Kasserbare papirprodukter med indikerende midler

摘要

Disposable paper products, such as paper toweling, are provided with an indicator means which is disposed on said disposable paper product in a discontinuous or combination discontinuous/continuous pattern. The indicator means gives a visually recognizable signal to a user that desirable properties of the disposable paper product are maintained, even after the disposable paper product has become wetted with a substantially transparent aqueous liquid. The wet gray scale difference for the disposable paper product of the present invention is at least about 64 gray scale units when the disposable paper product is wetted with a substantially transparent aqueous liquid.
