摘要:
A silver halide photographic material comprising a support having thereon at least one photosensitive silver halide emulsion layer with the silver halide photographic material containing at least one compound, as an ultraviolet absorbing agent, represented by the general formula (I) ##STR1## wherein Z represents the atoms necessary for forming a pyrrolidine nucleus or a thiazolidine nucleus; R.sub.1 represents an alkyl group or an aryl group; R.sub.2 and R.sub.3, which may be the same or different, each represents a cyano group, a carboxy group, --COR.sub.4 or --COOR.sub.4 ; R.sub.4 represents an alkyl group or an aryl group; and n represents 1 or 2, and when n is 2, one of R.sub.1 and R.sub.4 represents an alkylene group or an arylene group, in which the compound is a dimer; and a method of preventing the effects of ultraviolet light on a silver halide photographic material comprising incorporating into the silver halide photographic material, as an ultraviolet light absorbing agent, at least one compound represented by the general formula (I) above.
