Abstract

1400149 Photographic silver halide materials AGFA-GEVAERT 30 Oct 1972 [10 Nov 1971] 52290/71 Heading G2C [Also in Division C2] Photographic silver halide emulsions having improved image-sharpness contain a compound of the Formula:- wherein R is hydrogen or acyl e.g. acetyl, haloacetyl, R 1 is hydrogen, alkyl, aryl, halogen or alkoxy and R2 is an aliphatic, aromatic or heterocyclic group e.g. 1-phenyl-5-tetrazolyl, 2-benzthiazolyl, 1-phenyl-3-triazolyl, phenyl or benzyl. The emulsions are preferably Lippmann emulsions.
