Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of creating a three-dimensional pattern by applying one or more colors to a button body made of an opaque synthetic resin material, glass material, or the like. Conventionally, a simple concave-convex pattern with a uniform depth was engraved, and colors were applied to the concave areas using a hypodermic needle or a fine brush, which was completely hand-drawn, which was time-consuming, extremely inefficient, and costly. This causes color shift, which tends to cause color shift, and the color effect is poor.

In addition, since the two-colored button was formed by molding a resin material into a different-colored button body and fitting it into a two-colored button, the number of manufacturing steps was increased, and the mold and raw material costs were high.

The method of the present invention relates to a method of making a colored graphic pattern appear three-dimensionally on a button body using an extremely simple method. When forming the button body 1 with a concavo-convex pattern by the above method, a recess 2 having a desired shape or pattern of a certain depth is carved on the front side of the button body 1.

Next, in the first step for coloring the opaque button body 1, the first color paint 2' is applied by spraying or other means to the entire front surface on which the uneven pattern has been engraved. Color.

In this case, a paint film is formed on the sides and bottom of the recess no matter which application method is used, but the thickness is not exactly uniform, and moreover, it is convenient because the bottom is thicker. , this is schematically displayed as shown in Figure 1.

Next, the button body 1 is inserted into the graphic recess 2 and placed in a barrel containing a chip A of an inconvenient size, and the outermost paint is removed by stirring and polishing, leaving the paint film attached to the bottom and side surfaces of the recess. Peel off to expose the button fabric.

Through the above process, the color of the fabric and the color of the paint are changed.
A decorative button with a colored three-dimensional pattern can be created.

Next, the coloring step of a second color other than the fabric color is performed by dyeing. In other words, if a second color paint of the same type as the first color is applied on top of the first color paint 2, the first color will be covered, so a dye will be used to create a color that is slightly lighter than the first color paint. Dye the entire button. As a result, the first color paint appears brightly without fear of being erased by the second color dye, and it is possible to form a button with a two-color graphic pattern.

Therefore, if the button body is colored in advance, an attractive two-color button can be obtained without dyeing the second color.

Furthermore, as shown in FIGS. 3 and 4, if the uneven pattern is made stepwise, the button becomes even more three-dimensional. still,
Figures 5 and 6 illustrate a button with a recess formed on the back side to eliminate threading caused by the sewing thread of the button bulging out on the back side of the fabric. Even if it is a button, there is no problem because the uneven pattern is provided on the front side of the button.

The present invention makes it possible to reliably and easily remove unnecessary colored paint using a chip after coloring the entire desired uneven pattern previously engraved on the button body 1 as described above, and also to polish the outer surface of the button. This not only makes it easier to color the concave parts of narrow patterns and prevents unwanted peeling, greatly improving work efficiency, but also allows for three-dimensional and brilliant coloring that has never been seen before. This is an excellent invention that allows for the mass production of decorative buttons.

Claims (1)

[Claims] 1. Carve a desired uneven pattern on the front side of an opaque button body made of resin or glass material, apply paint to the entire front side of the button including the concave portions of the uneven pattern, and after drying, The button body is agitated and polished in a barrel containing a chip that is too large to fit into the concave part, and the paint applied to areas other than the concave part of the graphic pattern is peeled off to expose the base color of the button body, and then colored. A method for forming a colored three-dimensional pattern on a button, characterized in that the graphic pattern appears three-dimensionally.
