COMPOSITION OF LIGHT-SENSITIVE LAYER OF ELECTROPHOTOGRAPHIC MATERIAL Russian patent published in 1999 - IPC

Abstract SU 1410693 A1

FIELD: light-sensitive materials. SUBSTANCE: light-sensitive layer is applied onto flexible conducting backing, layer being composed of 22.62-90.0 wt % of organic photoconductor - poly-N-vinylcarbazol, or poly-N-(2,3-epoxypropyl)carbazol, or 3,6-dichloro(or bromo)-poly-N- (2,3-poxypropyl)carbazol; 0.33-1.15 wt % of sensitizer - 2,4,7- trinitrofluoren-9-one or pyrilium salt; and polymer binder - polysulfone based on 4,4'-dihydroxydiphenyl-2,2'-propane and 4,4'- dihalodiphenylsulfone or polycarbonate based on 4,4'- dihydroxydiphenyl-2,2'-propane (the balance). EFFECT: improved quality of layer due to its increased optical transmission in 365-400 nm region and number of material bends. 1 tbl
