Abstract

1353264 Photographic sensitizing dyes MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 Aug 1972 [25 Aug 1971 4 Got 1971] 39290/72 Heading C4P Trimethine dyes for sensitizing electrophotographic layers containing an organic photoconductor are of formula (in which R 1 is H or phenyl; R 2 is H, phenyl, 4- methoxyphenyl, naphthyl or 2- or 4-methoxynaphthyl-(1); R 3 is H, NO 2 , methoxy or phenyl; R 4 is H or methoxy; X is O or S; Y is anion). The dyes are prepared by a conventional condensation reaction. The examples describe their use in sensitizing layers of polyacenaphthalene, poly-N-vinyl carbazole and a mixture of brominated poly-N-vinylcarbazole and polycarbonate, which may be plasticized with chlorinated diphenyl.
