To facilitate the understanding of the present application, the application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terms used in the specification of the present application herein is only for the purpose of describing specific embodiments, and is not intended to limit the present application. The term “and/or” as used herein includes any and all combinations of one or more related listed items.
The present application discloses a decorative sheet, including a supporting layer and a solid film layer. The solid film layer is disposed on the supporting layer and presents a color. The solid film layer includes a single layer or a composite layer. A thickness and/or material of at least one layer in the solid film layer is set to be varied. In the decorative sheet of the present application, through the change of the thickness and/or material of the solid film layer, the color of the solid film layer can be changed, including shade changes, color changes and other variety changes, so that the decorative sheet has rich color, rich vision, better decoration effect and higher recognition.
In an embodiment, the thickness of at least one layer in the solid film layer varies gradually, regularly or randomly. In a single layer, the color of a same material at different thicknesses is different. Different changes of the thickness achieve the change of the color, and a preset color is obtained finally with the color of other layers. A change of the thickness may be a gradual change in one or more directions, a change in a preset rule or a random change, to obtain a gradation color, a regularly changed color, or a random color. A change of color includes a change in color depth (for example, gradually changing from light pink to darker) and a change in color type (for example, changing from red to blue).
In an embodiment, the solid film layer includes a plurality of film layers stacked, and the plurality of film layers are combined to form the solid film layer. Preferably, the solid film layer includes 5-8 film layers. For example, the solid film layer includes 5 film layers, namely Si layer, Ti layer, Si layer, Ti layer, Si layer, which are sequentially plated on one side of the supporting layer. The Si layer here refers to a film layer mainly containing Si, such as a SiO2 layer, referred to as Si layer for short; the Ti layer here refers to a film layer mainly containing Ti, such as a Ti3O5 layer, referred to as Ti layer for short; the same below.
In an embodiment, a thickness of one of the plurality of film layers is set to be varied gradually in one direction. The thickness of at least one film layer is set to be varied gradually. The color of an area with a gradual thickness presents a gradual change, which may be a gradual change of shade or a gradual transition from one color to the other.
In an embodiment, a thickness of one of the plurality of film layers gradually thins, gradually thickens, first thins and then thickens, first thickens and then thins, alternates between thinning and thickening, gradually thins and then gradually thickens or gradually thickens and then gradually thins from one side to the other side. For example, the thickness of the Si layer closest to the supporting layer, among the above mentioned solid film layer with 5 film layers, gradually becomes thicker from one side to the other.
In an embodiment, a thickness of each of the plurality of film layers is set to be varied gradually, or be varied gradually in one direction with a same or different tendency. Taking the above 5 layers as an example, the thickness of each layer may thin gradually from the left to the right, or one layer may thin from the left to the right, while the adjacent layer thins from the right to the left.
In an embodiment, thicknesses of two adjacent film layers in the plurality of film layers are set to be complementary.
In an embodiment, one side surface of one of the plurality of film layers is an undulating or curved surface. That is, one side surface of the film layer is not a flat surface, which causes the thickness of the film layer to change, thereby realizing a variety of colors.
In an embodiment, the materials of at least two regions of at least one layer in the solid film layer are different. The difference in materials means that materials forming different regions of the film layer are different. The difference in materials refers to difference in content, type, specific gravity, and the like.
In an embodiment, the solid film layer includes one or a plurality of film layers, one of the film layers includes a first region with a first material, a second region with a second material, and a third region with the first material and the second material mixed. The first region presents a color, the second region presents another color, and the third region presents a transitional color, a mixed color, or a third color. Cooperating with other film layers, the gradual change and type change of the color are realized.
In an embodiment, the solid film layer includes a plurality of film layers, at least two of the plurality of film layers have the first region, the second region and the third region, respectively. The first region, the second region, and the third region of the at least two of the plurality of film layers are disposed in identical, partially identical, or completely different positions. The position distribution or size of each region is the same or different. The color presented by the solid film layer is richer.
In an embodiment, the solid film layer is a composite layer, the solid film layer includes a plurality of partitions and a junction region between adjacent partitions in the plurality of partitions, and a material of at least one layer of the plurality of partitions is different. With the material change of one or more layers, the color change of the solid film layer is realized.
The decorative sheet of the present application realizes the color change through the change setting of the solid film layer. Specifically, the change of the thickness and/or the change of the material of the solid film layer may be only the change of the thickness, or only the change of the material, or double changes of the material and the thickness, or the change of thickness in one part and the change of material in the other part. Therefore, the solid film layer can realize colorful changes, to have a better decorative effect, and a higher degree of recognition.
In an embodiment, the solid film layer is an evaporative plating layer, a sputtering plating layer, an electroless plating layer or an electroplating layer. In other embodiments, the solid film layer may also be formed by printing, screen printing, and the like.
In an embodiment, the supporting layer is a PET layer, a PMMA layer, a PC layer, a glass layer, an organic glass layer, a PI layer or a PMMA composite layer. The supporting layer may be a single layer or a composite layer and it may be transparent and colorless, transparent and colored, or opaque.
In an embodiment, the solid film layer is a composite layer with a plurality of layers, and is disposed on both sides of the supporting layer.
The present application also discloses a cover plate for a consumer electronic product, which includes the decorative sheet described above. For example, a back cover of a mobile phone with the above-mentioned decorative sheet can present changing colors, so that the decoration effect is excellent, and the recognition degree is high.
Hereinafter, the decorative sheet is described with examples with reference to the figure.
