本発明は、分散安定性がよく、微生物発生のない水性黒

生抑制剤を適宜添加していたものであった。(Prior Art) Conventionally, microbial generation inhibitors are generally added to aqueous pigment inks for writing instruments and recorders in order to prevent the generation of microorganisms. For this method, if the amount added is too large, the dispersion stability will be poor, and the microbial generation inhibitor will precipitate and the pigment will coagulate, resulting in scratches in the handwriting and ink breakage.If the amount added is too small, the effect will not be sufficient. Therefore, the amount to be added was determined empirically, and at the time of compounding, a microbial generation inhibitor within the range of this amount was added as appropriate.

の含有量を、特定することか要望される。(Problem to be solved) However, it is not possible to confirm the content of the microbial generation inhibitor after it has been blended, and as a result, it is difficult to determine how much of the microbial generation inhibitor is actually working in the ink. However, I am not sure if it is appropriate. In particular, when a carbon blank is used as a pigment, the microbial generation inhibitor is adsorbed, and the amount of the microbial generation inhibitor that actually acts is smaller than the amount added at the time of formulation. In addition, the amount of microbial growth inhibitor adsorbed and changes over time in the adsorbed amount vary depending on the type of carbon black, and even if microorganisms occur over time, it is unknown how much the microbial growth inhibitor has decreased. After blending, it is required to specify the content of the microbial growth inhibitor.

The analysis sample concentration is 0.025 g/Q, the measured absorption peak is in the range of 245 to 350 nm, and the absorbance ABS value at this absorption peak is 0.05 to 1.5. It is something to do.
