Abstract
A silver halide photographic light-sensitive material containing in at least one of its constituent layers a polymerized stabilizer which comprises repeating units having an 1,2,4-triazolo[1,5-a]pyrimidine moiety. The stabilizer does not inhibit the sensitivity of the material and greatly enhances its storability.
