Abstract (en)

A silver halide photographic material that contains a polymer including a repeating unit represented by the following general formula (I) and having a weight average molecular weight of no more than 30,000: <CHEM> where R<1> is a hydrogen atom or an alkyl group; Z represents the atomic group necessary to form a lactam ring, an oxazolidone ring or a pyrrolidone ring; A is a simple linkage, -CO-, -COO(CH2 @@@ or -CONR<2>(CH2 @@@ where R<2> is a hydrogen atom or an alkyl group, and n is an integer of 1 - 6. This photographic material experiences a minimum level of increase in fogging during rapid processing and produces image having improved sharpness and granularity.
