  • Article containing microencapsulated materials
    Patent number: 4898633
    Abstract: Articles comprising a thermoplastic substrate bearing rupturable microcapsules in a binder on at least one surface thereof. These articles can be applied by means of heat and pressure to porous objects. The process of applying the articles to porous objects further results in partially embedding the microcapsules in the substrate. Thermoplastic substrates having rupturable microcapsules partially embedded therein, but not having a binder, are another aspect of this invention.
    Type: Grant
    Filed: July 15, 1988
    Date of Patent: February 6, 1990
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Richard H. Doree, Josef V. Ugro, Jr.
