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

Abstract SU 1384056 A1

FIELD: light- sensitive materials. SUBSTANCE: solution is prepared containing plasticized poly-N-(2,3-epoxypropyl)carbazol and sensitizer Ц thiapyrilium salt of general formula: where X is BF4; R1 phenyl, 2-naphthyl, or 4-ethoxyphenyl; R2 4-methoxyphenyl, 4-ethoxyphenyl, 4-(dimethylamino)phenyl, 4-fluorophenyl, or 4-chlorophenyl; R3 phenyl, 2-naphthyl, 4-methoxyphenyl, or methyl; n=0 or 1. Sensitizer is used in quantity 1-5 wt % in appropriate solvent. Solution is poured on conducting backing and dried. EFFECT: improved quality of layer due to increased general light sensitivity and/or degree of panchromatic property within 400-700 nm range. 1 tbl
