Abstract

1340126 Trimethine dyes FUJI PHOTO FILM CO Ltd 19 April 1971 [16 Feb 1970] 21940/71 Heading C4P [Also in Divisions G2-G3 and H1] A sensitizing trimethincyanine dye is represented by formula in which Z and Z<SP>1</SP> each represent the atoms necessary to complete a benzothiazole nucleus, a benzoselenazole nucleus or a naphthothiazole nucleus, R and R<SP>1</SP> each represent alkyl, e.g. ethyl, n-propyl; carboxyalkyl, e.g. #-carboxyethyl, γ-carboxy butyl, #-carboxybutyl and #- carboxypentyl; or sulphoalkyl, e.g. γ-sulphopropyl, γ-sulphobutyl and #-sulphobutyl, at least one of R and R<SP>1</SP> being carboxy- or sulphoalkyl, X- is an anion and n is 0 when an intramolecular salt is formed or 1. Z and Z<SP>1</SP> may be substituted by Cl, Br, CH 3 , CH 3 O, C 2 H 5 O, OH and phenyl.
