Abstract 1. THE METHOD OF PREPARING THE ELECTRI-SIGNAL-RESPONSIVE FILM FOR A RECORDING BLANK, WHICH METHOD COMPRISES (A) PREPARING A CONTINUITY-STRUCTURE-PROVIDING SUSPENSION COMPRISING CARBON BLACK PARTICLES DISPERSED IN A FILM-FORMING MULTI-PHASE RESIN-COMPLEX COMPRISING AS ITS ESSENTIAL CONSTITUENTS A CONTINUITY-STRUCTUREPROVIDING FILM-FORMING RESIN EFFECTIVE FOR SAID SIGNALRESPONSIVE FILM AND A VOLATILE ORGANIC SOLVENT WHEREIN THE RESIN CONTENT OF SAID COMPLEX IS ONLY PARTIALLY DISSOLVED THEREBY TO PROVIDE IN SAID MULTI-PHASE RESIN-COMPLEX FROM ABOUT 20 TO ABOUT 80 PERCENT OF ITS RESIN CONTENT IN PARTICULATE FORM AS AT LEAST ONE MEMBER OF THE CLASS CONSISTING OF (I) SOLID PARTICLES AND (II) INDIVIDUAL PARTICLES SWELLED WITH IMBIBED SOLVENT, SAID INDIVIDUAL PARTICLES IN THE DRY STATE FREE OF SOLVENT BEING FROM ABOUT 1 TO ABOUT 50 MICRONS IN SIZE; AND (B) APPLYING A LAYER OF SAID SUSPENSION OVER A SURFACE WHEREON THE DESIRED SIGNAL-RESPONSIVE FILM IS TO BE FORMED, AND ALLOWING THE VOLTALIE SOLVENT CONTENT OF SAID LAYER TO EVAPORATE OFF.
