Includes the process of grasping.
  • the toilet training indicator is the growing state of the infant who is the wearer of the absorbent article. It shows different responses to urine, so that the guardian (mother, family, etc.) can grasp the guideline of the start time of toilet training.
  • the toilet training indicator is preferably within 1 minute after the urine is excreted by the wearer.

  • the urine of the toilet training indicator continues while the response of the toilet training indicator to urine continues. It is preferable that the response to is different depending on the growing condition of the infant who is the wearer. Therefore, in the method of grasping the guideline of the toilet training start time using the toilet training indicator or the toilet training indicator material of the present invention, it is preferable for 1 hour or more, more preferably 3 hours or more, still more preferable. It is preferable that the response of the toilet training indicator to urine differs depending on the growth condition of the infant who is the wearer for 12 hours or more.
  • Examples 1 to 6 and Comparative Examples 1 to 5 As the toilet training indicator, a detection composition showing a different response to the urine specific gravity value was used, and the response of the indicator to urine and the success or failure of the toilet training were evaluated.
  • the success or failure of potty training can be determined if, as a result of potty training, you can spend at least during the day without diapers (if you can graduate from diapers during the day), and if you can spend all day without diapers, including at night. If the condition was reached (if the diaper could be graduated), it was evaluated as a successful toilet training.
  • the state of graduating from a diaper means that it is now possible to excrete in a general toilet at will.
  • the diapers used in Examples and Comparative Examples have an absorbent article, and the absorbent article includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and a top sheet and a back sheet.
  • the toilet training indicator according to the present disclosure was applied to a back sheet having an absorbent layer as an absorber arranged between them and as a toilet training indicator material. Specifically, the toilet training indicator is directly applied to the back sheet and dried and used as the toilet training indicator material, or the toilet training indicator held on the carrier is adhered to the back sheet. Was used as an indicator material for toilet training.
  • an indicator capable of measuring urine specific gravity was used as an indicator for toilet training. Specifically, a reagent composition containing bromothymol blue and methyl red as pH indicators, polyoxyethylene sorbitan monolaurate (Tween 20) as a surfactant, and TES as a pH buffer was used.
  • the specific density of urine was measured by referring to the degree of color development of the toilet training indicator in the absorbent article of the diaper that absorbed urine with respect to the color swatch.
  • the specific gravity of urine was quantified in the range of 1.000 to 1.0350, and the average value of the specific gravity of urine measured during the evaluation period was taken as the average specific gravity of urine.
  • Urine specific gravity was measured for 2 years and 2 months (26 months old) to 3 years and 4 months (40 months old) infants wearing the above-mentioned diapers over an evaluation period of 2 to 4 days, respectively. At the same time, toilet training was conducted and the success or failure of toilet training was evaluated.
  • Table 1 shows the age of the infant, the average urine specific gravity during the period of toilet training, and the results of toilet training. The results of the training were shown as " ⁇ " when the training was successful (when the diaper could be graduated) and "x" when the training was unsuccessful (when the diaper could not be graduated).
  • Comparative Example 1 and Example 1 show the results for the same infant. At the time when the average urine specific gravity was 1.0261 (Comparative Example 1), the diaper could not be graduated even after toilet training, but when the average urine specific gravity was 1.0306 (Example 1). In), it can be seen that diapers could be graduated by performing toilet training.
  • Comparative Example 3 and Example 2 also show the results for the same infant, and the same can be said.
  • the urine specific gravity value increases with the development of renal function, it is considered that there is some correlation between age (month age) and urine specific gravity.
  • age and urine specific gravity is weak, and in fact, even when looking at Table 1 above, there are cases where the urine specific gravity value is relatively high despite the relatively young age (Example 6 and the like).
  • the urine specific gravity value is relatively low even if the age is relatively high (Comparative Examples 2, 3 and the like). Therefore, even if there is a certain degree of correlation between age and urine specific gravity, it is not possible to determine when to start toilet training using only age as an index instead of urine specific gravity. It is clear from. Rather, the urine specific gravity value provides an index that cannot be read from age in determining that the infant is at a developmental stage suitable for potty training.
