Abstract

1402420 Photographic silver halide materials AGFA-GEVAERT 30 Oct 1972 [10 Nov 1971] 52289/71 Heading G2C [Also in Division C2] Photographic silver halide Lippmann emulsions having an average grain-size of less than 100 nm, are improved in image-sharpness and in lack of image distortion by incorporating a compound of the formula:- wherein R is hydrogen or acyl e.g. acetyl or chloroacetyl, R 1 is an aliphatic, aromatic or heterocyclic group e.g. phenyltetrazolyl, benzimidazolylmethyl, benzothiazolyl, p-nitro-phenyl, benzyl or hexadecyl, and R2 is hydrogen, the group -SR 1 , or alkyl, aryl, halo, hydroxyl or alkoxy e.g. methyl. The Lippmann emulsion may be chemically and optically sensitized and may contain a dye to reduce light scatter. Reference has been directed by the Comptroller to Specification 1058606.
