1 is a view for explaining a process of manufacturing a composite pattern mold for manufacturing a design decoration film.

Design decoration film can be produced by a composite pattern mold.

In order to manufacture the composite pattern mold, a method such as engraving processing using a bite on a substrate layer may be utilized. For example, a primary pattern can be formed by performing cutting using a bite to a Cu, Ni, Cr, Sus base material, etc., and forming patterns such as prisms, lenticulars, pyramids, lenses, cones, holograms, etc. (Step 101) . This primary pattern has a geometric optical effect and has a size greater than or equal to micrometers.

On the other hand, in the composite pattern mold, a secondary pattern may be formed on the primary pattern (step 102). Such a secondary pattern may be implemented as a hologram, gradation, haze, etc., and may be formed through methods such as laser, ion beam, plasma, deposition, sand blaster, merging, and the like.

The secondary pattern of the composite pattern mold according to an embodiment may be formed on the entire surface or only a portion of the pattern, and an isotropic or anisotropic effect may be realized.

The mold in which both the primary pattern and the secondary pattern are formed may be formed as a composite pattern mold (step 103).

The compound pattern mold can implement a compound pattern effect. For example, the primary pattern has a size greater than or equal to micrometers, thereby having the effect of geometric optics. In addition, the secondary pattern may have the effect of wave optics on the surface of the primary pattern and be formed as a secondary pattern having a size of micro or less.

The geometric optical effect appearing on the design decoration film by the primary pattern of the composite pattern mold may include at least one or more effects of light going straight, reflecting, and refraction.

In addition, the wave optical effect appearing on the design decoration film by the secondary pattern of the composite pattern mold may include at least one or more effects among diffraction, interference, dispersion, and polarization effects of light.

2 is a view for explaining the processing method and effect of the secondary pattern formed on the surface of the primary pattern.

The primary pattern has a size of micro or larger, and corresponds to a pattern for the effect of geometric optics, and the secondary pattern formed on the surface of the first pattern has a wave optical effect and may be formed in a size of micro or smaller.

For example, the primary pattern may have an optical structure, and the secondary pattern may have a hologram structure, and may be implemented on the primary pattern through a surface treatment process such as laser, ion beam, plasma, merging, and the like.

In a general method, the effect of a complex pattern using only geometric optics can be obtained, but in the present invention, there is an advantage in that both the effect of a complex pattern of geometric optics and wave optics can be obtained.

3A is a view showing an image 310 of a composite pattern mold on which a primary pattern is formed.

Reference numeral 311 denotes an image by the primary pattern among the composite pattern molds, and reference numeral 312 denotes a cross-section of the primary pattern.

The primary pattern includes patterns in the form of lenticulars, prisms, pyramids, lenses, cones, and holograms.

For example, the lenticular-shaped primary pattern is a pattern having a diffuse reflection effect with respect to light, and may include a plurality of hemispherical concave portions having minute sizes.

In the present invention, it is also possible to use a pattern other than the lenticular pattern as long as the pattern has a diffuse reflection effect on light.

In the lenticular type primary pattern, since the left and right exit lights of the pattern are emitted in a front-diffuse shape, it is possible to emit light having a uniform overall luminance from the front side.

In the present invention, each recess included in the lenticular-shaped primary pattern may be formed on the base layer based on a radius of curvature of 10 μm to 200 μm and a depth of 2 μm to 40 μm. Considering the combination of the lenticular-shaped primary pattern and the prism pattern, the depth of the concave portion is preferably 4 μm to 13 μm.

Also, an interval between the concave portions included in the lenticular-shaped primary pattern may be 20 μm to 100 μm. On the other hand, it is also possible to form protrusions of the embossed pattern instead of the concave portions of the engraved pattern in the lenticular-shaped primary pattern.

In this case, the protrusions may be formed on the substrate based on a radius of curvature of 10 μm to 200 μm and a height of 2 μm to 40 μm.

The prism-shaped primary pattern is a pattern having a mirror reflection effect on light, and may include a plurality of prism-shaped convex portions having a fine size. In the present invention, it is also possible to use a pattern other than the prism pattern as long as it has a mirror reflection effect.

The convex portions provided in the prism-shaped primary pattern are formed in a prism shape. However, the present invention is not limited thereto. For example, the convex portions may be formed in a cone shape or a pyramid shape.

Since the prism-shaped primary pattern controls the refraction of the reflected light by the angle of the incident light and the vertex angle of the convex part, it becomes possible to implement various senses of depth according to the formation of the image (mirror reflection).

In the present invention, the prism pattern can be designed according to the angle adjustment.

Each of the convex portions included in the prism-shaped primary pattern may be formed based on an apex angle of 30 degrees to 160 degrees. In consideration of optimization of the specular reflection characteristics of the prism-shaped primary pattern, it is preferable that the vertex angle of the convex portion is 70 degrees to 150 degrees.

In addition, the convex portions may be formed on the base layer to have a pitch of 10 μm to 100 μm and a height of 2 μm to 30 μm depending on the condition of the vertex angle.

The convex portion of the prism-shaped primary pattern may have an isosceles triangle in cross-section. However, in the present invention, the cross-sectional shape of the convex portion is not limited thereto.

For example, the shape of the convex portion may be formed in an isosceles triangle as well as design changes in various shapes.

3B is a view showing an image of a composite pattern mold in which a secondary pattern is formed on a primary pattern.

Reference numeral 321 denotes an image of a composite pattern mold formed from the first pattern to the second pattern among the composite pattern molds, and reference numeral 322 is a diagram showing a cross section of the reference numeral 321 .

In the primary pattern mold with optical effects such as prism, lenticular, pyramid, cone, and lens, a secondary pattern is formed on the primary pattern mold pattern by laser, ion beam, plasma, sand blasting, merging, etc. A composite pattern mold such as can be formed.

The cross section of reference numeral 321 does not repeat a uniform yaw and pitch as in the cross section of reference numeral 312, but shows a pattern of less than a micro micrometer that is uniform between the uniform yaw and pitch.

As a result, even if a single UV molding layer is formed by using a compound pattern mold as shown in reference numeral 321, a double complex pattern effect can be realized, and the poor visibility of the primary pattern mold can be improved, thereby improving productivity. For example, if a hologram pattern is engraved as a secondary pattern on the optical effect of the primary pattern mold, the interference effect of light can be maximized, thereby increasing the commerciality of the design deco film.

3C is a view for explaining the microstructure of the composite pattern.

An image of reference numeral 330 shows a microstructure 331 of a complex pattern. The microstructure 331 of the composite pattern indicates a structure in which a hologram composite pattern is formed on a prism pattern corresponding to the primary pattern.

Reference numeral 342 denotes a secondary pattern, and denotes a simulation and a result of the haze pattern.

Reference numeral 343 denotes a composite pattern obtained by merging the primary pattern and the secondary pattern, and indicates simulations and results for the trapezoidal pattern and the haze pattern.

The deposition layer is for reflecting light incident on the design decoration film, and may be formed in the design decoration film through a deposition process such as a metalizing technique.

The printed layer is positioned under the deposition layer, and may be formed in the design decoration film according to a specific printing technique in the form of a film. This printed layer may be formed for shielding or no conductive.

After all, if the present invention is used, as a design deco having a complex pattern effect and a manufacturing method thereof, a laser, ion beam, plasma, sand blast, etc. In this way, a design decoration film having a complex pattern effect can be produced by forming a secondary pattern on the primary pattern mold pattern.
