7  US 2017/0014278 Al  Jan. 19, 2017  [0061]  The manufacture of substrates, absorbent articles  and structural components thereof, for use herein form no  part of this invention. The following discussion is for  [0060]  In one embodiment of the present invention, the  wetness indicator composition of the present invention may  be on and/or in a substrate. When present on a substrate, the  wetness indicator composition will typically be placed on  and/or in a substrate where the substrate will be contacted by  a liquid, such as water, urine, menses, blood and the like.  The substrate may include, but is not limited to, woven  fabrics, nonwoven fabrics, films, sponges, and combinations  thereof. The substrate may comprise synthetic and/or natural  materials. In one embodiment of the present invention the  optional substrate may be an article in its own right, such as,  a continuous nonwoven fabric. In another embodiment of  the present invention the substrate to which the wetness  indicator may be applied or otherwise affixed comprises any  one, or a combination of, structural components of an  absorbent article, including, but not limited to, the back› sheet, topsheet, fasteners, absorbent material, etc., or may be  a separate element added or applied to the product. In one  optional embodiment of the present invention the wetness  indicator composition is applied to the absorbent article as a  whole.  Substrate  [0062]  In one embodiment of the present invention the  disposable absorbent article is a disposable diaper. Typically,  modern disposable diapers comprise a liquid pervious top› sheet a liquid impervious backsheet; an absorbent core  which may be positioned between at least a portion of the  topsheet and the backsheet; side panels; elasticized leg cuffs;  an elastic waist feature; and a fastening system. In one  embodiment opposing sides of the disposable diaper may be  seamed or welded to form a pant. This allows the article to  be used as a pull-on type diaper, such as a training pant.  Additional illustrative, but non-limiting, information on  construction, assembly, and the various components (includ› ing backsheets, dusting layers, upper and lower covering  sheets, and webs) of disposable diapers may be found in  U.S. Pat.
