Description

Transfer paper and manufacturing method thereof

The present invention relates to a transfer paper on which the image to be transferred to the surface of the transfer object is first printed, and in particular, the ink printed on the transfer paper is moved to the surface of the transfer object without being lost in the transfer process, thereby preventing a resolution reduction in the transfer process. It is related to the technology that can improve the transfer speed and simplify the equipment, and ultimately operate in mass production.

In general, manufactured products have various shapes of images on the surface to improve design.

There are various methods of transferring images onto the object surface, such as heating and pressing and non-heating.

Among them, the heat press method is formed in such a manner that the ink printed on the transfer paper adheres to the surface of the transfer object by applying heat and pressure at the same time while keeping the transfer paper on which the image to be transferred is printed on the surface of the transfer object.

In addition, the non-heat transfer method is formed in such a manner that the ink of the transfer paper is peeled off from the transfer paper and adhered to the surface of the transfer object by applying an appropriate pressure in a state where the printing surface of the transfer paper is brought into close contact with the surface of the transfer object.

Existing transfer papers used in these various types of transfer methods are simply a structure in which ink is directly printed on a surface of a base paper made of pulp or synthetic resin, so that the entire ink on the surface of the transfer paper is completely exposed to the atmosphere.

 Therefore, when the transfer paper is transferred by the pressurized heating method, a portion of the ink is easily vaporized and lost during the heating process, which causes a problem that the image resolution of the transferred state is lower than that of the initial state.

In addition, in the non-heat transfer process, peeling between the paper and the ink is not performed smoothly in the process of finally removing the paper, which causes the ink to peel off together with the paper.

In addition, the existing transfer paper is formed in such a way that the ink is directly attached to the surface of the transfer object during the transfer process, and thus, there is a high possibility that the transferred ink may be easily peeled off due to contact with the outside. none.

In addition, since the ink is directly attached to the surface of the transfer object, whether or not the transfer can be limited depending on the material of the transfer object.

Republic of Korea Patent Publication 10-1999-0048575 (1999.07.05)

Hereinafter, specific configurations and effects of the present invention will be described based on the contents illustrated in the drawings.

The transfer paper manufacturing method according to the present invention comprises a large paper preparation step (S100) and coating component preparation step (S200), coating layer forming step (S300) and image printing step (S400) as shown in FIG. do.

First, the paper preparation step (S100) is a preparation process of the base paper 100 that serves as a base of the transfer paper, the base paper 100 is a material that can be printed and coated on the surface, such as a film of pulp or other synthetic resin material and the coating process described later .

Since the paper preparation step (S100) is carried out in the same manner as the general printing paper preparation process, further description is omitted.

In addition, the coating component preparation step (S200) is a process of preparing a coating component 200 for accommodating the ink 1 to be printed and at the same time transferring the ink 1 to the surface of the transfer object in a later transfer process.

At this time, the coating component 200 used is composed of a mixture of the pigment component 210, the adhesive component 220, the fusion component 230 and the peeling component 240.

In this case, the pigment component 222 used functions to contain the ink 1 of the printed image, such as silica, clay, talc, calcium carbonate, cetin white, and the like. The components are used and all of these components can be mixed simultaneously or optionally individually applied.

These pigment components are applied in the form of particles of about 2㎛ to 10㎛ so that sufficient voids 222 are formed between each particle later, so that ink 1 penetrates into the coating layer described later through each void 222 during the printing process. At the same time, the ink 1 is prevented from spreading during the transfer process.

In addition, as necessary, the pigment component 210 may be mixed with a water-resistant resin (not shown) to allow the penetrated ink 1 to be temporarily fixed and to have water resistance, thereby further preventing a bleeding phenomenon.

And the adhesive component 220 is to maintain the entire adhesion of the coating layer 300 including the pigment component 210 on the base paper 100, carboxymethyl cellulose (carboxymethylcellulose), polyvinyl alcohol (polyvinyl alcohol), Components such as latex, acryl, starch and ethyl vinyl acetate are used.

At this time, the content ratio of the adhesive component is maintained at about 5 ~ 10% weight ratio level so as not to adversely affect the peeling efficiency.

In addition, the fusion component 230 serves as a fusion function with a separate connection resin 400 used for connection between the coating layer 300 and the transfer object 500 during the transfer process, the material of the same series as the connection resin 400 Used.

For example, when the material series of the connection resin 400 is a petroleum compound, the same series of components are used.

That is, since the fusion between components of the same series increases, the fusion component and the connection resin are substantially fused together when the coating layer described below is in contact with the connection resin, and eventually the fusion between the coating layer and the connection resin is achieved.

In addition, the peeling component 240 plays a role of smooth peeling between the coating layer 300 and the base paper 100 in the final stage of the transfer, and wax, fluorine, or other silicon-based components are used.

At this time, to maintain the content ratio of the peeling component to about 5 ~ 10% weight ratio level can maintain the proper peeling efficiency between the base paper and the coating layer.

For reference, the reason for including such a peeling component 240 is that the original printing paper is important for the bonding force with the printing ink, the transfer paper of the present invention is the opposite properties, that is, the entire coating component containing the ink in the transfer process This is to be easily torn off from the original paper by a separate connecting resin to be easily moved to the surface of the transfer object.

Of course, the content ratio may be changed as much as the material of the transfer object or the material of the separate connection resin.

For reference, the peeling component 240 may be selectively added depending on the peeling method between the base paper and the coating layer during the transfer process to be described later.

