Next, description will be given of a garnish 100 according to an embodiment of the present application.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4 together, fig. 1 is a schematic structural diagram of a decoration according to an embodiment of the present application; FIG. 2 is a schematic view of magnetic particles of a decorative film in the decorative piece shown in FIG. 1; FIG. 3 is a schematic illustration of the particle size of the magnetic particles of FIG. 2; fig. 4 is a schematic crown view of the texture in the magnetic particles. The decorative piece 100 includes a substrate 110 and a decorative film 120. The decorative film 120 is supported on the substrate 110, the decorative film 120 includes an ink layer 120a, the ink layer 120a includes a light-transmitting ink base 122 and a plurality of magnetic particles 121 distributed in the ink base 122, wherein the magnetic particles 121 have magnetism, and the magnetic particles 121 have at least one texture 121a, the texture 121a has a plurality of reflective surfaces 121b, and the crown height H of the texture 121a satisfies: h is 1 μm or less and 30 μm or less, and the particle diameter D of the magnetic particles 121 satisfies: d is more than or equal to 10 mu m and is less than or equal to 80 mu m.

The substrate 110 may be a composite board, a film or glass white, a ceramic sheet, or the like. The present embodiment is not limited thereto.

The magnetic particles 121 have magnetism, and thus the decoration 100 may be prepared by a magnetic mold at the time of preparation, and the magnetic particles 121 are attracted by a magnetic force in the magnetic mold to move, thereby forming a preset pattern. It will be appreciated that in other embodiments, the decorative piece 100 is not prepared by a magnetic mold when the decorative piece 100 is prepared, and the magnetic particles 121 in the ink layer 120a of the decorative piece 100 are randomly distributed in the ink base 122. The distribution pattern of the magnetic particles 121 in the ink base 122 is not limited in this embodiment.

In fig. 2, the magnetic particles 121 are illustrated as comprising three texture structures 121a, it being understood that the embodiment of the application should not be construed as being limited. The magnetic particles 121 have at least one texture 121a, and the texture 121a has a plurality of reflective surfaces 121b, so that when light irradiates the texture 121a, the light is reflected by at least one of the reflective surfaces 121b of the texture 121a, thereby exhibiting a certain luster. It can be appreciated that, since the texture structure 121a has a plurality of reflective surfaces 121b, i.e., the texture structure 121a has a three-dimensional (3D) configuration, when light from different angles is irradiated to the texture structure 121a, the reflective surfaces 121b of the texture structure 121a can reflect light, and thus, the glossiness and texture of the decoration 100 are improved. Thus avoiding the defect that the flash cannot be generated under certain angles to present heterochromatic (such as blackening) or dirty points. It will be appreciated that in fig. 2, the light reflecting surface 121b of the origin is marked in one texture 121a, and that the other surface of the texture 121a is also the light reflecting surface 121b.

In this embodiment, the crown height of the texture 121a refers to the height of the texture 121 a. The crown height H of the texture 121a of the decorative piece 100 provided by the embodiment of the present application may be, but is not limited to, 1 μm, or 2 μm, or 3 μm, or 4 μm, or 5 μm, or 6 μm, or 7 μm, or 8 μm, or 9 μm, or 10 μm, or 11 μm, or 12 μm, or 13 μm, or 14 μm, or 15 μm, or 16 μm, or 17 μm, or 18 μm, or 19 μm, or 20 μm, or 21 μm, or 22 μm, or 23 μm, or 24 μm, or 25 μm, or 26 μm, or 27 μm, or 28 μm, or 29 μm, or 30 μm.

In the present embodiment, the particle diameter of the magnetic particles 121 refers to the maximum distance between two points of the magnetic particles 121. The particle diameter D of the magnetic particles 121 may be, but is not limited to, 10 μm, or 15 μm, or 20 μm, or 30 μm, or 35 μm, or 40 μm, or 45 μm, or 50 μm, or 55 μm, or 60 μm, or 65 μm, or 70 μm, or 75 μm, or 80 μm.

