ABSTRACT:
A photographic light-sensitive material which has on a support at least one silver halide emulsion layer containing large-size silver halide grains formed in the presence of at least one compound acting as a silver halide solvent and having the following general formual (I): ##STR1## wherein l and m each represents an integer of 2 or 3; n represents zero or an integer of 1 or 2; and R.sup.1 and R.sup.5 may be the same as or different from one another, each being an alkyl group, a hydroxyalkyl group or carboxyalkyl group, and when n equals zero, at least one of the substituents of R.sup.1 to R.sup.4, must be a hydroxyalkyl group, while when n does not equal zero, at least two of the substitutents of R.sup.1 to R.sup.5, must be hydroxyalkyl groups. Use of the compound of the present invention results in emulsions exhibiting excellent reproducibility with respect to gain sizes of silver halides.
