Description

This disclosure relates to a combination of a recording medium and a transfer sheet, and a method for producing a printed matter.

In the production of prints, thermal transfer sheets capable of forming images by various image forming methods are used. Known image forming methods include dye-sublimation thermal transfer and melting thermal transfer. The dye-sublimation thermal transfer method is an image forming method in which a thermal transfer sheet having a dye layer is used, and a sublimation dye contained in the dye layer is transferred to a receiving layer of a thermal transfer image receiving sheet to form an image (for example, Patent Document 1). The dye-sublimation thermal transfer method can control the amount of transfer of the sublimation dye by controlling the amount of energy applied to the thermal transfer sheet, and can control the density gradation. The dye-sublimation thermal transfer method can produce high-quality prints. The melting thermal transfer method is an image forming method in which a thermal transfer sheet having a melting layer is used, and heat energy according to image information is applied to the thermal transfer sheet, and the melted layer that is melted or softened by the application of heat energy is transferred layer by layer to form an image. The melting thermal transfer method can produce prints with high density images.

Prints produced by the above methods have a wide range of uses, and there is an increasing demand for prints with innovative designs, etc.

Each step will be described below. Figures 9A and 9B are process diagrams showing an example of the method for producing a printed matter according to the first embodiment of the present disclosure. Although Figures 9A and 9B show an example using a recording medium having the form shown in Figure 2 and a transfer sheet 200 having the form shown in Figure 5, recording media 100 and transfer sheets 200 having various configurations according to the present disclosure may also be used.

<Preparation process>
The preparation step is a step of preparing the recording medium 100 of the present disclosure and the transfer sheet 200 of the present disclosure. In the method for producing a printed matter of the first embodiment of the present disclosure, either or both of the recording medium 100 prepared in the preparation step and the transfer layer of the transfer sheet 200 prepared in the preparation step include one or more components containing a pearl pigment 30. According to the method for producing a printed matter of the first embodiment of the present disclosure, a pearlescent effect can be imparted to at least one of the images 40 formed on the first receiving layer 3 and the image 40 formed on the second receiving layer 70. In addition, a three-dimensional effect can be imparted to at least one of the images 40.
When the recording medium 100 of the present disclosure includes one or more components containing the pearl pigment 30, a pearlescent effect or a three-dimensional effect can be imparted to the image 40 formed on the first receiving layer 3.
When the first transfer layer 60 of the transfer sheet 200 of the present disclosure includes one or more components containing the pearl pigment 30, a pearlescent effect and a three-dimensional effect can be imparted to the image 40 formed on the second receiving layer 70. Furthermore, according to the method for producing a printed matter of the first embodiment of the present disclosure, the effect of the colored layer 65 of the first transfer layer 60 of the transfer sheet 200 of the present disclosure makes it possible to make the texture of the base of the image 40 formed on the first receiving layer 3 different from that of the image 40 formed on the second receiving layer 70, thereby making it possible to provide an innovative design for the printed matter 300 produced.

In the method for producing a printed matter of the preferred first embodiment of the present disclosure, the recording medium 100 prepared in the preparation step is the recording medium 100 of the first embodiment of the present disclosure, and the transfer sheet 200 prepared in the preparation step is the transfer sheet 200 of the first embodiment of the present disclosure. According to the method for producing a printed matter of the preferred first embodiment of the present disclosure, it is possible to impart a pearly feel and a three-dimensional feel to both the image 40 formed on the first receiving layer 3 and the image 40 formed on the second receiving layer 70.

<Transfer process>
The transfer step is a step of transferring the first transfer layer 60 of the transfer sheet 200 of the present disclosure to a portion of the first receiving layer 3 of the recording medium 100 of the present disclosure (see FIG. 9A). The second receiving layer 70 is located at the transfer interface of the first transfer layer 60 of the transfer sheet 200 of the present disclosure, and the second receiving layer 70 is located on the surface of the first transfer layer 60 after transfer.

The transfer method of the first transfer layer 60 is not limited, and may be a thermal transfer method in which energy is applied to the transfer sheet 200, or any other conventionally known transfer method. Examples of thermal transfer methods include a method using a heating device such as a thermal head, a hot stamp method, and a heat roll method. Examples of transfer methods other than those mentioned above include various transfer methods such as a pad transfer method, a press transfer method, an in-mold transfer method, a TOM (Three Dimension Overlay Method) molding transfer method, a water pressure transfer method, and a pressure-sensitive transfer method. The second transfer layer 80 can be transferred in a similar manner.

As an example, a method for manufacturing a printed matter includes a step of providing an adhesive layer on the first transfer layer 60 of the transfer sheet 200 of the present disclosure prior to the transfer step. The adhesive layer may be formed on the first transfer layer 60 by transfer using an adhesive layer transfer sheet to which the adhesive layer can be transferred, or may be formed by attaching an adhesive sheet or adhesive film onto the first transfer layer 60. The same applies to the method for manufacturing a printed matter of the second embodiment of the present disclosure. The same can also be done when providing an adhesive layer on the second transfer layer 80.

<Image forming process>
The image forming process is a process of forming an image 40 on the first receiving layer 3 and the second receiving layer 70 of the recording medium 100 after the transfer process (see FIG. 9B). By passing through this process, a printed matter 300 can be produced.

The image 40 may be formed on the first receiving layer 3 and the second receiving layer 70 by various thermal transfer methods. Examples of the thermal transfer method include a dye-sublimation thermal transfer method and a melting thermal transfer method.
The dye-sublimation thermal transfer method is an image formation method in which a thermal transfer sheet having a dye layer 95 is used, and thermal energy corresponding to image information is applied to the thermal transfer sheet to transfer the sublimation dye contained in the dye layer 95, thereby forming an image 40.
The melting type thermal transfer method is an image forming method in which a thermal transfer sheet having a melting layer is used, thermal energy corresponding to image information is applied to the thermal transfer sheet, and the melting layer melted or softened by the application of thermal energy is transferred layer by layer to form an image 40. An example of the melting layer is a melting ink layer.

When the transfer sheet 200 of the present disclosure prepared in the preparation step has a dye layer 95, an image can be formed on the transfer sheet 200 of the present disclosure. When the transfer sheet 200 of the present disclosure does not have a dye layer 95, a thermal transfer sheet having a dye layer 95 can be prepared separately and an image can be formed on the thermal transfer sheet.

In the combinations of Comparative Examples 3 to 5, the transfer sheet does not have the first transfer layer, so the transfer of the first transfer layer is not performed.

(Image Formation)
After transferring the above first transfer layer, a dye-sublimation thermal transfer printer (S2245, Symphonia Technology Co., Ltd.) was used to form a gray image (128/255 gradation image) on the first receiving layer of the recording medium with a release portion in the combination in Table 1, and on the first transfer layer transferred to a part of the recording medium with a release portion, using the dye layers of each color of the transfer sheet in the combination in Table 1.

(Transfer of the second transfer layer)
After the above image formation, a dye-sublimation thermal transfer printer (S2245, Symphonia Technology Co., Ltd.) was used to transfer the second transfer layer of the transfer sheet of the combination in Table 1 onto a recording medium with a release portion, thereby obtaining printed matter for each of the examples and comparative examples.
