[0026] [First Embodiment]

[0027] Please see Figure 1 As shown, the first embodiment of the present invention provides an artificial leather E1, and in particular an artificial leather E1 with light transmittance, which can be applied to a display device or a touch display device and can exhibit a balance of light transmittance and shielding.

[0028] The artificial leather E1 includes a first light-transmitting resin layer 1, a second light-transmitting resin layer 2, and a fabric light-transmitting resin layer 3. The second light-transmitting resin layer 2 is formed on one side surface of the first light-transmitting resin layer 1, and the fabric light-transmitting resin layer 3 is formed on the side surface of the second light-transmitting resin layer 2 away from the first light-transmitting resin layer 1.

[0029] The first light-transmitting resin layer 1 is a dark-colored light-transmitting resin layer and has a first visible light transmittance. The first visible light transmittance is between 2% and 50%, and optionally between 2% and 30%, but the present invention is not limited thereto.

[0030] The second light-transmitting resin layer 2 is a light-colored light-transmitting resin layer or a colorless (uncolored) light-transmitting resin layer. The second light-transmitting resin layer 2 may be a light-colored light-transmitting resin layer. The second light-transmitting resin layer 2 has a second visible light transmittance.

[0031] The second visible light transmittance of the second light-transmitting resin layer 2 is greater than the first visible light transmittance of the first light-transmitting resin layer 1. The second visible light transmittance is between 30% and 70%, and optionally between 30% and 65%. Furthermore, the difference between the second visible light transmittance of the second light-transmitting resin layer 2 and the first visible light transmittance of the first light-transmitting resin layer 1 can be, for example, between 10% and 50%, and optionally between 20% and 40%. However, the present invention is not limited to the aforementioned difference in transmittance.

[0032] In other words, the first light-transmitting resin layer 1 and the second light-transmitting resin layer 2 together form a light-transmitting resin stack layer with a color that gradually changes from dark to light (or from dark to pale) and a light transmittance that gradually changes from low to high.

[0033] Furthermore, the first light-transmitting resin layer 1 (the dark-colored light-transmitting resin layer) is formed of polyvinyl chloride (PVC) resin, polyurethane resin (PU), thermoplastic polyurethane (TPU), thermoplastic polyolefin elastomer (TPO), or a copolymer resin thereof (such as a copolymer resin of polyvinyl chloride or a copolymer resin of polyurethane). Optionally, the first light-transmitting resin layer 1 is formed of polyvinyl chloride resin or a copolymer resin thereof, and therefore can be defined as a polyvinyl chloride (PVC) resin layer.

[0034] Furthermore, the second light-transmitting resin layer 2 (i.e., the light-colored light-transmitting resin layer) is formed of polyvinyl chloride (PVC) resin, polyurethane resin (PU), thermoplastic polyurethane (TPU), thermoplastic polyolefin elastomer (TPO), or their copolymer resins (such as copolymer resins of polyvinyl chloride or polyurethane). Optionally, the second light-transmitting resin layer 2 is formed of polyvinyl chloride resin or its copolymer resin, and therefore can also be defined as a polyvinyl chloride (PVC) resin layer.

[0035] The first light-transmitting resin layer 1 contains a dye (colorant), and the second light-transmitting resin layer 2 also contains a dye (colorant). The amount of dye added to the first light-transmitting resin layer 1 is greater than the amount of dye added to the second light-transmitting resin layer 2 (or, the dye color of the first light-transmitting resin layer 1 is darker than the dye color of the second light-transmitting resin layer 2). Therefore, the first light-transmitting resin layer 1 has a darker or darker color and is a dark-colored light-transmitting resin layer, and has a lower first visible light transmittance (e.g., 2% to 50%).

[0036] The second light-transmitting resin layer 2 is a light-colored or pale light-colored light-transmitting resin layer, and has a high second visible light transmittance (e.g., 30% to 70%). It should be noted that the types and amounts of dyes (colorants) added to the first light-transmitting resin layer 1 and the second light-transmitting resin layer 2 can be varied according to the requirements of visible light transmittance and color presentation; this invention does not impose any limitations on these variations.

[0037] The fabric's light-transmitting resin layer 3 is a colorless (uncolored) light-transmitting resin layer and has a third visible light transmittance. The third visible light transmittance of the fabric's light-transmitting resin layer 3 is greater than the first visible light transmittance of the first light-transmitting resin layer 1. The third visible light transmittance is between 50% and 90%, and optionally between 65% and 90%.

