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

Abstract SU 1384057 A1

FIELD: light-sensitive materials. SUBSTANCE: composition contains, wt. %: triphenylamine, 39.0-59.75; sensitizer, 0.50-9.09;and polymer binder, the balance. Sensitizer may be malachite green, 2,7- bis(diethylamino)phenoxazonium perchlorate, or 2,4-di(p- ethoxyphenyl)-6-(p-methoxystyryl)pyrilium tetrafluoroborate. Polymer binder may be polysulfone based on 4,4Т-dihydroxydiphenyl-2,2-propane and 4,4-dihalodiphenylsulfone. This composition in suitable solvent is poured on nickel-plated polyethylene terephthalate support to form layer with thickness 2 to 20 mcm. EFFECT: improved quality of layer due to increased general light sensitivity and light transmission in the region 365-400 nm. 1 tbl
