Hereinafter, preferred embodiments of the present invention will be described in detail.
<Transfer method>
First, the transfer method of the present invention will be described.
FIG. 1 is a schematic view showing an example of the transfer method of the present invention.
In the transfer method of the present embodiment, a base sheet preparing step for preparing the base sheet 11 and a first ink in which base layer forming particles are dispersed are applied to the base sheet 11 by an ink jet method, and the base layer 12 A base layer forming step for forming the image layer, a second ink applying step for forming the image layer 13 by applying a second ink in which pigment particles are dispersed in the base layer 12 by an inkjet method, and a recording medium 14 are prepared. And a transfer step in which the recording medium 14 and the image layer 13 are arranged to contact each other and at least a part of the image layer 13 is transferred to the recording medium 14.

Incidentally, a transfer sheet (transfer medium) having a configuration in which an image layer that can be thermally transferred is provided on a sheet such as paper or a plastic film has been known. Generally, image layers such as characters and symbols are formed on the sheet by silk screen printing, gravure printing, offset printing or the like by the thermal transfer sheet. The thermal transfer sheet (thermal transfer medium) can record an image on a recording medium by transferring the image layer to a recording medium (transfer target medium).

There is also known a transfer sheet in which such an image layer is formed by ejecting ink onto a sheet by an ink jet method.
However, depending on the type of sheet on which the image layer is formed, the transfer medium has a problem that the image layer is firmly fixed on the sheet surface and the image layer is not sufficiently transferred to the recording medium.
In view of the above problems, the present inventor has intensively studied. As a result, in the transfer step, before the image layer formed on the underlayer is completely fixed to the underlayer, at least a part of the image layer is recorded on the recording medium. As a result, it was found that the above-mentioned problems can be solved by transferring the toner image onto the recording medium, and that the image layer formed on various substrate sheets can be easily transferred to a recording medium.

Hereinafter, each step will be described in detail.
<Base sheet preparation process>
First, as shown to Fig.1 (a), the base material sheet 11 is prepared (base material sheet preparation process).
Examples of the base sheet 11 include paper, such as cloth, film, plain paper, special paper having an ink receiving layer, and the like, for example, a region including a surface to which ink is applied includes various plastics, ceramics, glass, metal, And base materials composed of these composite materials.

By the way, when the substrate sheet 11 having an ink receiving layer is used, it is possible to form the image layer 13 having excellent color developability. However, the image layer 13 is easily fixed on the substrate sheet 11. Therefore, there is a problem that the image layer 13 cannot be sufficiently transferred to the recording medium 14. However, according to the transfer method of the present invention, even a substrate sheet having such an ink receiving layer can be used as the substrate sheet 11 for transfer.

Examples of the base sheet 11 having an ink receiving layer include those having a void layer as an ink receiving layer and those having a swelling layer as an ink receiving layer. Among these, in particular, when a substrate having a swelling layer as an ink receiving layer is used as the substrate sheet 11, a clearer image layer 13 can be formed and the image layer 13 formed on the substrate sheet 11. Can be more reliably transferred to the recording medium 14.

In the present specification, the “void layer” means that, among the components constituting the layer, the proportion of the resin is less than 30%, and is mainly composed of inorganic particles and provided between the inorganic particles or in the inorganic particles. A layer configured to allow liquid to penetrate into the pores. Further, the “swelling layer” is a layer in which 70% or more of the components constituting the layer is a resin, and the resin layer is swollen by the solvent of the ink so that the solvent penetrates into the open pores. I mean.

<Underlayer formation process>
Next, as shown in FIG.1 (b), the 1st ink in which the particle | grains for base layer formation were disperse | distributed is provided to the base material sheet 11, and the base layer 12 is formed (base layer formation process). By forming such an underlayer 12, at least a part of the image layer 13 can be transferred before the image layer 13 is completely fixed to the recording medium 14 in a transfer step described later. That is, the underlayer 12 is a layer having a function of hindering the image layer 13 formed of the second ink described later from being completely fixed to the recording medium 14.

The first ink application method is not particularly limited, and is an inkjet method, a dipping method (including application by a brush, a squeegee, etc.), a bar coating method, a stencil printing method (screen printing method), a relief printing method, and Intaglio printing method and the like can be mentioned. Among these methods, when the ink jet method is used, a step such as preparing a plate is unnecessary, and the underlayer 12 can be easily formed in an arbitrary range. Further, the base layer 12 and the image layer 13 can be formed by the same apparatus.

The underlayer-forming particles are not particularly limited, and examples thereof include pigment particles, hollow particles, and inorganic fine particles (such as titanium oxide and silica). In addition, a hollow particle means the particle | grains which have a hollow structure.
Among these, when hollow particles are used as the underlayer-forming particles, the image layer 13 formed on the base sheet 11 can be more easily transferred to the recording medium 14.

Among the above, when titanium oxide is used as the underlayer-forming particles, the recording medium 1
4 can transfer the image layer 13 formed on the base sheet 11 more easily. Accordingly, the image layer 13 formed on the base sheet 11 can be easily transferred to the recording medium 14 and the color of the image layer 13 can be easily confirmed.
The average particle size of the underlayer-forming particles is preferably 10 nm or more and 1000 nm or less, and more preferably 100 nm or more and 600 nm or less. As a result, it is possible to more reliably prevent the image layer 13 formed with the second ink described later from being completely fixed to the recording medium 14, and the image layer 13 formed on the base sheet 11 can be more reliably prevented. Can be transferred.

The content of the underlayer-forming particles in the first ink is preferably 1% by mass to 30% by mass, and more preferably 5% by mass to 15% by mass. This

By peeling the substrate sheet 11 from the recording medium 14, a part of the image layer 13 is recorded on the recording medium 14.
The recorded matter 100 including the image layer 13 and the recording medium 14 is obtained.

Since the image layer 13 is provided on the underlayer 12, the image layer 13 is not completely fixed to the underlayer 12. For this reason, this process is performed before the image layer 13 is completely fixed to the underlayer. Thereby, at least a part of the image layer 13 can be easily transferred to the recording medium 14.
Note that “before the image layer 13 is completely fixed to the base layer 12” means that the resin component constituting the second ink constituting the image layer 13 is solidified or the second component constituting the image layer 13. This is before the dispersion medium constituting the ink is completely removed by absorption or volatilization on the base sheet 11 side.

More specifically, “before the image layer 13 is completely fixed to the underlayer 12” means that the amount of the liquid component of the second ink constituting the image layer 13 formed on the underlayer 12 is 5 mass. It is preferable to say before it becomes less than or equal to%, and it is more preferable to say before it becomes less than 1% by mass. Thereby, the image layer 13 formed on the base material sheet 11 can be more reliably transferred to the recording medium 14.
