摘要:
A light-sensitive silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, with the silver halide photographic material containing at least one compound represented by the following general formula (I): ##STR1## wherein Z represents the atoms necessary to complete an oxazolidine ring, a pyrrolidine ring or a thiazolidine ring; R.sup.1 and R.sup.2, which may be the same or different, each represents an alkyl group or an aryl group; R.sup.3 represents a --COR.sup.4 group or a --CO.sub.2 R.sup.5 group; R.sup.4 represents an alkyl group or an aryl group; R.sup.5 represents a hydrogen atom, an alkyl group or an aryl group; and n is 1 or 2, and when n is 2, at least one of R.sup.1, R.sup.4 and R.sup.5 represents a divalent alkylene group, a divalent arylene group or a divalent group of alkylene and arylene moieties to form a dimer; and a method for preventing the effects of ultraviolet light on a silver halide photographic material comprising incorporating, as an ultraviolet light absorbent, at least one compound represented by the general formula (I) above into the silver halide photographic material.
