両側面に取りつけてある粘着テープの粘着力が低
下したり、あるいは粘着力が強すぎて紙オムツ外
面の軟質樹脂フイルムを破断したりして、再着用
が困難であつた。 However, conventional disposable diapers cannot be recognized from the outside even when wet, so they are often left wet for a long time, and when they are removed and checked each time, the adhesive strength of the adhesive tape attached to both sides of the disposable diaper decreases. Alternatively, the adhesive force was so strong that the soft resin film on the outer surface of the disposable diaper was broken, making it difficult to wear it again.

感じを与えることがあるという問題があつた。 In order to solve these problems, the inventor
By providing a printing layer containing a water-soluble resin as a binder and a highly hygienic coloring agent on the inside of the soft resin film on the outer surface of the paper diaper or on the surface of the paper diaper, the printing layer becomes more stable when wet. Invented a paper diaper that can be identified by bleeding (Akira Jitsukai)
58-184505), although this invention makes identification extremely easy, there is a problem in that the eluted printing ink may spread into the inside of the disposable diaper, giving it an unsanitary appearance.

を併用する方法がある。 The water-insoluble resin layer 2, which is transparent or translucent when wet and opaque when dry, used in the present invention may be of any type, such as nitrocellulose, cellulose acetate, ethyl cellulose, cellulose acetate butyrate. It can be obtained by whitening cellulose resins such as. In this case, whitening methods include mixing water with the printing solvent, mixing a fast-drying polar solvent with an ester solvent,
Alternatively, there is a method of humidifying the printing surface, or a method of using these methods in combination.

ましい。 Any colored ink that is water-insoluble after drying may be used; for example, water-based ink is suitable. Vehicles for such water-based inks include, for example, water-soluble resins such as styrene-acrylic resins, styrene-maleic resins, styrene resins, acrylic resins, vinyl acetate resins, styrene-butadiene resins, and alkyd resins. Although there are water-dispersible resins such as resins and epoxy resins, styrene-acrylic water-dispersible resins are preferred because they have good film-forming properties, relatively quick drying properties, and good adhesion to the soft resin film 1. Further, the colorant for such colored ink may be any water-insoluble colorant, and is preferably selected from organic pigments and inorganic pigments, but is preferably one that is harmless even if it comes into direct contact with the skin. In order to improve the water permeability of the colored ink layer, extender pigments such as barium sulfate, calcium carbonate, kaolin, and silica can be added. It is preferable to use
