PHOTOSENSITIVE LAYER OF ELECTROPHOTOGRAPHIC MATERIAL Russian patent published in 1998 - IPC

Abstract SU 1362303 A1

FIELD: photosensitive materials. SUBSTANCE: composition contains, wt %: poly-N-epoxypropylcarbazol, 91.0-98.0; 2,4,7-trinitrofluorenone or 2,4,5,7-tetranitrofluorenone (sensitizers), 1.5-6.8; pyrilium salt of tetrafluoroborate of 2,4-diphenyl-6[beta-ethenyl-(N- propylcarbazolyl)] or 2,4-di(p-bromophenyl)-6[beta-ethenyl-(N- propylcarbazolyl)] or dye 2,7-bis(diethylamino)phenoxazonium perchlorate, or their mixture, the balance. EFFECT: improved quality of layer due to increased degree of panchromaticity in the region of 400-700 nm, increased common photosensitivity, and extended region of spectral sensitivity. 1 tbl
