Zusammenfassung:	An improved process for preparing a light-sensitive silver halide photographic material and a photographic material produced thereby are disclosed which comprises incorporating, into a gelatinous photographic emulsion, liquid-containing fine capsules which are obtained by preparing an aqueous liquid composed mainly of a first reactant and a water-immiscible liquid composed mainly of a first reactant and a water-immiscible liquid composed mainly of a second reactant capable of forming a polymer by reaction with said first reactant, and dispersing as fine drops either one of said liquids into the other liquid to form a polymer according to polycondensation reaction of said first reactant with said second reactant which takes place at the interface between the two liquid, so that the surfaces of said fine drops are coated with the thus formed polymer.
