Problems solved by technology

[0007] However, as mentioned above, the discoloration speed of the existing diapers according to the change of pH is relatively slow, and in order to fix the litmus paper or the paper stained with the indicator on the inner cover or the outer cover of the diaper, it is necessary to use an adhesive.
In addition, the litmus paper or the paper stained with the indicator will come off from the inner cover or outer cover of the diaper, making it difficult to judge by pH changes

Abstract

The present invention relates to a composite film which is discolored according to a pH change and a diaper comprising the same, wherein the liquid impermeable air-permeable film layer and the liquidimpermeable air-permeable film layer are coated with a water- The present invention provides a composite film which can be immediately discolored according to a change in pH, by including a discoloration layer using an aqueous ink composition comprising an organic acid, a solvent, a silane compound, and a binder. Also, the present invention provides a diaper comprising a composite film that is discolored according to the pH change, wherein the protector can instantly observe the feces discharge of the wearer from the outside by the naked eye, thereby improving convenience and usability of theprotector and the wearer.

Description

technical field [0001] The present invention relates to a composite film that changes color according to pH changes and a paper diaper including the composite film that changes color according to pH changes. Background technique [0002] A liquid-impermeable gas-permeable film refers to a film having the property of being permeable to gases and water vapor but impermeable to liquids. Micro-unit-sized air holes are evenly distributed inside the air-permeable film, and whether liquid can penetrate is determined by the air holes. Generally speaking, the liquid-impermeable breathable film is used for diapers, sanitary napkins, disposable cold and waterproof products and other sanitary products, agricultural products, construction supplies, etc., among which, it is mainly used for disposable diapers, which can not be controlled in size. Defecation and defecation of infants or patients with reduced mobility. [0003] This disposable diaper comprises an outer cover, an absorbent ...