The crown height H of the texture 121a satisfies: h is 1 μm or less and 30 μm or less, and the particle diameter D of the magnetic particles 121 satisfies: on the one hand, the texture structure 121a is convenient to prepare a plurality of reflecting surfaces 121b, and when light rays from different angles are irradiated to the texture structure 121a, the reflecting surfaces 121b of the texture structure 121a can reflect the light rays, so that the defects that the light rays cannot flash at certain angles to present different colors or dirty stains are reduced and even avoided, and the decorative piece 100 has better glossiness and texture; on the other hand, the size of the texture structure 121a may be relatively smaller, so that the light reflected by the texture structure 121a is finer and smoother, and the texture is more stereoscopic, thereby further improving the glossiness and texture of the decoration 100.

In summary, in the decoration 100 according to the embodiment of the application, the magnetic particles 121 have at least one texture 121a, and the texture 121a has a plurality of reflective surfaces 121b, so that when light irradiates the texture 121a, the light is reflected by at least one of the reflective surfaces 121b, thereby forming a certain luster. The crown height H of the texture 121a satisfies: h is 1 μm or less and 30 μm or less, and the particle diameter D of the magnetic particles 121 satisfies: on the one hand, the texture structure 121a is convenient to prepare a plurality of reflecting surfaces 121b, and when light rays from different angles are irradiated to the texture structure 121a, the reflecting surfaces 121b of the texture structure 121a can reflect the light rays, so that the defects that different colors (such as black spots) or dirt spots are presented due to no flashing at certain angles are reduced or even avoided, and the luster and texture of the decorative piece 100 are good; on the other hand, the size of the texture structure 121a may be relatively smaller, so that the light reflected by the texture structure 121a is finer and smoother, and the texture is more stereoscopic, thereby further improving the glossiness and texture of the decoration 100. When the decoration 100 is applied to the electronic device 1, the electronic device 1 has a high identification degree.

In one embodiment, the light transmittance Tr of the ink substrate 122 satisfies: the mass ratio WP of the magnetic particles 121 in the ink layer 120a is 60% or less and is as follows: WP is more than or equal to 5% and less than or equal to 30%.

In one embodiment, the optically transmissive ink substrate 122 in the ink layer 120a is transparent or translucent. For example, the light transmittance Tr of the ink substrate 122 satisfies: and Tr is 60% or less. For example, the light transmittance Tr of the ink substrate 122 may be, but is not limited to, 60%, or 65%, or 70%, or 75%, or 80%, or 85%, or 90%, or 95%, etc.

The light transmittance Tr of the ink substrate 122 satisfies: 60% Tr, when light is irradiated to the plurality of magnetic particles 121 in the ink layer 120a, the light reflected by the magnetic particles 121 can be easily observed by human eyes through the ink substrate 122.

The mass fraction WP of the magnetic particles 121 in the ink layer 120a may be, but is not limited to, 5%, or 10%, or 15%, or 20%, or 25%, or 30%.

The mass fraction WP of the magnetic particles 121 in the ink layer 120a satisfies: the WP of 5% or more and 30% or less can make the content of the magnetic particles 121 in the ink layer 120a moderate, so that the garnish 100 has a good glossiness and texture.

In one embodiment, the plurality of magnetic particles 121 form a predetermined pattern; or the plurality of magnetic particles 121 are randomly distributed in the ink substrate 122.

The magnetic particles 121 have magnetism, and thus the decoration 100 can be manufactured by a magnetic mold at the time of manufacturing, and the magnetic particles 121 are attracted to move by the magnetic force of the pattern in the magnetic mold, thereby forming a preset pattern. The preset pattern may be, but is not limited to, a heart shape, a five-pointed star, a brand Logo (Logo), a figure, a landscape painting, etc.

When the light irradiates the decoration 100, the light can be reflected by at least one of the reflective surfaces 121b of the texture structure 121a, so as to present a certain luster, and the texture structure 121a has the reflective surfaces 121b, so that the light with different angles can be reflected, thereby reducing or even avoiding the defect that the decoration 100 cannot flash at certain angles to present different colors or dirty stains, and the glossiness and texture of the decoration 100 are better. When the plurality of magnetic particles 121 in the decoration 100 form a predetermined pattern, light is irradiated to the decoration 100, the predetermined pattern formed by the magnetic particles 121 has a certain gloss and can be observed from various angles, thereby improving the decoration effect of the decoration.

