Description

Technical Field

[0001] This utility model relates to the technical field of film-free labels, and in particular to a three-dimensional hot stamping silver-painted film-free label. Background Technology

[0002] In fields such as baseball bats, automobiles, electric vehicles, bicycles, sporting equipment, bags, and decorative panels, 3D hot stamping and color-painted logos are key components for enhancing product appearance and brand recognition, and their performance and effects directly affect the product's market competitiveness. As the consumer market's demands for more refined and personalized product appearances continue to rise, existing hot stamping and color-painting technologies are gradually becoming insufficient to meet practical application needs.

[0003] While traditional hot stamping labels can enhance visual appeal through metallic texture, their manufacturing process limits the ability to achieve subtle, natural gradients of two or more colors on the hot stamping layer. This results in limited color expression and makes it difficult to meet the customized needs of complex designs. Ordinary painted labels, while capable of multi-color printing, lack the fusion of metallic luster and sufficient three-dimensionality, failing to convey a clear sense of raised depth through visual and tactile feedback.

[0004] To achieve a three-dimensional effect, some existing solutions use multiple layers of paint to create the raised structure, but this process has significant drawbacks: On the one hand, repeated painting can lead to unstable adhesion between coatings, easy collapse of three-dimensional structures, and low yield of finished products; on the other hand, excessive use of paint not only increases production costs but also has the problem of insufficient environmental protection, which is contrary to the current trend of green manufacturing.

[0005] Meanwhile, in existing technologies, processes such as hot stamping, painting, and 3D molding are often independent of each other and lack effective synergy and integration, which can easily lead to separation, rejection, or chemical reactions between the processes, further affecting the stability and service life of the product.

[0006] Therefore, there is an urgent need for a signage product that can simultaneously achieve the metallic texture of hot stamping, delicate color gradients, and a strong three-dimensional effect, in order to meet the comprehensive requirements of appearance appeal, tactile experience, and process stability. However, existing technologies have not yet provided an effective solution.

[0007] In view of this, the inventor has specially designed a three-dimensional hot stamping silver-painted label without film, which is the basis of this invention. Utility Model Content

[0008] To solve the above problems, the technical solution of this utility model is as follows: A three-dimensional hot stamping and color-painted label without film includes: Transfer layer; A base coat is disposed on the transfer layer and does not exceed the range of the transfer layer; An anti-repellent gold oil layer is provided to completely cover the base oil layer and not exceed the area of ​​the transfer layer; A hot stamping silver base coat is applied over the anti-repellent gold paint layer but does not extend beyond the area of ​​the anti-repellent gold paint layer.

A protective gold varnish layer is applied to the gold varnish layer and its extent is consistent with that of the gold varnish layer. The centerline layer is positioned on the protective gold varnish layer and extends beyond the protective gold varnish layer. The hot-stamping layer is used to present a metallic texture, the painted layer is used to achieve color gradient, and the central edge layer is used to construct a three-dimensional raised structure.

[0009] Preferably, the centerline layer is further provided with a tearable film layer.

[0010] Preferably, the peelable film layer completely covers the centerline layer and does not exceed the range of the transfer layer.

[0011] Preferably, the surface of the tearable film layer is further provided with a release paper layer, which extends beyond the tearable film layer.

The following provides a detailed description of the material selection, molding process, and range control for each layer: 1. Materials and molding processes at each level (1) Transfer layer Material selection: Use transfer paper with a release treatment on the surface, with a basis weight of 80-120g / ㎡ (preferably 100g / ㎡), and use a silicone-based release agent to ensure smooth separation from the base coat during subsequent transfer.

[0021] Function: As the basic carrier of the entire logo, it carries all the upper functional layers and achieves the interlayer peeling in the transfer process through release molding.

[0022] (2) Bottom oil layer Material selection: Use acrylic base oil with a solid content of 30-40% and a viscosity of 20-30s (Ford Cup 4, 25℃).

