[Action]

 That is, in the fishing tackle of the present invention, a temperature-sensitive discoloration region in which the color tone changes at a predetermined temperature as a boundary is formed in a part or the whole of the plowed body. Therefore, since the temperature-sensitive discoloration area of the plow body senses the water temperature of the fishing spot and changes its color tone, it is possible to estimate the type of fish that is easy to catch according to the water temperature, and the results of fishing can be improved. Will be things.

Next, this invention will be described in detail.

As the temperature-sensitive color changing material for forming the temperature-sensitive color changing region of the present invention, a material whose color tone changes at a predetermined temperature is used. Specifically, it is preferable that the color tone changes at a temperature equal to or slightly lower than the water temperature of the fishing ground. However, since the water temperature changes due to seasonal factors and other factors, if multiple temperature-sensitive discolored areas that change color at different temperatures are formed, the color tone will change in response to changes in the water temperature at the fishing ground. It becomes possible to estimate the water temperature more accurately.

Further, as the temperature-sensitive color-changing material forming the temperature-sensitive color-changing region, a material that loses or reveals a color tone at a predetermined temperature may be used. When such a temperature-sensitive color-changing material is used, the temperature-sensitive color-changing area senses the water temperature and loses the color tones of red, blue, brown, black, etc. It becomes possible to estimate the water temperature of the fishing ground more accurately.

As the temperature-sensitive discolorable material, for example, a mixture mainly composed of three components of an acid-developing substance, an acidic substance and a solvent can be used.

The acid-developing substance reversibly exhibits the phenomenon of being developed by the above-mentioned acidic substance and being discolored or discolored by deoxidation, and 3,6-bisdiethylamino-o-carboxyphenylxanthene lactam, 3 -Xanthene-based compounds that develop a red to orange-red color, such as diethylamino-7,8-benzo-o-carboxyphenylxanthene lactam and 3-diethylamino-7-chloro-o-carboxyphenylxanthene lactam. There is a substance. Further, 4,4-bisdimethylaminodiphenyl-o-carboxyphenylmethanelactam, 4,4-bisdiaminodiphenyl-o-carboxyphenylmethanelactam, 4,4-bisdimethylaminodiphenyl-p-dimethylamino-o-carboxy Examples include phthalide-based substances that develop a purple to blue color such as phenylmethane lactam. Further, yellowish ones such as 3,6-diethoxyfluorane can be used. These are used alone or in combination to obtain a desired color.

The acidic substance develops the above-mentioned acid-developing substance and has a function of determining the color intensity, and includes dibenzotriazole, 4-laurylaminosulfonylbenzotriazole, 5-butylbenzotriazole, and 1-butylbenzotriazole. , Triazoles such as dibutyl 2,3-triazole dicarboxylate, hydroxyl group-containing substances such as bis-p-hydroxyphenylmethane, methyl β-oxynaphthoate, phenol formaldehyde, stearic acid, anthracenecarboxylic acid, organics such as phytic acid Acid, anthranilic acid toluidine salt, ammonium stearate, 1-acetylbenzotriazole, 1-benzoylbenzotriazole, 3-acetylbenzotriazole, 3-benzoylbenzotriazole, and other salts, and easily decomposable acid derivatives But In addition it will be used.

The solvent rapidly dissolves either the acid-developing substance or the acidic substance at a specific temperature, thereby inhibiting the binding between the two. Here, the specific temperature is the color change temperature, and the color change temperature can be freely adjusted by selecting the type of the solvent. Typical examples of the solvent include alcohols such as cetyl alcohol, dodecyl alcohol, oleyl alcohol and octyl alcohol, acid amides such as stearyl amide, acetoacetylanilide and oleyl amide, esters of glyceride stearate, lanolin and diphenyl phthalate. Heat-fusible solids such as isophorone, decalin, naphthalene, petroleum, rapeseed oil, wax and paraffin wax can be used.

The temperature-sensitive color-changing substance is usually formed by dissolving three components consisting of the above-mentioned acid-developing substance, acidic substance, and solvent, or a mixture thereof with other additives into a solid solution in a non-thermoplastic resin. This non-thermoplastic resin is made by embodying it and coating it with the following coating. Polyurethane resin, epoxy resin, melamine resin, phenol resin, furan resin, diallyl phthalate resin, epoxy phthalate resin, etc. Can be used. In addition, as a compound for forming a film for coating and protecting the above granular solid solution, natural polymer compounds such as alginate, carrageenan, pectin, chitosan salt, cationized starch, carboxymethylated starch, carboxylated guar gum. Semi-synthetic polymer compounds such as polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylic acid amide, polymaleic acid copolymers, and the like, and mixtures thereof are used. The above-mentioned other additives include a surfactant and a bulking agent.

The above-mentioned thermochromic material is used in the form of a fine powder so that it can be easily kneaded into a synthetic resin which is a molding material for a hollow body. It may be in the form. Further, it may be encapsulated in microcapsules made of epoxy resin, urea resin or the like. The temperature-sensitive color-changing material thus sealed and housed in the microcapsules undergoes a temperature-sensitive color change inside the microcapsule, so that the color tone is clearly revealed and the durability is improved. Examples include "Chromic Color" manufactured by Matsui Dye Chemical Industry Co., Ltd. and "Dythermo" manufactured by Dainichi Seika Chemical Industry Co., Ltd.

Next, examples will be described.
