Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to planar, three-dimensional, and spherical light emitters that are utilized in many applications. Chemiluminescence is a reaction between a certain oxalate ester and an oxidizing agent, which brings the substance into an excited state, which then transitions to the ground state, emitting visible light. For example, bis(2.4.5-trichloro -6-carbobutoxyphenyl) oxalate ester, a solution of bis9.10-phenylethynylanthracene dissolved in dibutyl phthalate (hereinafter referred to as oxalate ester), hydrogen peroxide and a catalyst such as sodium salicylate were dissolved in dimethyl phthalate. There is a combination with a solution (hereinafter referred to as an oxidizing agent). Many uses have been developed for luminescent materials that utilize chemiluminescence, as they do not require a power source or generate heat.
All conventional devices emit rod-shaped light, which has the disadvantage that their applications are limited. This is because gases such as carbon dioxide gas are generated as a result of the chemical reaction of the chemiluminescent substance, and cylindrical materials had to be used to withstand the pressure of the gases generated. For example, when trying to make a regular cubic light emitter, there are often problems such as the shape being significantly deformed due to gas pressure, or in some cases, the adhesive part peeling off. It was in an unusable condition.

The present invention aims to provide a luminous material which eliminates the above-mentioned drawbacks, and the gist thereof is to provide two types of luminous material that exhibit a chemiluminescent phenomenon when mixed in a flexible hollow outer container 1 made of gas-permeable plastic. This chemiluminescent material is characterized in that at least one of substances A and B is filled in a breakable hollow capsule 2 and separated from each other. The present invention will be described in detail below with reference to the drawings. As shown in FIG. 1, the flexible plastic hollow outer container 1, which is colorless and transparent, and in other words, transmits light, is made of a material having extremely high gas permeability. use. For example, in addition to materials with high gas permeability, materials with a foam-like structure, materials with a coarse molecular structure, or materials with thinner parts to facilitate permeation are selected and used. .

For example, materials include polyethylene, Teflon, EVA, and mixtures and laminates thereof. Among these materials, select one that is relatively chemically stable. Note that although the drawings illustrate the case of a cube, the same applies to flat or spherical shapes. Further, a film may be formed on the inner surface of the hollow outer container 1 using a chemically stable substance. The hollow capsules 2 and 3 are made of a breakable material such as thin glass. Two types of chemiluminescent substances as described above are contained in the hollow capsules 2 and 3 or the hollow outer container 1, respectively. For example, if a hollow capsule 2 is filled with an oxalic acid ester substance A, an oxidizing agent substance B is placed in the hollow outer container 1 or the other capsule 3. In the present invention constructed as described above, first, the outer container 1 is bent or crushed, and the hollow capsule 2 or 2 and 3 is ruptured, so that the substance inside the hollow capsule 2 and the substance inside the hollow outer container or both hollow capsules are separated. Substances A and B in the capsule are mixed to produce chemiluminescence. As this chemical reaction progresses, gas is generated and the internal pressure increases. The light emission mechanism is assumed to follow the following route.

As the carbon dioxide gas generated as described above becomes higher than the outside pressure, it is pushed out into the outside air from all or part of the gas-permeable outer container through the wall layer. Therefore, it is better for the outer container to be made of a material that selectively allows only carbon dioxide to pass through. Note that one of the causes of deterioration of chemiluminescent substances is the influence of moisture. When using two hollow capsules in the product of the present invention, both oxalic acid ester A and oxidizing agent B are encapsulated in a highly moisture-proof and chemically stable glass material, resulting in better quality improvement and storage stability. is obtained.

As mentioned above, the chemiluminescent material of the present invention is capable of producing three-dimensional luminescence without damaging its shape at all during use, even when the luminous material has a planar, cubic, spherical, or other complex structure, which was previously impossible. There is an effect that can be achieved.
