Description

TECHNICAL FIELD The present invention relates to a thermal transfer sheet, a method for manufacturing a decorative sheet, a method for manufacturing a decorative sheet, a decorative article, and a decorative article.

As one method for producing a decorative article, a thermal transfer sheet having a coloring material layer provided on one side of a substrate and a thermal transfer image receiving sheet having a receiving layer provided on one side of another substrate are prepared. In combination, a thermal transfer method for forming a thermal transfer image on a receiving layer of a thermal transfer image-receiving sheet is widely used. The thermal transfer method includes a sublimation thermal transfer method in which a heating means such as a thermal head is used to selectively transfer the colorant contained in the colorant layer of the thermal transfer sheet to the receiving layer of the thermal transfer image receiving sheet, and a heating means such as a thermal head. A melting-type thermal transfer method is known in which a coloring material layer melted or softened by heat is transferred to a receiving layer of a thermal transfer image-receiving sheet layer by layer. According to these thermal transfer methods, a decorative article having a thermally transferred image formed on the receiving layer of the thermal transfer image receiving sheet can be obtained.

Along with the diversification of decorative products, decorative products with thermal transfer images formed on arbitrary support members (for example, card substrates, etc.), instead of decorative products with thermal transfer images formed on the receiving layer of thermal transfer image receiving sheets, are becoming more popular. There are many requests to get. In response to this demand, there has been proposed a method for producing a decorative article using an intermediate transfer medium in which a transfer layer including a receiving layer is provided on one surface of a base material and the receiving layer is positioned on the outermost surface. In the method of manufacturing a decorative product using an intermediate transfer medium, a thermal transfer image is formed on the receiving layer of the intermediate transfer medium located on the outermost surface, and then a support member (an arbitrary object) and the intermediate transfer medium are combined, By transferring the transfer layer including the receiving layer on which the thermally transferred image is formed to the supporting member, the decorative article is obtained in which the transferring layer including the receiving layer on which the thermally transferred image is formed is provided on the supporting member.

By the way, as described above, since the receiving layer is positioned on the outermost surface of the intermediate transfer medium, when the transfer layer including the receiving layer is transferred onto the supporting member, the receiving layer is in direct contact with the supporting member. becomes the layer in contact with Therefore, in order to transfer the transfer layer including the receiving layer onto the support member with good adhesion (transferability), it is necessary to take measures to improve the adhesion of the receiving layer to the support member. be. In other words, it is necessary to impart a function as an adhesive layer to the receiving layer.

Under such circumstances, various proposals have been made for imparting adhesion to the support member to the receiving layer. An intermediate transfer sheet (corresponding to an intermediate transfer medium) having thereon a release layer, a curable protective layer, an intermediate adhesive layer, and an image-receiving/adhesive layer has been proposed. In summary, an intermediate transfer medium has been proposed that includes a receiving layer that functions as an adhesive layer as well as dyeability for colorants. By the way, in order to provide the receiving layer of the intermediate transfer medium as proposed in Patent Document 1 with both the dyeing property of the coloring material and the adhesion to the supporting member, (1) the receiving layer A part of the component having dyeability of the contained coloring material is replaced with a component having adhesion to the support member, or (2) both the dyeability of the coloring material and the adhesion to the support member are improved. It is necessary to include functional components in the receiving layer. However, in the case of the former (1), the content of the component having the dyeability of the coloring material in the receiving layer is reduced by containing the component having adhesiveness to the support member. As a result, it becomes difficult to form a high density thermal transfer image on the receiving layer. In other words, the degree of freedom in designing for improving the dyeability of the colorant of the receiving layer is reduced. In the case of the latter (2), the dyeing property and the adhesion to the support member are acceptable for use in fields requiring higher density and higher adhesion to the support member. It is the present condition that it has not yet been applied to the layer.

Further, when an intermediate transfer medium is used as the decorating body, a step of forming a thermally transferred image on the receiving layer of the intermediate transfer medium, which is the decorating body, may be included before the transfer step.

As the thermal transfer sheet 100 prepared by the manufacturing method of the decorative article of the present disclosure, the thermal transfer sheet 100 of the present disclosure described above can be appropriately selected and used, and detailed description thereof will be omitted here.

A decorating body 200 as an example prepared by the method for manufacturing a decorated article of the present disclosure is an intermediate transfer medium, and the intermediate transfer medium is formed on a base material 201 of the intermediate transfer medium with a transfer layer 210 of the intermediate transfer medium. is provided, and the receiving layer 205 is located on the outermost surface thereof.

Further, the manufacturing method of the decorative article of the present disclosure as an example includes a thermal transfer image forming step of forming the thermal transfer image 150 on the receiving layer 205 of the intermediate transfer medium 200 (see FIGS. 5(a) and 6(a)); A transfer step of combining the intermediate transfer medium 200 and the thermal transfer sheet 100 and transferring the transfer layer 10 of the thermal transfer sheet 100 onto the transfer layer 210 of the intermediate transfer medium 200 (see FIGS. 5B and 6B). and, after the transfer step, an integration step ( 5(c) and 6(c)). 5 and 6 are process diagrams for explaining the manufacturing method of the decorative article of the present disclosure, both of which are schematic cross-sectional diagrams. Note that in the method for manufacturing a decorative article of the present disclosure shown in FIG. A thermal transfer sheet 100 is used. On the other hand, in the method for manufacturing a decorative article of the present disclosure shown in FIG. 6, a thermal transfer sheet 100 is used in which a transfer layer 10 and a coloring material layer 8 are provided on one surface of a substrate 1 in a frame-sequential manner.

