  • Heat-transferable security stamp
    Patent number: 6733867
    Abstract: A heat-transferable security stamp is provided including a carrier sheet, a top coat layer, at least one design layer between the carrier sheet and the top coat layer, a release layer between the carrier sheet and the design layer, and a base coat layer between the release layer and the design layer. The release layer includes a water-borne release component. The base coat layer includes a water-borne base coat component. The design layer includes a water-borne design component. The top coat layer includes a water-borne top coat component. The carrier sheet is resistant to heat above a predetermined heat transfer temperature. The adhesive release component of the release layer is operative to secure the carrier sheet to the base coat layer at temperatures below the heat transfer temperature and to permit release of the carrier sheet from the base coat layer at temperatures above the heat transfer temperature.

  • Simulated security thread by cellulose transparentization
    Patent number: 6607813
    Abstract: A security document is provided comprising a finished cellulosic substrate having at least one transparentized portion formed therein. The transparentized portion comprises a transparentizing composition that is applied so as to define an area of increased transparency in the substrate. The area of increased transparency includes at least one thin line and resembles a simulated security thread. The transparentizing composition can be applied to form thin lines in a variety of configurations on one or both sides of the substrate.

  • Process for the formation of a heat-transferable security stamp entirely free of non-aqueous solvents
    Patent number: 6410082
    Abstract: A heat-transferable security stamp is provided including a carrier sheet, a top coat layer, at least one design layer between the carrier sheet and the top coat layer, a release layer between the carrier sheet and the design layer, and a base coat layer between the release layer and the design layer. The release layer includes a water-borne release component. The base coat layer includes a water-borne base coat component. The design layer includes a water-borne design component. The top coat layer includes a water-borne top coat component. The carrier sheet is resistant to heat above a predetermined heat transfer temperature. The adhesive release component of the release layer is operative to secure the carrier sheet to the base coat layer at temperatures below the heat transfer temperature and to permit release of the carrier sheet from the base coat layer at temperatures above the heat transfer temperature.
