Description

[Detailed description of the invention] This invention relates to a temperature-sensitive coloring material that develops temperature-sensitive colors in a complex manner depending on the environmental temperature.

The temperature-sensitive color-forming material, which is made by laminating a temperature-sensitive color-forming material layer consisting of a transparent substrate and a temperature-sensitive color-forming material that develops color in a specific temperature range, provides decorative effects to decorative items such as equipment and accessories. Conventional temperature-sensitive coloring materials are used as color enhancers and in many other products in various forms depending on the purpose, but in conventional temperature-sensitive coloring materials, the temperature-sensitive coloring layer that performs the coloring action has a specific temperature range, that is, a single coloring material. Because it is composed of a temperature-sensitive coloring band, it only develops color in a specific temperature-sensitive coloring band, and changes in the thickness of the base that receives this temperature-sensitive coloring material will cause it to change. Although it is possible to temporarily cause a color change due to temperature sensitivity due to differences in thermal conductivity of the base and base, the color pattern itself caused by this temporary color change is based on the constant color of the temperature-sensitive color body. The back and forth color development had no choice but to make it monotonous.

This invention was developed in view of the above points, and the temperature-sensitive coloring material layer of the temperature-sensitive coloring material creates a complex yet fantastic color pattern by coloring, and the color pattern changes according to changes in the environmental temperature. The purpose of the present invention is to provide a temperature-sensitive coloring material whose decorative effect is further increased by changing the temperature-sensitive coloring material. In the above, the temperature-sensitive color-forming material layer is composed of a plurality of temperature-sensitive color-forming materials having different temperature-sensitive coloring bands, which are partially mixed.Hereinafter, one embodiment of this invention will be described in detail based on the drawings. do.

In Fig. 1, 1 is a transparent substrate made of crystal glass, transparent hard plastic, etc.
A temperature-sensitive coloring material layer 2 is laminated on the back surface of this transparent substrate 1 to constitute a temperature-sensitive coloring material 3. The temperature-sensitive coloring material layer 2 is constituted by a plurality of temperature-sensitive coloring materials 4 having different temperature-sensitive coloring regions, which are partially mixed. In forming the temperature-sensitive color forming layer 2, as shown in FIG. When the temperature-sensitive color-forming material 4 is in a semi-dry state, the temperature-sensitive color-forming material 4 is stirred using an appropriate tool, or dripped.
A suitable air pressure (air blow) is applied to the temperature-sensitive color-forming bodies 4 having different temperature-sensitive color-forming bands, and the molding is carried out by partially mixing them, but the invention is not particularly limited thereto. In FIG. 3, a indicates a mixing part of temperature-sensitive coloring bodies 4 having different temperature-sensitive coloring bands. 5
is a paint layer applied to the temperature-sensitive color-forming layer 2 laminated on the transparent substrate 1 after drying, and this paint layer 5 is a paint with relatively heat-absorbing properties such as black or brown. Configure by applying. 6 is paint layer 5
This is a protective layer that is coated with a resin film or the like.

FIG. 2 shows another example of implementation, and this is an example implemented on a base 7 that is the base of a specific ornament. In this embodiment, a paint layer 5 is formed on the bottom surface of the concave portion of the base 7, and a plurality of temperature-sensitive coloring bodies 4 having different temperature-sensitive coloring bands are partially mixed on the top surface of the paint layer 5. The temperature-sensitive color forming layer 2 is laminated. This temperature-sensitive color forming layer 2 is formed on the paint layer 5 by the same means as in the previous embodiment. A transparent substrate 1 is laminated on the upper surface of this temperature-sensitive color forming layer 2.

Since this device is constructed as described above, the plurality of temperature-sensitive coloring bodies 4 having different intricate temperature-sensitive coloring bands forming the temperature-sensitive coloring body layer 2 develop color according to the environmental temperature, and there The mixed part a of the different temperature-sensitive coloring bodies 4 produces a composite color different from the non-mixed part, and the non-mixed part and mixed part a also develop color in a complicated manner, and there exhibits arabesque, pearl-like, and fantastic color patterns, which subtly change in response to changes in environmental temperature.

As described above, according to the present invention, in a temperature-sensitive coloring material formed by laminating a translucent substrate and a temperature-sensitive coloring layer, a plurality of temperature-sensitive coloring bands having different temperature-sensitive coloring bands in which the temperature-sensitive coloring layer is partially mixed is provided. The temperature-sensitive color-forming material layer, which is composed of a plurality of partially mixed temperature-sensitive color-forming materials with different temperature-sensitive coloring bands, has an arabesque or opal shape depending on the environmental temperature. It produces a fantastic and mysterious color pattern, and since this color pattern subtly changes according to changes in the environmental temperature, it is highly decorative and can be used as an accessory whose color pattern moves as the environmental temperature changes. Therefore, by using it in the processing of decorative items, it is possible to further enhance the decorative effect and improve the commercial value of the decorative item. Therefore, it is extremely convenient as a temperature-sensitive coloring material mainly used for decorative purposes. In addition, since the structure is simple, it is easy to manufacture and can be obtained at low cost.
