The invention relates to a base comprising a closed cell foam core sheet having a closed cell foam layer with a density gradient between the center of the core and the surfaces of the core. The invention also relates to a method of making such a base by adding a first concentration of a first blowing agent to a first polymer to form a first mixture, adding a second concentration of a second blowing agent to a second polymer to form a second mixture, and extruding the mixtures to form the closed cell foam core sheet. The invention also relates to a method of making such a closed cell foam core sheet base comprising the steps of adding a blowing agent to a polymer to form a mixture, melting the mixture, extruding the mixture from a die, and rapidly quenching the mixture against a high heat transfer surface.

The base comprises a foam core layer, which comprises a polymer that has been expanded through the use of a blowing agent, and at least one polymeric surface smoothing layer, which comprises a solution polymer.
摘要:
An image receiving element is a composite of two or more extruded layers on a support including, in order, an extruded compliant layer, an extruded antistatic tie layer, and an image receiving layer that may also be extruded. The extruded compliant layer is non-voided and comprises from about 10 to about 40 weight % of at least one elastomeric polymer. This image receiving element can be disposed on a support to form a thermal dye transfer receiver element, an electrophotographic image receiver element, or a thermal wax receiver element. Two or more extruded layers can be co-extruded.