[0023] Molding process: The coating is applied to the upper surface of the transfer layer by roller coating, with the coating amount controlled at 5-8g / ㎡ (dry weight), and then cured by baking in an 80℃ oven for 10-15 minutes.

[0024] Range control: The coating area shall not exceed the edge of the transfer layer, and the alignment error with the edge of the transfer layer shall be ≤0.1mm by mold positioning.

[0025] (3) Anti-repellent gold oil layer Material selection: Anti-repellent gold oil-Ti layer (containing titanium modified resin) is used, and the surface tension is controlled at 32-35 dyne (tested by a tension meter).

[0026] Molding process: The base coat is completely covered by screen printing (80-100 mesh screen), and dried at 60℃ for 5-8 minutes after printing to ensure a tight bond with the base coat.

[0027] Scope control: The printing area should not exceed the edge of the transfer layer and should completely cover the base coat (coverage area ≥99%) to avoid interlayer rejection caused by local exposure.

[0028] (4) Hot stamping silver base oil layer Material selection: Use a thermosetting base oil specifically for hot stamping, with a Tg value (glass transition temperature) of 50-60℃ and a compatibility of ≥95% with the hot stamping foil.

[0029] Molding process: Apply the coating to the anti-repellent gold oil layer by screen printing (100-120 mesh screen), with a coating amount of 8-12g / ㎡ (dry weight), and bake at 100℃ for 8-10 minutes to cure.

[0030] Range control: The printing area shall not exceed the edge of the anti-repellent gold paint layer, and the alignment error with the anti-repellent gold paint layer shall be ≤0.05mm to ensure the stable adhesion of the hot stamping layer.

[0031] (5) Hot stamping layer Material selection: Aluminum foil-based hot stamping foil (thickness 12-15μm) with a gloss level ≥90% (tested at a 60° angle).

[0032] Molding process: The hot stamping foil is transferred to the surface of the hot stamping base layer using a hot stamping machine (pressure 3-5 bar, temperature 120-140℃, speed 10-15 m / min) to achieve a metallic texture.

[0033] Range control: The transfer area is completely consistent with the hot stamping base layer (deviation ≤0.05mm) to ensure no missed or overflowing.

[0034] (6) Coating with gold oil layer Material selection: Transparent solvent-based gold oil, hardness ≥2H (tested with a pencil hardness tester), alcohol resistance ≥50 wiping cycles (95% alcohol, 500g force).

[0035] Molding process: The hot stamping layer and the base coat of hot stamping are completely covered by screen printing (80-100 mesh screen), with a printing amount of 10-15g / ㎡ (dry weight), and dried at 70℃ for 10-15min.

[0036] Range control: The printing range extends 0.5-1mm beyond the edge of the anti-repellent gold paint layer, but does not exceed the range of the peelable film layer, forming a complete protection for the hot stamping silver layer and preventing subsequent ink erosion of the color painting layer.

[0037] (7) Painted layer Material selection: UV-curable colored inks (yellow, magenta, cyan, black or spot colors), fineness ≤5μm, adhesion ≥4B (cross-cut adhesion test).

[0038] Molding process: Color gradient is achieved on the coated gold varnish layer by multi-color screen printing (120-150 mesh screen, adjusted according to the fineness of the pattern). Each color is cured by UV lamp (energy 80-100mJ / cm²) after printing, and the overprinting accuracy is ≤0.03mm.

[0039] Range control: The printing area should not exceed the edge of the gold coating layer to ensure that the color pattern is fully covered by the gold coating layer.

[0040] (8) Painted gold varnish layer Material selection: High-gloss UV gold oil, gloss ≥95% (tested at 60° angle), thickness 3-5μm after curing.

[0041] Molding process: Screen printing (100-120 mesh screen) on the color layer, with the printing area extending 0.3-0.5mm beyond the edge of the color layer, followed by UV curing (energy 100-120mJ / cm²).