When the plurality of magnetic particles 121 form a predetermined pattern, whether the magnetic particles 121 are present in the other area of the decorative member 100 other than the predetermined pattern area is not limited. In an embodiment, when the plurality of magnetic particles 121 form a predetermined pattern, the decoration 100 does not have the magnetic particles 121 in the other region corresponding to the predetermined pattern region or has the magnetic particles 121, but the magnetic particles 121 in the other region are different in size from the magnetic particles 121 in the predetermined pattern region, so that the light reflecting effect of the magnetic particles 121 in the other region and the light reflecting effect of the magnetic particles 121 in the predetermined pattern region are different.

It will be appreciated that in other embodiments, the decorative piece 100 is not prepared by a magnetic mold when the decorative piece 100 is prepared, and the magnetic particles 121 in the ink layer 120a of the decorative piece 100 are randomly distributed in the ink base 122. The distribution pattern of the magnetic particles 121 in the ink base 122 is not limited in this embodiment.

Compared to the ink film layer having only the ink base 122 and no magnetic particles 121, the decoration 100 according to the embodiment of the present application, when the magnetic particles 121 are randomly distributed in the ink base 122, the magnetic particles 121 reflect light, so that the ink layer 120a may have a certain gloss, for example, a pearlescent effect.

Referring to fig. 2 and fig. 5 together, fig. 5 is a schematic diagram of a magnetic particle according to another embodiment. The magnetic particles 121 comprise one or a plurality of texture structures 121a arranged periodically.

In fig. 2, the magnetic particles 121 comprise 3 textures 121a arranged periodically, and in fig. 5, the magnetic particles 121 comprise one texture 121a; it will be appreciated that the number of the texture structures 121a in fig. 2 and 5 is only one illustration and should not be construed as limiting the magnetic particles 121 of the embodiments of the present application.

The decoration 100 according to the embodiment of the present application includes one or a plurality of texture structures 121a arranged periodically, so that the texture may have more reflective surfaces 121b. When light from different angles is irradiated to the texture structure 121a, the reflective surface 121b of the texture structure 121a can reflect light, so that the defect that the decorative piece 100 cannot flash at certain angles to present abnormal color or dirty stains is reduced and even avoided, and the glossiness and texture of the decorative piece 100 are good.

Referring to fig. 6, fig. 6 is a schematic diagram of a magnetic particle according to another embodiment. In order to clearly illustrate the structure of the magnetic layer 1212, fig. 6 (a) illustrates a three-layer magnetic layer 1212 stacked; fig. 6 (b) is a schematic diagram showing separation of the three magnetic layers 1212 in fig. 6 (a). The magnetic particles 121 include a plurality of magnetic layers 1212 stacked in a predetermined direction.

It will be appreciated that the number of magnetic layers 1212 included in the magnetic particles 121 illustrated in fig. 6, as well as the specific structure of the magnetic layers 1212, should not be construed as limiting embodiments of the present application. In other embodiments, the number of magnetic layers 1212 may be other numbers of layers, such as 2 layers, 10 layers, 15 layers, 20 layers, etc. Accordingly, in other embodiments, the magnetic layer 1212 may have other structures, and the other structures of the magnetic layer 1212 will be described in detail later.

When the magnetic particles 121 include a plurality of magnetic layers 1212 stacked in a predetermined direction, the magnetic particles 121 may have better magnetic properties. If the decoration 100 is made of a magnetic mold, when the magnetic particles 121 form a predetermined pattern, the magnetic particles 121 can be better attracted to the magnetic force in the magnetic mold to move, so that the quality of the predetermined pattern formed is higher. It will be appreciated that the magnetic particles 121 comprise a plurality of magnetic layers 1212 stacked in a predetermined direction, and are also applicable to embodiments in which the plurality of magnetic particles 121 are randomly distributed in the ink base 122.