[0038] In this embodiment, the third visible light transmittance of the fabric light-transmitting resin layer 3 can be selected to be greater than the second visible light transmittance of the second light-transmitting resin layer 2, and the difference between the third visible light transmittance and the second visible light transmittance can be, for example, 10% to 30%, but the present invention is not limited thereto.

[0039] In this embodiment, the surface of the translucent resin layer 3 of the fabric away from the second translucent resin layer 2 has an embossed structure 31, and the embossed structure 31 is formed by a plurality of raised peaks 31a and a plurality of recessed valleys 31b arranged alternately to provide the leather feel required for artificial leather.

[0040] Furthermore, the light-transmitting resin layer 3 of the fabric (a colorless light-transmitting resin layer) is formed of polyvinyl chloride (PVC) resin, polyurethane resin (PU), thermoplastic polyurethane (TPU), thermoplastic polyolefin elastomer (TPO), or their copolymer resins. The light-transmitting resin layer 3 of the fabric may be formed of polyurethane resin (PU), and therefore it can be defined as a polyurethane resin (PU) layer.

[0041] In some embodiments of the present invention, the light-transmitting resin layer 3 of the fabric is formed of: polycarbonate-type polyurethane resin, polyester-type polyurethane resin, polyether-type polyurethane resin, thermoplastic polyurethane (TPU), or a mixture of the above resins.

[0042] Optionally, the light-transmitting resin layer 3 of the fabric is formed of polycarbonate-type polyurethane resin. Therefore, the light-transmitting resin layer 3 of the fabric can have high modulus and high abrasion resistance.

[0043] Furthermore, the first light-transmitting resin layer 1 has a first thickness T1, which is between 10 micrometers and 300 micrometers, optionally between 50 micrometers and 200 micrometers, and particularly preferably between 100 micrometers and 150 micrometers.

[0044] The second light-transmitting resin layer 2 has a second thickness T2, which is between 10 micrometers and 150 micrometers, optionally between 60 micrometers and 130 micrometers, and particularly preferably between 80 micrometers and 100 micrometers. In this embodiment, the second thickness T2 may be less than the first thickness T1, but the present invention is not limited thereto.

[0045] The light-transmitting resin layer 3 of the fabric has a third thickness T3 (that is, the distance from the peak 31a to the bottom surface of the resin layer 3). The third thickness T3 is less than the second thickness T2. The third thickness T3 is between 10 micrometers and 150 micrometers, optionally between 20 micrometers and 40 micrometers, and optionally between 25 micrometers and 35 micrometers.

[0046] Overall, the sum of the thicknesses of the first thickness T1, the second thickness T2, and the third thickness T3 is not less than 30 micrometers and not more than 600 micrometers, and optionally not less than 120 micrometers and not more than 280 micrometers, but the present invention is not limited thereto.

[0047] It is worth mentioning that, in some embodiments of the present invention, the first light-transmitting resin layer 1 and the second light-transmitting resin layer 2 may, for example, be identical to each other or independently exhibit black, gray, brown, red, orange, yellow, green, blue, indigo, purple, or other derived colors. For example, in this embodiment, the dye (colorant) is a black colorant (such as carbon black), and the amount of dye used in the first light-transmitting resin layer 1 is greater than the amount of dye used in the second light-transmitting resin layer 2. Therefore, the first light-transmitting resin layer 1 is a deep black light-transmitting resin layer, while the second light-transmitting resin layer 2 is a light black light-transmitting resin layer, thereby forming a light-transmitting resin stack layer that gradually changes from deep black to light black and has a light transmittance that gradually increases.

[0048] According to the above configuration, the artificial leather E1 provided in the first embodiment of the present invention has a stack of translucent resin layers with colors varying from dark to light and light transmittance from low to high. This achieves a gradient effect in both color depth and light transmittance, and exhibits a balanced light transmittance and opacity. The artificial leather E1 is constructed by stacking different resin layers such as polyvinyl chloride (PVC) and polyurethane (PU), providing design flexibility, durability, and light transmittance. Each resin layer has a different thickness, thus better balancing light transmittance, opacity, and support strength. The first translucent resin layer 1 is thicker, providing a deeper hue and support effect; the second translucent resin layer 2 is an intermediate layer, providing a lighter hue to create a gradient effect in hue and light transmittance; and the fabric translucent resin layer 3 is thinner, ensuring good transparency and flexibility.

