Heterogeneous Foam Materials Having a Graphic Printed Thereon

摘要

The present disclosure relates to homogeneous or heterogeneous polymer foam structures having a graphic printed thereon. As discussed herein, foam structures, such as for example High Internal Phase Emulsion (HIPE) foam structures may include a first surface and a second surface opposite the first surface, and one or more graphics may be printed directly on the first and/or second surfaces of the foam. The graphic may comprise ink positioned on the first and/or second surface, wherein the ink may penetrate into the foam structure below the surface on which the ink is applied. As such, the ink may reside on the foam structure and/or within the foam structure at various depths below the first and/or second surface.

主权项

1. A heterogeneous polymeric foam structure comprising:
interconnected open-cells obtained from at least one water-in-oil emulsion; at least two distinct regions that differ by at least about 20% with regard to microcellular morphology; and a graphic printed on at least one of the two distinct regions.
