Abstract
An adhesive wafer, which is especially suitable for use as a faceplate for an ostomy appliance but may also be used as a wound dressing, has an adhesive layer of hydrocolloid-containing skin barrier material and a flexible backing layer extending over one surface of the adhesive layer. The opposite skin-contacting surface of the adhesive layer is embossed to provide a pattern of discrete, non-connecting depressions separated and isolated from each other by flat-topped ridges dimensioned and arranged so that a skin surface engaged by said embossed surface primarily contacts only such ridges.
