发明名称 Method of preparing monodisperse tabular-grain silver halide emulsion, and photographic material comprising the same
摘要 A method of preparing a silver halide emulsion is disclosed, comprising a disperse medium and silver halide grains, said method comprising the steps of: (1) forming silver halide tabular grains for the silver halide emulsion in the presence of at least one polymer having repeating units represented by formula (1), (2) subsequently to the step (1), removing the polymer by washing with water, and (3) using as seed crystals the silver halide tabular grains obtained via steps (1) and (2) and further growing these grains;-(R-O)n-(1)wherein each R represents an alkylene group having 2 to 10 carbon atoms, and n is an average number of repeating units which ranges from 4 to 200, and further a silver halide photographic material is disclosed, comprising the above silver halide emulsion.
