Abstract
Abstract The invention relates to a imaging member comprising at least one imaging receiving on the top of said member and at least one image receiving layer on the bottom of said member, a polymer sheet comprising at least one layer of voided polyester polymer and at least one layer comprising nonvoided polyester polymer, wherein the imaging member has a percent transmission of between 38 and 42%, the imaging member further comprises tints, and the nonvoided layer is at least twice as thick as the voided layer.
