Description

The present invention relates to a heat transfer sheet, a method for manufacturing a decorative sheet, a decorative sheet, a method for manufacturing a decorative product, and a decorative product.

As one of the methods for manufacturing decorative products, a heat transfer sheet having a coloring material layer provided on one surface of a base material and a heat transfer image receiving sheet having a receiving layer provided on one surface of the other base material are used. In combination, a thermal transfer method of forming a thermal transfer image on the receiving layer of the thermal transfer image receiving sheet is widely used. As the thermal transfer method, a sublimation type thermal transfer method in which the color material contained in the color material layer of the thermal transfer sheet is selectively transferred to the receiving layer of the thermal transfer image receiving sheet by a heating means such as a thermal head, or a heating means such as a thermal head. A melt-type thermal transfer method is known in which the color material layer melted or softened by the above is transferred to the receiving layer of the thermal transfer image receiving sheet together with the layers. According to these thermal transfer methods, it is possible to obtain a decorative product in which a thermal transfer image is formed on the receiving layer of the thermal transfer image receiving sheet.

With the diversification of decorative products, not decorative products in which a thermal transfer image is formed on the receiving layer of a thermal transfer image receiving sheet, but decorative products in which a thermal transfer image is formed on an arbitrary support member (for example, a card substrate). There are also many requests to obtain it. In response to this requirement, a method for producing a decorative product 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 located on the outermost surface has been proposed. In the method for producing 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 (arbitrary object) and an intermediate transfer medium are combined. By transferring the transfer layer including the receiving layer on which the thermal transfer image is formed to the support member, a decorative product is obtained in which the transfer layer including the receiving layer on which the thermal transfer image is formed is provided on the support member.

By the way, as described above, since the receiving layer is located 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 directly connected to the supporting member. It becomes a layer in contact with. Therefore, in order to transfer the transfer layer including the receiving layer onto the support member with good adhesion (good transferability), it is necessary to take measures to improve the adhesion of the receiving layer with the support member. is there. 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 to impart adhesion to the support member to the receiving layer. For example, in Patent Document 1, in order to improve the adhesion to the support member, the base material is used. An intermediate transfer sheet (corresponding to an intermediate transfer medium) provided with 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 having a receiving layer having a function as an adhesive layer as well as dyeability of a coloring material has been proposed. By the way, in order to impart both the dyeing property of the coloring material and the adhesion to the support member to the receiving layer of the intermediate transfer medium as proposed in Patent Document 1, (1) the receiving layer is used. A part of the contained component having the dyeing property of the coloring material is replaced with a component having the adhesiveness to the support member, or (2) both the dyeing property of the coloring material and the adhesiveness to the supporting member. It is necessary to include a functional component in the receiving layer. However, in the case of the former (1), by including the component having adhesion to the support member, the content of the component having dyeability of the coloring material in the receiving layer is reduced by that amount. As a result, it becomes difficult to form a highly concentrated thermal transfer image on the receiving layer. In other words, the degree of freedom in design for improving the dyeability of the color material of the receiving layer is reduced. Further, in the case of the latter (2), the dyeability to the extent that it can withstand use in a field where a higher concentration and a higher adhesion to the support member are required, and the adhesion to the support member are accepted. The current situation is that it has not been given to the layers.

<< Manufacturing method of decorative products >>
Hereinafter, with reference to FIGS. 5 and 6 as examples, the decorative body 200 is used as an intermediate transfer medium for the method for manufacturing the decorative product according to the embodiment of the present disclosure (hereinafter, referred to as the method for manufacturing the decorative product of the present disclosure). The case will be mainly described.

The method for producing a decorative product of the present disclosure includes a step of preparing a thermal transfer sheet 100 provided with a transfer layer 10 on a base material 1, a decorative body preparation step of preparing a decorative body, and a decorative body on the decorative body. The process includes a transfer step of transferring the transfer layer of the thermal transfer sheet, and an integration step of integrating the support member 300 and the decorative body 200 via the transfer layer 10 of the thermal transfer sheet 100 after the transfer step. When an intermediate transfer medium is used as the decorative body, a step of forming a thermal transfer image on the receiving layer of the intermediate transfer medium which is the decorative body may be included before the transfer step.

