[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a composition for coloring a cleaning liquid, and more particularly, to a composition for coloring a cleaning liquid for coloring, for example, flushing water of a flush toilet. Conventional Technology Conventionally, for example, in ordinary flush toilets in homes and buildings, blue-colored flushing water or sterilizing water is generally used to give a visually clean and refreshing feeling after use. ing. In particular, when a limited amount of washing water needs to be used repeatedly, such as in vehicles, aircraft, ships, etc., the washing water is sterilized and disinfected, and the unpleasant human urine color is hidden to give a sense of cleanliness. For this reason, cleaning water colored blue is mainly used. However, many of the colorants conventionally used to color wash water blue usually do not last long after the wash water has been used, even after its final treatment stage.
Depending on the treatment method being used, the color may not be decolorized at all or only incompletely, so that it is discharged as colored wastewater, causing secondary pollution. In other words, blue coloring agents such as methylene blue and threne blue have been conventionally used to color cleaning water blue, but in neutral or alkaline conditions, these blue colorants can be used to remove excess chlorine and hypochlorite. Even when treated with a chlorine-based decolorizing agent such as an aqueous solution, the color is only completely or incompletely decolorized, so the wash water must be treated with ordinary household purification treatment, or with ordinary sewage water treated with air aeration, activated sludge treatment, etc. Not only by treatment, but also by high-grade treatment such as chlorine sterilization when discharging into rivers etc. after these normal treatments.
Decolorization is extremely difficult, and therefore, there is currently a strong demand for the development of a cleaning liquid colorant that can be easily and completely decolorized after processing human waste. The inventors of the present invention have considered the above-mentioned problems and have conducted extensive research. As a result, certain polymethine-based colored compounds containing pyrazolone rings have been found to be effective against extremely low concentration chlorine-based treatment agents, and furthermore, in ordinary microbial treatment. Therefore, the present invention was completed by discovering that the color can be completely and easily decolored. Problems to be Solved by the Invention Therefore, one object of the present invention is to provide a composition for coloring a cleaning liquid that can be easily and completely decolored after being used for cleaning a flush toilet, etc. Specifically, it is an object of the present invention to provide a cleaning liquid coloring composition that can be easily decolored by treatment with an extremely low concentration chlorine-based treatment agent and further by ordinary microbial treatment. Means for Solving the Problems The cleaning liquid coloring composition according to the present invention has the general formula: (However, A ¹ and A ² each independently represent (a) hydrogen (b) lower alkyl group, (c) -COOM or -SO ₃ M (However, M is an alkali metal, an alkaline earth metal, ammonium, or lower alkyl ammonium) as a substituent, or (d) -COOM or -SO ₃ M (where M is the same as above) as a substituent, and

In addition, when the above aromatic ring does not have these additional substituents, and when the additional substituent is a hydroxyl group, a lower alkoxy group, or a halogen, -COOM is added so that the colorant has high water solubility.

When n is 0 or 1, the colorant exhibits a yellowish or reddish color, but when n is 2, it exhibits a blueish color. In the present invention, a blue coloring agent in which n is generally 2 is dissolved in order to impart a visually clean and refreshing feeling to the cleaning liquid.
However, if necessary, a coloring agent in which n is 0 or 1 may be used in combination, for example, in order to increase the effect of concealing unpleasant components such as human urine color, or for other reasons. If desired, colorants in which n is 0 or 1 can be used alone. Next, preferred examples of the colorant used in the present invention will be shown. The above coloring agent is a case where n is 2 in the general formula, but an example of a coloring agent where n is 1 will be given.

It can be easily manufactured by a conventionally known method. That is, in the above general formula, to obtain a colorant where n=0, 2 moles of the pyrazolone derivative are mixed with 1 mole of ethyl orthoformate or diphenyl group formamidine, and to produce a colorant where n=1, the pyrazolone derivative is mixed with 1 mole of ethyl orthoformate or diphenyl group formamidine. 2 mol of the pyrazolone derivative with 1 mol of propenedianil hydrochloride or tetramethoxypropane and, for the production of colorants where n=2, 2 mol of the pyrazolone derivative with glutacondialdehyde dianyl hydrochloride, dinitrophenylpyridinium chloride or A condensation reaction is performed with N-cyanopyridinium bromide and the like using a base catalyst. As the chlorine catalyst compound, for example, triethylamine, pyridine, piperidine, ammonia gas, etc. are used, and as the reaction solvent, a solvent that dissolves the pyrazolone derivative, such as methanol, ethanol, ethylene glycol monoethyl ether, dimethylformamide, dimethyl sulfoxide, etc. is used. etc. are used. The condensation reaction is usually carried out at a temperature below the boiling point of the solvent used and under normal pressure.
Some colorants with = 2 are unstable to heat, so the reaction is carried out at low temperatures, e.g.
It is often advantageous to carry out the process at a temperature of .degree. Incidentally, when a mixture of 1 mole each of different pyrazolone derivatives is condensed with glutacondialdehyde dianyl hydrochloride, a mixture of pyrazolone structures of the same and different pyrazolone structures at both ends of the polymethine chain is obtained,
If desired, these may be separated into a single coloring agent, but in the present invention, there is no problem in using these as a mixture. Effects of the Invention The coloring agent according to the present invention can be easily and completely decolored with a small amount of chlorine decolorizing agent. Therefore, when such a coloring agent is used, for example, to color water for flushing toilet bowls, the colored flushing water not only gives a clean and refreshing feeling, but also hides the unpleasant color of human urine, etc.
After the colored washing wastewater is treated with human waste, it is immediately and completely decolored with a small amount of chlorine-based decolorizing agent. Furthermore,
It can also be completely decolorized by microbial treatment, which is used in normal sewage treatment.

Then, a solution of 7 parts of anhydrous potassium acetate dissolved in 50 parts of ethanol was added to the above reaction mixture, followed by stirring for 5 hours. Thereafter, the product was filtered, washed with acetone, and dried to obtain 14.8 parts of dark blue crystalline powder. This product took on a blue color when dissolved in water. Synthesis Example 3 (Synthesis of the colorant (26)) 7.5 parts of 1-(p-phenoxy-m-sulfo)phenyl-3-carboxy-5-pyrazolone and 2.6 parts of propendianyl hydrochloride were placed in 70 parts of ethanol. , add 6 parts of triethylamine to this,
After reacting for 2 hours at a temperature of 40 to 50°C, a solution of 3.6 parts of potassium carbonate dissolved in 10 parts of water was added to precipitate the produced colorant as a potassium salt.

The composition was cooled and solidified to produce a solid composition for coloring a cleaning liquid according to the present invention. When this was immersed in a 20-capacity washing water tank of a household flush toilet, it gradually dissolved and gave blue washing water. Similarly, solid cleaning liquid colorant compositions were obtained using 3.3 parts of the colorant (6) or 4 parts of the colorant (10), respectively. When these compositions were added to the washing tank in the same manner as above, they provided blue washing water.
