Abstract
An article is comprised of a thermoset polymer having a dye sublimation image in a layer attached or integral to a surface of the thermoset polymer, wherein at least a portion of the thermoset polymer is a foam. The foam article may be made by pretreating a thermoset organic polymer foam to a temperature of 100° C. to about 250° C. for a time sufficient to stabilize the thermoset polymer and dye sublimating an image into a layer of the pretreated thermoset foam. The foam article having the dye sublimation image may be used for applications having aesthetic or structural requirements such as railing, decking or fences.

A method of forming an article comprising,
- (i) pretreating a thermoset organic polymer wherein at least portion of said polymer is a foam by heating to a pretreatment temperature of about 100° C. to about 250° C. for a time sufficient to stabilize the thermoset polymer to form an initial article,
- (ii) dye sublimating an image into the initial article to form an article having a dye sublimation image in a layer attached thereto or integral therewith.
