ABSTRACT:
Flaring phenomenon in electrographic recording can be substantially reduce, if not eliminated, forming uniform latent image spots by providing a flaring suppressor agent in or on the surface of the dielectric charge retentive layer of the electrographic recording medium. The improvement comprises incorporating a flaring suppressor agent in the composition of the dielectric charge retentive layer of the electrographic recording medium or coating a flaring suppressor agent on the surface of the dielectric charge retentive layer of the electrographic recording medium to enhance the charge retentive properties of the layer and quench lateral electrical discharge breakdown during recording use thereof. A suitable flaring suppressor agent comprise fluoro carbons or fluoro sulfurs or organo metallic salts or soaps. Specific examples of agents are polyvinyl fluoride, sulfur hexafluoride or zinc stearate.
