Abstract

1471701 Photographic silver halide material FUJI PHOTO FILM CO Ltd 2 Oct 1974 [2 Oct 1973] 42832/74 Heading G2C Photographic silver halide material suitable for exposure by a neon-helium laser comprises a silver halide emulsion having grains of at least 0À2 microns and in which at least 90% of the silver halide has a cubic or tetradecahedral crystal habit, said emulsion containing a dye of the Formula: wherein Z and Z'each completes a 5- or 6-membered nitrogen-containing heterocyclic ring which may be substituted and/or have another ring or rings fused thereto, e.g. thiazole, benzthiazole or naphthothiazole, R and R' are each saturated or unsaturated aliphatic hydrocarbon groups which may be substituted, Q and Q' in combination complete a 4-thiazolidinone, 5-thiazolidinone or 4-imidazolidinone nucleus, L<SP>1</SP>, L<SP>2</SP> and L<SP>3</SP> are each methine or substituted methine of the formula = C(R<SP>2</SP>)- where R<SP>2</SP> is alkyl which may be substituted or aryl, or L<SP>1</SP> and R and/or L<SP>3</SP> and R<SP>1</SP> are linked by a methylene chain to form a heterocyclic ring, X# is an anion and each of m, n and p is 0 or 1.
