Three-dimensional (3D) texture transfer printing film and method for preparing same

Abstract

The invention relates to a three-dimensional (3D) texture transfer printing film and a method for preparing the same. The three-dimensional (3D) texture transfer printing film includes a carrier layer having a first texture on one face, a glue layer which is disposed on the face where the carrier layer having the first texture and has a second texture in a position corresponding to the position of the first texture, and a bonding layer which is disposed on one face of the glue layer. The first texture is directly forme don the carrier layer rather than another hardened layer. No release layer is arranged between the first texture and the second texture. Lines of the second texture are obvious and deep. Therefore, user demands of rapid processing, low cost, etc. are met.

Description

technical field [0001] The invention relates to a 3D texture transfer printing film and a preparation method thereof, which can make the transferred texture more obvious or deep, and can reduce the film preparation process and materials. Background technique [0002] In recent years, 3C products have been widely used in people's daily life, such as mobile phones, notebook computers, tablet computers or handheld electronic products. Although these electronic products bring people's life considerable convenience, the shells of such electronic products It is relatively monotonous, so all major manufacturers are thinking about how to improve the style of the shell. [0003] A common improvement method is to adopt two modes of coating or sticking film, which is to cover or attach a film body with texture or color to the casing to improve the appearance of the casing. [0004] Such as figure 1 As shown, the existing three-dimensional (3dimension, 3D) texture film body is a trans...

Problems solved by technology

[0008] However, the most criticized point by the industry is that the release layer 12 between the first texture 110 and the second texture 130 usually prevents the first texture 110 from being effectively transferred to the second colloid, and the texture of the second texture 130 Too shallow or unable to present, and unable to achieve the desired effect of the industry

[0009] In addition, the use of the first hardening layer 11, the release layer 12 and the second hardening layer 13 multi-layer materials will increase the cost and material waste virtually, so how to improve the existing membrane body becomes the space for the industry to work hard.
