（産業上の利用分野）
本発明は、おむつが尿などによって濡れた場合、それを
肉眼で容易に検知することのできる使い捨ておむつに関
する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a disposable diaper that can be easily detected with the naked eye when the diaper becomes wet with urine or the like.
（従来技術）
最近、木綿のおむつに代わって、持ち運びが便利で使い
易い、使い捨ておむつが主流を示すようになってきた。(Prior Art) Recently, disposable diapers, which are convenient to carry and easy to use, have become mainstream in place of cotton diapers.
このような使い捨ておむつは一般に外側（肌に接する側
）に水透過性シート、その内側に尿吸収部材を保有し、
更にその上に水不透過性シートがあり構成されている。Such disposable diapers generally have a water-permeable sheet on the outside (the side that contacts the skin) and a urine-absorbing member on the inside.
Furthermore, there is a water-impermeable sheet on top of it.
前記した水不透過性シートはおむつカバーを兼ねるもの
であり、内部の尿のよごれがはっきり見えない方がよい
ため一般に半透明のプラスチックシートが用いられてい
る。The water-impermeable sheet described above also serves as a diaper cover, and generally a translucent plastic sheet is used because it is better not to clearly see urine stains inside.

固定ができなかった。(Problem that the invention is trying to solve) When covered with such a translucent plastic sheet cover, it is difficult to judge the amount of urine with the naked eye, so it is necessary to remove the diaper and check it by hand. Moreover, once the simple fixing cloth and adhesive tape were removed, it could not be firmly fixed the second time.

本発明に到達した。(Means for solving all the problems) In view of the above, the inventors of the present invention have conducted various studies in order to obtain a disposable diaper that develops color when wet with urine etc.
A substantially colorless printing ink was prepared in which a small amount of a water-soluble dye was dispersed in a water-absorbing polymer, a hydrophobic binder, and a hydrophobic organic solvent, and a pattern was formed on a plastic sheet using this printing ink. The present invention was achieved based on the finding that this pattern is almost colorless before coming into contact with water or the like, but becomes brightly colored when the pattern is moistened with water or urine.

め染料の色は殆ど認められない。(Effects) The disposable diaper of the present invention has a pattern printed on the surface in contact with the urine absorbing member using ink mainly containing a water-soluble dye, a water-absorbing polymer, and a hydrophobic binder. When this printed pattern comes into contact with urine, etc., the dye is eluted and the color develops for the first time, so the color of the dye is hardly recognized before it is wetted with urine, etc. because the amount of dye is small.

たがって、この発色模様によっておむつの尿による濡れ
の程度を外から容易に判断することができる。Furthermore, since a water-absorbing polymer is present in the printed pattern, it has good water retention, and even if the dye develops color when it comes into contact with urine, the colored part will not fade and the printed pattern will not become blurred. Therefore, the degree of wetting of the diaper with urine can be easily determined from the outside based on this colored pattern.