As the thermal transfer sheet 100 prepared by the method for producing a decorative product 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.

The decorative body 200 as an example prepared by the method for producing a decorative product of the present disclosure is an intermediate transfer medium, and the intermediate transfer medium is a transfer layer 210 of the intermediate transfer medium on the base material 201 of the intermediate transfer medium. Is provided, and the receiving layer 205 is located on the outermost surface thereof.

Further, as an example, the method for producing the decorative product of the present disclosure includes a thermal transfer image forming step of forming a 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. 5 (b) and 6 (b)). After the transfer step, the intermediate transfer medium 200 to which the transfer layer 10 of the thermal transfer sheet 100 has been transferred and the support member 300 are combined, and the support member 300 and the transfer layer 210 of the intermediate transfer medium are integrated (integration step). (See FIGS. 5 (c) and 6 (c)). 5 and 6 are process diagrams for explaining the manufacturing method of the decorative product of the present disclosure, and both are schematic cross-sectional views. In the method for producing the decorative product of the present disclosure shown in FIG. 5, a thermal transfer sheet 100A having a color material layer 8 provided on one surface of the base material 1A and a transfer layer 10 provided on one surface of the base material 1 are provided. The heat transfer sheet 100 is used. On the other hand, in the method for producing a decorative product of the present disclosure shown in FIG. 6, a thermal transfer sheet 100 in which a transfer layer 10 and a color material layer 8 are sequentially provided on one surface of a base material 1 is used.

In the method for manufacturing a decorative product of the present disclosure, by forming the heat seal layer 5 of the heat transfer sheet 100 as described above, good adhesion can be imparted to the heat seal layer 5. Therefore, in the method for manufacturing the decorative product of the present disclosure, it is possible to manufacture the decorative product 400 having high adhesion between the decorative body 200 and the support member 300.

Specifically, in the method for producing a decorative product of the present disclosure, the transfer layer 210 of the intermediate transfer medium 200 and the support member 300 are not directly brought into close contact with each other, but are supported by the transfer layer 210 of the intermediate transfer medium 200. Since the member 300 is brought into close contact with the transfer layer 10 including the heat seal layer 5, the transfer layer 210 of the intermediate transfer medium 200 and the support member 300 are brought into close contact with each other due to the effect of the heat seal layer 5. It can be good.

Further, by imparting the adhesive function to the heat seal layer 5 constituting the transfer layer 10, it is not necessary to impart the adhesive function to the decorative body 200 itself, and the degree of freedom in selecting the decorative body 200 is increased. Can be enhanced. For example, when an intermediate transfer medium is used as the decorative body 200, the receiving layer 205 of the intermediate transfer medium 200 can be a receiving layer 205 specialized in dyeability of the coloring material.

<Decorative body preparation process>
The decorative body preparation step is a step of preparing a decorative body. As shown in FIG. 7, the decorative body 200 prepared in this step is a transfer layer of an intermediate transfer medium having a single-layer structure consisting of only a receiving layer 205 on a base material 201 of the intermediate transfer medium. It exhibits a laminated structure in which two or more layers including 210 (see FIG. 7A) or the receiving layer 205 are laminated, and among the layers exhibiting the laminated structure, it receives the farthest from the base material 201 of the intermediate transfer medium. The intermediate transfer medium 200 is provided with the transfer layer 210 (see FIG. 7B) of the intermediate transfer medium in which the layer 205 is located.

(Base material of intermediate transfer medium)
The base material 201 of the intermediate transfer medium holds the transfer layer 210 of the intermediate transfer medium provided on one surface of the base material 201 of the intermediate transfer medium. 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.

