Abstract:
A primer layer that includes a surface-tension modifier dispersed within a polymer binder is disposed between the imaging layer and the substrate of a lithographic printing member to inhibit the production of thermal degradation products that disrupt the oleophilicity of the exposed imaged areas, thereby improving print-making performance and efficiency. In addition, embodiments of the primer layer inhibit static charge buildup during production and during the print-making process.
