ABSTRACT:
A multilayer sheet material that is capable of being adhered to a foamed polymer core material is prepared from at least four layers, which are a first outer layer of a printable sheet material, an inner layer of a fibrous sheet material, an inner layer of an adhesive material, and a second outer layer of a weldable sheet material. Stiff foam polymer core articles, such as body boards, having detailed designs on them can be prepared by welding the multilayer sheet material to a foamed polymer core material.
