In addition, the binder may be included in the composition in various contents in consideration of the viscosity, ink adhesion, surface tension, etc. of the ink composition is not particularly limited.

On the other hand, in the present invention "magnetic reaction material" means a material that can implement a variety of patterns in response to the applied magnetic field.

That is, since the ink composition contains such a magnetic reactant, when a magnetic field is applied to the ink composition, a pattern of a predetermined pattern may be formed in response to the applied magnetic field of the magnetic reactant contained in the ink composition. Therefore, when the ink composition as described above is applied to various interior products, it is possible to implement a luxurious and refined appearance that can express a three-dimensional effect.

Here, the magnetic reactant may include any material that can implement various patterns in response to the magnetic field applied according to the purpose of the present invention, for example, iron (Fe), nickel (Ni), cobalt ( Co), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium ( May comprise one or more of lanthanide elements such as Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb) and lutetium (Lu), and includes one or more of the materials exemplified above Alloys or oxides thereof may be used.

Such a magnetic reactant may exhibit deflection in response to an applied magnetic field, and may be uniformly mixed with other components such as a binder included in the ink composition to be dispersed.

Meanwhile, the magnetic reactant may have an average particle diameter of 2 μm to 1 mm, preferably 2 μm to 100 μm, more preferably 2 μm to 50 μm, and most preferably 2 May be in the range of 탆 to 35 탆.

When the particle size of the magnetic reactant is less than 2 μm, it may be difficult to realize a three-dimensional pattern, and when it exceeds 1 mm, the transfer amount of the ink may be lowered.

The nonmagnetic material is not particularly limited and may be used without limitation as long as the material does not react to an applied magnetic field. For example, zinc (Zn), copper (Cu), aluminum (Al), titanium (Ti), One or more selected from the group consisting of ruthenium (Ru) and tantalum (Ta) may be used.

The magnetic reactant contained in the ink composition exhibits deflection in response to the applied magnetic field, and the non-magnetic material is filled in the empty spaces generated through the deflection, thereby forming a pattern of a pattern to effectively visualize the stereoscopic effect. A luxurious and sophisticated appearance that can be expressed can be realized. Therefore, the pattern implementation of the present invention can form a variety of patterns in a desired form, and it is economical because only the magnetic plate (magnetic body) need to be replaced or added without replacing the device (printer) to change the pattern. In addition, various patterns may be formed by using various types of magnetic plates (magnetic bodies).

In addition, FIG. 3 is a cross-sectional view of FIG. 2A. Referring to FIG. 3, the magnetic reactant 1 contained in the ink composition forms a pattern in the form of magnetic force lines due to the application of magnetic force, thereby creating a visual stereoscopic effect. You can add more.

Do it.

The organic solvent may include all materials capable of adjusting the viscosity without limitation, but specific examples thereof include alcohol, acetone, methyl isobutyl ketone or methyl ethyl ketone, and the content thereof is also particularly limited. However, for example, it may be contained in 20 to 30 parts by weight.

When the content of the organic solvent is less than 20 parts by weight, it may be difficult to apply to the printing process as the viscosity of the ink composition increases, and when it exceeds 30 parts by weight, the drying property is greatly reduced and a lot of time is spent in the drying process. There may be a decrease in efficiency because it may take.

Electronic products such as films for electronic devices and the like may be included in this.

In addition, the present invention comprises a first step of applying the ink composition on the substrate surface to the substrate; And a second step of realizing a pattern by applying a magnetic field to the substrate coated with the ink composition.

That is, according to the method for manufacturing the interior film according to the present invention, various patterns can be formed by applying an ink composition containing a magnetic reactant on a substrate and supplying a magnetic force to the substrate, for example, the substrate It is possible to form a three-dimensional pattern of various patterns that can exhibit a three-dimensional effect on the image.

Herein, when the magnetic field is applied to the magnetic reactant according to a predetermined pattern, the `` stereoscopic pattern '' may cause deflection by reacting the magnetic reactant to the portion to which the magnetic field is applied. It can form an appearance that can be represented, it means a pattern that brings about a three-dimensional effect is formed as the magnetic reactant is deflected in response to the applied magnetic field.

On the other hand, the first step of applying the ink composition according to the present invention on a substrate may include all the printing methods commonly known in the art, and is not particularly limited, for example, screen printing, offset printing, gravure Gravure printing or rotary screen printing, which can include a printing or rotary screen printing method, and preferably can be used in a continuous process so that it is suitable for mass production. Gravure printing methods suitable for mass production processes can be used.

