ABSTRACT:
A compressible printing element that has a thermosol lamina. A thermosol is a thermosetting plastisol, preferably a polyvinyl chloride plastisol containing dioctyl phthalate as a plasticizer and having a di- or tri-acrylate monomer that crosslinks therewith to form a thermoset material preferably in the presence of a peroxide free-radical initiator activated by heat. A phenolic resin is preferably included in the thermosol. The thermosol lamina is resilient and adhered to a compressible lamina, preferably one that is highly porous.