[0042] Function: Protects the color of the painted layer, enhances the surface gloss, and provides an adhesion base for the protective gold varnish layer.

[0043] (9) Painted protective gold coating Material selection: Abrasion-resistant UV gold oil, abrasion resistance ≥500 times (Taber abrasion tester, 500g load), weather resistance ≥1000h (QUV test, no obvious discoloration).

[0044] Molding process: Screen printing (80-100 mesh screen) on the gold varnish layer, with the same area as the gold varnish layer, UV curing (energy 120-150mJ / cm²), thickness 5-8μm.

[0045] Function: To enhance the protection of the painted layer and resist wear, corrosion and UV aging.

[0046] (10) Centerline layer Material selection: 3D UV ink, hardness ≥ HB after curing, and adjustable raised height (0.1-0.3mm).

[0047] Molding process: Thick screen printing (60-80 mesh screen) is applied to the protective gold varnish layer. Depending on the 3D effect requirements, 1-3 layers of printing are applied. After each printing, UV curing (energy 150-200mJ / cm²) is performed to finally form a raised structure.

[0048] Range control: The printing range extends 0.5-1mm beyond the edge of the protective gold varnish layer. The accuracy of the raised structure is ensured by positioning the mold.

[0049] (11) Tearable film layer Material selection: PET tearable film (thickness 25-30μm), surface coated with pressure-sensitive adhesive (initial tack ≥ 10# steel ball).

[0050] Molding process: The peelable film layer is completely covered on the center line layer by a laminating machine with a lamination pressure of 0.2-0.3MPa to ensure no air bubbles.

[0051] Range control: The bonding range does not exceed the edge of the transfer layer, and the alignment error with the transfer layer is ≤0.1mm.

[0052] (12) Release paper layer Material selection: silicone paper (thickness 60-80μm), release force 5-10g / in (180° peel test).

[0053] Forming process: The tearable film is applied manually or mechanically to the surface of the label, extending 1-2 mm beyond the edge of the tearable film to protect the entire label.

[0054] 2. Transfer Application Process When it is necessary to transfer the film-free label of this utility model onto a target substrate (such as a baseball bat or automotive parts surface), the operation steps are as follows: Peel off the release paper layer to expose the tear-off film layer; The peelable film layer, together with the underlying functional layers (centerline layer to base oil layer), is bonded to the surface of the target substrate, and a pressure of 0.3-0.5 MPa is applied to ensure a tight bond. After peeling off the transfer layer, the base coat adheres to the surface of the target substrate, while the remaining functional layers (from the anti-repellent gold coating to the centerline layer) remain on the substrate surface. Finally, the peelable film layer is peeled off to complete the transfer, ultimately forming a composite logo effect of "hot stamping + color painting + three-dimensional" on the substrate surface.

[0055] 3. Performance Verification The performance of the 3D hot stamping silver-painted label without film in this embodiment has been verified through the following tests: Cross-cut test: According to GB / T9286-1998 standard, a 1mm grid is drawn, and after peeling 3M tape 180°, there is no peeling between layers (reaching level 5B). Alcohol resistance test: The surface is rubbed 50 times with a force of 500g using a cotton cloth soaked in 95% alcohol. There is no exposure of the base material or discoloration, and the gloss is retained at ≥90%. 3D effect test: The center line layer has a raised height of 0.15mm, with a clear tactile feel and obvious visual 3D effect; Weather resistance test: After 1000 hours of QUV testing, there was no yellowing or cracking, and the color deviation ΔE ≤ 2.

[0056] This embodiment seamlessly integrates three core effects—metallic luster, delicate colors, and 3D tactile feel—through a layered design consisting of a hot stamping layer (metallic texture), a painted layer (color gradient), and a center line layer (three-dimensional raised). This breaks through the limitations of traditional single-effect logos, meets the consumer market's demand for refined and personalized product appearance, and significantly enhances the brand recognition and market competitiveness of the attached objects (such as baseball bats, car parts, etc.).
