60557-2975 Abstract of the Disclosure Microencapsulated materials are released by rupturing of an adhesive layer on a substrate containing the capsules. The novel article comprises two sheets or opposed faces of a folded single sheet which are temporarily bonded by means of an adhesive with rupturable microcapsules dispersed therein and on the exterior surface of one or said sheets is an adhesive layer. The microcapsules are ruptured by pulling apart the sheets after they are first adhered to another surface which causes the capsules to rupture and release the ingredients contained therein. By selecting the relative physical properties of the sheet, adhesive, capsules and the binding forces amongst them, a high rate of capsule rupturing can be obtained consistently. The materials may be used, for example, in pull-apart fragrance-releasing sheets.
