Description

Decal

The present invention relates to a transfer paper, and more particularly, to a transfer paper fabric which can be formed by the user to draw a transfer pattern or picture in ink or paint, or to print and output a computer image through an inkjet printer. will be.

In general, the transfer paper is mainly printed on the transfer paper or factory printing the transfer picture or pattern on the other object, the recent development of a computer and accordingly to form a transfer picture or pattern with a computer image output using a computer printer Warrior map was also shown.

Such a computer image reproducible transfer paper has a merit that a customer can input a transfer paper having a picture or pattern to be transferred to a toy or the like by using a CAD or a scanner into a computer and print it in a short time. However, when printing a picture or a pattern using such a conventional computer image reproducible transfer paper fabric using a wet ink, it is difficult to make the transfer paper clear without smearing the ink.

Accordingly, an object of the present invention is to provide a transfer paper fabric which can be formed by drawing a clear transfer pattern or picture in ink or paint, or by printing a computer image through an inkjet printer.

According to the present invention for solving the above problems, in the transfer paper fabric having a structure in which a release paper, a synthetic resin protective coating layer and a printing layer are sequentially laminated, the printing layer is 30-40% by weight of thermoplastic synthetic resin powder, 3-5% by weight aqueous binder %, 32-45 wt% kerosene, 7-10 wt% volatile accelerator, 7-10 wt% water, 0.5-1.5 wt% ethylene glycol, 0.3-1.0 wt% defoamer, and 0.5-2.0 wt% surfactant There is provided a transfer paper fabric which is formed by applying a printing layer forming solution.

Hereinafter, the present invention will be described in more detail.

In order to form a clear transfer pattern or picture on the transfer paper, it is important that the printing layer of the transfer paper fabric absorbs ink or paint but does not spread. According to the present invention, the printing layer forming liquid applied to the synthetic resin protective coating layer to form the printing layer of the transfer paper fabric is 30-40% by weight of thermoplastic synthetic resin powder, 3-5% by weight of aqueous binder, 32-45% by weight of kerosene, volatile accelerator 7-10% by weight, 7-10% by weight water, 0.5-1.5% by weight ethylene glycol, 0.3-1.0% by weight defoamer and 0.5-2.0% by weight surfactant. If the content ratio of each component of the printing layer forming liquid is out of the above range, the printability is poor and the printing ink may be eluted during washing, so it is preferable to keep it within the above range.

In the printing layer forming liquid of the above composition according to the present invention, the thermoplastic synthetic resin powder preferably has a melting point of 120 ° C or higher. This is because if the melting point of the synthetic resin powder is less than 120 ℃ bad adhesion and easy to separate when washing the transfer. Representative examples of such synthetic resin powders are polyamides. The content of the resin powder in the printing layer forming liquid is 30-40% by weight. The aqueous binder functions to form a stable microporous matrix structure having water absorption by combining with the synthetic resin powder when the printing layer forming liquid is dried. An example of the aqueous binder is an acrylic binder. The preferred content of the aqueous binder in the printing layer forming liquid is 3-5 wt%. Kerosene functions to disperse the synthetic resin powder in the printing layer forming liquid evenly without dissolving, and is a substance which volatilizes when the printing layer forming liquid is dried. The desirable content of the printing layer forming liquid is 32-45% by weight. . The volatile accelerator serves to promote the volatilization of kerosene and to quickly solidify the binder when the printing layer forming solution is dried. An organic solvent, such as gasoline, which does not dissolve the used synthetic resin powder, may be used. The preferred amount of volatile accelerator in the printing layer forming liquid is 7-10% by weight. Ethylene glycol acts as a retarder to prevent the binder from hardening too fast, and its preferred content in the printing layer forming liquid is 0.5 to 1.5% by weight. Water is added to dissolve the aqueous binder to prevent excessive central action of the aqueous binder, the preferred content of the printed layer forming liquid is 7-10% by weight. The antifoaming agent is added to prevent bubbles or the like from occurring during the production of the printing layer forming liquid, and the content thereof in the printing layer forming liquid is 0.3-1.0% by weight. The surfactant is added to the printing layer forming liquid and serves to make the dispersion state of its components uniform. The preferred content of the printing layer forming liquid is 0.5 to 2.0% by weight.

When the printing layer is formed, thermocompression is performed after the printing layer forming solution is dried. In this case, the thermocompression is preferably performed at a temperature of 120 ° C. or less. The reason is that if the temperature is 120 ° C. or more, the surface becomes semi-hollow and loses microporosity and eventually loses hygroscopicity.

In the present invention, the synthetic resin protective coating layer on which the printing layer is formed is a transparent layer which functions as a surface after the transfer and protects the printing layer, and a synthetic resin having such a function is well known in the art.

The release paper has a property that the protective coating layer laminated thereon peels off well after transfer, and may also use a material well known in the art.

As described above, the transfer paper fabric according to the present invention forms a stable microporous matrix structure in which the print layer is combined with the synthetic resin powder and the aqueous binder, so that the ink or paint is absorbed but does not spread, so that the user can transfer the transfer pattern or picture. It can be formed by directly drawing with ink, paint, or the like, or by printing and printing a computer image through an inkjet printer. The transfer sheet on which the transfer pattern or picture is printed is easily transferred to the transfer target by pressing the transfer target or the transfer paper at a temperature of approximately 150-180 ° C. for about 15 seconds.

Features and other advantages of the present invention as described above will become more apparent from the embodiments described below. However, the following examples are not intended to limit the present invention only.

EXAMPLE

After forming a PVC protective coating layer having a thickness of 0.05 mm using a roller on a release paper by a conventional method, a printing layer forming liquid having the following composition was applied on the protective coating layer using a roller, dried, and thermocompressed at a temperature of 80 ° C. It was carried out to form a printing layer having a thickness of 0.06mm to prepare a transfer paper fabric.