[0049] Meanwhile, the embossed texture of the translucent resin layer 3 of the fabric imitates natural leather, enhancing the tactile feel and visual effect of leather. The artificial leather E1 provided in this embodiment of the invention can be applied, for example, to the screen of a touch display device or other electronic display devices used in semi-transparent coverings.

[0050] It should be noted that the visible light transmittance referred to in this article is tested according to the ASTM D1003 standard, which is specifically used to measure the haze and transmittance of transparent plastic materials. The test process uses a spectrophotometer to determine the light transmittance of the material.

[0051] [Second Embodiment]

[0052] Please see Figure 2 As shown, the second embodiment of the present invention also provides an artificial leather E2, which is largely the same as the first embodiment described above, except that the artificial leather E2 of the second embodiment of the present invention is further recessed and has a plurality of light-transmitting blind holes O.

[0053] The plurality of light-transmitting blind holes O are respectively located on the surface of the first light-transmitting resin layer 1 that is away from the second light-transmitting resin layer 2 (e.g., Figure 2 The first light-transmitting resin layer 1 is recessed inward toward the second light-transmitting resin layer 2, and the plurality of light-transmitting blind holes O are arranged at intervals. In other words, the plurality of light-transmitting blind holes O penetrate the first light-transmitting resin layer 1 and only partially penetrate the second light-transmitting resin layer 2, but do not completely penetrate the second light-transmitting resin layer 2, nor do they extend or overlap with the fabric light-transmitting resin layer 3.

[0054] The aperture D of each of the light-transmitting blind holes O can be, for example, between 5 micrometers and 35 micrometers, optionally between 10 micrometers and 30 micrometers, and particularly preferably between 15 micrometers and 25 micrometers. That is, the aperture D of each of the light-transmitting blind holes O is smaller than the first thickness T1 of the first light-transmitting resin layer 1 and also smaller than the second thickness T2 of the second light-transmitting resin layer 2.

[0055] The spacing P between any two adjacent light-transmitting blind holes O in the plurality of said light-transmitting blind holes O is between 10 micrometers and 40 micrometers, optionally between 10 micrometers and 35 micrometers, and particularly preferably between 15 micrometers and 35 micrometers. Each light-transmitting blind hole O may be formed by laser drilling, but is not limited thereto.

[0056] Furthermore, the distance G between the top of each of the light-transmitting blind holes O and the bottom surface of the light-transmitting resin layer 3 of the fabric is not less than 3 micrometers, optionally not less than 5 micrometers, and optionally not less than 8 micrometers.

[0057] Furthermore, in the second embodiment of the present invention, the artificial leather E2 further defines a first region A1 and a second region A2 adjacent to the first region A1 along a transverse direction.

[0058] In this process, a plurality of light-transmitting blind holes O are located in the first region A1. That is, the portions of the first light-transmitting resin layer 1 and the second light-transmitting resin layer 2 of the artificial leather E2 located in the first region A1 have a plurality of light-transmitting blind holes O, while the portions of the first light-transmitting resin layer 1 and the second light-transmitting resin layer 2 of the artificial leather E2 located in the second region A2 do not have any light-transmitting blind holes O.

[0059] In a second embodiment of the present invention, the first region A1 is defined as a light-transmitting region, while the second region A2 is defined as a shielding region (non-light-transmitting region). The plurality of light-transmitting blind holes O disposed in the first region A1 can locally enhance the light transmittance of the artificial leather E2 located in the first region A1.

[0060] Furthermore, the artificial leather E2 can provide locally enhanced light transmittance through a structural design in which "multiple light-transmitting blind holes O respectively penetrate the first light-transmitting resin layer 1 and only partially penetrate the second light-transmitting resin layer 2, and do not completely penetrate the second light-transmitting resin layer 2", while also providing shielding and support for the leather material. In addition, it can prevent moisture from the external environment from entering the interior of the artificial leather E2, so as to avoid affecting the material life of the artificial leather and also to avoid affecting the reliability of the electronic display device installed inside the artificial leather E2.

