ABSTRACT:
A process of preparing a radiation-sensitive silver halide emulsion is disclosed in which a polyalkylene oxide block copolymer surfactant is employed. Dispersion of the polyalkylene oxide block copolymer surfactant in the aqueous dispersing medium is increased by the inclusion of an auxiliary surfactant. The auxiliary surfactants are selected from among those that, in the form of an aqueous solution containing 10 percent by weight of the auxiliary surfactant based on total weight of the aqueous solution, is miscible in all proportions with at least one of water and the polyalkylene oxide block copolymer surfactant.
