Patent

CA 2174734

A method for imparting topographical features to a permanent substrate employing a sheet material comprising a thermosettable pressure-sensitive adhesive composition. The edges of the sheet material are caused to flow prior to the thermosetting reaction to provide smooth transition lines between an exposed surface of the sheet material and the permanent substrate.

L'invention se rapporte à un procédé permettant de produire des structures en relief sur un substrat permanent à l'aide d'un matériau en feuille comprenant une composition adhésive autocollante et thermodurcissable. Les bords du matériau en feuille sont amenés à fluer avant la réaction de durcissement thermique afin de produire des lignes de transition régulières entre une surface exposée du matériau en feuille et le substrat permanent.
