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

Abstract SU 1438481 A1

FIELD: photosensitive materials. SUBSTANCE: photosensitive layer is prepared by conventional technique from mixture composed of, wt %: poly-N-epoxypropylcarbazol, 94.0-98.9; pyrilium salt or derivative of 2,2-difluoro-1,3,2-dioxyborine with absorption maximum 400-500 nm, 1.0-3.0; pyrilium salt or dye with absorption maximum 600-700 nm, 0.1-3.0. EFFECT: improved quality of layer due to increased optical transmission in the region of 360-400 nm and spectral sensitivity in the region of 400-500 nm. 1 tbl
