ABSTRACT:
A process for fabricating an electrostatographic imaging member including providing a flexible substrate comprising a solid thermoplastic polymer, forming an imaging layer coating including a film forming polymer on the substrate, heating the coating and substrate, cooling the coating and substrate, and applying sufficient predetermined biaxial tensions to the substrate while the imaging layer coating and substrate are at a temperature greater than the glass transition temperature of the imaging layer coating to substantially compensate for all dimensional thermal contraction mismatches between the substrate and the imaging layer coating during cooling of the imaging layer coating and the substrate, removing application of the biaxial tension to the substrate, and cooling the substrate whereby the final hardened and cooled imaging layer coating and substrate are substantially free of internal stress and strain.
