Abstract
An imaging member is prepared by applying to a support a heat-sensitive imaging layer which comprises at least one heat-sensitive polymer capable of undergoing transformation from a hydrophilic to hydrophobic state or hydrophobic to hydrophilic state, wherein the transformation occurs such that the activation energy Ea and the Arrhenius pre-exponential factor A associated with the transformation simultaneously fulfill the relationships: ln (A).gtoreq.0.4 Ea+8.84 and ln (A).ltoreq.1.69 Ea-14.37. The imaging member is useful in processless thermal lithographic printing.