[0061] In a second embodiment of the present invention, the portion of the artificial leather E2 located in the first region A1 (transparent region) can be attached to the display screen of an electronic display device, so that the image on the display screen can be displayed through the artificial leather E2. Furthermore, when the display screen is not displaying an image, the artificial leather E2 can obscure the display screen, thereby presenting the visual effect of leather. Additionally, the portion of the artificial leather E2 located in the second region A2 (obscuring region) can be disposed in other areas of the display screen, such as the frame or casing area of ​​the electronic display device, or covering surface areas outside the electronic display device (such as the interior casing of a car). Due to its unique functional differentiation and structural design, the artificial leather E2 with the above design is very suitable for applications requiring a combination of aesthetics and functionality, such as automotive interiors, smart home devices, and other consumer electronics products.

[0062] [Third Embodiment]

[0063] Please see Figure 3As shown, the third embodiment of the present invention also provides an artificial leather E3, which is substantially the same as the artificial leather E2 of the second embodiment described above, except that the artificial leather E3 of the third embodiment further includes a pattern layer 4. The pattern layer 4 is disposed on the surface of the first translucent resin layer 1 away from the second translucent resin layer 2 (e.g., ...). Figure 3 On the bottom surface of the first light-transmitting resin layer 1.

[0064] The pattern layer 4 has a first pattern portion 41 and a second pattern portion 42. The first pattern portion 41 is disposed corresponding to a first region A1, and the second pattern portion 42 is disposed corresponding to a second region A2. The first pattern portion 41 of the pattern layer 4 is a light-transmitting portion, allowing the image displayed on the screen of the electronic display device to pass through. The second pattern portion 42 has a pattern shielding to block areas outside the screen of the electronic display device, and the pattern of the pattern shielding can be presented to the outside through the first light-transmitting resin layer 1, the second light-transmitting resin layer 2, and the fabric light-transmitting resin layer 3.

[0065] In this embodiment, the pattern layer 4 may be, for example, a resin medium layer, and the designed pattern is formed on the resin medium layer by printing ink, thereby forming the first pattern portion 41 and a second pattern portion 42 mentioned above, but the present invention is not limited thereto.

[0066] [Fourth Embodiment]

[0067] Please see Figure 4 As shown, the fourth embodiment of the present invention also provides an artificial leather E4, which is substantially the same as the artificial leather E3 of the third embodiment described above, except that the artificial leather E4 of the fourth embodiment further includes a base fabric layer 5. The base fabric layer 5 is a translucent base fabric layer, and it is disposed on the surface of the pattern layer 4 away from the first translucent resin layer 1. The base fabric layer 5 can provide sufficient support for the artificial leather E4.

[0068] In some embodiments of the present invention, the base fabric layer 5 may be, for example, a polyester fiber base fabric, a nylon base fabric, a polyvinyl alcohol formaldehyde fiber (PVA fiber) base fabric, a polypropylene fiber base fabric, a fiberglass base fabric, or an acrylic fiber base fabric, but the present invention is not limited thereto.

[0069] [Beneficial Effects of the Examples]

[0070] One of the beneficial effects of the present invention is that the translucent artificial leather provided by the present invention can form a translucent resin stack layer with a gradual change in color from dark to light and light transmittance from low to high by means of the technical solution of "a first translucent resin layer, which is a dark-colored translucent resin layer" and "a second translucent resin layer, formed on one side surface of the first translucent resin layer, and the second translucent resin layer is a light-colored translucent resin layer or an uncolored translucent resin layer" and "a fabric translucent resin layer, formed on the side surface of the second translucent resin layer away from the first translucent resin layer, and the side surface of the fabric translucent resin layer away from the second translucent resin layer has an embossed structure". This achieves a gradual change in color depth and light transmittance, and exhibits a balanced translucency and opacity.

[0071] The artificial leather provided in this embodiment of the invention can be applied, for example, to the screen of a touch display device or to other electronic display devices with semi-transparent covers.

[0072] Furthermore, the artificial leather can provide locally enhanced light transmittance through a structural design in which "multiple light-transmitting blind holes penetrate the first light-transmitting resin layer and only partially penetrate the second light-transmitting resin layer, without completely penetrating the second light-transmitting resin layer", while also providing shielding and support for the leather material. In addition, it can prevent moisture from the external environment from entering the interior of the artificial leather, so as to avoid affecting the material life of the artificial leather, and also to avoid affecting the reliability of the electronic display device installed on the inside of the artificial leather.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. All equivalent changes and modifications made in accordance with the claims of the present invention shall fall within the scope of protection of the claims of the present invention.
