Description

[Detailed description of the invention] [Purpose of the invention]

(Industrial Application Field) This issue 11 relates to a marking method used to form marks on parts to be marked such as automobiles and home appliances, and in particular, to a marking method that is used to form marks on parts to be marked such as automobiles and home appliances, and in particular, to create a texture that is integrated with the paint film on the part to be marked. The present invention relates to a marking method suitable for forming tall marks. (Prior art) Conventionally, as the above marking method, 7JS7
There were those shown in Figures 1 to 10. That is, as shown in FIG.
7 when forming a mark 101 on the door panel 00. It was based on the steps shown in FIGS. 8 and 9. First, as shown in FIG. 7, a release paper 106 is pasted on one side of a colored layer 105 made of a polymeric material such as polyvinyl chloride, which has been formed into a pictogram of a mark 101 shown in FIG. A marking film 1 with a three-layer structure in which an application paper 107 is attached to the other side of the color layer 105
08, undercoat film 102. After the release paper 106 has been peeled off, a marking film 108 is pasted onto the surface of the portion to be marked 100 on which the intermediate coating film 103 and the top coating film 104 have been applied. Then, as shown in FIG.
7 is peeled off, leaving only the colored layer 105 on the top coat 104, and the pictogram of the mark 101 is formed on the portion 100 to be marked. In addition, as shown in FIG. 9, when applying a clear coating film 10 such as metallic coating, clear coating Nl is applied to the surface of the top coat T12104 on which the colored layer 105 is pasted as shown in FIG. 09 to form the pictograph of the mark 101 on the marked portion 100. (Problems to be solved by the invention) However, in the above-mentioned conventional marking method,
Since the colored layer 105 forming the mark 101 is pasted on top of the top coat/Ii film 104 applied to the portion to be marked 100, as shown in FIG.
Since an uneven step is formed between the color layer 105 and the colored layer 105, for example, washing a car. There was a problem in that it was difficult to perform the work because it was necessary to take care not to peel off the wax and the like when performing Pode maintenance. In addition, as shown in FIG. 9, when a clear coating film 102 is applied to the surface of the top coat v104 to which the colored layer 105 is attached, the top coat film 104 with uneven steps shown in FIG. Since the clear coating film 102 is applied along the surface of the clear coating film 102, uneven steps are formed in the clear coating film 102 as well, which poses a problem of impairing the sense of quality. Therefore, in order to eliminate the uneven steps formed on the clear coating film 109, it may be possible to correct the unevenness and repaint it after making it flat, but this would only increase the amount of paint consumed and the cost. However, there was a problem in that the number of man-hours increased and productivity deteriorated. Furthermore, since the colored layer 105 was made of a polymeric material such as polyvinyl chloride, which had relatively poor paint adhesion, there was a problem in that the adhesion of the clear coating film 102 was also poor. (Objective of the Invention) This invention was made in view of such conventional problems, and it is possible to form a mark on a smooth surface that is integrated with the paint film of the part to be marked. It is an object of the present invention to solve the above-mentioned conventional problems by providing a marking method.

[Structure of the invention]

(Means for Solving the Problems) The marking method according to the present invention includes attaching a release paper to one side of a colored layer expressing a predetermined pictogram, and
Using a marking film on the other side of the colored layer, a masking paper having a shape corresponding to the pictograph and concealing the pictograph, and an application paper covering the entire surface including the pictograph part are attached, The marking film is characterized in that the release paper of the marking film is removed and the marking film is pasted onto the intermediate coat film of the part to be marked, the application paper is removed, a top coat film is applied, and then the masking paper is removed. If necessary, a clear coating film is further applied after removing the masking paper, and if necessary, the surface of the colored layer, that is, the gap between the masking paper and the masking paper has adhesion to the clear coating film. It is characterized by the provision of an imparting layer. (Example) Hereinafter, an example of the marking method according to the present invention will be described.
This will be explained based on FIGS. 6 to 6. 1 to 4 show an embodiment of the marking method according to the present invention, and in one embodiment, a solid color case is shown. That is, in Figure 71IJ1, the marked part 1