For example, when an intermediate transfer medium is used as the decorating body 200, the receiving layer 205 of the intermediate transfer medium 200 can be a receiving layer 205 specialized for the dyeability of the coloring material.

<Decoration body preparation process>
The decorating body preparation step is a process of preparing a decorating body. As an example of the decoration body 200 prepared in this step, as shown in FIG. 210 (see FIG. 7A), or a layered structure in which two or more layers including a receiving layer 205 are stacked, and among the layers exhibiting the layered structure, the receiving layer is the farthest from the substrate 201 of the intermediate transfer medium. An intermediate transfer medium 200 provided with a transfer layer 210 (see FIG. 7(b)) of the intermediate transfer medium on which a layer 205 is located.

(Base material of intermediate transfer medium)
The intermediate transfer medium substrate 201 carries an intermediate transfer medium transfer layer 210 provided on one side of the intermediate transfer medium substrate 201 . The material of the base material 201 of the intermediate transfer medium is not particularly limited, and the material described in the base material 1 of the thermal transfer sheet 100 of the present disclosure can be appropriately selected and used.

A transfer of the transfer layer 210 of the intermediate transfer medium is made onto the member 300 . Therefore, the receiving layer 205 can be designed with a higher degree of freedom without taking measures to improve the adhesion between the transfer layer 210 of the intermediate transfer medium and the support member 300 . For example, in order to form a decorative article having a high-density thermal transfer image, the receiving layer 205 of the intermediate transfer medium 200 may be the receiving layer 205 that focuses on the dyeability of the coloring material.

The method for forming the receiving layer 205 is not particularly limited.

It can be formed by coating and drying. Although the thickness of the release layer 206 is not particularly limited, it is preferably 0.5 μm or more and 5 μm or less.

<Thermal Transfer Image Forming Process>
The thermal transfer image forming step is, as shown in FIGS. 5A and 6A, a step of forming a thermal transfer image on the receiving layer 205 of the intermediate transfer medium 200 prepared above. It should be noted that the intermediate transfer medium 200 in which a thermal transfer image is formed in advance on the receiving layer 205 of the intermediate transfer medium 200 may be used without performing this step.

A heating means is used to transfer the coloring material component contained in the coloring material layer to the receiving layer 205, or to transfer the coloring material layer 8 to the receiving layer 205 to form the thermal transfer image 150. .

The thermal transfer sheet used in the thermal transfer image forming process is the thermal transfer sheet 100 in which the coloring material layer 8 and the transfer layer 10 are sequentially provided on one surface of the substrate 1 as described above. (see FIG. 6(a)), or a conventionally known thermal transfer sheet 100A (see FIG. 5(a)) having a coloring material layer may be used. 5 and 6, the thermal transfer image is formed using a thermal transfer sheet including the transfer layer 10 and the coloring material layer 8, or the thermal transfer sheet including the coloring material layer 8 and the transfer layer 10. The only difference is whether a different thermal transfer sheet is used, and the other points are the same.

<Transfer process>
As shown in FIGS. 5B and 6B, in the transfer process, after the thermal transfer image forming process, the intermediate transfer medium 200 and the thermal transfer sheet 100 are combined to form a transfer layer of the intermediate transfer medium of the intermediate transfer medium 200. This is a step of transferring the transfer layer 10 of the thermal transfer sheet 100 onto 210 . Through this process, an intermediate transfer medium is obtained in which the transfer layer 10 is transferred onto the transfer layer 210 of the intermediate transfer medium so that the heat seal layer 5 is positioned on the outermost surface. In other words, the transfer layer 10 of the thermal transfer sheet 100 is transferred onto the transfer layer 210 of the intermediate transfer medium to obtain a decorative sheet having an adhesive surface.

The transfer layer 10 of the thermal transfer sheet can be transferred by a method using a heating device such as a thermal head, as well as by a hot stamp method, a heat roll method, or the like. Also, the transfer layer 10 can be transferred by a method other than this. The same applies to the transfer of the transfer layer 210 of the intermediate transfer medium by the intermediate transfer medium transfer step.

<Integration process>

Through this process, a decorative article 400 is obtained in which the transfer layer 10 and the transfer layer 210 of the intermediate transfer medium including the receiving layer 205 on which the thermally transferred image 150 is formed are laminated in this order on the support member 300 .

The supporting member 300 used in the manufacturing method of the decorative article of the present disclosure is not limited, and includes plain paper, fine paper, tracing paper, wood, polycarbonate, acrylic resin, acrylonitrile-butadiene-styrene (ABS) resin, polyvinyl chloride, and the like.

It may be integrated, or the entire decoration body 200 may be integrated with the support member 300 . That is, the decoration body 200 may be partly separable or non-separable. Moreover, the decorating body may not have an image or the like. Moreover, it may have transparency. Moreover, it may have various functional layers, for example, various functional layers 6 described in the thermal transfer sheet 100 of the present disclosure.

When an intermediate transfer medium is used as the decoration body 200, the transfer layer 210 of the intermediate transfer medium is transferred to the support member 300 by a thermal transfer method, so that the support member 300 and the transfer layer 210 of the intermediate transfer medium are integrated. can be There is no limitation on the uniting method, and a transfer method other than the thermal transfer method may be used. Alternatively, a transfer method such as an in-mold transfer method, a TOM (Three Dimension Overlay Method) molding transfer method, a water pressure transfer method, or a pressure-sensitive transfer method may be used.
