And the other part is the transparent part 9b. Next, an appropriate light source, for example, a mercury lamp, an arc lamp, or an ultraviolet lamp is irradiated from above the design film 9 to expose the photosensitive emulsion film 8 in the portion corresponding to the transparent portion 9b. (See Figure 5). Then, the design film 9 is removed from the base material 1 and the base material 1 is immersed in a developing solution to develop and fix the photosensitive emulsion film 8. By this development and fixing, the unsensitized film 8a of the photosensitive emulsion film 8, that is, the character and graphic portions are melted, and the character and graphic portions are removed by washing with water or hot water to remove the unexposed light as shown in FIG. Decorative layer 7 under chemical film 8a
Is expressed. At this time, the photosensitive film 8b of the photosensitive emulsion film 8 remains. That is, the unsensitized film 8a of the photosensitive emulsion film 8 is water-soluble and the sensitized film 8b is poorly water-soluble. For example, the unsensitized film 8a may be formed of a cloth or the like soaked with a caustic soda solution or a synthetic detergent solution. It has the property that it can be removed by wiping. Incidentally, when a physical action is exerted on the substrate 1 during the developing and fixing work, the photosensitive film 8 of the photosensitive emulsion film 8 is
Be careful because b is damaged. Sixth Process (Design Removal Process) The sixth process as the design removal process will be described with reference to FIG. 7. The decorative layer 7 under the unphotosensitized film 8a exposed at the time of development and fixing in the photosensitized film forming step is dissolved with a lacquer thinner, then removed and naturally dried. Then,
The opaque portion 9a of the design film 9 is formed on the base material 1.
A design cutout groove D representing a character or a figure corresponding to is formed, and the depth of the design cutout groove D is the laminated portion of the decorative layer 7 and the photosensitive film 8b of the photosensitive emulsion film 8. The upper surface of the acrylic base material 1 is exposed at the bottom of D. Since the photosensitive film 8b of the photosensitive emulsion film 8 is insoluble in an organic solvent such as lacquer thinner, only the cosmetic layer 7 shown above is dissolved and removed by the lacquer thinner. .. Seventh Step (Removing Step) The seventh step as the removing step will be described with reference to FIG. 8.