(Transfer layer of intermediate transfer medium)
As shown in FIG. 7, a transfer layer 210 of the intermediate transfer medium is provided on at least a part of one surface of the base material 201 of the intermediate transfer medium. The transfer layer 210 of the intermediate transfer medium may exhibit a single-layer structure composed of only the receiving layer 205, or may exhibit a laminated structure in which two or more layers including the receiving layer 205 are laminated. The transfer layer 210 of the intermediate transfer medium in the intermediate transfer medium 200 of the form shown in FIG. 7B has a laminated structure in which the release layer 206 and the receiving layer 205 are laminated in this order from the base material 201 side of the intermediate transfer medium. Is presenting. When the transfer layer 210 of the intermediate transfer medium exhibits a laminated structure, the layer located farthest from the base material 201 of the intermediate transfer medium among the layers constituting the transfer layer 210 of the intermediate transfer medium receives. It becomes layer 205.

(Receptive layer)
The receiving layer 205 constituting the transfer layer 210 of the intermediate transfer medium is located on the outermost surface of the intermediate transfer medium 200. The receiving layer 205 is not particularly limited, and any receiving layer 205 used in the field of intermediate transfer media can be used. As an example, the receiving layer 205 is made of a polyolefin such as polypropylene, polyvinyl chloride, or a halogenated resin such as polyvinylidene chloride, polyvinyl acetate, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer or polyacrylic. Vinyl resin such as acid ester, polyester such as polyethylene terephthalate or polybutylene terephthalate, copolymer of olefin such as polystyrene, polyamide, ethylene, or propylene with other vinyl polymer, ionomer, cellulose resin such as cellulose diastase, polycarbonate , Epoxy resin, etc. are contained. The receiving layer 205 in a preferred form contains polyvinyl chloride, acrylic-styrene resin, and polyester. Above all, a receiving layer containing a vinyl chloride-vinyl acetate copolymer is preferable in that a high-concentration thermal transfer image can be formed on the receiving layer.

In the method for producing a decorative product of the present disclosure, the transfer layer 210 of the intermediate transfer medium and the support member 300 do not come into direct contact with each other, but are supported via the transfer layer 10 including the heat seal layer 5 described above. The transfer layer 210 of the intermediate transfer medium is transferred onto the member 300. Therefore, the receiving layer 205 can be made into a receiving layer 205 having an increased degree of freedom in its design without taking measures for increasing 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 product having a high-concentration thermal transfer image, the receiving layer 205 of the intermediate transfer medium 200 may be the receiving layer 205 whose main focus is the dyeability of the coloring material.

The method for forming the receiving layer 205 is not particularly limited. For example, a coating solution for a receiving layer in which the resin material exemplified above is dispersed or dissolved in an appropriate solvent is prepared, and this coating solution is used as an intermediate transfer medium. It can be formed by coating and drying on the base material 201 or on an arbitrary layer provided on the base material 201 of the intermediate transfer medium. The thickness of the receiving layer 205 is not particularly limited, and is usually 1 μm or more and 10 μm or less.

(Peeling layer)
As shown in FIG. 7B, in order to improve the peelability of the transfer layer 210 of the intermediate transfer medium when the transfer layer 210 of the intermediate transfer medium is transferred from the base material 201 of the intermediate transfer medium, the intermediate transfer medium is used. A release layer 206 (sometimes referred to as a protective layer) may be provided between the base material 201 and the receiving layer 205. The release layer 206 constitutes the transfer layer 210 of the intermediate transfer medium, and is located closest to the base material 201 of the intermediate transfer medium among the layers constituting the transfer layer 210 of the intermediate transfer medium.

As an example, the release layer 206 includes waxes, silicone wax, silicone resin, silicone-modified resin, fluororesin, fluorine-modified resin, polyvinyl alcohol, acrylic resin, heat-crosslinkable epoxy-amino resin, heat-crosslinkable alkyd-amino resin, and the like. Contains. The release layer 206 may contain one kind of resin alone, or may contain two or more kinds of resins.

The method for forming the release layer 206 is not particularly limited, but the above resin is dissolved or dispersed in an appropriate solvent to prepare a coating solution for the release layer, and this coating solution is applied onto the base material 201 of the intermediate transfer medium. Can be formed by coating and drying. The thickness of the release layer 206 is not particularly limited, but is preferably 0.5 μm or more and 5 μm or less.

