Abstract
Abstract A PHOTOSENSITIVE MEMBER WHICH INCLUDES A BINDER LAYER CONSISTING OF PHOTOCONDUCTIVE PARTICLES DISPERSED IN A RESIN MATRIX. THE BINDER LAYER IS FORMED BY APPLYING A BINDER COATING MIXTURE MADE UP OF FINELY-DIVIDED PHOTOCONDUCTOR PARTICLES, AN ALKYD RESIN, AND A METHANOL MODIFIED BENZOAGUNAMINE RESINOUS MATERIAL TO A SUPPORTING SUBSTRATE TO FORM A BINDER LAYER. THE BINDER LAYER IS THEN CURED AT A TEMPERATURE BETWEEN ABOUT 80 AND 100* C. TO CAUSE A CONDENSATION REACTION BETWEEN THE ALKYD AND BENZOGUANAMINE RESINS.
