Terms such as those defined in the commonly used dictionaries should be construed as having meanings consistent with the meanings in the context of the related art and shall not be construed in ideal or excessively formal meanings unless expressly defined in this application. Do not.

In the present specification, the first to second and the second to refer to different components are not limited to the order of manufacture, and their names are used in the detailed description and claims of the present invention. May not match.

First, as shown in FIG. 1, the method of manufacturing a decorative sheet having a pattern layer by heat molding first prepares a fabric film 10 made of a synthetic resin (eg, PC, PET, PU, etc.).

As shown in the upper right dashed line in Fig. 1, the fabric film 10 is a pre-adhesive 11 in advance to the other side of the fabric film to adhere the final decorative sheet to the electronic device, such as a mobile phone or other decorative sheet attached object It is preferable that it is already formed at the source (before the start of the step (a)), and the normal release film R1 is attached to protect the adhesive layer 11.

This is also considering the reality that the fabric film manufacturer and the decorative sheet manufacturer is commercially separated.

However, in essence, the raw film, which is usually supplied in roll form, is cut into a cutting film larger than the final decorative sheet (2 times, 4 times, etc.) to form the color layer 20 and the pattern layer 30.

The method of separately forming the adhesive layer before and after the color layer 20 and the pattern layer 30 forming step not only reduces productivity.

The post-formed adhesive layer impairs the transparency of the whole to reduce the light transmittance, thereby impairing hardening, or finally impairing the visibility of the pattern or the display part of the display window, and it is difficult to accurately match the pattern part or the viewer with the decorative sheet attached object. Since the problem occurs that the accuracy of the security is not secured, it is to prevent this.

In the present specification, for convenience, thin 'films' are stacked or unit layers stacked above and below the original 'film' are referred to as 'sheets' to distinguish them from 'film' or unit 'layer' structures.

Subsequently, a step (a) is performed to form a color layer 20 including a color part by printing (for example, graphic printing) or deposition on one surface of the prepared fabric film 10.

Next, the step (b) of applying the hardening liquid 30L on the color layer 20. 화 The curing liquid (30L) is commercially available, and has appropriate physical properties (eg, flowability and viscosity) and, if necessary, contains a known component for implementing scratch resistance, abrasion resistance, and chemical resistance. It is suitable for securing the simplicity, productivity and cost competitiveness of the process by eliminating the process of introducing additional lamination structure to secure the quality and implement the corresponding performance.

The pattern portion of the hardened liquid 30L is formed through the light-transmitting tool T in which the pattern T1 is formed (the term 'tool' is selected by collectively selecting the light-transmitting mold and moving equipment instead of the restrictive term of 'mould'). Forming a pattern layer 30 including (31), and then goes through step (c) of irradiating the cured lamp (L) by curing.

The pattern T1 of the light-transmitting tool T may be a pattern that can be distinguished by human touch, but may also be a micro pattern such as a hologram visually distinguishable for a more beautiful design. The micropattern is produced using a conventional publicly known method (such as pole making method).

If the main process (a) (b) (c) of the left in Figure 1 is for the decorative sheet (D) attached to the back of the mobile phone as shown in [A] of Figure 2,

As shown in contrast to the one-dot chain line in turn on the right side, as shown in [B] of FIG.

That is, based on the right side of FIG. 1, in step (a), the light emitting part 23 surrounded by the color part 21 is formed in the color layer 20.

In step (b), the light-curing liquid 30L is penetrated into the light transmitting part 23,

In the step (c), the non-pattern part 33 is surrounded by the pattern part 31 of the pattern layer 30 and overlaps with the light transmitting part 23.

The overlapping portion of the light transmitting portion 23 and the non-pattern portion 33 forms the viewing portion W (see FIG. 2B).

In general, the light emitting area and the viewer W in the outer frame portion of the mobile phone display window require precise matching.

In the present specification, the expressions `` enclosed '' by the color part 21 and the pattern part 31 and the non-pattern part 33 are the shapes in which the color part 21 and the pattern part 31 form a closed circuit. In addition to surrounding the light-transmitting portion 23 and the non-pattern portion 33, it should be interpreted as a concept that encompasses the open form and the adjacent arrangement form.

Next, as shown in the cross-sectional view within the dashed circle on the right with respect to [A] mobile phone backside decoration sheet (D) and [B] mobile phone frontside decoration sheet (D) of FIG.

It is preferable that the adhesive layer 11 is previously formed on the other surface of the raw film 10 of step (a), and the release films R1 and R2 are attached to the final pattern layer 30 as well as the adhesive layer. It is desirable to have.

In addition, after the step (c), it is preferable to further go through the step of (d) cutting and (e) attaching the separating tip (S1) (S2) to each of the release films in order to produce the final decorative sheet (D). .

The cutting step (d) may use a Thompson method (commonly referred to as 'domusong', etc. using Japanese terms in the industry) to secure productivity and accuracy.

Thus, the decorative sheet (D) manufactured by the manufacturing method according to the present invention is a display window or a rear protective film of a mobile device such as a mobile phone,

It can be used for the production of decorative sheets for various products and industries, such as skins in which button parts are integrated with various buttons of electronic products, for example, a remote controller.

In the above description, the conventionally known techniques related to the composition and physical properties of the hardening liquid, the type of the original film, the specific printing or deposition process, etc. are omitted, but those skilled in the art can easily infer, infer, and reproduce them.

In addition, in the above description of the present invention with reference to the accompanying drawings, a specific process order and a specific shape of the decorative sheet mainly described, but the present invention can be variously modified, changed and replaced by those skilled in the art, such modifications, changes and substitutions Should be construed as falling within the protection scope of the present invention.