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

Specifically, the receiving layer of the intermediate transfer medium 200 and the thermal transfer sheet (100, 100A) having the coloring material layer 8 are superposed so that the receiving layer 205 and the coloring material layer 8 face each other, such as a thermal head. This is a step of forming the thermal transfer image 150 by transferring the color material component contained in the color material layer to the receiving layer 205 or transferring the color material layer 8 to the receiving layer 205 by using the heating means of the above. ..

The thermal transfer sheet used in the thermal transfer image forming step is performed by using 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 base material 1 described above. Alternatively, a conventionally known thermal transfer sheet 100A having a color material layer (see FIG. 5 (a)) may be used instead of this (see FIG. 6 (a)). 5 and 6 show that the thermal transfer image is formed by using the thermal transfer sheet including the transfer layer 10 and the color material layer 8, or the thermal transfer sheet having the color material layer 8 and the transfer layer 10 is provided. They differ only in that they are performed using different thermal transfer sheets, and are otherwise consistent.

<Transfer process>
In the transfer step, as shown in FIGS. 5 (b) and 6 (b), after the thermal transfer image forming step, the intermediate transfer medium 200 and the thermal transfer sheet 100 are combined, and the transfer layer of the intermediate transfer medium of the intermediate transfer medium 200 is combined. This is a step of transferring the transfer layer 10 of the thermal transfer sheet 100 onto the 210. By going through this step, an intermediate transfer medium obtained by transferring the transfer layer 10 onto the transfer layer 210 of the intermediate transfer medium so that the heat seal layer 5 is located on the outermost surface thereof is obtained. 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 adhesiveness on its surface.

For the transfer of the transfer layer 10 of the thermal transfer sheet, in addition to a method using a heating device such as a thermal head, for example, a hot stamp method, a heat roll method, or the like can be used. Further, the transfer layer 10 can also 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>
In the integration step, as shown in FIGS. 5 (c) and 6 (c), the intermediate transfer medium 200 in which the transfer layer 10 is transferred onto the transfer layer 210 of the intermediate transfer medium and the support member 300 are combined. This is a step of transferring the transfer layer 210 of the intermediate transfer medium onto the support member 300 together with the transfer layer 10 to integrate the support member 300 and the transfer layer 210 of the intermediate transfer medium. Through this step, a decorative product 400 is obtained in which the transfer layer 210 of the intermediate transfer medium including the transfer layer 10 and the receiving layer 205 on which the thermal transfer image 150 is formed is laminated on the support member 300 in this order.

The support member 300 used in the method for producing the decorative product of the present disclosure is not limited, and is not limited to plain paper, high-quality paper, tracing paper, wood, polycarbonate, acrylic resin, acrylonitrile, butadiene, styrene (ABS) resin, polyvinyl chloride, etc. Examples thereof include a resin plate (which may be a film), a metal plate such as aluminum, a glass plate, and a ceramic plate such as pottery. Further, as the support member 300, a member having a predetermined image can also be used. Further, as the support member 300, a member having a curvature can also be used.

Further, for the integration of the decorative body 200 and the support member 300, a decorative body 200 whose part can be separated is used as in the intermediate transfer medium, and a part thereof is separated from the support member 300. It may be integrated, or the entire decorative body 200 may be integrated with the support member 300. That is, a part of the decorative body 200 may be separable or inseparable. Further, the decorative body may not have an image or the like. Moreover, it may have transparency. Further, 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 decorative body 200, the support member 300 and the transfer layer 210 of the intermediate transfer medium are integrated by transferring the transfer layer 210 of the intermediate transfer medium to the support member 300 by a thermal transfer method. Can be converted. The means of integration is not limited, and a transfer method other than the thermal transfer method may be used. Further, a transfer method such as an in-mold transfer method, a TOM (Three dimension Overlay Method) molding transfer method, a hydraulic transfer method, or a pressure-sensitive transfer method may be used.
