Abstract

1317139 Photographic silver halide emulsions FUJI PHOTO FILM CO Ltd 15 May 1970 [17 May 1969] 3502/73 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 0‹2 micron in diameter and contain at least one sensitizing dye of the formula:- wherein Z completes a 5-membered or 6-membered heterocyclic ring (e.g. tetrahydropyrole, thiazolidine, benzthiazole, benzoxazole); Q completes a ketomethylene heterocyclic ring (e.g. rhodanine); R is alkyl, substituted alkyl or allyl; each L is CH or C(R<SP>1</SP>) (where R<SP>1</SP> is substituted alkyl or substituted aryl); R may be attached through a polymethylene chain to the L nearest to the hetrocyclic ring containing Z; and m is 1 or 2.