Referring to fig. 6 and fig. 7 together, fig. 7 is a schematic structural diagram of the magnetic layer in fig. 6 according to an embodiment. The magnetic layer 1212 includes a first sub-magnetic layer 12122, a second sub-magnetic layer 12123, and a third sub-magnetic layer 12124 stacked in a predetermined direction, the first sub-magnetic layer 12122 having a melting point higher than that of the second sub-magnetic layer 12123, and the third sub-magnetic layer 12124 having a melting point higher than that of the second sub-magnetic layer 12123.

The melting point of the first sub-magnetic layer 12122 is higher than that of the second sub-magnetic layer 12123, and the first sub-magnetic layer 12122 is more stable than the second sub-magnetic layer 12123 at high temperature; accordingly, the melting point of the third sub-magnetic layer 12124 is higher than that of the second sub-magnetic layer 12123, and the third sub-magnetic layer 12124 is more stable than the second sub-magnetic layer 12123 at high temperature. Therefore, the magnetic layer 1212 includes a first sub-magnetic layer 12122, a second sub-magnetic layer 12123, and a third sub-magnetic layer 12124 stacked in a predetermined direction, the first sub-magnetic layer 12122 has a melting point higher than that of the second sub-magnetic layer 12123, and the third sub-magnetic layer 12124 has a melting point higher than that of the second sub-magnetic layer 12123, so that the magnetic layer 1212 has a relatively stable characteristic.

Further, in one embodiment, the second sub-magnetic layer 12123 has a magnetic property that is greater than the magnetic property of the first sub-magnetic layer 12122, and the second sub-magnetic layer 12123 has a magnetic property that is greater than the magnetic property of the third sub-magnetic layer 12124. Therefore, the magnetic layer 1212 has not only better stability but also higher magnetic properties.

Referring to fig. 8, fig. 8 is a schematic structural diagram of a magnetic layer according to an embodiment. The magnetic layer 1212 includes a first sub-magnetic layer 12122, a second sub-magnetic layer 12123, and a third sub-magnetic layer 12124 stacked in a predetermined direction, the first sub-magnetic layer 12122 having a melting point higher than that of the second sub-magnetic layer 12123, and the third sub-magnetic layer 12124 having a melting point higher than that of the second sub-magnetic layer 12123.

Further, in the present embodiment, the magnetic layer 1212 further includes a first sub-under color layer 12121 and a second sub-under color layer 12125.

The second sub-under color layer 12125 is disposed on a side of the third sub-magnetic layer 12124 facing away from the second sub-magnetic layer 12123.

The first sub-under color layer 12121 has a color, for example, the first sub-under color layer 12121 is silver or gold, etc. For example, when the first sub-primer layer 12121 is silver, the first sub-primer layer 12121 may be an aluminum layer or a silver layer.

The first sub-under color layer 12121 is disposed on a side of the first sub-magnetic layer 12122 facing away from the second sub-magnetic layer 12123, so that when the magnetic particles 121 are viewed from the side of the first sub-under color layer 12121, the color of the first sub-under color layer 12121 is visible, that is, the magnetic layer 1212 can represent the color of the first sub-under color layer 12121, so that the decoration 100 has a better decorative effect.

The second sub-under color layer 12125 has a color, for example, the second sub-under color layer 12125 is silver or gold, etc. For example, when the second sub-primer layer 12125 is silver, the second sub-primer layer 12125 may be an aluminum layer or a silver layer. It is to be understood that the color of the second sub-primer layer 12125 may be the same as or different from the color of the first sub-primer layer 12121, which is not limited herein.

The second sub-under color layer 12125 is disposed on a side of the third sub-magnetic layer 12124 facing away from the second sub-magnetic layer 12123, so that when the magnetic particles 121 are viewed from the second sub-under color layer 12125, the color of the second sub-under color layer 12125 can be observed, that is, the magnetic layer 1212 can display the color of the second sub-under color layer 12125, so that the decoration 100 has a better decorative effect.

When light is irradiated to the first dielectric layer 1211, the first dielectric layer 1211 may reflect and refract the light, thereby forming a color. The film structure, film material, thickness, etc. of the first dielectric layer 1211 may affect the color of the light irradiated to the first dielectric layer 1211.
