transfer paper for soap, in which a transfer pattern created by a printing ink containing a sublimable dye is sublimated using heat and pressure. This makes it possible to apply this pressure to a new transfer means that performs transfer.

(Prior art) Conventional soap transfer paper is provided with a release layer that melts when heated on the backing paper, and a protective layer that is separated from the backing paper by melting of the release layer. A transfer pattern is printed on the release layer using printing ink mixed with a dye, and an adhesive layer is provided on the transfer pattern and the mount that protrudes from the pattern. The adhesive layer is bonded to the soap surface, and the transfer pattern containing the vehicle and the protective layer are transferred by the adhesiveness of the adhesive layer, and then heating is applied from the top surface of the mount to remove the release layer. Since the process of melting and peeling off the backing paper not only lifts a small amount of the protective layer from the soap surface, but also leaves behind a transparent vehicle that corners the transferred pattern, which is the free alkali of the soap. Therefore, a vehicle with good alkali resistance must be selected. Since the adhesive layer is on one surface of the transfer paper before the transfer, there are many problems such as the need to protect the adhesive layer when temporarily storing or transporting the transfer paper. have points.

(Problems and solutions to be solved by the present invention) As stated in the prior art section, the conventional soap transfer paper cannot transfer the transferred pattern and protective layer unless it is provided with an adhesive layer. ■ The need to provide an adhesive poses difficulties in manufacturing transfer paper; ■ The printing ink vehicle bonds to the soap surface, making the selection of an alkali-resistant vehicle a must. There are problems such as:

The soap transfer paper of the present invention is heated at 120°C to 200°C on the mount.
A transfer pattern layer is formed by printing with a printing ink containing a sublimable dye that sublimates when heated and pressurized at around ℃, and a sublimation pressurized gas of the dye is passed through the pattern layer, and the layer is separated together with a backing paper. A non-transferable mold release layer is provided on the mold release layer, and the sublimation gas I'++f is permeated onto the mold release layer and deposited on the soap surface. The purpose of this invention is to solve the above-mentioned problem α by using a structure in which a protective layer is provided.

First, a transfer pattern printed using a special dye called a sublimation dye and a vehicle is covered with a non-transferable release layer that is peeled off together with the mount, and the mount and transfer pattern layer are attached to the soap surface after the transfer operation. The third thing is to make sure that no residue remains, and the third thing is to heat and pressurize! The sublimable dye contained in the pattern layer is different from the sublimable dye, which is used to embed a protective layer on the soap surface which softens the surface somewhat by applying pressure. Due to the compatibility characteristics, the non-transitional release layer and the protective layer are peeled off together, and the mount alone is not peeled off by heating as in conventional methods.Fourthly, the non-transitional release layer and the protective layer have some gas pressure. The sublimation dye gas is transferred to the soap surface and permeated to solidify it. After the sublimation dye gas is transferred to the soap surface, the transfer pattern layer remaining on the mount and faded due to the sublimation is removed together with the vehicle. It has the advantage that there is no transfer of the vehicle that causes discoloration to the soap surface. (Example) The attached drawing shows an example of the transfer paper of the present invention, in which (1) is a mount, and a thin permeation prevention film (2) is provided on the upper surface of the drawing to prevent printing ink from seeping into the mount. Since the permeation prevention film (2) is to be peeled off together with the mount (1) and the like, it is not necessary to have heat-melting properties like IS. (3) is a seepage prevention film (2) made of printing ink.
A transfer pattern layer formed by printing on l, the layer (
The printing ink forming 3) is one in which a sublimable dye that sublimes at 120°C to 200°C is mixed with a vehicle. Sublimable dyes are so-called sublimable dyes that do not have a liquid phase depending on temperature, and there are many commercially available dyes that are sublimable.Which of the many sublimable dyes to choose? It is a matter of selection, but if two or more colors are used, the mackerel should be selected from those with similar sublimation temperatures.In the present invention, the sublimation temperature of the sublimable dye is limited to around 120°C to 200°C, because the soap There is a close relationship with the melting temperature caused by heating.In other words, sublimable dyes, which have a sublimation temperature at which soap dissolves slowly, are harmful to the transfer process, so they are excluded, but when heated and pressurized at an appropriate temperature, Sublimable dye is gasified,
At the same time, the soap surface softens slightly due to heat, which is protection 1.
(5) Advantageous for implantable transfer, such a sublimation temperature is welcomed in the present invention. (4) is a non-transfer release layer provided on the mount (1) to cover the transfer pattern layer (3), and is made of an epoxy resin or the like that is compatible with the penetration prevention film (2). (5) is a transfer protective film formed of acrylic resin, cellulose resin, etc., which is incompatible with the non-transfer release layer (a) and allows the layer (4) to be peeled off. All of the layers from the permeation prevention film (2) to the protective film layer (5) are formed into thin films with a thickness of about μ+++m. In addition, the non-transfer release layer (4) and the protective film layer absorb the dye sublimation gas generated from the transfer pattern layer with appropriate gas pressure by heating and pressurizing.
The ability to penetrate and transfer to the surface of the soap (6) is required. Most of the film membranes used in ordinary transfer paper currently in use have the ability to darken, but if there is a film that does not have the above-mentioned performance as a result of experiments, it should not be used.

The soap transfer paper shown in Figure 1 has protection 1 (as shown in Figure 2).
5) was pressed against the surface of the soap (6), a heating plate (7) was applied to the mount (1), and the temperature was 120°C to 200°C for 3 to 20 seconds.

As described above, the protective layer (5) of the soap (6), which has a softened layer on its surface, is pressed into shape by heating with the heating plate (7) as described above, and at the same time, the transfer release layer (4) is heated. The sublimated gas dye generated from the soap (6) on the inner surface of the protective layer (5)
) to form a transfer layer (3a), and then the non-transferred release layer (4) is peeled off from the mount (1) as shown.

The soap transfer paper of the present invention uses a new type of printing ink in which a sublimable dye is mixed in the vehicle, and a new structure in which the entire printed pattern layer is not transferred to the soap surface to perform heat-pressure transfer. , unlike the conventional adhesive layer, which has the property of transferring the pattern to the soap surface under the protective layer, which is transferred in a slightly embedded manner on the soap surface, is not formed at all. This has the effect of making it easier to handle the transfer paper.
