が妨げられるという問題もある。However, in the toy fireworks described in Japanese Utility Model Publication No. 61-43120, in order to obtain a preferable color of the coating film of the aqueous paint formed on the explosive part, the coating film of the aqueous paint is used. It must be thick to increase the hiding power of the coating. In particular, in the case of a water-based paint using a fluorescent pigment, when the coating film of the water-based paint does not have a sufficient thickness,
A desired color cannot be obtained. On the other hand, however, if the coating film of the water-based paint is thickened, there is a problem that the explosive portion covered with the coating film becomes hard to burn and the burning effect as toy fireworks is reduced. There is also a problem that the coating film of the water-based paint emits a large amount of smoke when the explosive portion is burned, which prevents a clear flame color from being enjoyed.

むことが妨げられるという問題もある。In the toy fireworks described in Japanese Examined Patent Publication No. 6-33991, an oxidizing agent is mixed in the water-based paint in order to make the coating film of the water-based paint more flammable. There is a problem that the aesthetics of the paint and the makeup effect are impaired. In particular, in the case of a water-based paint using a fluorescent pigment, there is a problem that the color development is remarkably deteriorated when an oxidizing agent is mixed. Further, also in this case, there is a problem that the coating film of the water-based paint emits a large amount of smoke when the explosive portion is burned, and it is difficult to enjoy a clear flame color.

の隠蔽力を高めることが可能である。As a result of earnest studies to obtain an aqueous coating material satisfying such requirements, the inventors of the present invention have found that the vinyl acetate resin emulsion as a coating film-forming element in the composition of the conventional aqueous coating material described above is not easily burned and does not burn when burned. In view of the fact that it emits a large amount of smoke, a vinyl acetate resin emulsion is used as a coating film forming element in combination with a water-soluble fibrous polymer resin that is easy to burn and has low smoke at the time of combustion, thus making it difficult to burn and at the time of combustion. The idea is to reduce the proportion of vinyl acetate resin emulsions that emit a large amount of smoke. By the way, in the case of general objects to be coated, water-based paints are also required to be flame-retardant from the viewpoint of fire protection, so it is rather desirable to use a flame-retardant vinyl acetate resin emulsion as a film-forming element. However, as far as the water-based paint to be applied to the explosive part of toy fireworks is concerned, it is desirable to use a flammable coating film forming element, and it is also necessary that the film forming element emits little smoke when burning. is there. In addition, since the water-soluble fibrous polymer resin has a high binding force, it is possible to form a thin coating film. Furthermore, the water-soluble fibrous polymer resin has high water retention and retains a large amount of pigment. Therefore, even when the coating film is thin, the hiding power can be increased.

A toy fireworks characterized in that a vinyl acetate resin emulsion and a water-soluble fibrous polymer resin are used in combination as a coating film forming element of the water-based paint. Incidentally, the coating film forming element is a main component for forming a coating film, and in an opaque paint, pigment particles are bonded by the coating film forming element to form a coating film. That is, although the pigment is a component that constitutes the coating film, it does not form the coating film by itself, but fine particles are dispersed in the film of the coating film-forming element in a finely packed manner so that color and opacity are imparted to the coating film. Is just a component that gives. In the coating composition, the fluid component in which the pigment component is finely dispersed with respect to the pigment component, that is, the component composed of the coating film-forming element and the solvent is nothing but the color-developing agent (vehicle). In the present specification including the claims, the "surface of the explosive part" means the surface of the entire explosive part, that is, the entire surface of the explosive part or a part of the surface of the explosive part. Therefore, in the present invention, the coating film of the aqueous paint may be formed on the entire surface of the explosive portion, but may be formed only on a part of the surface of the explosive portion. The surface of a part of the explosive portion means, for example, the surface of the tip portion of the explosive portion.

なる。In the toy fireworks of the present invention, the vinyl acetate resin emulsion and the water-soluble fibrous polymer are used as the coating film forming element of the aqueous coating material formed on the surface of the explosive portion provided on the shaft portion. Used in combination with resin. Since the total amount of the film-forming elements in the composition of the water-based paint is constant, the proportion of the vinyl acetate resin emulsion in the film-forming element is reduced by the amount of the water-soluble fibrous polymer resin used as the film-forming element. The vinyl acetate resin emulsion is difficult to burn and emits a large amount of smoke when burned, whereas the water-soluble fibrous polymer resin is easy to burn and produces little smoke when burned. Therefore, the coating film of the water-based paint in the toy fireworks of the present invention is easier to burn and has less smoke at the time of combustion, as compared with that in the conventional toy fireworks. Furthermore, since the water-soluble fibrous polymer resin as the coating film forming element of the water-based coating has a high binding force, it is possible to dilute the coating with a large amount of water to form a thin coating film. By forming the coating film thin, the explosive portion will burn more smoothly. In general, coating materials have a reduced hiding power when the film thickness is thin, but water-soluble fibrous polymer resins have high water retention and can hold a large amount of pigments, so the coating film thickness is thin. Even at this time, it is possible to give the coating film a sufficient hiding power and ensure a preferable color of the coating film.

る。As described above, in the toy fireworks of the present invention, a vinyl acetate resin is used as a coating film forming element of the aqueous paint in the coating film of the aqueous paint formed on the surface of the explosive portion provided on the shaft portion. Emulsion and water-soluble fibrous polymer resin are used together. Since the total amount of the film-forming elements in the composition of the water-based paint is constant, the proportion of the vinyl acetate resin emulsion in the film-forming element is reduced by the amount of the water-soluble fibrous polymer resin used as the film-forming element. The vinyl acetate resin emulsion is difficult to burn and emits a large amount of smoke when burned, whereas the water-soluble fibrous polymer resin is easy to burn and produces little smoke when burned. Therefore, the coating film of the water-based paint in the toy fireworks of the present invention is easier to burn and has less smoke at the time of combustion, as compared with that in the conventional toy fireworks. That is, the toy fireworks of the present invention have an excellent burning effect and exhibit a clear flame color. Furthermore, since the water-soluble fibrous polymer resin as a coating film forming element of the water-based paint has a high binding force, the paint is diluted with a large amount of water,
It is possible to form a thin coating film. By forming the coating film thin, the explosive portion burns more smoothly, and the manufacturing cost of toy fireworks can be reduced. Further, in general, the coating material has a reduced hiding power when the film thickness becomes thin, but the water-soluble fibrous polymer resin has high water retention and can hold a large amount of pigment,
Even when the thickness of the coating film is thin, the coating film has sufficient hiding power and it is possible to secure a preferable color of the coating film. Particularly, in the case of a fluorescent pigment, extremely preferable color development can be obtained.
