LIGHT-SENSITIVE LAYER OF ELECTROPHOTOGRAPHIC MATERIAL Russian patent published in 1998 - IPC

Abstract SU 1354979 A1

FIELD: light- sensitive materials. SUBSTANCE: quality of electrophotographic material is improved owing to increased panchromatic capacity in the region 400-700 nm, general light sensitivity, and extended spectral region of light sensitivity of layer. Layer contains, wt.%: poly-N- epoxypropylcarbazol, 91.0-95.2; 2,4,7-trinitrofluoren-9-on or 2,4,5,7-tetranitrofluorene, 2.4-4.5; parafuchsin picrate, 1.2-2.3; and picrate of malachite green or methylene blue, 1.2-2.3. EFFECT: improved quality of material. 1 tbl
