Abstract
A silver halide photographic light-sensitive material comprising a support having thereon at least one photographic silver halide emulsion layer. The light-sensitive material contains at least one hydrophilic organic colloid layer in which at least one photographically useful reagent is dispersed in the presence of a specific surface-active polymer. The polymer contains at least 5 mole % of units represented by the following general formula (I-1) or (I-2): ##STR1## wherein R.sub.1 represents a substituted or unsubstituted alkyl, alkenyl or aryl group having 1 to 30 carbon atoms, A and D each represents a single bond or a divalent linking group, R.sub.2 represents a substituted or unsubstituted alkyl or aryl group, R.sub.3 and R.sub.4 each represents hydrogen or a substituted or unsubstituted alkyl or aryl group, R.sub.2 and R.sub.3 or R.sub.3 and R.sub.4 may respectively form a ring, X represents a single bond or a substituted or unsubstituted alkylene, alkenylene or arylene group, Y represents --COOM, --SO.sub.3 M, --O--SO.sub.3 M or ##STR2## in which M represents hydrogen or an inorganic or organic cation, m.sub.1 is an integer of 1 to 3, and m.sub.2 is 1 or 2. This photographic light-sensitive material does not contaminate processing solutions, and gives an image of good quality.