For example, if the entire coating layer is to be completely separated from the base paper, the peeling component 240 is added for smooth separation from each other, while the coating resin is divided by a predetermined thickness according to the depth at which the connection resin described below penetrates into the coating layer. When separated from the base paper, the peeling component does not need to be added.

As such, the coating component 200 is implemented in a form in which each of the functional components described above is completely mixed or formed in a separate layer.

In addition, the coating component is generally transparent or translucent or white so that the ink penetrated into the inside may be sufficiently exposed to the outside to be exposed.

Of course, the color of the coating component is not limited to white, and any color can be applied as long as the color of the ink can be highlighted in contrast with the color of the ink to be printed.

After the coating layer forming step (S300) is carried out by applying the coating component 200 prepared in this way to the surface of the base paper 100 so that the base paper 100 and the coating component 200 is a laminated structure,

As shown in FIG. 3, the coating component 200 is coated on the surface of the base 100 through a coating method such as air-knife or blade, rod-bar, roll coater, comma lip, gravure, or the like. Proceeds.

After a certain period of drying process in this state, a structure in which the coating layer 300 is laminated on the surface of the base 100 is completed as shown in FIG. 4.

At this time, the coating layer 300 is in a state in which a number of micropores are formed by the pigment component, the adhesive layer and the base paper by the adhesive component is maintained at an appropriate level.

The subsequent image printing step (S400) is a process of printing an image to be transferred onto the coating layer 300, and selects from a printing method capable of mass production, that is, a method capable of high resolution, such as rotation printing, gravure printing, or digital printing. Apply.

When the image is printed on the coating layer 300 in this way, the ink 1 is not directly printed on the surface of the paper 100, but penetrates deeply into the coating layer 300 through the pores 222, and the remaining sections are outside the coating layer. The exposed state.

At this time, as described above, since the diameter of the pores is very fine, a phenomenon such as deformation of an image due to gaps between pores does not occur.

As described above, when the color of the coating layer is white, the color of the coating layer may serve as a white ink of the image, so that printing in a natural color form is possible.

And the ink penetrated into the coating layer is maintained in the coating layer by the pigment component of the coating layer, as well as the phenomenon such as bleeding by the water-resistant resin is further prevented.

In addition, the ink may be in the form exposed on the surface of the coating layer in a state that penetrates over the entire thickness of the coating layer or penetrates only about half the thickness as shown in the figure.

For reference, in the image printing step S400, the coating layer 300 should be such that smooth penetration and quick-drying of the ink 1 may be maintained even in a discharge amount of 300% or more and 1440 dpi.

Also, note that the ion trouble between the coating layer 300 and the ink 1 is to be noted. In general, since the printing ink 1 has an anion, the coating layer has a cation, and thus, between the ink 1 and the coating layer. By eliminating the repulsive force so that the ink (1) can be penetrated smoothly into the coating layer to be accommodated, and at the same time to prevent the bleeding phenomenon of the ink (1) when the connection resin 400 and the coating layer 300 is fused in the transfer process.

Hereinafter, the transfer process using the transfer paper produced through this method will be described schematically.

4 and 5, when the connection resin 400 of the same series as the fusion component 230 is coated on the coating layer 300, the connection resin 400 is the fusion component 230 of the coating layer 300. As it is fused with, gradually penetrates into the coating layer 300.

At this time, the connection resin 400 to be applied may be set differently the penetration depth of the connection resin 400 according to the application amount and the penetration time, basically penetrates to the intermediate depth of the coating layer 300 as shown.

In this process, as described above, the ink 1 penetrated into the coating layer 300 is in a state accommodated in the voids of the pigment and fixed by a water-resistant resin, so that no bleeding phenomenon occurs.

Therefore, the connecting resin penetrated into the coating layer becomes like a capsule surrounding the ink.

By the fusion between the connection resin 400 and the fusion component 230 in this way, a section in which the connection resin penetrates in the coating layer 300 is completely fused with the connection resin 400.

When the connection resin 400 is fused to the surface of the transfer object 500 in this state, the entire transfer paper is attached to the surface of the transfer object 500 through the connection resin.

In this state, as shown in FIG. 7, the base 100 and the coating layer 300 are separated from each other. When the peeling component 240 is added to the coating layer 300, the entire coating layer 300 is completely peeled from the base.

And if the peeling component is not added, as shown in Fig. 6, during the peeling process, the connection resin penetrates into the coating layer and the section where the connection resin does not penetrate is divided, and the fusion section is separated from the base while being fused. Sections that do not exist are separated from the sheet together with the sheet attached to the sheet.

That is, in this process, the entire coating layer or the predetermined thickness section containing the ink is peeled off in the form of being separated from the surface of the base by the bonding strength with the connecting resin.

When the base paper is peeled off as described above, the coating layer 300 containing the ink 1 is fused to the surface of the transfer object 500 through the connection resin 400.

As described above, in the present invention, since the ink 1 is transferred to the surface of the transfer object in a state in which the ink 1 is contained in the coating layer, the loss of ink 1 does not occur during the transfer process, and thus the image resolution of the transfer state is lowered. It doesn't work.

In addition, since the ink 1 penetrates into the coating layer, there is no possibility of direct contact with the outside, thereby preventing damage to the image.

In addition, since the coating layer is not directly attached to the transfer object 500, but is attached by fusion between a separate connection resin and the transfer object, the transfer operation may be performed regardless of the material of the transfer object.

The present invention described above may be practiced by various modifications and combinations by those skilled in the art, but such modifications and combinations are not limited to the embodiments described above, but are included in the technical scope of the claims described below to the scope of the present invention You must judge yourself as belonging.
