JPS60320Y2 - Temperature-sensitive coloring material - Google Patents

Description

[Detailed description of the invention] The temperature-sensitive coloring material, which is composed of a temperature-sensitive coloring material that develops color in a specific temperature range, can be used as a material that enhances the decorative effect of decorative items such as equipment and accessories, and for many other purposes. They are used in various forms depending on the purpose of the product, but conventional temperature-sensitive coloring materials consist of a single layer of temperature-sensitive coloring material, so the color change due to temperature is due to this temperature-sensitive coloring material. Temporary color changes occur due to thermal conductivity due to differences in the thickness of the substrate receiving the coloring material, but the color pattern itself is monotonous due to the constant coloration of the temperature-sensitive coloring material. Then there was a place where the monkey could not escape.

There is also a method for making a pattern appear on a temperature-sensitive coloring material made of one layer of temperature-sensitive coloring material, and this method involves forming a gate convexity in the recess, that is, the bottom of the base body that receives the temperature-sensitive coloring material. It seemed like it was a step forward, whether it was intended to give a change to the image or to enhance the decorative effect of ornaments.

In view of the above points, the present invention has been developed by forming unevenness in the concave portion of the substrate that receives the temperature-sensitive coloring material, so that complex color patterns can be easily obtained as composite colors (7), and the decoration thereof The purpose is to provide temperature-sensitive coloring materials with enhanced thermal effects and wide range of uses.
It consists of a stack of three or more temperature-sensitive color materials.

An example of implementation of the present invention will be described in detail below based on the drawings.

Figures 1 and 2 show an example in which a two-layer temperature-sensitive coloring body is used in a pentad. 1 is the first temperature-sensitive coloring body, 2
is a second thermochromic material having a different thermochromic band from the first thermochromic material 1, and the first thermochromic material 1 and the second thermochromic material 2 are laminated to form a thermochromic material. do.

In the drawing, a second moisture-sensitive color body 2 shaped like a flower pattern is laminated on a part of the first moisture-sensitive color body 1.

3 is a base made of metal or plastic that serves as a frame for the decorative part of the pentad and receives the first temperature-sensitive color body 1 and the second temperature-sensitive color body 2; 4 is the first temperature-sensitive color body 1 and the second temperature-sensitive color body 2; A protective layer is interposed between the contact surface between the color forming body 2 and the substrate 3, and the first temperature-sensitive color forming body 1 and the second temperature-sensitive color forming body 2 received by the base body 3 are covered with a transparent material layer 5. ing.

Reference numeral 6 denotes a hook ring such as a genin provided on the base body 3 which also serves as the frame of the pentad.

Therefore, the laminated portion a of the first temperature-sensitive coloring body 1 and the -Y-th temperature-sensitive coloring body 2 exhibits a composite color due to the difference in their respective temperature-sensitive coloring gamuts (-). It should be a different color from the middle layer part l].

For example, in the case of a real moat, the laminated part a becomes a flower pattern and has four faces.

Figure 3 shows an example of another implementation of the temperature-sensitive coloring material.
1. Coating the first temperature-sensitive color forming member 1 on the transparent resin film 7, and further covering the first temperature-sensitive color forming member 1 with a protective film 1, 8, and forming a sheet-like first temperature-sensitive color forming member 9. (Similarly to -1, second temperature-sensitive color forming body 2 is added to transparent resin filter t and 10: 1-
5. Add the ink and then cover the second temperature-sensitive coloring body 2 with the protective film 1.
1 to form a sheet-like second temperature-sensitive coloring member 12, and a second temperature-sensitive coloring portion +fl'12 shaped appropriately was laminated on the first temperature-sensitive coloring member 9. It is something.

5. Although the above embodiment shows an example in which two temperature-sensitive coloring bodies 1 and 2 having different temperature-sensitive coloring bands are laminated, it is of course possible to use a multilayer structure.

As described above, the present invention is a laminated layer of two or more temperature-sensitive coloring materials with different temperature-sensitive coloring bands.
The laminated parts exhibit composite colors due to differences in temperature-sensitive coloring bands,
The color is different from that of the single layer part, and the product of this thermochromic color body is 5.
The change in hue between the layered part and the single layer part appears as a color pattern or color pattern, and a complex color pattern that could not be seen with conventional thermosensitive coloring materials consisting of an intermediate layer can be obtained, resulting in a single thermosensitive coloring material. Since it is possible to obtain arbitrary patterns and designs by shaping the body into a specific shape, by using it in the processing of ornaments6, it is possible to further enhance the decorative effect and improve the commercial value of the ornaments. It is extremely convenient as an isothermally sensitive coloring material that can be widely used in various forms depending on the purpose of the product, as well as decorative items, and its simple structure makes it easy to manufacture. It has the advantage that it can be obtained at low cost.
