ABSTRACT:
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: ##STR1## wherein R.sup.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(CH.sub.2).sub.n or --CONR.sup.2 (CH.sub.2).sub.n where R.sup.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.
