Problems solved by technology

[0008] Compared with the known technology, in the process of in-mold transfer printing technology, in order to make the appearance of injection molded parts have a sense of layering, it needs to rely on multiple color printing technology, or to partially coat the structure on the surface of the substrate before the substrate is coated with a protective layer. , so as to create a three-dimensional structure on the surface, but the local coating structure cannot produce fine microstructure patterns
If the hairline pattern is produced by the known brush wheel method, although a hairline surface with a three-dimensional touch can be formed on the surface, the dross generated during the brush wheel manufacturing process will cause difficulties in yield and process.

[0075] Please refer to Figure 4 Shown is a schematic diagram of the flexible mold of the first embodiment of the present invention. The flexible mold 3 of this embodiment is used in the three-dimensional structure transfer printing process. The so-called three-dimensional structure transfer printing process includes thermal transfer printing, three-dimensional thermal transfer printing, in-mold injection transfer printing, and water transfer printing. A three-dimensional structure or pattern is produced, and the mold used therein includes but is not limited to a roller or a plate.

[0076] The flexible mold 3 includes a base material 31 and a microstructure pattern layer 32, the microstructure pattern layer 32 is a layer with a microstructure pattern surface, the microstructure pattern layer 32 has a first pattern 321, and the first pattern 321 is located in the microstructure pattern. On the surface of the structural pattern layer 32 , the microstructure pattern layer 32 is...

[0089] Please refer to Figure 9A and Figure 9B shown, where Figure 9A is a schematic diagram of the flexible mold of the second embodiment of the present invention, Figure 9B It is a schematic top view of the microstructure pattern layer of the flexible mold of the second embodiment. The flexible mold 3a includes a substrate 31 and a microstructure pattern layer 32a, and the microstructure pattern layer 32a has a first sub-pattern 322 of a hairline pattern and a second sub-pattern 323 of a three-dimensional pattern . Wherein, the material of the substrate 31 can be polyethylene terephthalate (Polyethylene Terephthalate, PET), polycarbonate (polycarbonate, PC), non-extended polypropylene (Casted Polypropylene, CPP), co-extruded oriented polypropylene Propylene (Oriented polypropylene, OPP). And the thickness of the substrate 31 is 10 μm to 250 μm. In this embodiment, the substrate 31 is exemplified by polyethylene terephthalate (PET) with a thickness of 50 μm.

Abstract

The invention provides an in-mould decoration material. A soft mould is used for a transfer print process of a three-dimensional structure; the soft mould comprises a base material and a micro-structure pattern layer. The micro-structure pattern layer is provided with a first pattern and the micro-structure pattern layer is arranged on the base plate, so that the sense of touch is increased, even the color saturation is improved; and a product in the prior art cannot be compared with the in-mould decoration material.

Description

[0001] This application is a divisional application based on the invention patent application entitled "Flexible Mold and Manufacturing Method, In-Mold Decoration Materials and Injection Molded Appearance Parts" with application number 201010127113.X filed on February 12, 2010. technical field [0002] The present invention relates to a soft mold used in In-Mold Roller (In-Mold Roller, IMR, IMR) and its manufacturing method, and an in-mold decoration material with the soft mold, as well as a mold made of the in-mold decoration material. Injection-molded exterior parts. Background technique [0003] Today's consumer products pay more attention to packaging, especially texture and personalization, so as to stimulate consumers' desire to buy. Therefore, there are more and more different changes in the casing design of electronic products now to meet the user's requirements for texture. On the contrary, how to change the monotonous shell of the object so that it has a colorful ...
