Description
TECHNICAL FIELD
[0001] The utility model belongs to printing technical field, and specifically is a color gold stamping film for thermal transfer printing. BACKGROUND
[0002] Gold stamping film, the bright pearl in the decoration field, also known as anodized aluminum, through the unique stamping process, the shining metal foil and diversified substrate are closely combined, and the printing material is endowed with incomparable metal luster or brilliant color effect. The core of this process is hot pressing transfer technology, that is, under the joint action of high temperature and accurate pressure, the metal foil or color metal foil layer is accurately transferred to the surface of the printing material, forming exquisite patterns or characters, and adding a bright and eye-catching luxury to the product.
[0003] However, the existing gold stamping film structure, although it has realized efficient stamping effect through the precise combination of base film, separation layer, color layer, aluminum plating layer and adhesive layer, still exposes some problems in actual application. In particular, the combination mode between the separation layer and the color layer becomes the key factor affecting the performance of the gold stamping film. In the existing five-layer structure, the separation layer and the color layer are closely combined, but there is lack of additional material or treatment between the two to enhance the bonding force and peeling performance. Although this design meets the basic stamping requirements to some extent, it often appears to be inadequate when facing complex and changeable printing material and stamping conditions.
[0004] Specifically, insufficient bonding force may cause peeling between the separation layer and the color layer during the stamping process, affecting the integrity and clarity of the stamped pattern. Poor peeling performance may make the gold stamping film have too strong adhesion on the printing material, which is difficult to peel off easily when needed, causing inconvenience to subsequent processing and use.