The method of applying the ink composition using the gravure printing method is not particularly limited, and may be printed using a general method in the art. For example, (1) the ink on the transfer paper by the gravure printing method. Printing the composition to prepare a transfer sheet having a printed layer formed thereon; And (2) transferring the printing layer formed on the transfer paper to the surface of the substrate.

At this time, the transfer paper in which the printing layer is formed in step (1) may have a structure in which the printing layer, the release layer and the printed layer are sequentially stacked, and the materials and methods constituting the release layer and the printed layer are in this field. Ordinary ones used may be employed.

In addition, the method for transferring the printed layer formed on the transfer layer to the surface of the substrate in step (2) may be used a conventional method used in this field, for example, a thermal transfer method may be used.

In addition, before the printing layer is transferred to the surface of the substrate in the step (2), the method may further include forming an adhesive treatment layer on the surface of the substrate to be transferred.

The adhesive treatment layer may improve the adhesion of the printing layer including the substrate and the binder. The material constituting the adhesive treatment layer is not particularly limited, and a general adhesive resin used in this field may be used without limitation, but considering compatibility and adhesiveness with a binder contained in the ink composition forming the print layer. Can be used.

For example, when an acrylic resin is used as the binder, it is preferable to use an acrylic resin (ex. Methyl (meth) acrylate) as the material constituting the adhesive treatment layer.

The gravure printing method is a typical concave plate printing method, which fills an ink composition in a concave cell and prints the ink composition on a substrate passing therethrough by rotation of a printing roller. According to the gravure printing method as described above, the expressiveness of the color is richer than other printing methods, it is possible to implement a more sharp and fine pattern, it is excellent in the continuity of the work is suitable for mass production.

On the other hand, in the first step, the ink composition may be printed by a rotary screen printing method, and the method of printing the ink composition using the rotary screen printing method is not particularly limited, and general methods in this field may be used. Although it may be printed by, for example, the ink composition may be introduced into a cylindrical screen net as a raw material, and the printing surface may be coated by centrifugal force by rotation.

Such a rotary screen printing method is advantageous for thick film printing, and when the thickness of the screen net is made thick, there is an advantage that it is suitable to form a thick protruding pattern.

On the other hand, the method of applying the magnetic field in the second step is not particularly limited, but may include any method that can form a pattern by applying a magnetic field according to a predetermined pattern, for example, a magnetic roll, a magnetic chuck ( The magnetic field can be applied by a magnetic body such as a chuck) or a magnetic plate.

As a specific example, the magnet roll may be a magnet formed on a roller made of a nonmagnetic material (ex teflon, etc.) according to a predetermined pattern, and as described above, the substrate on which the ink composition is printed to form a printed layer may be uniformly formed. When passing on the patterned magnet roll, the magnetic reactant contained in the ink composition may react to form a pattern having a three-dimensional effect according to the pattern formed on the magnet roll.

Further, in the case of applying a magnetic field using a magnetic chuck, for example, the ink composition is printed to move a substrate on which a printing layer is formed through a conveyor belt or the like, and a magnetic chuck provided on the conveyor belt is placed on the printing layer. The magnetic field is applied while reciprocating in the left and right or front and rear directions according to a predetermined pattern, and thus the magnetic reactant reacts to form a pattern having a three-dimensional effect.

On the other hand, in the case of supplying magnetic force using a magnetic plate, for example, the magnetic plate may be a magnet formed on a plate made of a non-magnetic material according to a predetermined pattern, as described above, the ink composition is printed and printed By placing the substrate on which the layer is formed under a magnet plate having a predetermined pattern, a pattern having a three-dimensional effect can be formed according to the pattern formed on the magnet plate. In this case, in the case of the magnetic plate formed according to a predetermined pattern in the above, one or two or more may be used, and although not particularly limited, two to ten may be used to form various patterns.

On the other hand, the intensity of the magnetic field applied to the ink composition in the second step is not particularly limited, but may be, for example, 100 gauss (G) to 2000 gauss (G), preferably 300 G to 1500 G have.

If the strength of the magnetic field is less than 100G, it may be difficult to form a pattern of various patterns as described above, if it exceeds 2000G, the strength of the magnetic field is too strong, there is a fear that the shape deformation occurs.

In addition, the second step may further include the step of drying the patterned ink composition.

That is, as described above, when the ink composition printed on the substrate forms a predetermined three-dimensional pattern by the deflection of the magnetic reaction material, it may be dried to manufacture interior products such as interior films having a beautiful appearance.

Here, the drying temperature and time conditions are not particularly limited, and drying temperatures and times commonly used in this field may be applied.
