摘要：
A silver halide photographic material comprises at least one silver halide emulsion layer provided on a support. The silver halide emulsion layer contains a color coupler. According to the present invention, the color coupler is contained in particles of a specific polymer dispersed in the silver halide emulsion layer. The specific polymer comprises repeating units represented by the formula (I): ##STR1## in which R.sup.1 is hydrogen, a halogen atom or an alkyl group having 1 to 4 carbon atoms; each of R.sup.2 and R.sup.3 is an aliphatic group or an aromatic group, or R.sup.2 and R.sup.3 are combined with the oxygen atoms and the phosphorus atom to form a heterocyclic ring; and L is a divalent linking group selected from --CO--, --O--, --S--, --NR.sup.4 --, --SO.sub.2 --, a divalent aliphatic group, a divalent aromatic group and a combination thereof, and R.sup.4 is hydrogen or an aliphatic group.
