Abstract

1317140 Photographic silver halide emulsions FUJI PHOTO FILM CO Ltd 15 May 1970 [17 May 1969] 3503/73 Divided out of 1316493 Heading G2C Photographic silver halide emulsions having increased sensitivity in the specific adsorption wavelength of the silver halide and which also have an enlarged spectral adsorption wavelength region, have a mean silver halide grain size smaller than 0À18 micron or have at least 95% of the silver halide grains smaller than 0À2 micron in diameter and contain at least one sensitizing dye of the formula:- wherein Q is O, S or N(R<SP>4</SP>) (where R<SP>4</SP> is alkyl, substituted alkyl, aryl or allyl); Z<SP>1</SP> and Z<SP>2</SP> each complete a 5- or 6-membered heterocyclic ring (e.g. oxazole, benzoxazole, thiazole, benzthiazole, naphthothiazole, quinoline, tetrazole); R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are each alkyl or substituted alkyl; L<SP>1</SP>, L<SP>2</SP> and L<SP>3</SP> are each CH or C(R<SP>5</SP>) (where R<SP>5</SP> is alkyl, alkoxy, aryl or substituted aryl); R<SP>1</SP> and L<SP>1</SP> or R<SP>3</SP> and L<SP>3</SP> may be joined through a polymethylene chain; X is an anion; m is 0 or 1; and n is 0 or 1, the dye being an intromolecular salt when n is 0.
