Description

  The present invention relates to an absorbent article such as a disposable diaper.

  Conventionally, disposable diapers have been provided with an indicator that determines by color whether or not the wearer has excreted. Disposable diapers having an indicator that is judged by a scent are also known so that a visually impaired person can judge. For example, Patent Document 1 describes a disposable diaper having a fragrance-diffusing layer having a water-soluble resin layer containing a volatile substance having a fragrance-diffusing property between an absorber and a back sheet. . Patent Document 2 describes a disposable diaper in which microcapsules each having a different fragrance component are disposed in each of a urine receiving portion and a stool receiving portion.

  In the disposable diaper described in Patent Document 1, when excrement such as urine comes into contact with the fragrance-diffusing layer, a volatile substance having a fragrance-dissipating property is volatilized and discharged to the outside of the diaper, resulting in excretion. It is perceived. Therefore, it can be determined that not only healthy subjects but also visually impaired people have excreted. However, in the disposable diaper described in Patent Document 1, it is difficult to satisfy the need to determine whether it is time to replace the diaper based on the amount of excreted matter absorbed.

  The disposable diaper described in Patent Document 2 had urination or defecation because fragrance components of the microcapsules arranged in the urine receiving part and the stool receiving part differed when urination or defecation contacted the microcapsule. It is perceived. Therefore, it can be judged that not only healthy subjects but also visually impaired people had urination or defecation. However, Patent Document 2 does not describe any means for knowing the amount of excreta absorbed, and in the disposable diaper described in Patent Document 2, it is determined whether it is time to replace the diaper. It cannot be judged by the amount of things.
