Description

[Detailed Description of the Invention] This invention relates to a decorative material for handicrafts used to decorate products that come into contact with the human body during use.

For example, portable items such as handbags and pouches, and accessories such as brooches and pendants are decorated with decorative materials by handcraft, but conventional decorative materials for handicrafts such as beads and sand grains have unique colors and colors at the time of manufacture. The color tone is fixed, and the designs and colors of products made using the decorative material are also determined by the arrangement at the time of product manufacture, and do not change at all during product use. Therefore, there was little variation and the user or viewer did not feel dynamic interest.

In view of the above points, this idea was created as a handicraft that allows the user to enjoy dynamic changes in the color, tone, or pattern of the accessory when the user touches the accessory. The purpose is to provide decorative materials for use.

Next, one embodiment of this invention will be described based on the drawings.

FIG. 1 shows the basic structure of the decorative material A for handicrafts according to this invention.

The decorative material A according to this invention is based on strips a having an arbitrary shape. Raw materials for the strips include, for example, plastic, glass, metal, wood,
Alternatively, various materials such as sand can be used. These dimensions and shapes are determined depending on the use of this decorative material, as will be described later.

According to this invention, a metal plating layer b having an arbitrary color is provided on the surface of the decorative material.
The type of metal used also depends on the desired color depending on the purpose, and metals that can provide decorative colors such as gold, silver, copper, zinc, tin, nickel, and chrome are used.

According to this invention, the surface of the strip a having the metal plating layer b as described above is coated with thermochromic dye c, preferably over the entire surface or partially. The banding method may include a method in which the strip is immersed in a solvent containing the dye, taken out and dried, or a method in which the strip is vapor-deposited.

The thermochromic dye is preferably one that is decolored at room temperature and develops a color that is different from the color of the metal plating when the temperature is about the same as human body temperature. Alternatively, it may be colored at room temperature and faded to become colorless when the temperature reaches the same level as body temperature. In addition, the thermochromic dye may be used in a single color, or in a plurality of colors.

Next, to explain the effect of the decorative material having the above-mentioned structure, if a thermochromic dye that is decolored at room temperature is used, the surface of the decorative material at room temperature will have no color. The color unique to the metal plating layer appears. On the other hand, when you touch the decorative material with your body and bring it to a temperature comparable to your body temperature, the thermochromic pigment reacts and develops a color different from that of the metal plating. In addition, if thermochromic pigments that develop color at room temperature are used, the color of the pigment will appear on the surface of the decorative material at room temperature, and when the temperature is about the same as body temperature, the color of the pigment will change. As it disappears, the color of the metal plating inside becomes visible.

Considering the dimensions and shapes of such decorative materials in relation to their uses, (a) various shapes of relatively small dimensions, such as star shapes, diamond shapes, curved beads, ovals, or various flower shapes;
By housing a large amount of these decorative materials in various transparent containers B as shown in FIG. 2, imitation jewelry can be expressed using these decorative materials A.

In addition, the decorative material (b) can be used as beads by making the strip a into a spherical shape, for example, with or without a through hole in the center. Furthermore, (c) by using small particles, it can be used as a sand painting material.
Any drawing is possible.

The decorative material expressed in the shape of beads or sand grains can be arranged on the surface of the above-mentioned accessories or portable items such as handbags along a desired pattern to form an arbitrary pattern. Third
P in the figure shows an example in which a pendant is formed by laying a large number of decorative materials A on the upper surface of a base material C.

The various products decorated with a large number of decorative materials placed on their surfaces as described above will retain their color at room temperature while they are unused and stored or used in a position that does not come into contact with the body. Or, a certain artistic idea or emotion is expressed by a combination of colors, but if you touch it with your hand or press it against a part of your body and apply body heat during use, it may As a result of the reaction, the area changes color,
A color, pattern, or design appears that expresses a different thought or emotion than before.

When the temperature returns to normal, the original pattern will be restored again. Therefore, it is possible to enjoy repeatedly changing the color and pattern of the surface of the product.

Figure 3 (b) shows an example in which a picture of a dolphin appears on the surface of a pendant in response to body temperature.

As mentioned above, the handicraft decorative material invented by this invention has a metal plating layer on the surface of the strip having an appropriate shape depending on the purpose, and has a thermochromic pigment on the surface that reacts with body temperature. Because it is a decorative material, large amounts of this decorative material can be used to draw arbitrary designs and patterns on the surfaces of personal items and accessories.
Furthermore, when the product is touched by the body during use, the color, tone, or design changes, making it possible to provide a decorated product that is highly entertaining, surprising, and entertaining.
